HDB loan or bank loan

Almost nobody buying an HDB flat pays cash. The real decision is which lender: HDB's own concessionary loan, or a bank loan. The two are governed by different rules, priced differently, and lock you in differently — and the choice is close to one-way. This page compares them on the actual mechanics, not on marketing, and covers what a buyer gives up either way.

The mechanics: two different lenders, two different rulebooks

The HDB concessionary loan is a mortgage from your own housing board, not a bank. Its interest rate is fixed by formula at 0.1 percentage point above the CPF Ordinary Account interest rate, which sat at 2.5% p.a. for the quarter from 1 July to 30 September 2026 — making the HDB rate 2.6%. It has run at 2.6% for years because the OA floor rate itself has not moved.

A bank loan is priced either as a fixed package or as a floating rate pegged to compounded SORA plus the bank's own spread. As of mid-2026, floating packages were quoted around 1.9%–2.3% all-in (3-month SORA near 1.19%, spreads of 0.8–1.2 percentage points), and one market guide reported bank fixed packages at about 1.65% against the HDB's 2.6% — a gap of roughly a percentage point in the banks' favour, for a borrower who can pass the bank's own credit assessment.

Rate is not the only thing that differs. HDB's loan carries no lock-in period and no early-repayment penalty at all. A bank loan typically locks you in for one to three years (a resale-market guide reported a 2-year standard), with an early-exit penalty of about 1.5% of the outstanding balance if you break it.

• Loan-to-value: both now cap at 75% of price or valuation — HDB cut its own ceiling from 80% to 75% for resale applications from 20 August 2024, matching the bank-loan limit.
• Downpayment: an HDB loan's 25% downpayment can be cash, CPF Ordinary Account, or a mix, with no compulsory cash slice. A bank loan's 25% needs at least 5% in cash; the rest can be cash or CPF.
• CPF Ordinary Account you keep back: with an HDB loan you choose, at the point of purchase, to retain up to S$20,000 in your OA. With a bank loan you can retain any amount, and change it anytime through the eHousing portal.
• Direction of travel: an HDB loan can be refinanced into a bank loan at any time. A bank loan can never be refinanced back into an HDB loan. The door only swings one way.

That one-way door is the single most consequential mechanical fact on this page: taking a bank loan forecloses the HDB option permanently, while taking the HDB loan keeps the bank option open for as long as you want it.

Eligibility

Since 2023 a prospective buyer applies for an HDB Flat Eligibility (HFE) letter before flat-hunting. One letter answers three separate questions at once: whether you're eligible to buy a new or resale flat, whether you're eligible for an HDB housing loan, and whether you qualify for a CPF Housing Grant — three different eligibility tests bundled into one document, which is exactly why this page keeps them apart below.

To buy a resale flat at all: you must be a Singapore Citizen or PR, at least 21, with at least one other SC or SPR in the application to form a family nucleus (an unmarried buyer living alone must be a citizen aged 35 or older, 21 if orphaned or widowed). Non-Malaysian SPR households sit inside a quota — 8% of the block, 5% of the neighbourhood — and every buyer must fit inside the Ethnic Integration Policy proportion for that block and neighbourhood.

Eligibility to buy the flat and eligibility for the HDB loan are not the same test. The concessionary loan has its own, narrower bar: you're not eligible if every applicant and co-applicant is a Permanent Resident — at least one must be a Singapore Citizen. You're also shut out if any applicant, co-applicant, spouse, or listed occupier owns or holds an interest in private residential, commercial or industrial property, or more than one market or hawker stall, anywhere in the world. An all-PR household, or a household with any private-property interest, goes to a bank by default — not by choice.

The Minimum Occupation Period is 5 years from legal completion for a standard flat, 10 years for a new or resale Plus or Prime flat, and 20 years for a flat bought under the Fresh Start Housing Scheme. None of this changes with your choice of lender — MOP attaches to the flat, not the loan.

Citizenship status: SC, PR, foreigner, FTA nationals

A foreigner cannot own an HDB flat, full stop. This is worth separating from a different, unrelated rule that gets confused with it: the Residential Property Act lists which property types a foreign person may buy without Land Dealings Approval Unit approval, and an HDB flat is on that list alongside a condominium unit and an EC. That RPA entry is about whether approval is needed under a foreigner-land-ownership statute — it says nothing about HDB's own Housing and Development Act eligibility rules, which simply do not admit anyone who is not a Singapore Citizen or Permanent Resident. RPA silence is not HDB eligibility; the two rules answer different questions and neither substitutes for the other.

A PR household can buy a resale flat (subject to the quota above) but can never get the HDB concessionary loan as an all-PR household — at least one applicant must be a citizen for the loan, even though PR-only households can buy the flat itself. An all-SPR household also cannot buy a new flat at all, and may only buy resale once every applicant and core occupier has held SPR status for at least three years.

Nationals of the United States, Switzerland, Liechtenstein, Norway and Iceland are taxed as Singapore Citizens under free-trade-agreement parity — but that parity is a stamp-duty rule (it governs ABSD, below), not an HDB-ownership rule. FTA parity does not touch the Residential Property Act, and it does nothing to change HDB's own citizen/PR-only eligibility. An American national who is not also a Singapore Citizen or PR cannot buy an HDB flat, no matter what rate of ABSD they'd pay if they could.

Taxes: BSD, ABSD, SSD, property tax, rental income

Buyer's Stamp Duty applies to an HDB flat the same way it applies to any residential property, on a progressive schedule: 1% on the first S$180,000, 2% on the next S$180,000, 3% on the next S$640,000, 4% on the next S$500,000, 5% on the next S$1,500,000, and 6% above S$3,000,000. On a S$500,000 flat that's S$9,600; most HDB resale transactions clear entirely within the 1–3% bands.

Additional Buyer's Stamp Duty only bites if you or your co-buyer already own residential property. For a Singapore Citizen it's 0% on a first property, 20% on a second, 30% on a third and beyond; for a PR, 5% / 30% / 35%; for a foreigner (where eligible to buy at all), 60% flat; for an entity, 65%. Since a foreigner can't buy an HDB flat and a PR household with any private-property interest can't get the HDB loan, the ABSD question on this page usually only matters for someone who owns private property already and is buying an HDB flat as a second home — an unusual, and taxed, position.

Seller's Stamp Duty runs 16% in year one, 12% in year two, 8% in year three, 4% in year four, nil after, for any residential property (HDB included) bought on or after 4 July 2025. In practice SSD rarely touches an HDB exit: the standard Minimum Occupation Period is 5 years, and SSD's own holding period is 4 — by the time you're legally allowed to sell, the SSD clock has already run out for almost every buyer. It only matters if you inherited or otherwise acquired the flat within the SSD window and then also clear MOP inside four years, which is rare.

Property tax on an owner-occupied flat runs a progressive Annual Value schedule from 0% (first S$12,000 of AV) up to 32% (above S$140,000 AV) — in practice a modest bill for most HDB flats, whose AVs sit well below the top bands. Owner-occupier rates apply to only one property per owner; rent out the whole flat, or own a second home you occupy, and the higher non-owner-occupier schedule (12% to 36%) applies instead. A one-off 2026 rebate gives owner-occupied HDB flats 15% off their property tax bill for the year.

Rent out a room or the whole flat after MOP and the rental income is taxable. You can claim actual deductible expenses — fire insurance among them — or take IRAS's deemed 15% of gross rent in place of actual expenses; IRAS guidance also lets a landlord deduct repair, maintenance and property tax for a period the unit sat genuinely vacant while you made reasonable efforts to re-let it. None of this is available before MOP, since whole-flat subletting isn't permitted until then.

Borrowing: LTV, TDSR, MSR, and the actual HDB-versus-bank arithmetic

The Mortgage Servicing Ratio caps monthly loan repayments at 30% of gross monthly income, and it applies only to HDB flats and executive condominiums within their Minimum Occupation Period. This is the one ceiling that binds identically whichever lender you pick — an HDB loan and a bank loan on the same flat are both tested against the same 30% MSR.

What differs is the floor rate each lender stress-tests at, and whether the Total Debt Servicing Ratio applies at all. A bank loan is also tested under TDSR, 55% of gross income, at whichever is higher of a 4% floor rate or the loan's actual reversion rate. The HDB concessionary loan is not subject to TDSR — HDB assesses its own loan only against MSR, at its own 3% assessment floor. A worked example on a S$500,000 flat at 75% LTV (a S$375,000 loan): the HDB loan, assessed at a 3% floor over 25 years, needs about S$1,780 a month, requiring roughly S$5,930 of household income at the 30% MSR cap. The same loan through a bank, MSR-tested at MAS's 4% floor, needs about S$1,980 a month, requiring roughly S$6,600 of income — about 11% more income for the identical loan, purely because of the floor rate used to size it.

Loan-to-value is no longer a point of difference: both cap at 75% since HDB brought its own ceiling down to match the bank limit in August 2024. Maximum tenure is 25 years for an HDB flat either way (30 years for other property types), or a lower LTV applies if the tenure would run past age 65.

On price, a bank has recently been cheaper: fixed packages around 1.65% and floating packages around 1.9–2.3% against the HDB's steady 2.6%. But price is not the only variable priced into the choice. The HDB loan carries no lock-in and no exit penalty; a bank loan typically locks you in for one to three years with roughly a 1.5%-of-balance penalty to break it early, and its rate reprices at the end of that lock-in, exposing you to wherever SORA and the bank's spread sit then. The HDB rate is set by policy and doesn't move with the market at all.

Because the door only swings from HDB to bank and never back, the asymmetric move for a buyer who is eligible for both and genuinely undecided is to start on the HDB loan and refinance to a bank later if the rate gap holds up — you give up the very cheapest bank-fixed rate available today to keep the option open. Whether that trade is worth it depends on how much of today's roughly one-percentage-point gap you expect to still be there when you'd actually switch, and on how much you value not being locked into a rate reset you don't control.

Renovation: where this page's version of control lives

An HDB flat cannot be added-and-altered or rebuilt the way a landed home can — the structure belongs to HDB's own building-control regime, not to a URA planning-permission process, and there is no scope to extend the footprint or rebuild the unit. Renovation is the only lever of control an HDB owner has over the physical asset, and it runs entirely in cash: CPF savings cannot be used for renovation, improvement or repair work under any circumstance, no exceptions listed anywhere in CPF Board's own guidance. Whatever you spend on hacking, tiling or built-ins comes out of pocket or out of a separate renovation loan — never out of the mortgage or CPF.

Conveyancing

A resale flat can be conveyed by a private lawyer, typically S$1,500 to S$3,000 all-in, or through HDB's own in-house legal service, which runs a fixed scale — 13.5 cents per S$100 on the first S$30,000, 10.8 cents per S$100 on the next S$30,000, 9 cents per S$100 thereafter — and commonly comes in under S$1,000. On top of the legal fee, a resale buyer pays fixed disbursements: title search S$32, transfer registration S$38.30, buyer's caveat S$64.45, and (with an HDB loan) mortgage registration and mortgagee's caveat of a similar size each.

CPF's Ordinary Account can pay the stamp duty and the legal fee in full, but the HDB option fee and application fee — reported at S$10 to S$80 — must be paid in cash regardless of which loan you eventually take.

One quiet mechanical difference: documents for private property have been lodged electronically with the Singapore Land Authority since January 2006, while HDB property documents are still lodged manually at SLA's office — a paperwork artefact of HDB's separate administrative track, not something either loan changes.

Estate

If CPF pays any part of your monthly instalment, the Home Protection Scheme is compulsory: mortgage-reducing insurance against death, terminal illness and total permanent disability, premiums deducted annually from the Ordinary Account, cover running to age 65 or until the loan is paid off, whichever comes first. This applies whichever lender you chose, as long as CPF is servicing the loan; cash-only payers are strongly encouraged to carry equivalent cover but are not compelled to.

Separately, HDB Fire Insurance is compulsory for a flat owner with an outstanding HDB loan, runs in five-year terms, and covers only reinstatement of the HDB-built structure and fixtures — not your belongings. It must be bought with cash; CPF cannot pay for it.

On death, the CPF refund obligation on whatever OA savings funded the flat is waived automatically — the estate doesn't have to repay CPF's principal-plus-interest before the property can pass on. The flat itself still has to clear HDB's own ownership rules in the hands of whoever inherits it: immediate family, at least 21, at least one Singapore Citizen or PR among the new owners, and not already owning another HDB, DBSS or EC flat. An heir who already owns one must dispose of either the inherited flat or their existing one within six months.

The twelve questions

Two questions sort every reader before the twelve below apply, and neither is "are you buying to invest or to stay" — nobody buys believing the asset will fall, so that question sorts nobody.

Q1: are you borrowing to buy? For almost every reader of this page, yes — an HDB flat bought entirely in cash is rare. Q2: once you hold it, are you lending it out? For an HDB flat, almost never at the start: owner-occupation is a condition of the flat itself, and whole-unit subletting isn't permitted until MOP clears, and even then only with HDB's approval. That puts most HDB buyers squarely in one quadrant: borrow plus own-use — negative carry by construction, whether the lender is HDB or a bank.

C0 — the play

A balance-sheet play, not a cash-flow one. You are not buying the flat for income; you're buying somewhere to live while a compulsory mortgage forces savings into an asset.

C1 — balance sheet

What you own is the flat; what you owe is a loan at up to 75% LTV, HDB or bank. Which lender you pick doesn't change this line — only the shape of the liability underneath it.

C2 — cash flow

Money moves out every month, nothing moves in until (and unless) MOP clears and you sublet with HDB's consent. The funding gap is the difference between the assessed rate and what your own cash and CPF can carry: an HDB loan sizes against a 3% floor and 30% MSR; a bank loan against a 4% floor and the same 30% MSR — the same income supports a smaller loan at the bank.

C3 — P&L

Your paper equity moves with resale prices and with the flat's remaining lease, which decays every year by construction — an HDB flat is a wasting asset in a way freehold private property is not. That P&L line moves independently of your monthly cash flow, which only moves on repayment days.

C4 — carry

Negative by construction, per Q1/Q2 above. Choosing HDB's certain 2.6% over a bank's currently cheaper rate, or the reverse, changes how negative the carry is — it never changes the sign.

C5 — give / get

Take the HDB loan and you give up today's cheaper bank rate to get certainty and a reversible choice. Take the bank loan and you give up that reversibility to get, for now, a lower rate.

C6 — exposed to

An HDB loan exposes you to nothing but your own ability to keep paying — the rate is set by policy, not by markets. A bank loan exposes you to SORA and the bank's own spread every time your lock-in comes up for renewal.

C7 — for how long

MOP runs 5 years for a standard flat (10 for Plus/Prime, 20 under Fresh Start) before you can sell or rent out the whole unit. The mortgage itself can run up to 25 years either way.

C8 — failure cascade

A bank-rate rise (or a household income shock) deepens the negative carry, which squeezes monthly cash flow; sustained, that shows up as arrears on the P&L; at 75% LTV, a resale-price fall of just over a quarter (before costs) puts you underwater; an underwater flat inside MOP is illiquid by law, not just by market conditions; in the worst case, a forced mortgagee sale follows. The HDB loan removes the first domino — the rate never moves — but every domino after it is identical whichever lender you chose.

C9 — liquidity

Illiquid by design before MOP, and slow by market reality after: HDB's own resale process runs at least 8 to 10 weeks once you're legally free to sell at all.

C10 — control

Limited, and this is where the reno spoke above lives: you can't rebuild or extend an HDB flat, and even switching lenders only runs one way, HDB to bank. The one lever fully in your control is which loan you start with — which is exactly why this page exists.

C11 — the exit

Selling before MOP isn't just illiquid, it's not legally available outside narrow HDB-approved exceptions. After MOP, exit costs are conveyancing and agent fees plus, if CPF was used, the principal-and-accrued-interest refund to your own CPF account that comes off the top of proceeds. Seller's Stamp Duty is usually moot by exit time, since its 4-year window has already run out before a 5-year MOP does — one of the few places where two rules on this page interact instead of just sitting side by side.

Who this transaction employs

Financing an HDB flat runs through more parties than just you and HDB: a CEA-registered agent if you use one, a bank or the HDB loans branch, a conveyancing lawyer or HDB's own in-house legal service, and CPF Board administering the Ordinary Account movements throughout. A mortgage broker, if you use one to shop bank packages, is paid a referral commission by the bank on loan disbursal — not by you — and that fee is disclosed under MAS rules rather than added on top of your rate. That's worth knowing before assuming a broker's recommendation is free of any incentive at all: they're paid to place you with a bank, not to tell you the HDB loan might be the better fit.

What the agent earns, and where the incentive points

CEA sets no fixed commission rate for any property type, including an HDB resale transaction — the amount is negotiated and documented before the agent starts work, and paid to the agency, not directly to the agent. An agent cannot represent and collect commission from both the buyer and the seller in the same deal; that's an offence. An exclusive agreement ties you to one agency for up to three months, and you can still owe commission if you sell yourself or through another agent inside that window, with liability extending a further three months for anyone introduced during it. Median reported agent income sits around S$72,000 a year, but new agents often earn S$10,000 to S$40,000 in their first year — a spread wide enough to explain why an agent's own cash-flow pressure, not just yours, can shape how hard they push you toward closing quickly. On the financing question specifically, most agents have no direct stake in HDB loan versus bank loan — their commission comes from the sale, not the financing — but ask directly whether they earn a referral fee for introducing you to a particular bank or mortgage broker. If they do, that's a second, separate payment stacked on top of the first, and it points the same way every time: toward whichever lender pays the referral, not necessarily toward whichever loan suits you.
