HDB Loan vs Bank Loan for a Resale Flat

An HDB loan and a bank loan can each finance up to 75% of a resale flat under qualifying conditions. The difference lies in cash, interest-rate risk and flexibility. A bank loan needs at least 5% cash, while an eligible HDB borrower can use CPF Ordinary Account (OA) savings for the downpayment.

The HDB concessionary rate is 2.6% a year for 1 July to 30 September 2026. Bank packages can start lower or higher and change with the package terms.

Compare the two loans on the same flat

Feature	HDB housing loan	Bank housing loan
Maximum LTV under qualifying conditions	Up to 75%	Up to 75%
Minimum cash downpayment	No fixed 5% cash requirement; eligible CPF may be used	At least 5% of lower of price or valuation
Interest	Concessionary rate, reviewed quarterly	Fixed-period or floating package
Lock-in	No lock-in	Common in mortgage packages
Early repayment	No HDB penalty	Penalty may apply during lock-in
Refinancing	Can move to a bank	Cannot move back to HDB for that flat
Loan tenure	Up to 25 years, subject to age and lease limits	Subject to bank and regulatory limits
Approval route	HFE letter	HFE letter plus bank approval and Letter of Offer

LTV is the loan-to-value limit. HDB applies it to the lower of the resale price or value of the flat. A bank also uses its valuation and credit assessment. Up to 75% does not mean either lender must approve 75%.

The HFE letter tells you whether you qualify for an HDB loan and the assessed amount. Our HFE letter guide covers the waiting time, documents and nine-month validity.

The cash difference appears at the downpayment

Assume a household buys a $700,000 resale flat, HDB values it at $700,000 and the lender approves a 75% loan.

Item	HDB loan	Bank loan
Purchase price	$700,000	$700,000
75% loan	$525,000	$525,000
25% downpayment	$175,000	$175,000
Mandatory cash within downpayment	No fixed 5% minimum	At least $35,000
Remaining downpayment	Eligible CPF or cash	$140,000 eligible CPF or cash

Both buyers still need cash for the option fee and option exercise fee, which can total up to $5,000. Any Cash Over Valuation also needs cash.

If the flat’s value comes in at $680,000, the $20,000 price difference sits outside the valuation base. The lender and CPF do not cover that gap. Add it to the cash target before exercising the Option to Purchase (OTP).

The HDB resale buyer-fees guide covers BSD, legal work and smaller transaction charges.

HDB gives a stable rate and repayment flexibility

HDB pegs its concessionary housing-loan rate at 0.1 percentage point above the CPF OA rate. The rate is 2.6% a year for the quarter from 1 July to 30 September 2026.

HDB does not impose a mortgage-package lock-in or an early repayment penalty. A household receiving a bonus can make a partial capital repayment without waiting for a lock-in to end. Check the CPF and retirement effect before using OA savings for a large prepayment.

HDB still conducts a credit assessment. It considers age, income, job stability, existing commitments, repayment history and monthly cash savings. The shortest applicable limit among the loan tenure, applicant age and remaining lease can reduce the loan.

For a flat whose remaining lease does not cover the youngest buyer to age 95, HDB prorates the LTV limit. CPF housing usage can also fall. Older flats need a lease-specific calculation before price negotiation.

Bank packages trade certainty for choice

Banks offer fixed-rate periods and floating packages, often linked to the Singapore Overnight Rate Average (SORA) or another stated benchmark. A fixed period does not fix the rate for the full mortgage. The package can move to a different rate after the fixed or promotional period.

Compare these terms in the Letter of Offer:

• rate during the lock-in and rate after it
• lock-in length
• early redemption and partial repayment penalties
• legal subsidy and its clawback period
• number of free repricing or conversion options
• cancellation fee on the undisbursed loan

A small rate gap can save money, but a planned sale or lump-sum repayment during lock-in can remove that saving. Ask each bank for the monthly instalment at the offered rate and at a higher rate.

The bank also requires a private solicitor for the mortgage work. Include the legal quote and any subsidy clawback when comparing loan costs.

Compare monthly payments with one loan amount

Use the same balance and tenure so the rate effect remains visible. For a $525,000 loan over 25 years:

Interest rate	Approximate monthly payment
2.5%	$2,355
2.6%	$2,382
3.0%	$2,490
4.0%	$2,771

These are standard amortising-loan illustrations. They exclude insurance, service and conservancy charges, property tax and household debts. Your lender sets the actual instalment and repayment method.

The Mortgage Servicing Ratio (MSR) caps monthly instalments for loans used to buy HDB flats at 30% of gross monthly income. Bank borrowers also face the Total Debt Servicing Ratio, which counts total monthly debt commitments.

Our TDSR and MSR guide explains both tests. Choose a mortgage that fits household spending below the regulatory ceiling.

The loan choice changes the resale timeline

An HDB-loan buyer needs a valid HFE letter when the seller grants the OTP.

A bank-loan buyer needs:

1. A valid HFE letter before the seller grants the OTP.
2. An In-Principle Approval before settling the price.
3. A valuation acceptable to the bank.
4. A valid Letter of Offer before exercising the OTP.
5. An accepted bank loan when submitting the resale application.

The standard HDB option period is 21 calendar days. A buyer who starts bank comparisons after receiving the OTP gives the valuer, bank and lawyer little room for delay.

Submit the Request for Value by the next working day after the Option date when required. The HDB resale timeline puts these deadlines in order.

CPF use has different practical effects

An eligible HDB borrower may use OA savings for the full 25% downpayment, subject to the flat’s value, remaining lease and CPF usage rules. HDB may allow each buyer to retain up to $20,000 in OA rather than using the full balance.

A bank borrower must first pay at least 5% of the lower of price or valuation in cash. Eligible OA savings or cash can cover the rest of the downpayment.

Using more CPF reduces cash outlay but increases the principal and accrued interest that must return to OA when the flat is sold. Keep enough OA and cash for interruptions in income, especially when a bank package can reprice.

Our CPF property guide explains housing limits and the sale refund.

Choose from your cash flow and likely exit

An HDB loan tends to suit a buyer who:

• needs to preserve cash for the purchase and renovation
• values a known interest mechanism and no lock-in
• expects to make partial repayments

A bank loan may suit a buyer who:

• can fund the mandatory cash downpayment
• accepts rate changes after the fixed or promotional period
• has compared the lock-in with the likely sale and refinancing date

Get both sets of numbers where eligibility allows. Compare the downpayment, five-year interest cost, legal fees and cost of an early sale. Once a bank loan finances the flat, you cannot switch that mortgage to HDB.
