HDB Loan vs Bank Loan: Which Should You Choose When Buying an HDB Flat?
HDB loans and bank loans both let you finance an HDB flat, but they work differently in interest rate, down payment, and flexibility. The right choice depends on your risk tolerance & cash position.

When you buy an HDB flat, you have two financing options: an HDB housing loan or a bank loan. Many buyers default to one without properly comparing both. The difference can run to tens of thousands of dollars over the life of the loan.
Here's a clear breakdown.
HDB Housing Loan
Interest rate: Pegged at 0.1% above the CPF Ordinary Account (OA) rate, currently 2.6% per annum. This rate has been stable for years and is reviewed quarterly.
Down payment: 20% of the purchase price or valuation (whichever is lower). This can be paid entirely using CPF, no cash required if your OA balance is sufficient.
Loan-to-Value (LTV): Up to 80% of valuation or purchase price.
Eligibility: At least one buyer must be a Singapore Citizen. Income ceiling and other HDB eligibility criteria apply.
Flexibility: You can make partial capital repayments or pay off the loan fully at any time without penalty.
Bank Loan
Interest rate: Linked to SORA (Singapore Overnight Rate Average) or fixed-rate packages. Rates currently range from approximately 2.8% to 3.5% per annum depending on the package. Fixed-rate periods typically last 2 to 3 years before floating.
Down payment: 25% of the purchase price for the first property, with a minimum 5% in cash.
Loan-to-Value (LTV): Up to 75%.
Eligibility: Available to all eligible buyers, including PRs. Subject to TDSR limits.
Flexibility: Early repayment penalties typically apply during the lock-in period (usually 2 to 3 years). After that, you can repay, refinance, or switch packages freely.
The Key Trade-Offs
Stability vs potential savings. HDB loans offer a predictable rate that has sat at 2.6% for years. Bank loans can be cheaper when fixed rates are low, but they reset after the lock-in period and introduce rate risk. In a rising rate environment, a bank loan that looked attractive at 2.2% in 2020 repriced to 3.5%+ by 2023.
Cash requirement. HDB loans allow the full down payment in CPF. Bank loans require at least 5% in cash on top of the CPF component. For buyers with limited cash savings, this is a meaningful difference.
Switching. You can move from an HDB loan to a bank loan later if rates become attractive. The reverse is not allowed, once you've taken a bank loan on an HDB flat, you cannot switch to an HDB loan.
Which Should You Choose?
For buyers who prioritise stability and have limited cash, the HDB loan is often the simpler, lower-risk choice. The rate is higher than the best bank rates in a low-rate environment, but the certainty and flexibility outweigh the marginal cost for most first-time HDB buyers.
For buyers with stronger cash reserves, a longer investment horizon, and comfort with rate fluctuations, a bank loan during a low fixed-rate window can result in meaningful interest savings over the loan tenure.
The decision also affects how you use CPF, something that has downstream implications when you sell. Worth modelling both scenarios before you commit.

Frequently Asked Questions
Can I switch from an HDB loan to a bank loan later?
Yes. You can refinance from an HDB housing loan to a bank loan at any time, subject to meeting the bank's eligibility criteria and TDSR limits. The reverse, switching from a bank loan back to an HDB loan, is not permitted.
Is the HDB loan interest rate fixed?
The HDB loan rate is pegged at 0.1% above the CPF OA interest rate (currently 2.5% OA rate = 2.6% HDB loan rate). It is reviewed quarterly and has been stable at 2.6% for many years, though it is technically variable.
What is the minimum cash down payment for a bank loan on an HDB flat?
For a first residential property, the minimum down payment is 25%, with at least 5% paid in cash. The remaining 20% can be funded using CPF OA savings.
Can PRs take an HDB loan?
No. HDB housing loans are only available if at least one buyer is a Singapore Citizen. PRs must use a bank loan to finance an HDB resale purchase.
What happens to my bank loan during the lock-in period?
Most bank loan packages have a lock-in period of 2 to 3 years during which early repayment or full redemption incurs a penalty (typically 1.5% of the outstanding loan). After the lock-in period, you can repay, refinance, or switch packages freely.
Not Sure Which Loan Structure Suits You?
Choosing between HDB and bank financing has long-term implications, on your CPF usage, your cash position, and your eventual sale proceeds. This is one of the decisions worth getting right early.
