HDB Home Loan vs Bank Loan: 2026 Singapore Comparison

By Dan Ler, Mortgage Advisor

HDB at 2.6% p.a. you set once and forget. Bank fixed from 1.40% p.a. is cheaper on paper, but only if you keep repricing it. Here is how the two stack up for HDB flat buyers in 2026.

The Headline Trade-Off

Every HDB buyer faces the same choice: take the HDB concessionary loan at 2.6% p.a., or take a bank loan from 1.40% p.a. On the numbers, the bank wins. The catch is what it asks of you afterwards.

HDB stays at 2.6% for the full tenure. No lock-in, no repricing, no paperwork. A bank loan starts cheaper, then resets to a board rate of 3.50%–4.50% p.a. or higher once the lock-in expires. To keep the savings, you have to reprice or refinance every 2–3 years.

HDB Concessionary Loan: Rate, LTV, Down Payment

The HDB loan is pegged at the CPF Ordinary Account rate plus 0.10%. CPF OA is 2.5%, so the HDB loan rate is 2.6% p.a. It has sat there since January 2008.

The catch is eligibility. At least one buyer must be a Singapore Citizen. Household income is capped (S$14,000 for families, S$21,000 extended, S$7,000 for singles). You can't own any private residential property, and you can't have taken two prior HDB loans. The HFE Letter tells you whether you qualify before you commit to anything.

• Max LTV is 75% (cut from 80% on 20 August 2024 to bring it in line with the bank loan).
• Down payment is 25%, fully payable from CPF OA, so zero cash out of pocket.
• No lock-in, and no penalty for paying it down early.
• MSR 30% applies, but there's no MAS 4% stress test on the HDB loan itself.

Bank Loan for HDB: Rate, LTV, Cash Down

Bank loans for HDB flats come from MAS-regulated lenders: DBS, OCBC, UOB, Maybank, Standard Chartered, HSBC and others. There's no income ceiling, but how much you can borrow is governed by TDSR (55%) and MSR (30%), both stress-tested at the MAS 4% floor rate.

You can compare current bank loan rates across packages, but it's the structure that matters more than the headline number:

• Fixed packages start from 1.40% p.a., typically 1.45%–1.65%, range 1.40%–2.00%, locked for 2–3 years.
• SORA-linked packages run at 3M SORA + 0.20%–0.75%, effective 1.55%–1.77% (3M SORA is 1.0201%).
• The board rate after lock-in sits at 3.50%–4.50%+ if you do nothing.
• Max LTV is 75%, with a 25% down payment.
• At least 5% has to be cash; the remaining 20% can come from CPF OA.

Side-by-Side: HDB Loan vs Bank Loan

Same flat, two ways to finance it: HDB at 2.6% with zero cash down, or a bank loan at 1.40%–1.65% that needs 5% cash and regular repricing.

Worked Example: S$500K Loan Over 25 Years

Take a S$500,000 loan over a 25-year tenure. Two scenarios: HDB at 2.6% held flat, and a bank loan at 1.55% fixed (assumed flat for the whole tenure, which is the best case). Treat the bank figure as the most you could realistically capture, not the typical result.

Scenario B assumes the borrower reprices or refinances at every lock-in expiry to maintain a sub-1.65% rate. If the loan reverts to a 4.0% board rate for any sustained period, the total cost can exceed Scenario A. Figures illustrative only.

The gap is roughly S$255 per month and ~S$77,000 in total interest. That's real money, but it comes with a condition. It only shows up if you reprice at every lock-in expiry. Let the loan drift onto a 4.0% board rate for two or three years and the whole saving is gone.

Worth being honest about this: the bank example assumes a flat 1.55% across all 25 years, which is the best case you'll ever get. Real outcomes land somewhere between Scenario A and Scenario B, and where you land depends on how disciplined you are about repricing. Reprice three times over 25 years and you'll come out close to the bank figure. Reprice once and forget about it, and you'll end up closer to HDB, or worse.

The Hidden Cost of a Bank Loan: Board Rate Drift

The low fixed rate is what gets you in the door. The board rate is what gets you later. Once your 2-year or 3-year lock-in ends, the package reverts to the bank’s board rate, commonly 3.50%–4.50% p.a. for legacy HDB packages. That sits well above the HDB concessionary rate.

Staying on top of it means repricing with the same bank or refinancing to a new lender every 2–3 years. Repricing is the cheaper option (often free, sometimes a small admin fee). Refinancing carries legal and valuation costs of roughly S$1,500–S$2,500 each time, but usually buys you a lower rate. Use the refinance savings calculator to size up the gap, and read when to refinance in Singapore for the timing. Already on the HDB loan and tempted by sub-1.5% bank rates? Have a look at whether you should refinance your HDB loan to a bank loan in 2026, including why it's a one-way move.

Who Should Pick the HDB Loan

• You're short on cash. Zero cash down can be the difference between buying now and waiting another two years.
• You want a loan you can set once and ignore. No repricing, no lock-in to keep track of, no board-rate surprise.
• You'd like to keep your options open. There's no early repayment penalty, and you can switch to a bank loan once if rates ever swing in its favour.
• You're buying a BTO and cash flow is tight. The first-time HDB buyer guide covers this.

Who Should Pick the Bank Loan

• Your income is above S$14,000/month, so the HDB loan isn't open to you anyway.
• You're sitting on a solid cash position, and the 5% cash component (S$25,000 on a S$500K flat) isn't a stretch.
• You'll actually reprice on schedule, every 2–3 years, without fail.
• You're not holding the flat for long. Selling or upgrading within 5–7 years lets you ride the fixed rate and exit before the board rate ever kicks in.
• You're buying an Executive Condominium, where HDB loans aren't available in the first place.

The One-Way Door: HDB to Bank, Never Back

You can refinance from an HDB loan to a bank loan once. You can't switch back. Once a flat has been on bank financing, HDB won't take it back into the concessionary scheme.

That's why I tell clients who qualify for both to start with the HDB loan. You get zero cash down and a stable rate from day one. If bank rates stay attractive and your equity grows, you can always move to a bank package later. The other direction simply isn't an option.

Affordability and CPF: Run the Numbers First

Before you choose, work out what's actually capping your loan size. For HDB buyers, MSR limits monthly housing payments to 30% of gross income. Bank loans pile the 55% TDSR and the MAS 4% stress test on top of that. Use the TDSR/MSR affordability calculator to see the maximum loan each route allows on your income.

How you use your CPF OA matters too. The HDB route lets you fund the whole down payment from OA, but it drains your OA faster. A bank loan leaves you more cash flexibility but asks for the 5% cash component upfront. The CPF OA guide for HDB buyers walks through that trade-off. If you might buy a second property later, your equity / cash-out loan options also hinge on which route you pick now.
