HDB loan vs bank loan in Singapore — which should you choose?
When buying an HDB flat in Singapore, you choose between the HDB concessionary loan (2.6% fixed rate, up to 80% LTV, from HDB directly) and a bank mortgage (typically lower rates, up to 75% LTV, from any of Singapore's major banks). The right choice depends on your financial position, risk tolerance, and how long you plan to hold the property. This guide compares both honestly.

HDB concessionary loan
The HDB concessionary loan is a mortgage offered directly by the Housing Development Board to eligible buyers of HDB flats. It is not offered by banks — you apply through the HDB directly at the point of purchase.
The rate is pegged at CPF OA rate + 0.1%. The CPF OA rate has been at 2.5% since 1999, making the HDB loan rate 2.6%. It is reviewed quarterly but has been stable for decades. This stability is the HDB loan's core selling point.
HDB loan advantages
- ✓No cash downpayment required — full CPF OA allowed
- ✓No lock-in period or early repayment penalty
- ✓Rate certainty — not exposed to market rate spikes
- ✓Easier approval — HDB is more lenient than banks
- ✓Can switch to a bank loan later if rates improve
HDB loan disadvantages
- ⚠2.6% is currently higher than the best bank fixed rates
- ⚠Only for HDB flats — not ECs or private property
- ⚠Income ceiling applies ($14,000/month household)
- ⚠Once you switch to bank loan, cannot switch back
- ⚠Lower LTV cap (80%) locks in equity but limits purchase power
Bank mortgage for HDB flats
Banks offer mortgages for HDB flats with two main pricing structures: SORA-pegged (floating) packages and fixed-rate packages. All bank loans for HDB flats are subject to the same TDSR (55%) and MSR (30%) limits as HDB loans.
SORA-pegged (floating rate)
3-month compounded SORA + spread (currently ~3.0–3.8% p.a.)
Pros
Rate falls when SORA drops; no lock-in after initial period
Cons
Rate rises when SORA rises; monthly repayment can change
Best for
Buyers expecting rates to fall, or with tolerance for variability
Fixed rate
Fixed for 2–5 years (currently ~2.8–3.5% p.a.), then converts to SORA
Pros
Certainty for the fixed period; rates currently competitive vs HDB loan
Cons
Lock-in period with early repayment penalty (typically 1.5%); rate uncertainty after fixed period
Best for
Buyers wanting certainty for 2–5 years and comfortable refinancing thereafter

LTV and downpayment: the most important difference
The Loan-to-Value (LTV) ratio determines how much the bank or HDB will lend relative to the flat's value. For most buyers, the downpayment cash requirement is the deciding factor.
HDB loan
Example: $500,000 flat → borrow $400,000, pay $100,000 from CPF OA, zero cash needed.
Bank loan
Example: $500,000 flat → borrow $375,000, pay $25,000 cash + $100,000 CPF OA.
When to choose each option
Choose HDB loan if:
You have limited cash savings
HDB loan needs no cash downpayment — ideal if your savings are mostly in CPF.
You value certainty over rate
If a variable mortgage would cause financial stress, 2.6% fixed is worth the premium.
You plan to sell within 5 years
No lock-in means you can sell without penalty. Bank loan lock-ins can cost 1.5% of outstanding loan on early exit.
Your income is near the ceiling
HDB is more lenient on affordability assessment. Banks apply TDSR and MSR strictly.
You want optionality
You can always refinance to a bank loan later. You cannot return to HDB loan once you switch.
Choose bank loan if:
Bank fixed rates are significantly lower
When fixed rates at 2.8–3.0% are available, the interest saving over a 25-year loan can be substantial versus the HDB's 2.6%.
You have adequate cash for 5% downpayment
If cash is not a constraint, the 5% cash requirement for bank loans is manageable and opens lower interest rates.
You are not a Singapore citizen
HDB concessionary loans are only available to SC buyers. PRs and foreigners must use bank mortgages.
You plan to rent out rooms
Bank loans are more flexible for buyers with complex rental arrangements or those monetising their property.
You want a 30-year tenure
Bank loans can offer up to 30-year tenures for eligible borrowers. HDB loans are capped at the remaining lease or 25 years, whichever is lower.
Frequently asked questions
What is the HDB concessionary loan interest rate?
The HDB concessionary loan interest rate is pegged at 0.1% above the CPF Ordinary Account (OA) rate. The CPF OA rate is currently 2.5% per annum, making the HDB loan rate 2.6% per annum. This rate is guaranteed by the government and does not fluctuate with market rates, providing certainty for borrowers.
Who is eligible for an HDB concessionary loan?
To qualify for an HDB concessionary loan: (1) At least one buyer must be a Singapore citizen. (2) Combined household income must not exceed $14,000 per month (or $21,000 for extended families, $7,000 for singles buying under certain schemes). (3) You must not own any private residential property at the time of application. (4) You must not have taken more than two HDB concessionary loans previously. (5) The property must be an HDB flat (not EC or private).
What is the maximum LTV for HDB vs bank loans?
HDB concessionary loan: up to 80% LTV (you need a minimum 20% downpayment, which can be paid fully from CPF OA). Bank loan: up to 75% LTV (you need a minimum 25% downpayment — 5% must be in cash, the remaining 20% can come from CPF OA). This means bank loans require a higher cash outlay at purchase.
Can I switch from HDB loan to bank loan after purchase?
Yes — you can refinance from HDB loan to a bank loan at any time, as long as your outstanding loan meets the bank's minimum. Banks typically require a minimum of $100,000–$200,000 outstanding. There is no penalty from HDB for switching. However, once you refinance to a bank loan, you cannot switch back to the HDB concessionary loan.
Is HDB loan or bank loan better?
There is no universal answer — it depends on your risk tolerance, cash position, and timeline. HDB loan is better if: you want rate certainty, have limited cash for downpayment, or plan to sell within 5 years without a longer lock-in. Bank loan is better if: interest rates are significantly lower than HDB's 2.6%, you are financially stable enough to manage rate changes, and you want more flexibility in refinancing. The best decision requires comparing actual bank offers against the HDB rate at your point of purchase.
What is the TDSR limit for HDB and bank loans?
The Total Debt Servicing Ratio (TDSR) of 55% applies to both HDB loans and bank loans in Singapore. This means your total monthly debt obligations (including the mortgage, car loans, credit card debt, and other loans) cannot exceed 55% of your gross monthly income. For HDB flats specifically, there is also a Mortgage Servicing Ratio (MSR) limit of 30% — meaning your monthly mortgage payment cannot exceed 30% of your gross income.
Should I use CPF or cash for the downpayment?
For HDB loans: the full 20% downpayment can come from CPF OA — no cash is required. For bank loans: 5% of the purchase price must be in cash; the remaining 20% can come from CPF OA. Using CPF preserves your cash, but CPF funds used for housing earn a notional return that must be refunded on sale. Whether cash or CPF is better depends on your investment alternatives for that cash — a separate calculation from the HDB vs bank loan decision.
