Should I choose an HDB loan or bank loan?

HDB loans are simpler with lower rates (typically 2.6% current), no MSR cap (only 30% applies), and no annual review. Bank loans have flexibility to switch lenders mid term and may offer lower rates at specific points. For HDB properties, HDB loans are usually cheaper; for private properties, bank loans are mandatory. Get an AIP from both to compare true costs.

What is TDSR and how does it affect my loan?

Total Debt Servicing Ratio (TDSR) is your maximum monthly debt payments divided by gross monthly income. The ceiling is 55% for most borrowers. If you earn $5,000/month, your maximum monthly debt is $2,750. This includes car loans, credit card minimums, and the new mortgage. Plan conservatively: lenders often approve you to the limit, but affordability is different from qualification.

What is the difference between fixed and floating rate mortgages?

Fixed rate mortgages lock your interest rate for a set term (typically 3 to 5 years), then adjust. Floating (variable) rates move with market rates immediately. Fixed rates protect you if interest rates rise but often start higher than floating rates. During periods of rising rates, fixed rates become more valuable; during falling rates, floating rates save money. Choose based on your risk tolerance and interest rate outlook.

Can I pay off my home loan early?

Yes. Most mortgages allow early repayment with no penalty. Some bank loans impose an early repayment fee in the first 1 to 3 years; check your contract. Early repayment reduces total interest paid significantly. However, always maintain an emergency fund of at least 6 months of expenses before aggressively paying down your mortgage.

How much can I borrow for an HDB vs private property?

HDB loans cap at 80% of the property value or your HDB loan ceiling (set by HDB), whichever is lower. Banks cap private property loans at 75% to 80% of valuation. Your actual borrowing capacity depends on your income, existing debt, and the property's valuation. Get an Approval in Principle (AIP) from your bank to confirm the exact quantum before property hunting.

Home loan Singapore: how to choose the right mortgage

By Winfred Quek · 10 minute read · Last reviewed Aug 2026

Quick answer: Most HDB buyers should choose HDB loans over bank loans because of lower rates (currently 2.6%), simpler terms, and no TDSR cap (only 30% MSR applies). Bank loans offer flexibility and may be cheaper at specific rate points. Private property buyers have no choice—only bank loans available. Always get an Approval in Principle (AIP) from both HDB and a bank before committing to a property.

Interest rates and lending rules change. Verify current rates with your bank and HDB before applying.

Key Takeaways

HDB loans are typically 0.3% to 0.5% cheaper than bank loans and have no annual rate reviews.
TDSR (Total Debt Servicing Ratio) caps your maximum debt at 55% of gross income; MSR caps HDB loan repayments at 30%.
Fixed rate mortgages lock your rate for 3 to 5 years, then adjust. Floating rates move with market immediately.
Early repayment is allowed on most mortgages with no penalty; check your contract for the first 1 to 3 years.
Loan quantum is limited by your income, existing debt, and property valuation—not just your qualification.

Choosing a mortgage is not just about interest rates. It is about affordability, flexibility, and ensuring the monthly payment fits your actual budget, not just the maximum the bank approves. Most borrowers can afford the maximum TDSR allows; fewer can afford it comfortably while maintaining savings and emergency reserves.

HDB loan vs bank loan: which should you choose?

If you are buying an HDB flat, you have a choice between an HDB loan and a bank loan. Private property buyers only have access to bank loans. The comparison is straightforward.

Factor	HDB Loan	Bank Loan
Current interest rate	2.6% (fixed, no annual review)	3.0%–3.2% (variable; reviews annually)
Loan quantum	Up to 80% of flat price or HDB ceiling	Up to 75%–80% of bank valuation
TDSR / MSR cap	MSR 30% (no TDSR cap)	TDSR 55%
Early repayment	No penalty	Penalty in years 1–3 (typically 2–3%)
Flexibility	Fixed terms, no refinancing mid term	Can refinance or switch lenders
Approval speed	2–3 weeks after OTP	1–2 weeks

Understanding TDSR and MSR: what do they mean for your loan?

According to MAS, TDSR (Total Debt Servicing Ratio) is the single most important constraint on your borrowing capacity.

TDSR 55% ceiling

Your total monthly debt payments divided by your gross monthly income cannot exceed 55%. This includes your new mortgage, car loans, personal loans, credit card minimums, and any other debt. If you earn $5,000/month, your maximum total monthly debt is $2,750. If you already have a $500/month car loan, your mortgage can only be $2,250/month.

MSR 30% cap for HDB loans only

For HDB buyers, an additional cap applies: your monthly mortgage payment cannot exceed 30% of gross income, regardless of other debt. This is more generous than TDSR and means HDB borrowers can typically afford more house than private buyers on the same income.

Example: you earn $6,000/month with a $400/month car loan. Under TDSR, you can borrow enough for a $2,900/month mortgage ($6,000 × 55% = $3,300 minus $400 car loan). Under MSR, you can borrow enough for a $1,800/month mortgage ($6,000 × 30%). HDB MSR is the binding constraint here.

Fixed vs floating rate: which is better?

The choice between fixed and floating rates depends on your risk tolerance and interest rate outlook.

Fixed rates (typically 3 to 5 years)

Your rate is locked for a set term, then adjusts to a floating rate. Fixed rates protect you if market rates rise sharply. However, fixed rates are often 0.2% to 0.5% higher than starting floating rates, so you pay a premium for certainty. When rates are rising, this premium becomes a bargain; when rates fall, you regret locking in.

Floating rates (variable)

Your rate moves with market rates immediately, typically tracked to a bank's base rate or SIBOR (Singapore Interbank Offered Rate). Floating rates start lower than fixed rates. When rates fall, you save money immediately; when rates rise, your payment climbs. Floating rates suit borrowers who can absorb rate increases and have high risk tolerance.

During 2022 to 2024, floating rates rose sharply and caught many borrowers off guard with monthly payment increases of $200 to $500. Fixed rates protected borrowers during this period. Choosing requires honest assessment of whether you can handle a 1% to 2% rate increase without financial strain.

How much can you borrow?

Your loan quantum is constrained by three factors: income, existing debt, and property valuation. Banks will approve you to the regulatory maximum, but that does not mean you should borrow that much.

Step 1: Calculate your TDSR limit. Gross monthly income × 55% minus existing monthly debt obligations = maximum new mortgage payment.

Step 2: Calculate your MSR limit (HDB only). Gross monthly income × 30% = maximum HDB mortgage payment. The MSR is often the binding constraint.

Step 3: Get a bank valuation. Banks lend up to 75%–80% of the property's valuation, not the purchase price. If you negotiate a purchase price of $600,000 but the bank values it at $580,000, your maximum loan is 80% × $580,000 = $464,000, not $480,000.

Step 4: Choose your loan quantum conservatively. Just because you can borrow $450,000 does not mean you should. Budget for interest rate increases, job loss, and unexpected expenses. A $350,000 loan with a 20% downpayment offers more financial breathing room than a $450,000 loan stretched to the limit.

Frequently asked questions

Can I switch from HDB loan to bank loan mid term?

Not directly. If you wish to switch, you must refinance the entire loan with a bank. This involves legal fees, valuation, and switching costs. It is rarely worth it unless you are getting a substantially better rate (typically 0.5% or more). Plan your loan choice upfront, not as an afterthought.

What happens if interest rates spike after I lock in a floating rate?

Your monthly payment goes up. If you borrowed $400,000 at 3% (monthly payment $1,686), a 1% rate increase to 4% raises your payment to $1,909, an extra $223/month or $2,676/year. This is why lenders stress test you at a higher rate (typically 3% above your approved rate) to ensure you can handle rate increases.

Should I make a larger downpayment to borrow less?

It depends. If you have cash and receive low or no interest on it, a larger downpayment makes sense. However, if you need that cash for renovations, emergencies, or investments, borrow more and keep the cash. CPF Ordinary Account contributions grow at 2.5% per year, which is lower than mortgage interest, so borrowing is often better than depleting your CPF early. Always keep 6 months of emergency savings in liquid cash.

Do I have to disclose all debts to the bank?

Yes. The bank will pull your credit bureau report, which lists all loans, credit card limits, and repayment history. Hiding debt is fraud. Be honest about what you owe; it directly impacts your loan quantum and the bank's decision.
