Upgrade to private, an EC, or a bigger home — with the sums done first.
The part that trips people up isn’t the buying — it’s the ABSD, the sequencing and the financing. We model all three before you commit, so you upgrade without overpaying or being caught between two homes.
In short
- 1.The bank’s limit is not your budget. Banks test your repayments at 4% interest; your real instalment is lower, but the interest you pay over the whole loan is the number to look at.
- 2.Sell first, buy first, or both at once: each order changes the cash you need, whether you pay 20% Additional Buyer’s Stamp Duty upfront, and where you live in between.
- 3.Moving HDB to HDB? The contra facility lets the sale pay for the purchase on the same day.
- 4.Your options are a bigger HDB resale flat, a new EC, a resale condo, a new launch, keeping the flat and buying private, or (for private owners) decoupling. They differ in cash, loan rules, timing and lock-in.
- 5.Start with the budget calculator, then bring the result to a review. Mortgage advice itself comes from your bank or a mortgage banker.
Path 1
I own an HDB flat and want to move to private or an EC
You’ll need to have met your Minimum Occupation Period, and the maths shifts with an EC — income ceiling, resale levy, a longer wait before you can sell — versus a resale condo. We map your affordability, the ABSD you would front and can reclaim, and how your CPF refund from the flat sale funds the deposit.
Plan my HDB-to-private movePath 2
I already own private and want a bigger home
Here it turns on ABSD and sequencing: buy first and you front the tax, reclaimable only if you sell within six months and meet every condition. Decoupling, bridging and Seller’s Stamp Duty all come into it. We model the cash and the timeline before you commit.

How much home can you afford next?
A comfortable and a maximum price, the monthly repayment, and the cash and CPF needed upfront — with what selling your current home adds. Then read on for the rules behind the numbers.
Free. No signup. Plain English, with the working shown.
Seller’s Stamp Duty was raised and extended on 4 July 2025. Sell within four years of buying and it applies on a sliding scale — enough to change whether upgrading now is worth it. If you bought recently, it’s the first number to check. See the numbers
Can we afford it?
Can we afford it, and what does it really cost?
Two different questions. The first is what the bank will lend. The second is what you will actually pay each month and over the life of the loan, and whether that still feels comfortable if rates rise or one income stops.
Most the bank will lend
All your monthly debt repayments, including car loans and the minimum on credit cards, must stay within 55% of gross monthly income (the Total Debt Servicing Ratio). For an HDB flat or an EC still in its occupation period, the home loan alone must also stay within 30% (the Mortgage Servicing Ratio).
The loan is also capped at 75% of the price, falling to 55% if the loan runs past age 65 or beyond the longest standard tenure. If you still have a housing loan running, the cap is 45% and at least 25% must be paid in cash.
The bank’s test rate vs your real instalment
Banks check the limits above as if your loan charged 4% a year (3% for an HDB loan), to be sure you could cope if rates rose. Your actual instalment is worked out at the rate you are offered, which is usually lower. Both matter: the test rate decides the loan; the real rate decides your monthly budget.
On an example loan of $1,000,000 over 30 years:
- $4,774 a month
- At the bank’s test rate (4%)
- $3,951 a month
- At an illustrative rate of 2.5%
What the loan really costs: total interest
The monthly figure hides the total. Over the full tenure, interest adds a large sum on top of the loan, and a longer tenure lowers the instalment but raises the total.
- $345,850 total interest
- 25 years at 2.5% · $4,486 a month
- $422,435 total interest
- 30 years at 2.5% · $3,951 a month
- $718,695 total interest
- 30 years at 4% · $4,774 a month
Maximum vs comfortable
The calculator gives two prices. The maximum stretches to the bank’s limit. The comfortable price keeps all your monthly repayments within 30% of income (the share the rules allow for an HDB home loan alone), which leaves room for children, a rate rise, or a gap between jobs. We plan to the comfortable figure unless you tell us otherwise.
Check our budget with the calculator →Costs that are easy to miss
- Buyer’s Stamp Duty and legal fees, paid within days of signing.
- Additional Buyer’s Stamp Duty of 20% if you buy before selling (refundable only in the cases set out below).
- Interest on a bridging loan, and two homes’ running costs if the sale and purchase do not line up.
- CPF you use earns no interest for you, and is refunded with accrued interest when you sell the next home.
- Renovation and furnishing: usually paid in cash, and never from the housing loan.
- Cash over valuation on an HDB resale flat, which must be paid in cash.
We work out the housing numbers: limits, cash, stamp duty and timing. The loan package itself (rate, lock-in, fixed or floating) is advice from your bank or a mortgage banker, and we will introduce one if you want.

Timeline
Where do we stay? Sell first, buy first, or both at once.
The order you do things in decides the cash you need, whether stamp duty is paid upfront, and where your family sleeps in between. Here are the four ways to do it side by side.
Sell first, then buy
- Cash you need
- Lowest. The sale money and CPF refund pay the next downpayment, and the next loan can be up to 75%.
- Additional Buyer’s Stamp Duty
- None for a Singapore Citizen household: you own one home at a time.
- Where you live in between
- An extension of stay of up to 3 months on an HDB flat, but only if the next home is already bought and completed. Otherwise a rental (private homes: 3-month minimum) or family.
- Main risk
- Prices move while you search, and you may move twice.
- Suits
- Tight cash, buyers of a new launch or EC, anyone who wants certainty on the budget first.
Buy first, then sell
- Cash you need
- Highest. At least 25% in cash and a loan of up to 45% while the current loan runs, plus the stamp duty.
- Additional Buyer’s Stamp Duty
- 20% paid upfront. Refunded only to a married couple (at least one Singapore Citizen, buying jointly) who sell the first home within 6 months of completion, or of TOP for a home still being built.
- Where you live in between
- In your current home until the new one is ready. You move once.
- Main risk
- The refund deadline. If the old home sells slowly, the duty becomes a cost.
- Suits
- Strong cash, a married Singapore Citizen couple, and a home that will sell quickly.
Both at once (concurrent)
- Cash you need
- In between. Sign the sale and the purchase within days of each other, with completion dates lined up.
- Additional Buyer’s Stamp Duty
- Usually none if your buyer exercises the option on your home before you exercise yours. If not, the buy-first rules apply.
- Where you live in between
- Move straight across on completion day, or use the extension of stay on an HDB flat while you move.
- Main risk
- Two deals depend on each other. If one slips, the other needs a plan B (a bridging loan or a later completion).
- Suits
- Most upgraders buying a completed resale home, with an agent running both sides to one timeline.
HDB to HDB with the contra facility
- Cash you need
- Low. The sale proceeds and CPF refund pay for the next flat on the same day. Stamp duty and legal fees still need your own money.
- Additional Buyer’s Stamp Duty
- Remitted upfront when any buyer is a Singapore Citizen. The old flat must be sold within 6 months.
- Where you live in between
- Both flats complete on the same day; you can request an extension of stay in the flat you sold.
- Main risk
- Both buyer and seller must file within 7 days, and the other parties cannot be using contra themselves.
- Suits
- Families moving to a bigger HDB resale flat.
Your choices for the months in between
Extension of stay
HDB: up to 3 months after completion, with the buyer’s agreement, only when you have already bought a completed home. Private: agree it with the buyer and write it into the option. You reimburse the buyer’s costs for the period.
A longer completion
On a private sale, the completion date is negotiated. A longer one can bridge the gap without moving out early. HDB sets the HDB completion date, usually about 8 weeks after it accepts the resale application.
A short rental
A private home can be rented for as little as 3 months. Serviced apartments are more flexible but cost more.
Staying with family
The cheapest option, and common. Plan where your things go: storage and two moves cost more than most people expect.
Time it to TOP
Buying a new launch or EC? You can usually stay in your current home until the keys, then sell. For a condo that means the stamp-duty refund window starts at TOP; for a new EC, the HDB flat must be sold within 6 months of key collection.
When both happen at once, we run one timeline
- 1.Your bank’s approval in principle for the right loan (first or second) before any option is signed.
- 2.Option dates on both homes set so your buyer commits before you do, wherever the market allows.
- 3.HDB resale application timed with the extension of stay or contra request, which must go in with it.
- 4.Completion dates matched, with the lawyers on both sides working to the same date.
- 5.Bridging loan arranged in advance if needed; under MAS rules it sits outside the debt limit when repaid within 6 months.
- 6.The CPF refund and the stamp-duty refund tracked to the day, and a fallback written down if either deal slips.
Rules verified with HDB, IRAS and MAS on the date shown. HDB, IRAS and your bank assess each case; ask us for the month-by-month plan for your own move. Sources: HDB extension of stay · HDB contra facility · IRAS stamp-duty refund · MAS bridging loans.
Month by month
The same move, two orders — and very different cash flows.
Here is each order laid out month by month, with where you live in between and what it costs. The calculator lets you toggle between them with your own numbers.
Sell first, then buy
Your cash and CPF come back before you commit to the next home. The trade-off is where you live in between.
- Month 0Appraisal and proceeds estimate; list the flat. Shortlist the next home in parallel so you know what the budget buys.
- Month 1–2Buyer exercises the Option to Purchase on your flat. You now know the price and can size the next purchase exactly.
- Month 2–4HDB completes the resale, usually about 8 weeks after it accepts the resale application. Loan repaid, CPF refunded with interest, cash to you. An extension of stay of up to 3 months is possible only if you have already bought a completed home; otherwise plan a rental or stay with family.
- Month 3–5Exercise the option on the next home with the refunded CPF and cash as the downpayment. First housing loan at up to 75% of the price, with no other housing loan counted against your limit.
- Month 5–7Complete the purchase and move. For a new launch or new EC, this stretches to the project’s completion — plan the interim housing for that long.
- What it costs you
- No extra stamp duty, no bridging loan, full loan limit. The cost is the interim: an extension of stay (reimbursing the buyer’s costs), a short rental, or staying with family.
- Suits
- Most HDB upgraders and anyone with tight cash.
Buy first, then sell
You move straight from one home to the other. The trade-off is money: more cash upfront, a smaller loan, and extra stamp duty you claim back later.
- Month 0Exercise the option on the next home while still owning the flat. Pay Additional Buyer’s Stamp Duty upfront (20% of the price for a Singapore Citizen’s second home) on top of the usual stamp duty. A new EC from a developer is the exception: no upfront duty for Singapore Citizens.
- Month 0Second housing loan: capped at 45% of the price, with at least 25% in cash, and your current instalment still counts against your repayment limit. A bridging loan can cover the gap until the sale money arrives.
- Month 0–3Complete the purchase. The 6-month refund window starts now (from completion, or from TOP if the new home is still being built). List the flat immediately.
- Month 1–5Sell the flat: your buyer exercises the option, then the HDB resale application and completion. Cash and CPF refund arrive; repay the bridging loan.
- Within 6 monthsYour buyer must exercise the option on the flat inside the window. The refund goes to a married couple (at least one Singapore Citizen, bought jointly); IRAS refunds it automatically if you declared the plan to sell when stamping. Miss the window and the duty is simply a cost.
- What it costs you
- The extra stamp duty fronted for months, bridging-loan interest, a larger cash downpayment, and two sets of running costs until the flat sells. If the flat sells slowly, the refund window becomes the risk.
- Suits
- Households with strong cash, married with at least one Singapore Citizen spouse, confident the flat will sell quickly — and buyers of a new launch who stay in the flat until TOP.
Timings are typical for a resale-to-resale move and vary with the market and the buyer. HDB flats must have met the Minimum Occupation Period before either order is possible. Rules verified against IRAS, HDB and MAS; the bank and IRAS assess each case.
Upgrading options
Your upgrading options compared
Six ways to move up. They differ in the cash and loan rules, in how long you wait, and in what you can do with the home afterwards. Most families have two or three that work.
A bigger HDB resale flat
- Who it suits
- Families who need more room and want to stay in HDB.
- Cash and loan rules
- HDB or bank loan. The home loan must stay within 30% of income. Additional Buyer’s Stamp Duty is remitted for Singapore Citizen buyers.
- Timeline
- About 3 to 5 months. The contra facility lets both flats complete on the same day.
- Watch out for
- Cash over valuation is paid in cash. Sell the old flat within 6 months of completing the purchase.
A new Executive Condominium
- Who it suits
- Households earning up to $16,000 a month, with a Singapore Citizen applicant.
- Cash and loan rules
- No Additional Buyer’s Stamp Duty upfront for Singapore Citizens. Progressive payments while it is built. Home loan within 30% of income. Second-timers pay the resale levy in cash.
- Timeline
- Usually 3 to 4 years to keys. You stay in your flat until then.
- Watch out for
- Sell the HDB flat within 6 months of key collection. Occupation period of 5 or 10 years before you can sell.
A resale condo
- Who it suits
- Families who want to move within months, with no income ceiling.
- Cash and loan rules
- Sell first: loan up to 75%, at least 5% in cash. Buy first: 20% stamp duty upfront, a loan of up to 45% and 25% in cash.
- Timeline
- About 3 to 6 months, done concurrently.
- Watch out for
- The refund window runs 6 months from completion. Maintenance fees and the bank’s test rate.
A new launch condo
- Who it suits
- Buyers who can wait for completion and want a new home.
- Cash and loan rules
- Progressive payments, so interest starts small. Buying while you own the flat: 20% stamp duty upfront, refundable for a married Singapore Citizen couple if the flat is sold within 6 months of TOP.
- Timeline
- Usually 3 to 4 years to TOP. Live in the flat until then.
- Watch out for
- The stamp duty is tied up for years. No HDB extension of stay into an unfinished home, so plan the sale around TOP.
Keep the HDB flat and buy private
- Who it suits
- Singapore Citizen households with strong income and cash who want to keep the flat to let.
- Cash and loan rules
- 20% stamp duty, not refunded because you keep the flat. A loan of up to 45% and 25% in cash if the flat still has a loan; that loan counts in the 55% limit.
- Timeline
- Any time after the occupation period.
- Watch out for
- Households where all owners are permanent residents must sell the flat within 6 months. Check the rental yield covers the extra tax.
Decoupling (private owners)
- Who it suits
- Couples who jointly own a private home and want to buy a second.
- Cash and loan rules
- Buyer’s Stamp Duty on the share transferred, legal fees, and the remaining owner must carry the whole loan alone. The freed spouse then buys as a first-time buyer.
- Timeline
- About 2 to 3 months for the transfer, before the next purchase.
- Watch out for
- Not possible for HDB flats. IRAS can disregard arrangements made mainly to avoid stamp duty.
Timelines are typical, not promised. HDB, IRAS and your bank decide eligibility and limits. The decoupling calculator works out whether it pays for you. Decoupling calculator · IRAS: HDB flats and new ECs · HDB: buying private.
Three things upgraders get wrong
ABSD is refundable, so just buy first.
The refund is only for a married couple with at least one Singapore Citizen spouse, buying jointly, and only if you sell the first home within six months of completing the purchase (or of the new home’s TOP if it is still being built). IRAS does not extend that window. Miss it, or buy in one name, and the tax is simply a cost.
The bank approved the loan, so I can afford it.
Your borrowing is capped by the Total Debt Servicing Ratio and stress-tested at a rate well above today’s, and your loan-to-value drops sharply if the tenure runs past 65. Approval in principle is a ceiling, not a plan.
My sale proceeds are my deposit.
When you sell, the CPF you used plus accrued interest returns to your CPF account first. What reaches you in cash — and what you can actually put toward the next deposit — is usually well below what the sale price suggests. We work it out before you list.
The numbers that decide your upgrade
These are the figures and rules an upgrade turns on. They are current as verified; your eligibility and the exact amounts are assessed by IRAS, HDB and CPF Board.
Additional Buyer’s Stamp Duty
20%
On a second residential property. Refundable for a married couple (at least one Singapore Citizen spouse, buying jointly) who sell the first home within six months of completing the purchase, or of TOP for an uncompleted home.
OfficialBuyer’s Stamp Duty
1%–6%
On every purchase, charged progressively on the higher of price or market value. The top rate applies to the portion above three million.
OfficialSeller’s Stamp Duty
Up to 16%
If you sell within four years of buying, on a sliding scale by year held. In practice HDB sellers rarely pay it, because the Minimum Occupation Period is longer than that window.
OfficialLoan-to-value limit
Up to 75%
Up to this share of the price on a first housing loan, dropping if the tenure is long or the loan runs past age 65.
OfficialTotal Debt Servicing Ratio
55%
Your total monthly debt repayments are capped at this share of gross income, stress-tested at a floor rate above current market rates.
OfficialMinimum Occupation Period
5 years
Before you can sell your flat and upgrade. Ten years for Plus and Prime flats, and it applies whether or not you took grants.
OfficialEC income ceiling
$16,000 a month
Maximum amount. Actual eligibility and quantum are assessed by HDB and CPF Board.
Household monthly income limit for a new Executive Condominium bought from a developer.
OfficialResale levy
$15,000–$55,000
Maximum amount. Actual eligibility and quantum are assessed by HDB and CPF Board.
Only if your next home is subsidised — a BTO, a Sale of Balance Flats unit, or a new EC. Nothing is payable on an open-market resale purchase.
OfficialAmounts and rates change. Every figure above is checked against the source on the date shown, and your own position should be confirmed before you commit to a purchase.

How it works
- 01Week 1
Affordability and ABSD review
We work out what you can actually borrow under the Total Debt Servicing Ratio and your loan-to-value limit, the cash and CPF you will need, the Buyer’s Stamp Duty, and any ABSD you would front — and, for private owners, whether decoupling changes the maths.
- 02Week 1
Sequence and timeline
Sell first, buy first, or both at once? We weigh each against the ABSD refund window, any Seller’s Stamp Duty still running, the contra facility if you are moving HDB to HDB, and where you would live in between — then lay out what each order costs, in money and in stress, so you can choose.
- 03Weeks 2–6
Sell well, shortlist in parallel
We market your current home to fund the upgrade at the strongest price, and shortlist your next one alongside — resale condo, new launch or EC — so both sides move together rather than one waiting on the other.
- 04Weeks 6–16
Coordinate to completion
We hold both transactions to the timeline: option dates, completion, bridging if you buy first, and the CPF refund on your sale. The aim is simple — a plan that avoids paying for two homes at once.
What it costs
1% + 9% GST
Limited time Our usual fee is 2% — same service, same standards.
Of the selling price, payable only on completion. No upfront marketing charges.
Includes pricing from transacted records, professional photography, listings on the major portals, all viewings and buyer or tenant screening, negotiation, paperwork and handover. Nothing is charged upfront.
When upgrading isn’t the answer
Four times we would tell you to wait, or not to move at all.
The ABSD makes it uneconomic.
Fronting a tax you cannot reclaim can wipe out the gain from a bigger home. If you do not qualify for the refund and decoupling does not work for you, staying put — or renovating — may be the better return.
Your Minimum Occupation Period isn’t up.
You cannot sell your flat on the open market, or hold private property, until you have met it. We will give you the date and build the plan toward it rather than around it.
The Total Debt Servicing Ratio won’t stretch.
If the loan you need breaks the cap at the stress-test rate, the purchase will not complete. Far better to know that now than after you have paid an option fee.
A rate rise would stretch you.
Where rates sit today, but loans are stress-tested for a reason. If a normal rise would make the home uncomfortable, a smaller step up — or waiting — protects you.
Questions we get asked
Do I have to sell my HDB flat before buying private?
Not necessarily, but you must have met your Minimum Occupation Period before you can sell the flat or hold private property. If you buy the private home first while still owning the flat, Additional Buyer’s Stamp Duty is payable upfront; a married Singapore Citizen couple buying jointly can claim it back by selling the flat within six months. We plan the sequence either way, because the cash and the tax both hinge on it.
How much is ABSD, and can I get it back?
For a Singapore Citizen, the first residential property attracts none and the second attracts the rate shown above. It is refundable only for a married couple with at least one Singapore Citizen spouse, buying in both names, who sell the first property within six months of the purchase. IRAS does not grant extensions to that window. Single buyers do not qualify, except for the separate concession for single citizens aged 55 and above right-sizing to a lower-value home.
What is decoupling and does it help?
It means transferring one owner’s share of a jointly held property to the other, so the freed owner counts as a first-property buyer on the next purchase and avoids ABSD. It works in some cases, but the transfer itself attracts Buyer’s Stamp Duty on the share moved, carries legal costs, and the remaining owner must service the whole loan alone under the Total Debt Servicing Ratio. It is a calculation, not a default.
Should I sell first or buy first?
Selling first frees your cash, tells you exactly what you can afford, and avoids fronting ABSD — but you may need somewhere to live in between. Buying first is smoother to move, but you front the tax and often need a bridging loan. The right answer depends on your cash position, your loan headroom and your tolerance for moving twice. We cost both before you decide.
How much can I borrow?
Your loan is capped by the Total Debt Servicing Ratio on all your monthly obligations, stress-tested at a floor rate well above what you would actually pay, and by the loan-to-value limit on the property. That limit falls sharply if the tenure is long or the loan runs past your 65th birthday, which usually means a bigger cash and CPF contribution. Approval in principle from a bank is where this starts, not where it ends.
Can I buy an Executive Condominium?
A new EC from a developer has a household income ceiling, and second-timers pay their resale levy on purchase. Note the occupation period carefully: units in projects whose land sale tender closed on or after 8 May 2026 can only be sold on the open market after ten years, rather than the five that applies to earlier projects. An EC is usually cheaper than a comparable condo, but whether it wins depends on your numbers and how long you intend to stay.
Will I pay Seller’s Stamp Duty?
If you sell within four years of buying, yes, on a sliding scale by the year you sell — the holding period was extended and the rates raised for properties bought on or after 4 July 2025. HDB flat sellers rarely pay it in practice, because the Minimum Occupation Period is longer than the SSD window. For anyone who bought private recently, this is often the figure that decides whether to upgrade now or wait.
What is a bridging loan and do I need one?
It is short-term financing that covers the gap when you complete a purchase before your sale proceeds and CPF refund arrive. Most packages are interest-only and repaid out of the sale. Whether you need one, and for how long, falls out of the sequence we plan — it is a consequence of buying first, not a separate decision.
How much of my HDB sale actually funds the next deposit?
Less than the sale price. Your outstanding loan is repaid first, then the CPF you used plus the accrued interest it would have earned returns to your CPF account. What is left in cash, together with the CPF you can use again on the next purchase, is your real deposit. We calculate that figure before you list, because it sets the ceiling on what you can buy.
Do I pay a resale levy when I upgrade?
Only if your next home is a subsidised one — a BTO flat, a Sale of Balance Flats unit, or a new EC from a developer. Buy on the open resale market, or buy private, and no levy is payable. Where it does apply, the amount is fixed by the type of your first subsidised flat, not the home you are moving to.
How much will the loan really cost us in interest?
More than most people expect. On a $1,000,000 loan over 30 years at an illustrative 2.5%, the interest alone comes to about $422,435. A shorter tenure raises the instalment but cuts the total. The calculator shows the instalment at your own rate, and your bank or a mortgage banker can advise on the package.
Why does the bank test us at a higher rate than we will pay?
MAS requires banks to check that your repayments fit within the limits as if the loan charged at least 4% a year (3% for an HDB loan). It decides how much you can borrow. Your actual instalment is worked out at the rate you are offered, which is usually lower, so the bank’s figure is a ceiling and your real monthly cost sits below it.
If we sell first, where do we live?
Four choices: an extension of stay in the home you sold (HDB allows up to 3 months, but only when you have already bought a completed home), a longer completion on a private sale, a short rental (private homes have a 3-month minimum), or family. If you are buying a new launch or EC, you usually stay in your current home until the keys and sell then.
Can we sell and buy at the same time?
Yes, and it is what most upgraders do. We line up the option dates so your buyer commits before you do, and match the completion dates so you move straight across. HDB to HDB, the contra facility lets your sale proceeds and CPF refund pay for the next flat on the same day; stamp duty and legal fees still come from your own money.
Can we keep our HDB flat and buy a condo?
Singapore Citizen households can, once the occupation period is over. You pay 20% Additional Buyer’s Stamp Duty on the condo with no refund, and if the flat still has a loan, the condo loan is capped at 45% with 25% in cash. Households where all owners are permanent residents must sell the flat within 6 months of buying private.
Do we pay Additional Buyer’s Stamp Duty on a new EC while we still own our flat?
Not upfront, if any buyer is a Singapore Citizen: IRAS remits it for new ECs bought from a developer, because HDB requires you to sell the flat within 6 months of collecting the EC keys. A resale EC is treated like any private home.
Terms on this page, in plain English
- ABSD
- Additional Buyer’s Stamp Duty — an extra tax when you buy a home while still owning another (20% of the price for a Singapore Citizen’s second home).
- BSD
- Buyer’s Stamp Duty — the tax paid on every home purchase, in steps from 1% to 6% of the price.
- SSD
- Seller’s Stamp Duty — a tax for selling within a few years of buying; the rate falls each year and stops after the holding period.
- TDSR
- Total Debt Servicing Ratio — the bank’s limit on all your monthly loan repayments, 55% of your gross income.
- MSR
- Mortgage Servicing Ratio — for HDB flats and new ECs, the home loan repayment alone may not exceed 30% of gross income.
- LTV
- Loan-to-value — the largest loan as a share of the price; 75% for a first housing loan, less for a second.
- Stress-tested
- Banks check your repayments at a higher interest rate than you will actually pay (4% for bank loans, 3% for HDB loans), to be sure you could still cope if rates rose.
- Tenure
- How many years the loan runs. Longer tenures cut the monthly payment but must end by age 65 to keep the full loan limit.
- Approval in principle
- A bank’s indication of how much it would lend you, before you commit to a home. A ceiling, not a plan.
- OTP
- Option to Purchase — the seller grants the buyer a period (usually 14–21 days) to decide, for a small fee; “exercising” it makes the sale binding.
- Completion
- The day ownership and the balance of the money change hands — typically two to three months after the option is exercised.
- MOP
- Minimum Occupation Period — the years (usually 5) you must live in an HDB flat before you can sell it or own private property.
- EC
- Executive Condominium — a condo sold by a developer with HDB-style rules at first (income ceiling, occupation period), becoming fully private later.
- HFE
- HDB Flat Eligibility letter — HDB’s confirmation of what you can buy and borrow, needed before you can buy a flat or take an HDB loan.
- Plus / Prime
- Newer HDB flats in choicer locations that carry a 10-year occupation period and tighter resale and rental rules.
- CPF OA
- Your CPF Ordinary Account — the CPF savings you can use for a home.
- Accrued interest
- The interest your CPF savings would have earned had they stayed in CPF. It is refunded along with the CPF you used when you sell.
- Resale levy
- A fixed amount HDB charges when you buy a second subsidised flat (new flat or new EC). Not charged when you buy on the open resale market.
- Bridging loan
- A short loan that covers the gap when you complete a purchase before your sale money and CPF refund arrive.
- Contra
- Selling one HDB flat and buying another on the same day, so the sale proceeds pay for the new flat. Arranged through HDB’s Enhanced Contra Facility.
- Decoupling
- Transferring one owner’s share of a jointly owned home to the other, so the freed owner can buy the next home as a first-time buyer.
- Extension of stay
- When a seller stays in the home for a short period after completion, by agreement (HDB: up to 3 months).
- Cash over valuation
- For HDB resale, the amount a buyer pays above HDB’s valuation; it must be paid in cash.
Not quite your situation?
What will you walk away with?
Cash in hand and CPF returned after the loan, the CPF refund with interest, any seller’s stamp duty and fees — the number your upgrade budget starts from.
Should you decouple before buying the next one?
The stamp duty and fees to transfer one spouse’s share, the ABSD it saves on the next home, and the price at which it starts to pay off.

Some upgraders keep the HDB flat and let it after the Minimum Occupation Period. Check the real, after-tax yield before deciding.
