For most Singaporeans, buying an HDB flat means taking on a home loan that will last decades. One of the first decisions buyers face is whether to finance their flat with an HDB concessionary loan or a bank loan.

In 2025 and early 2026, Singapore bank home loan interest rates eased from the higher levels seen in previous years. Fixed-rate mortgage packages that were commonly quoted in the low 3% range in early 2025 have since been offered closer to the 1.4%–1.8% range in late 2025 into 2026, as benchmark rates softened and banks became more competitive.

This shift has prompted more buyers—including HDB buyers—to re-examine whether a bank loan could be worth considering alongside the historically stable HDB concessionary loan.

For starters, both options can be used to buy the same HDB flat, but they work very differently. Interest rates are structured differently. Upfront costs differ. So do eligibility rules, repayment flexibility, and how much you can comfortably borrow.

This guide breaks down how HDB loans and bank loans work in 2026, so you can understand the trade-offs clearly before deciding which path makes sense for you.

1. Why this choice matters for today’s HDB buyers

A home loan isn’t just about the interest rate you start with. It affects:

• how much cash or CPF you need upfront
• how predictable your monthly repayments are
• how flexible you are if your finances change
• whether you can switch loans later without penalties

In recent years, interest rates have moved more than many buyers were used to. At the same time, HDB affordability rules and loan limits have continued to shape how much buyers can borrow. That’s why understanding how each loan option works—beyond headline rates—matters more than ever.

2. The 2 main home loan options for HDB flats

What is an HDB concessionary loan?

An HDB concessionary loan is provided directly by the Housing & Development Board. It is available only to buyers who meet HDB’s eligibility criteria, including citizenship, income ceilings, and property ownership rules.

The interest rate for an HDB loan follows a fixed formula: it is pegged to the CPF Ordinary Account (OA) interest rate plus a small margin. Because CPF OA rates are relatively stable, HDB loan repayments tend to be predictable over time.

What is a bank home loan?

Bank home loans are offered by private financial institutions such as DBS, OCBC and UOB, among others. These loans are typically pegged to market benchmarks such as SORA (Singapore Overnight Rate Average), or offered at a fixed rate for an initial period before switching to a floating rate.

Bank loans give borrowers more exposure to market movements. When rates fall, repayments may become cheaper. When rates rise, repayments can increase. This variability is an important difference compared to HDB loans.

3. HDB loan vs bank loan—Key differences at a glance

This table isn’t about deciding which loan is “better”. It’s about understanding how the structure of each loan affects your finances.

Next, we’ll dive deeper into 4 differences between the 2 types of loans and explain how you should factor them in.

Both HDB loans and bank loans generally allow buyers to borrow up to 75% of the flat’s purchase price or valuation, whichever is lower. CPF OA can usually be used to cover the monthly instalments

That means buyers must fund the remaining 25% upfront using a combination of CPF OA savings and cash.

With an HDB loan, many buyers can cover most or all of this 25% using CPF OA, depending on how much they have accumulated. Cash is only required if CPF OA is insufficient

With a bank loan, buyers are required to pay at least 5% in cash, with the remaining portion of the downpayment funded by CPF OA or additional cash.

However, the 75% borrow limit is only one part of the equation.

Income-based limits: MSR and TDSR

Beyond the property-based cap, how much you can borrow is also constrained by affordability rules.

For HDB flats, the Mortgage Servicing Ratio (MSR) limits how much of your gross monthly income can go towards your home loan instalment.

For bank loans, lenders also assess the Total Debt Servicing Ratio (TDSR), which looks at all your debt obligations combined—including car loans, credit cards and other commitments—not just your mortgage.

In practical terms, this means:

• You may not qualify for the full 75% loan amount even if the property value allows it.
• A bank loan might look cheaper on paper, but your existing debts could reduce how much you’re allowed to borrow.

For some buyers, the LTV is the binding constraint. For others, it’s the income-based rules that determine their actual loan amount.
