Singapore Mortgage Refinancing in a Nutshell
Singapore mortgage refinancing means moving your home loan from one bank to another to get a lower interest rate, usually without buying or selling the property. The goal is simple: cut your monthly repayment and save money over the remaining loan tenure. For most borrowers, a well-timed refinance can lower your rate by 0.5 to 1.0 percentage point, which on a 25-year loan of $500,000 can translate into tens of thousands of dollars in interest savings.
Many homeowners in Singapore lock into a fixed or floating rate for a period of two to three years. When that lock-in period ends, the bank will often raise the rate to its standard board rate. Refinancing at that point is how you avoid paying more than you need to.
Why Refinancing Is Worth Doing in 2026
The Singapore mortgage market is now priced off the Singapore Overnight Rate Average, which replaced the old SIBOR benchmark in 2024. As interest rates have been normalising and SORA has eased, banks have been offering competitive promotional packages to win new customers. That means there is a real chance to lock in a lower rate than your current bank is offering. You can track the current benchmark and theMonetary Authority of Singapore for guidance on how bank lending rates are set.
How Much Can You Actually Save
Consider a $500,000 loan at 3.2% per year with 25 years remaining. Moving to a 2.6% package reduces your yearly interest cost by roughly $3,000 in the first year, and the savings grow as the loan amortises. Over the full tenure, the difference in total interest paid can exceed $40,000. Even after accounting for the one-off costs below, the net gain is often substantial.
When Refinancing Does Not Pay
Refinancing is not always the right move. Your loan may still be inside its lock-in period, which means an early exit penalty of 1.5% or more of the outstanding amount. The total costs of switching can also eat up the rate advantage on a small loan. As a rule of thumb, ask yourself: will the interest savings over the next two to three years be larger than the combined legal, valuation, and penalty fees? If not, wait.
Refinancing vs Repricing: Know the Difference
Many borrowers confuse refinancing with repricing, but they are not the same thing. Understanding the distinction helps you choose the cheaper, simpler path.
- Repricing is when you switch to a different rate package offered by the same bank. It does not involve a new loan, so legal and valuation fees are usually waived and the process is fast. Some banks still impose a repricing fee of around $100 to $500.
- Refinancing is when you move your loan to a different bank. The new bank pays off your old loan and takes over the mortgage on the same property. This is where the biggest rate savings usually come from, because new customer packages are the most competitive.
If your current bank offers a low repricing package, take it first. It is nearly free. Only move to refinancing if the rate gap after fees is clearly better.
The Costs of Refinancing a Home Loan in Singapore
Refinancing is not free. You need to budget for several one-off costs before you get to the savings.
Valuation Fee
The new bank will run a valuation on your property. This typically costs between $150 and $300. When you compare packages, ask the bank to cover this fee as part of the promotion.
Legal Fees and Lawyer Subsidy
Agreements are prepared by a law firm, and the legal fees range from $1,500 to $3,000 depending on the loan size and law firm. The good news is that most banks will subsidise the legal fees by giving you either a cash grant or a higher credit limit on an accompanying credit card.
Early Repayment Penalty
If your current loan is still inside its lock-in period, you will pay a penalty of about 1.5% of the loan amount. This is the single biggest reason to time your refinance just after the lock-in expires. On a $500,000 loan, a 1.5% penalty is $7,500, which often erases the benefit of moving.
Nothing to Pay to the Government
Refinancing does not trigger Additional Buyer's Stamp Duty or any other property tax. The property is not being transferred, so the duties that apply to purchases do not apply to a refinance. You may, however, need to update your mortgagee details with theHousing Development Board if your flat is an HDB property.
Step by Step: How to Refinance Your Mortgage
- Check your lock-in end date. Look at your mortgage statement or ask your current bank. The sweet spot is the month your lock-in expires, so you avoid the penalty.
- Get your current rate and remaining balance. Know exactly what you are paying and how much is left. This is your baseline for comparison.
- Compare packages from at least three banks. Focus on the effective interest rate for the first two to three years, not just the headline rate. Include the legal and valuation subsidies in your comparison.
- Apply for a Letter of Offer. The new bank issues a Letter of Offer within a few days. This is a conditional commitment to lend to you at the agreed rate.
- Engage a law firm to complete the paperwork. The new bank will assign a law firm or let you use your own. The law firm handles the discharge of the old mortgage and the registration of the new one.
- Finalise with a legal completion date. The new bank pays off your old bank, and your loan transfers. This usually takes four to eight weeks from application.
Choosing the Right Rate Structure
When you refinance, you will be offered a choice between a floating rate tied to SORA and a fixed rate for a set period. Your choice depends on your view of the market and your cash flow.
| Feature | Fixed Rate | Floating Rate (SORA) |
|---|---|---|
| Predictability | High, rate is locked | Low, rate moves with SORA |
| Best for | Borrowers who want certainty | Borrowers who expect rates to fall |
| Typical lock-in | 2 to 3 years | 2 to 3 years |
| Downside | You miss out if rates fall | Payments rise if rates climb |
Many borrowers split the difference by choosing a two-year fixed package, then refinancing again when it expires. This keeps you flexible without being fully exposed to rate swings.
When Is the Right Time to Refinance
Timing matters more than the perfect package. Refinance when your lock-in period ends and your current rate is meaningfully above the market rate. If rates have been falling and your bank is slow to reprice you downwards, rate cuts may not automatically flow through to your board rate. That is the moment a competitor bank's offer becomes attractive.
As a practical guideline, refinance when the interest savings over the next 24 months are at least twice the total fees involved. This margin protects you against unforeseen delays and covers the effort of switching.
Common Mistakes to Avoid
- Focusing only on the headline rate. A low first-year rate followed by a high board rate can cost you more over three years.
- Ignoring the lock-in penalty. Always confirm whether your current loan is still locked in before you commit.
- Forgetting the legal subsidy. A package with a lower rate but no subsidy may be more expensive once you add $2,500 in legal fees.
- Not checking your CPF accrued interest. If your loan is partially serviced by CPF, refinancing relates to the bank loan only. Your CPF accrued interest obligation is unchanged and still applies when you sell.
Frequently Asked Questions
How often can I refinance my Singapore mortgage?
There is no legal limit. You can refinance as often as your lock-in periods allow, but each switch costs one-off fees, so most borrowers do it once every two to three years.
Does refinancing work on an HDB loan?
An HDB concessionary loan means you borrow from HDB at a rate tied to the CPF Ordinary Account rate plus 0.1%. You cannot refinance with a bank while staying on the HDB loan. Refinancing applies to bank loans, including those taken out for HDB flats after you switch from the HDB loan.
Will refinancing affect my credit score?
In Singapore there is no consumer credit score that gets hit by switching mortgages. The new bank will do a credit check as part of your application, but a responsible refinance does not harm your standing.
Can I refinance if my property value has dropped?
Yes, but the new bank will lend based on the current valuation and your total debt servicing ratio. If your loan-to-value ratio has risen because of a lower valuation, you may need to top up the difference with cash or CPF.
Key Takeaways
- Refinancing means moving your mortgage to a new bank to secure a lower interest rate.
- Check your lock-in end date first, because the early repayment penalty can erase your savings.
- Compare effective rates over three years, not just the advertised first-year rate.
- Budget for valuation and legal fees, and ask the new bank to subsidise them.
- Consider repricing with your current bank before refinancing, since it is much cheaper.
