HDB Home Loan vs Bank Loan: 2026 Singapore Comparison

HDB at 2.6% p.a. is set-and-forget. Bank fixed from 1.40% p.a. is cheaper on paper, but only if you actively reprice. Here is the side-by-side for HDB flat buyers in 2026.

The Headline Trade-Off

Every HDB buyer faces one fork: take the HDB concessionary loan at 2.6% p.a., or take a bank loan from 1.40% p.a. The numbers favour the bank. The behaviour required does not.

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 after lock-in expires. To keep the savings, you must 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 held there since January 2008.

Eligibility is the gate. 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 must not own any private residential property, and you cannot have taken two prior HDB loans. The HFE Letter confirms whether you qualify before you commit.

• Max LTV: 80% — the highest available for HDB purchases
• Down payment: 20%, fully payable from CPF OA — zero cash
• No lock-in, no early repayment penalty
• MSR 30% applies; 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 is no income ceiling, but borrowing capacity 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 the structure is what matters:

• Fixed: from 1.40% p.a., typical 1.45%–1.65%; range 1.40%–2.00%; locked 2–3 years
• SORA-linked: 3M SORA + 0.20%–0.75%; effective 1.55%–1.77% (3M SORA = 1.0201%)
• Board rate (post-lock-in): 3.50%–4.50%+ if you do nothing
• Max LTV: 75%; down payment 25%
• Minimum 5% cash; remaining 20% from CPF OA

Side-by-Side: HDB Loan vs Bank Loan

Two paths for the same flat: HDB at 2.6% with zero cash down, or a bank loan at 1.40%–1.65% that requires 5% cash and active 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 as a best-case). The bank figure is the ceiling of what a borrower can capture, not the average outcome.

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 — meaningful, but conditional. It only materialises if the borrower actively reprices at every lock-in expiry. If the loan drifts onto a 4.0% board rate for two or three years, the entire saving is erased.

Worth noting: the bank loan example assumes a flat 1.55% rate across 25 years, which is the best case. Real outcomes sit somewhere between Scenario A and Scenario B depending on how disciplined the repricing is. A borrower who reprices three times across 25 years will land closer to the bank figure. A borrower who reprices once and forgets will land closer to HDB — or worse.

The Hidden Cost of a Bank Loan: Board Rate Drift

The fixed-rate sticker price is the bait. The board rate is the trap. 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 is well above the HDB concessionary rate.

Active management means repricing with the same bank or refinancing to a new lender every 2–3 years. Repricing is cheaper (often free, sometimes a small admin fee). Refinancing involves legal and valuation costs of roughly S$1,500–S$2,500 per event but typically secures a lower rate. Use the refinance savings calculator to size the gap, and read when to refinance in Singapore for timing.

Who Should Pick the HDB Loan

• Limited cash buffer. Zero cash down is the difference between buying now and waiting two years.
• You want a set-and-forget loan. No repricing, no lock-in to track, no board-rate risk.
• You may want flexibility later. No early repayment penalty; you can switch to a bank loan once if rates ever favour it.
• You are buying a BTO and cash-flow is tight. See the first-time HDB buyer guide.

Who Should Pick the Bank Loan

• Income exceeds S$14,000/month. You do not qualify for the HDB loan.
• Strong cash position. The 5% cash component (S$25,000 on a S$500K flat) is not a stretch.
• You will reprice on schedule. Every 2–3 years, without fail.
• Short holding period. Selling or upgrading within 5–7 years lets you capture the fixed rate without entering board-rate territory.
• You are buying an Executive Condominium. HDB loans are not available for ECs.

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

You can refinance from an HDB loan to a bank loan once. You cannot switch back. HDB will not re-admit a flat to the concessionary scheme after it has been on bank financing.

This makes the HDB loan the safer first move for buyers who qualify for both. You get zero cash down and rate stability now. If bank rates stay attractive and your equity grows, you can move to a bank package later. The reverse path does not exist.

Affordability and CPF: Run the Numbers First

Before choosing, check the binding constraint on your loan size. For HDB buyers, MSR caps monthly housing payments at 30% of gross income. Bank loans add the 55% TDSR and the MAS 4% stress test on top. Use the TDSR/MSR affordability calculator to see the maximum loan each route allows for your income.

CPF OA strategy matters too. The HDB route lets you fully fund the down payment from OA but burns OA faster. A bank loan preserves more cash flexibility but requires the 5% cash component upfront. The CPF OA guide for HDB buyers walks through the trade-off. If you are buying a second property later, the equity / cash-out loan options also depend on which route you take now.
