A bank loan is not automatically better than an HDB loan because its starting rate is lower. Compare the actual approved amount, total borrowing cost, cash commitments and ability to absorb changes. This guide is for HDB homeowners comparing financing routes, not a live bank-rate table.
What changes when you choose a bank loan?
MoneySense explains that the HDB concessionary rate is pegged at 0.1 percentage point above the CPF Ordinary Account rate and can change with it. Bank packages can be fixed for an initial period or variable; a fixed introductory period is not a fixed rate for the entire mortgage.[3]
The switch also changes your future options: an existing bank loan on an HDB flat cannot be refinanced into an HDB loan. Treat moving from HDB financing to bank financing as a decision with that limitation, not a reversible trial.[3]
For a purchase: start with the loan assessment, not a downpayment slogan
MoneySense states that an HDB loan can be up to 75% of the lower of the purchase price and valuation, subject to assessment. Its bank-loan table distinguishes different outstanding-loan and tenure situations; in the 75% LTV case with no outstanding housing loan, the minimum cash downpayment is 5%. Those are not universal terms for every borrower.[5]
For an HDB resale purchase, COV is cash-only. A large CPF balance therefore does not by itself establish that the transaction is affordable.[1] Our COV cash-budget guide separates the price balance from cash-only exposure.
Do not transplant a purchase downpayment percentage onto a refinancing decision for a home you already own. For refinancing, ask the new lender to specify the approved replacement loan, any funding shortfall and all costs of the switch. Keep those figures separate from the cost of buying another property.
For refinancing: compare the same balance and remaining term
Ask each lender to quote against the same outstanding balance and remaining tenure. A lower instalment achieved by extending the loan is not the same as an interest saving. MoneySense warns that a longer tenure can lower monthly payments while increasing total interest.[5]
Use a comparison sheet with a column for staying put, repricing with your existing bank if applicable, and refinancing with another lender. MoneySense distinguishes repricing from refinancing and recommends reviewing charges, repayment schedules and lock-in conditions before switching.[3]
- Loan balance and end date: keep both constant for the first comparison.
- Rate path: record the introductory period, what follows it, and how a variable rate is determined.
- Payments: ask for monthly payments and interest over the comparison period, plus the remaining balance at the end.
- One-off costs: obtain the legal, valuation, conversion and other charges that actually apply; do not use a generic fee assumption as a quote.
- Exit conditions: ask about lock-in charges, subsidy clawbacks, notice requirements and planned sale or early repayment.
- Liquidity: record the cash needed to complete the switch and retain the household buffer you choose.
MoneySense says the bank’s property loan fact sheet sets out key features including tenure, repayment information, lock-in period and penalty fees. Ask the lender to explain it instead of relying on an advertisement.[3]
A simple break-even screen — not a savings forecast
Hypothetical screen: suppose verified switching costs total S$2,000 and a like-for-like comparison initially shows S$100 lower monthly cash payments. S$2,000 ÷ S$100 = 20 months. That is a simple cash-flow recovery period only; it is not proof of a lower total financing cost.
If the difference falls to S$50 a month, recovery takes 40 months; at S$0 there is no recovery through lower payments. If you expect to sell or refinance again earlier, or charges change, the initial headline saving may be irrelevant. These are invented round-number inputs for arithmetic, not current lender offers or expected outcomes.
Compare remaining balances as well as payments. Fees, changing rates, different repayment schedules, CPF usage and the time value of money are excluded from this shortcut. Obtain a full written comparison before deciding.
Questions worth taking to your lender
- What rate applies after the introductory period?
- What happens to the payment under a higher-rate scenario?
- What exact charges apply if I sell, make a partial repayment or switch during the lock-in?
- Are benefits conditional on another product or a minimum loan size?
- What will I owe at the end of the comparison period, not just each month?
If payments are becoming difficult, MoneySense advises approaching HDB or your bank promptly to discuss options.[3] A new mortgage is not a substitute for resolving an unaffordable household budget.
Your next step: test your own numbers
Use the ungated mortgage calculator with a rate and tenure you choose, then compare the result with your lender’s schedule. For the broader decision, read our home-buying preparation guide. No rate forecast, approval or savings guarantee is implied.
