How Home Loan Refinancing Works in Singapore (2026 Guide)

Key Takeaways

• Refinancing means replacing your existing mortgage with a new one – your new bank pays off your old bank, and you repay the new bank instead.
• Most homeowners refinance every 2–3 years when their lock-in period expires to avoid reverting to the bank’s higher revert rate.
• Typical costs include legal and valuation fees, but many banks fully subsidise these – your net out-of-pocket cost can be close to zero.
• Once you switch from an HDB loan to a bank loan, you cannot switch back – this decision is permanent.
• Start reviewing your options 3-4 months before your lock-in ends. The process takes time and rushing means you risk paying a higher rate in the gap.

Bank home loan rates in Singapore have dropped sharply. For homeowners whose lock-in period is expiring – or those still sitting on an HDB concessionary rate of 2.60% – the gap between what you are currently paying and what you could be paying has rarely been wider.

Yet many homeowners delay reviewing their mortgage because how home loan refinancing works is not well understood. This guide breaks down the refinance process from start to finish: what it is, how to do it, what it costs, and how to refinance your home loan in Singapore without leaving money on the table.

What Is Home Loan Refinancing?

Home loan refinancing is the process of replacing your existing mortgage with a new loan – usually from a different bank – to get better terms.

It does not involve buying a new property. You are simply renegotiating the debt you already have: the interest rate, loan tenure, or loan type.

When you refinance, your new bank pays off the outstanding balance on your old mortgage. From that point, you owe the new bank instead, at whatever rate and terms you agreed.

HDB Loan vs Bank Loan: Key Difference

• Repricing (same bank). Switching packages within your current bank. Cheaper and faster, but rates are usually less competitive than a full refinance.

• HDB loan → Bank loan. You can switch out of the HDB concessionary loan (2.60% p.a.) to a bank loan at any time. Once you switch, you cannot return to an HDB loan.

• Bank loan → Bank loan. The most common scenario. You move to a new bank when your lock-in period expires – typically every 2–3 years – to secure a lower rate.

How Does Refinancing a Mortgage Work?

Here is exactly how refinancing a mortgage works in Singapore, from application to settlement:

• You compare rates. Shop across banks or use a mortgage broker to find the best available package. Always compare the effective interest rate (EIR), not just the headline rate.
• You apply to the new bank. Submit your income documents, loan statement, and property details. The bank issues a Letter of Offer within 3-5 working days.
• A lawyer handles the legal transfer. A conveyancing lawyer discharges your old mortgage and registers the new one. Your new bank usually provides a panel of lawyers and often subsidises the fee.
• Your new bank pays off your old bank. On the completion date, the new bank disburses funds directly to settle your outstanding balance. Your old loan is closed.
• You begin repaying the new bank. Your new monthly instalment – at the new rate and terms – starts the following month.

Example: How the Refinance Process Works

Situation: You took a 3.90% fixed-rate bank loan in 2024. Your 2-year lock-in ends mid-2026. Outstanding balance: $600,000, 25 years remaining.

Action: You refinance to a new bank at 1.55% fixed for 2 years.

Result: Monthly repayment drops from $3,133 to $2,414 – a saving of ~$719/month in monthly installments and total interest savings over 2 years of ~$29,140

Typical legal + valuation fees start from $1,765-$1,965, which are almost fully offset by the bank provided subsidies and cash rewards for a refinancing.

How to Refinance Your Home Loan in Singapore

How to refinance a home loan in Singapore comes down to five steps. Here is what to do – and when:

Step 1: Start 3-4 Months Before Your Lock-In Ends

Most bank loans have a 2-year lock-in period. Refinancing before it ends triggers a prepayment penalty – typically 1.5% of your outstanding loan amount. Time your application so the new loan kicks in immediately after your lock-in expires.

Step 2: Compare Packages Across Banks

Look at the full package – interest rate, lock-in period, fee subsidies, and clawback conditions. A mortgage advisor can access rates that banks do not advertise publicly and run the full comparison across lenders at no cost to you – the bank pays the referral fee. This single step is where most homeowners leave money on the table.

Step 3: Gather Your Documents

Having these ready speeds up approval:

• NRIC / Passport
• Last 3 months’ payslips (or NOA if self-employed)
• Last 3 months’ CPF contribution history
• Last 3 months’ bank statements
• Current loan statement (outstanding balance, interest rate)
• Property title or HDB flat details
• Latest property tax bill
• CPF housing withdrawal statement (if CPF was used)

Step 4: Submit and Negotiate

Once you choose a bank, submit your application. Do not accept the first offer – use competing bank offers as leverage to negotiate a lower rate, fee waiver, or cashback. Banks have discretion.

Step 5: Complete the Legal Process

After approval, your lawyer handles the mortgage discharge and registration. The entire refinance process typically takes 9–10 weeks from application to completion.

What Are the Benefits of Refinancing Your Home Loan?

Lower Monthly Repayments

A 0.05%–0.10% rate reduction on a $1,000,000 loan saves $250–$500 per year. Over a 2-year lock-in, that adds up meaningfully – before any impact on your total interest cost.

Reduce Total Interest Paid

If you keep your monthly payment the same after refinancing to a lower rate, more of each payment goes toward principal. This shortens your effective loan tenure and reduces your total interest significantly.

Cash-Out Refinancing (Private Property Only)

Private property owners can refinance for more than their outstanding balance and take the difference as cash. This is useful for renovations, education, or investment. Note: not available for HDB flats.

Debt Consolidation

Consolidating higher-interest personal loans or credit card debt into a lower-rate home loan can reduce your total monthly debt repayments and simplify your finances.

Switch Between Fixed and Floating Rates

Refinancing lets you move between loan types. If you expect rates to rise, lock in a fixed rate. If you expect rates to fall, switch to a SORA-pegged floating package. Repricing does the same thing within your current bank, but usually at a less competitive rate.

How Much Does It Cost to Refinance?

Cost	Typical Range	Notes
Legal / Conveyancing Fees	$1,400 – $1,800	Often fully subsidised by new bank
Valuation Fee	$150 – $500	Sometimes waived
Prepayment Penalty	1.5% of outstanding loan	Only applies if refinancing within lock-in period
Clawback Clause	Varies	If you refinance again within 2–3 years, bank may reclaim the subsidy

Tip: Always ask for any subsidies or cash rewards. Almost all banks offer one – it reduces your out-of-pocket cost to near zero in many cases.

How Do You Qualify for Home Loan Refinancing?

Banks assess your eligibility as if it were a new loan application. The three main criteria are:

Total Debt Servicing Ratio (TDSR)

MAS rules cap your total monthly debt repayments at 55% of gross monthly income. If your income has dropped or you’ve taken on new debts since your original loan, check that you still comfortably pass this before applying.

Loan-to-Value (LTV) Ratio

The bank will order a new property valuation. For most refinances, the maximum LTV is 75%. If your property value has fallen since your original loan, the amount you can refinance may be lower than expected.

Credit Score and Income Stability

A strong CBS credit score (ideally “CC” grade and above) and consistent income are what banks want to see. Self-employed borrowers should have at least 2 years of NOA ready.

When Should You Refinance Your Home Loan?

Good Times to Refinance

• Your lock-in period is ending. Start comparing rates 4–5 months before expiry so the new loan can take over seamlessly.
• Rates have dropped by at least 0.05% p.a. This is generally the minimum difference needed to justify refinancing costs.
• Your credit score has improved. A better score unlocks better rates and terms.
• Your financial goals have changed. Need to reduce monthly outgoings, shorten your tenure, or access equity? Refinancing gives you a lever.

When to Hold Off

• You are still in a lock-in period – unless savings clearly outweigh the 1.5% prepayment penalty.
• You are near the end of your loan. Refinancing costs may not be recovered in the remaining term if your loan amount is below $200,000.
• Your income or credit has weakened. You may not qualify for competitive rates and could end up with a worse deal.

What Are the Pros and Cons of Refinancing Your Home Loan?

Pros	Cons
✓ Lower monthly repayments	✗ Legal and valuation fees upfront
✓ Reduce total interest paid	✗ Prepayment penalty if still in lock-in
✓ Switch fixed/floating rate type	✗ Income & debt profile needs to be healthy
✓ Access equity (private property)	✗ Clawback clause if you refinance again soon
✓ Shorten loan tenure	✗ Notice period and paperwork (~8–10 weeks)

Frequently Asked Questions About Home Loan Refinancing

How does refinancing work?

Refinancing works by taking out a new loan to pay off your old one. Your new bank settles the outstanding balance with your old bank, and you start repaying the new bank at the new interest rate and terms. The property stays yours throughout – only the lender changes.

How does refinancing a mortgage work in Singapore specifically?

In Singapore, the refinance process involves appointing a conveyancing lawyer to discharge your old mortgage and register the new one. Banks often subsidise legal and valuation fees. The whole process takes 8–10 weeks. Most homeowners refinance when their 2–3 year lock-in period ends.

How to refinance a home loan in Singapore – what are the steps?

The refinance process has five steps: (1) compare bank packages, (2) apply and submit documents, (3) receive your Letter of Offer, (4) appoint a conveyancing lawyer, and (5) your new bank disburses funds to close the old loan. Start 3–4 months before your lock-in expires.

Can I refinance my HDB loan to a bank loan?

Yes. You can switch from an HDB concessionary loan (2.60% p.a.) to a bank loan at any time. However, the switch is one-way – you cannot return to an HDB loan afterward. With bank rates now available below 2.60%, this switch can save money, but model your numbers carefully first.

What is the difference between refinancing and repricing?

Refinancing means switching to a new bank – more paperwork, higher upfront fees, but access to the most competitive rates. Repricing means staying with your current bank but switching packages – faster (2–4 weeks), cheaper (~$500 admin fee), but rates are typically less competitive.

How long does the refinancing process take?

Allow 8–10 weeks from application to completion. Start comparing and applying 4–5 months before your lock-in ends to avoid any gap where you’re paying the bank’s revert rate.

Does refinancing hurt my credit score?

A new loan application triggers a credit enquiry, which causes a small, temporary dip in your CBS score. It typically recovers within a few weeks.

How often can you refinance a home loan in Singapore?

There is no legal limit. In practice, most homeowners refinance every 2–3 years when a lock-in expires. Refinancing too soon may trigger clawback fees or cancellation fees from your current bank.

5 Tips to Get the Most Out of Refinancing

1. Start early. Begin 3–4 months before your lock-in ends. The refinance process takes 8–10 weeks.
2. Negotiate. The advertised rate is rarely the best rate. Use competing offers to push for a sharper rate or waived fees.
3. Always ask for a fee subsidy. Legal fees, valuation fees, and cashback offers are all negotiable – but you have to ask.
4. Read the clawback clause. If a bank subsidises your legal fees, there is usually a 2–3 year clawback period. Factor this in if you plan to sell or refinance again soon.
5. Use a mortgage broker. A broker accesses rates not publicly advertised and handles the comparison at no cost to you – the bank pays the referral fee.

Final Thoughts: My Take as a Mortgage Advisor

Most homeowners who miss the right refinancing window don’t do so because they couldn’t find a better rate. They miss it because they started too late, didn’t know what to compare, or assumed the process was more complicated than it is.

The right refinance is rarely the lowest advertised rate. It’s the package that fits your current loan structure, your financial goals, and your timeline – assessed before the expensive phase begins, not after. That means knowing your lock-in expiry, understanding the full cost of switching, and having someone who can compare what different banks are actually prepared to offer you.

If you want to know whether now is the right time to refinance your home loan in Singapore, the best first step is to have your current loan reviewed by a mortgage advisor who has done this across hundreds of different borrowers. The comparison is free. The savings are real.
