Refinancing a home loan in Singapore means switching an existing mortgage to a new loan package — either with the same bank (repricing) or a different bank (refinancing) — typically to secure a lower interest rate or better loan terms.

Key Takeaways
- Refinancing usually becomes cost-effective once a borrower’s existing mortgage exits its lock-in period, since breaking a lock-in early typically triggers a penalty of around 1.5% of the outstanding loan amount.
- Switching to a different bank (refinancing) generally offers access to the most competitive market rates, while staying with the same bank (repricing) is usually faster and cheaper in legal/valuation fees but may not match the best available rate.
- Most banks offer subsidies covering legal and valuation fees for refinancing, but these subsidies often come with a claw-back clause if the loan is refinanced again within a set period, typically two to three years.
- For HDB flats, refinancing from an HDB loan to a bank loan is a one-way decision — once a borrower switches to a bank loan, they generally cannot switch back to an HDB loan for that flat.
- The Total Debt Servicing Ratio (TDSR) framework applies to refinancing applications in the same way it applies to new loans, meaning approval is not automatic even for borrowers who have serviced their current loan reliably.
What Is Refinancing a Home Loan?
In Singapore, home loan interest rates are typically structured with an attractive promotional rate for the first few years (often 2–3 years), after which the rate steps up — sometimes significantly — unless the borrower takes action. Refinancing is how borrowers avoid simply rolling onto a higher “reversion rate” or default rate once their initial lock-in period ends.
The term covers two related but distinct moves. “Repricing” means staying with the same bank but switching to a new rate package it currently offers — generally a simpler, cheaper process since the property does not need to be revalued and legal work is minimal. “Refinancing” (in the stricter sense) means moving the loan to a different bank entirely, which usually requires a fresh valuation and legal conveyancing, but often unlocks more competitive rates since borrowers can shop across the whole market rather than just their existing bank’s offers.
Because mortgage rates in Singapore are influenced by benchmarks such as the Singapore Overnight Rate Average (SORA), and packages are periodically repriced by banks to stay competitive, many financial advisers recommend borrowers review their home loan roughly every two to three years, timed around the end of their existing lock-in period.
How Does Refinancing Work in Singapore?
The refinancing process typically starts a few months before a borrower’s existing lock-in period ends, giving enough time to compare packages, apply, and complete legal work before the old rate expires and before any early-redemption penalty window closes.
| Step | What Happens |
|---|---|
| 1. Check lock-in status | Confirm when the current lock-in period ends to avoid early-redemption penalties, typically around 1.5% of the outstanding loan |
| 2. Compare packages | Shop across banks (refinancing) or request current offers from the existing bank (repricing) |
| 3. Apply and get approved | New bank assesses income, credit history and TDSR, similar to a fresh home loan application |
| 4. Valuation and legal work | Property is revalued (for refinancing) and legal conveyancing is arranged, often subsidised by the new bank |
| 5. Loan is switched over | New bank disburses funds to redeem the old loan; borrower begins repaying under the new package |
Borrowers should also factor in the “claw-back” clauses attached to many banks’ legal/valuation subsidies — refinancing again too soon after receiving a subsidy can trigger a requirement to repay that subsidy, which should be weighed against the savings from switching.
Refinancing Example
Mr and Mrs Koh took a S$700,000 bank loan for their condominium three years ago, locked in at a promotional rate. As their three-year lock-in ends, their rate is set to revert to a much higher floating rate unless they act. They begin comparing packages four months before the lock-in expires.
They find that refinancing with a different bank offers a meaningfully lower rate than their current bank’s best repricing offer, even after accounting for the new bank’s legal and valuation subsidy conditions. They proceed with the refinance, completing the switch just as their old lock-in period ends — avoiding both the early-redemption penalty (since they timed it correctly) and the higher reversion rate they would otherwise have faced.
Had they refinanced a year earlier, while still locked in, they would have incurred a prepayment penalty of roughly 1.5% of their outstanding loan — on a balance of around S$620,000 at that point, a penalty of over S$9,000 — which would have eaten significantly into the interest savings from switching.
Advantages of Refinancing
- Lower interest costs. Securing a more competitive rate after a lock-in period ends can meaningfully reduce total interest paid over the remaining loan tenure.
- Avoids the reversion rate trap. Refinancing before a loan rolls onto a bank’s default floating rate prevents a sudden jump in monthly instalments.
- Flexibility to change loan features. Refinancing can be an opportunity to switch from a fixed to floating rate package (or vice versa), adjust the loan tenure, or consolidate other debt.
- Subsidised costs are common. Many banks offer to cover legal and valuation fees for refinancing, reducing the upfront cost of switching.
- Encourages active loan management. Regularly reviewing and refinancing a mortgage keeps a borrower engaged with market rates rather than passively accepting whatever their current bank charges.
Risks and Limitations
- Early-redemption penalties during lock-in. Refinancing before the lock-in period ends typically triggers a penalty, commonly around 1.5% of the outstanding loan amount.
- Claw-back of subsidies. Legal and valuation subsidies from a previous refinance often come with a claw-back clause if the loan is switched again within a set period.
- TDSR approval is not guaranteed. Even reliable borrowers must pass the bank’s Total Debt Servicing Ratio assessment again, which can be affected by changes in income, other debts, or tightened lending criteria since the original loan was taken.
- HDB-to-bank-loan switches are generally irreversible. HDB flat owners who refinance from an HDB loan to a bank loan typically cannot switch back to an HDB loan later for that flat.
- Market timing uncertainty. Interest rate benchmarks like SORA fluctuate, so a rate that looks attractive today may not remain the most competitive option for the full new lock-in period.
Repricing vs Refinancing
| Feature | Repricing (Same Bank) | Refinancing (Different Bank) |
|---|---|---|
| Process complexity | Simpler, usually no revaluation needed | More involved, usually requires fresh valuation and legal work |
| Typical cost | Lower, sometimes minimal admin fee | Legal/valuation fees, often subsidised by the new bank |
| Rate competitiveness | Limited to current bank’s offers | Can access the broader market’s best available rates |
| Processing time | Generally faster | Generally slower, several weeks for valuation and legal work |
| Best suited for | Borrowers satisfied with their bank wanting a quick rate update | Borrowers prioritising the lowest available rate across the market |

The Bottom Line
For Singapore homeowners, refinancing is the primary tool for avoiding a sharp jump onto a bank’s default reversion rate once a promotional lock-in period ends. Timed correctly — around the end of the lock-in and with subsidy claw-back terms factored in — it can meaningfully reduce interest costs over a loan’s remaining tenure, though the savings should always be weighed against any early-redemption penalties and the time cost of switching.
Frequently Asked Questions
What does it mean to refinance a home loan in Singapore?
Refinancing means switching an existing mortgage to a new loan package, either with the same bank (repricing) or a different bank (refinancing), typically to secure a better interest rate once the original lock-in period ends.
When is the best time to refinance a home loan?
Most borrowers time their refinancing around the end of their existing lock-in period, since breaking a lock-in early typically triggers a prepayment penalty of roughly 1.5% of the outstanding loan.
What is the difference between repricing and refinancing?
Repricing means switching to a new rate package with the same bank, which is usually faster and cheaper, while refinancing means moving the loan to a different bank entirely, which can unlock more competitive rates but requires fresh valuation and legal work.
Can I refinance my HDB loan to a bank loan?
Yes, HDB flat owners can refinance from an HDB loan to a bank loan, but this is generally a one-way decision — once switched to a bank loan, the flat typically cannot revert to an HDB loan afterward.
Does refinancing require income reassessment?
Yes, banks apply the Total Debt Servicing Ratio (TDSR) framework to refinancing applications just as they do for new loans, so approval depends on the borrower’s current income and debt obligations, not just their repayment history.
Are there fees involved in refinancing a home loan?
Refinancing typically involves legal and valuation fees, though many banks offer subsidies to cover these costs — often with a claw-back clause if the loan is refinanced again within a set period.
