Refinancing may reduce your total home-loan cost, but the best time depends on more than the advertised interest rate. Check your lock-in period, outstanding subsidy clawback, legal and valuation costs, remaining loan tenure, and the risks of the replacement package before switching.
For HDB flat owners, refinancing an HDB housing loan with a financial institution is possible, but HDB states that the loan cannot subsequently be refinanced back with HDB. Read the current HDB loan matters guidance before making that decision.
What refinancing means in Singapore
Refinancing means replacing your existing home loan with a new loan from a different financial institution. The new lender typically repays the old lender, and you continue making repayments under the new package.
Repricing means changing to another package with your existing lender. Repricing may involve fewer administrative steps, but the available rates, incentives, and conditions depend on the existing bank’s offer.
A useful rule is to compare the net financial benefit, not the headline rate:
Net benefit = interest and fee savings − switching costs − clawbacks − value of lost benefits.

When to refinance your home loan in Singapore
Start reviewing your loan when one or more of these conditions apply:
- Your lock-in period is ending or has already ended.
- Your current interest rate is materially higher than suitable available packages.
- Your monthly instalment has increased and your budget needs more stability.
- Your outstanding balance is large enough for potential savings to cover switching costs.
- You expect to hold the property for longer than the new package’s lock-in period.
- Your current package has an upcoming repricing, interest-rate reset, or incentive expiry.
Do not treat the end of a lock-in period as an automatic instruction to refinance. It is a review date. A repricing offer from the existing lender may have lower transaction costs, while a refinance may provide a better rate or package structure.
Start earlier than the expiry date
Begin the review several months before the existing package expires. The exact lead time varies by lender, property type, borrower profile, documentation, valuation, and legal process. Confirm the required notice period and completion deadline directly from the current loan documents and lender.
Waiting until the final weeks can reduce your choices. A delayed application may also leave insufficient time to complete legal documentation before the old package changes.
Understanding the refinance lock-in period
A refinance lock-in period is the period during which early redemption, switching, or certain changes may trigger charges under the loan contract. The duration and consequences vary by lender and package, so do not assume that all three-year lock-ins have identical terms.
Check the facility letter and terms for:
- Lock-in start date and end date.
- Early redemption fee and how it is calculated.
- Whether the fee applies to full redemption, partial prepayment, or both.
- Notice requirements before redemption.
- Subsidised legal or valuation expenses that may be clawed back.
- Conditions attached to cash rebates or other incentives.
- Any minimum holding, insurance, or account requirements.
Why the lock-in date matters
Switching before the lock-in ends can be worthwhile only if the economic benefit exceeds every exit and entry cost. For example, a lower rate may appear attractive but become uneconomic after an early-redemption fee, subsidy clawback, legal costs, and valuation fees.
If your lock-in expires soon, compare two dates: switching before expiry and switching after expiry. The first may secure a lower rate earlier, but the second may avoid a penalty. Request a written redemption statement and a written quotation for the new package before deciding.
What is a refinance subsidy clawback?
A refinance subsidy clawback is the repayment of benefits previously provided by the lender when the loan is redeemed or changed before the relevant period ends. Common examples may include subsidised legal fees, valuation costs, or cash incentives, depending on the package.
The amount is package-specific. It may be a fixed sum, a stated percentage, or another amount defined in the offer documents. Never estimate the clawback from a generic online example when the actual facility letter is available.
How to include clawback in your calculation
- Ask the existing lender for a redemption statement dated near the expected completion date.
- Request an itemised statement of every fee and subsidy that may be payable.
- Check whether the amount changes with the redemption date.
- Obtain the new lender’s written fee and rebate conditions.
- Compare the total cost over the period you expect to keep the new loan.

How to calculate the refinance break-even point
The break-even period is the time needed for monthly savings to recover the switching costs.
Break-even months = total switching costs ÷ monthly repayment savings.
Suppose the total cost of switching is S$4,800 and the new loan reduces the monthly repayment by S$240. The simple break-even calculation is:
S$4,800 ÷ S$240 = 20 months.
This is only a screening calculation. It does not account for changing rates, different loan tenures, amortisation, cash-flow timing, taxes, insurance, or the possibility that the borrower sells or refinances again before month 20.
Use a more complete comparison
Compare the outstanding balance and total interest under both options at the same future dates. Keep the remaining tenure consistent unless extending the tenure is an intentional decision. A lower monthly instalment caused by a longer tenure may increase total interest even when the new rate is lower.
Test at least three scenarios:
- Base case: the quoted new rate remains as specified by the package.
- Higher-rate case: a floating or SORA-linked rate rises after refinancing.
- Short-hold case: the property is sold or the loan is changed before the break-even month.
Homejourney’s refinancing calculator can help estimate repayments before you submit a request. You can also review Mortgage Refinance Break Even Calculator Singapore | Homejourney Guide for the calculation framework.
Interest-rate timing: fixed, floating, and SORA-linked loans
Singapore home-loan packages commonly use either fixed rates for a stated period or floating rates linked to a reference rate. A floating package may be expressed as a reference rate plus a spread. The reference rate, reset frequency, spread, floor, and conversion terms must be read together.
The Singapore Overnight Rate Average, or SORA, is the volume-weighted average rate of unsecured overnight Singapore-dollar interbank borrowing transactions. MAS publishes SORA on the next business day, and its methodology is based on eligible transactions reported by banks.
The chart below shows recent interest rate trends in Singapore:
A chart can show past movement, but it cannot guarantee the future cost of a SORA-linked loan. The relevant comparison is the full package: SORA or another reference rate, the bank’s spread, reset mechanics, payment date, and any floor or conversion provision.
Should you wait for rates to fall?
Trying to identify the lowest future rate is a timing risk. If your current loan is expensive and the break-even period is short, waiting may cost more than it saves. If switching now triggers a large clawback or early-redemption fee, waiting until the relevant date may be more sensible.
A practical approach is to set a decision threshold rather than predict the market. For example, proceed only if the verified net savings remain positive under a higher-rate scenario and the expected holding period exceeds the break-even period.
Track SORA information through the MAS SORA page, which explains the benchmark and its calculation methodology. Any live rate display or bank quotation should be checked for its timestamp, reference period, and package conditions.
Refinancing versus repricing
| Question | Refinancing | Repricing |
|---|---|---|
| New lender? | Usually yes | No |
| Potential switching costs? | Legal, valuation, administrative, and possible clawback costs | Usually fewer external switching steps, but confirm the lender’s fees |
| Rate and package choice | Can access packages from other participating lenders | Limited to offers from the existing lender |
| Best initial question | Does the net saving justify changing lenders? | Can the existing lender match a suitable alternative at lower friction? |
Compare both routes on the same assumptions. A lower nominal rate is not automatically better if it comes with a shorter lock-in, higher spread after the promotional period, or costs that are not fully rebated.
Refinancing costs to include
Your calculation should include all costs that apply to your property and package:
- Early redemption fee, if applicable.
- Subsidy clawback for legal, valuation, or other incentives.
- Legal fees and disbursements.
- Valuation fees, where applicable.
- Administrative or processing charges.
- Insurance or account-related requirements.
- Interest paid during timing gaps or transition periods.
- Costs associated with changing tenure or loan structure.
Ask for an itemised written quotation. Cash rebates may offset some costs, but a rebate is not a saving if it is conditional, delayed, clawed back, or outweighed by a higher rate.
Step-by-step refinancing process
- Review the current loan: record the outstanding balance, rate, reference mechanism, lock-in expiry, redemption fee, subsidy conditions, and remaining tenure.
- Request a redemption statement: ask the current lender for the amount required to redeem on a realistic date.
- Compare repricing and refinancing: obtain written offers and use identical assumptions for balance and tenure.
- Check eligibility: the new lender will assess the application, property, income, liabilities, credit profile, and required documents.
- Calculate the break-even point: include all costs and test higher-rate and shorter-hold scenarios.
- Review the new contract: check the lock-in, clawback, rate-reset formula, spread after the initial period, partial-prepayment terms, and conversion options.
- Complete legal documentation: allow time for valuation and legal work where required.
- Confirm completion: verify the old loan has been redeemed and the new repayment schedule is correct.
Documents commonly requested
Requirements vary by lender and borrower. They may include identity documents, income evidence, recent payslips or notices of assessment, CPF contribution information, existing loan statements, property documents, and details of other liabilities. Ask the lender or appointed adviser for the current checklist rather than relying on an old application.
How to compare bank packages safely
Homejourney allows users to compare refinancing options from participating major banks in one place and submit one request for guidance across available options. The comparison should be treated as a starting point, not a promise that every applicant will qualify for every package.
Use the refinancing calculator and loan-request flow to estimate repayments, review affordability, and request a callback. Confirm the final rate, eligibility, fees, lock-in, and clawback terms in the lender’s formal documents before accepting an offer.
When comparing packages, ask:
- What is the rate during the initial period?
- What is the formula after that period?
- Is the package fixed, floating, or SORA-linked?
- When and how often can the rate reset?
- What is the lock-in period?
- What happens if the property is sold or the loan is partially prepaid?
- Which legal or valuation costs are subsidised?
- What is the exact clawback amount and duration?
- Can the package be converted later, and at what cost?
HDB, private property, and investor considerations
Property type affects the process, eligibility, valuation, and available loan options. HDB owners should verify the current HDB rules and understand the consequence that an HDB loan refinanced with a financial institution cannot subsequently be refinanced back with HDB.
Private-property owners should review the loan contract, title and valuation requirements, ownership structure, and any sale or partial-prepayment plans. Investors should also assess vacancy risk, rental cash flow, tax matters, and whether a lower instalment depends on extending the loan tenure.
Do not use refinancing to create affordability that exists only because the loan term has been extended. Compare both monthly cash flow and total interest over the remaining holding period.
Common mistakes to avoid
- Waiting until the lock-in expiry is imminent before starting the review.
- Comparing only the first-year rate.
- Ignoring the post-promotional spread or reset formula.
- Leaving subsidy clawback out of the calculation.
- Assuming a cash rebate equals a guaranteed net saving.
- Comparing monthly instalments without comparing total interest.
- Using a future rate forecast as if it were certain.
- Failing to obtain a redemption statement.
- Accepting a package without reading partial-prepayment and sale conditions.
- Assuming refinancing approval is guaranteed.
A decision checklist
- Identify the current rate and remaining balance.
- Confirm the lock-in expiry and every applicable exit charge.
- Calculate the subsidy clawback using written figures.
- Obtain a repricing option from the current lender.
- Compare suitable refinancing packages using the same balance and tenure.
- Calculate break-even under base, higher-rate, and shorter-hold scenarios.
- Check whether the new package fits your cash-flow needs and risk tolerance.
- Read the formal offer and obtain independent professional advice if the terms are unclear.
Frequently asked questions
When is the best time to refinance a home loan in Singapore?
The best time is usually when verified net savings exceed all switching costs and you expect to retain the new loan beyond the break-even period. Review several months before the current package expires so you can compare repricing and refinancing options.
Can I refinance during the lock-in period?
Possibly, but an early-redemption fee, subsidy clawback, or other contractual charge may apply. Check the facility letter and request a written redemption statement before deciding.
What does refinance lock-in period mean?
It is the contractual period during which early redemption, partial prepayment, or other changes may trigger charges. The exact duration and covered actions differ by package.
What is a refinance subsidy clawback?
It is the repayment of an incentive previously provided by the lender, such as subsidised legal or valuation costs, when the loan is redeemed or changed before the applicable condition expires.
Is refinancing better than repricing?
Neither is always better. Repricing may involve less switching friction, while refinancing may provide access to a wider range of packages. Compare net savings, conditions, and expected holding period.
Should I refinance from a fixed rate to SORA?
That depends on your tolerance for payment changes, the SORA-linked spread, reset mechanics, fixed-rate alternatives, and expected holding period. SORA is a market benchmark, not a guaranteed forecast of your future mortgage rate.
Can I refinance an HDB loan with a bank?
HDB states that an HDB housing loan can be refinanced with a financial institution, but it cannot subsequently be refinanced back with HDB. Check the current HDB guidance and your eligibility before proceeding.
How much can refinancing save?
The saving depends on the outstanding balance, rate difference, remaining tenure, fees, clawbacks, and time you keep the new package. A simple screening formula is total switching costs divided by monthly repayment savings, but a full comparison should also model changing rates and principal reduction.
How early should I start refinancing?
Start several months before the existing package ends. The precise timing depends on the lender, valuation, legal work, documentation, and required notice period, so confirm the process directly with the relevant lender.
Do cash rebates make refinancing worthwhile?
Not necessarily. Include the rebate only after checking its eligibility conditions, payment timing, and clawback terms. Compare the net cost over your expected holding period.
Can refinancing lower my monthly instalment?
It may, if the new rate is lower or the tenure is changed. A lower instalment from extending the tenure can increase total interest, so compare both monthly cash flow and total repayment.
Is it safe to rely on a rate forecast?
No forecast is certain. Use forecasts only as scenarios and test whether the refinancing remains suitable if rates do not move as expected.
Where can I compare refinancing options?
You can use Homejourney’s refinancing calculator and request flow to estimate repayments and submit one request for guidance across participating bank options. Final approval and terms remain subject to the lender’s assessment and formal documents.
What disclaimer applies to this guide?
This article is general educational information, not financial, legal, tax, or mortgage advice. Rates, eligibility, fees, lock-in terms, subsidy clawbacks, and regulatory requirements can change and vary by lender, borrower, property type, and date. Verify the current official or lender documents and seek regulated professional advice where appropriate.
Refinancing is a timing and risk decision, not simply a search for the lowest advertised rate. Review the lock-in and clawback, calculate a conservative break-even point, compare repricing with refinancing, and use Homejourney’s calculator and loan-request flow as a practical next step before committing to a new package.
