Choosing between an HDB housing loan and a bank loan is one of the biggest financial decisions buyers face when purchasing an HDB flat. While an HDB loan generally offers greater stability and flexibility, a bank loan may provide lower interest rates depending on market conditions.
Here are the main differences to consider.
1. Interest Rates
The HDB concessionary loan currently carries an interest rate of 2.6% per annum. It is pegged at 0.1 percentage point above the CPF Ordinary Account interest rate, providing borrowers with relatively predictable monthly repayments.
Bank loan interest rates vary between financial institutions and may change according to market conditions. Some packages offer attractive fixed rates for an initial period, while others are linked to benchmarks such as the Singapore Overnight Rate Average.
A bank loan may therefore be cheaper when market rates are low, but repayments could increase when the fixed-rate period ends or interest rates rise.
2. Downpayment Requirements

Both HDB and bank loans currently have a maximum Loan-to-Value limit of 75%, subject to the buyer’s financial circumstances and loan tenure. This means buyers may need to fund at least 25% of the flat’s price through cash, CPF savings or a combination of both.
For an HDB loan, the downpayment can generally be paid using CPF Ordinary Account savings, provided the buyer has sufficient funds.
For a bank loan, at least 5% of the purchase price must be paid in cash, while the remaining portion of the downpayment may be paid using CPF savings.
An HDB loan may therefore be more suitable for buyers who have limited cash available upfront.
3. Repayment Flexibility
HDB loans generally provide greater flexibility. Borrowers can make partial or full early repayments without being subject to a lock-in period or early repayment penalty.
Bank loans may come with lock-in periods, typically during the initial fixed-rate period. Selling the flat, refinancing the loan or making a large repayment during this period may result in additional charges.
Buyers considering a bank loan should review the package’s lock-in period, repricing options and penalty clauses carefully.
4. Eligibility and Loan Assessment

HDB loans are only available to buyers who meet HDB’s eligibility requirements. The approved loan amount will also depend on factors such as household income, age, existing financial commitments and the remaining lease of the flat.
Bank loans are not subject to HDB’s income ceiling for concessionary loans, but applicants must pass the bank’s credit assessment. Banks will examine factors including income stability, credit history and existing debt obligations.
Buyers should obtain an HDB Flat Eligibility letter and compare available bank loan offers before committing to a flat purchase.
5. Ability to Switch Loans
Buyers who initially take an HDB loan may later refinance to a bank loan, potentially benefiting from lower market rates.
However, once an HDB loan has been refinanced with a bank, the borrower generally cannot switch back to an HDB loan. Buyers should therefore consider whether the potential savings outweigh the loss of flexibility and repayment certainty.
Which Loan Is Better?
An HDB loan may be more suitable for first-time buyers, households with less cash available and those who prefer stable repayments without lock-in periods or early repayment penalties.
A bank loan may be more suitable for buyers with sufficient cash reserves who are comfortable monitoring interest rates and refinancing their loan when necessary.
The better option ultimately depends on the buyer’s available cash, financial stability, risk tolerance and expected holding period. Rather than focusing only on the initial interest rate, buyers should compare the total repayment cost and ensure that future instalments remain manageable if circumstances or market rates change.
