Refinancing Your Home Loan in Singapore: Guide to Mortgage Refinancing, Eligibility, Costs and Steps

Yannie Woon 13 October 2025

Key Takeaways

• Refinancing a home loan in Singapore means switching banks to reduce interest costs, gain better features, or secure fixed repayments for cash flow stability.
• Choose refinancing over repricing when competitor rates remain lower even after accounting for fees, or when seeking fixed rate options not offered by your current bank.
• For owner-occupied properties, TDSR rules typically do not apply, but refinancing investment or cash-out loans is subject to a 55% TDSR threshold.
• Switching from an HDB loan to a bank loan is permanent, there is no penalty for switching, but you cannot revert to HDB financing later.
• CPF OA can still be used for repayments after refinancing, and HPS coverage is usually adjusted automatically to reflect your new loan terms.
• Refinancing involves legal, valuation, and potential lock-in costs; calculate your break-even point to ensure net interest savings.
• Start the refinancing process 3–6 months before your lock-in ends to secure approvals, align completion dates, and avoid early redemption penalties.
• Licensed moneylenders in Singapore do not offer mortgage refinancing; always verify lenders through the Ministry of Law’s registry.

Refinancing means switching your existing housing loan to a new package with another bank to achieve a lower interest rate, better features or payment stability. Homeowners commonly review their mortgage every two to three years, typically just before lock in expiry or when a rate reset is coming up.

The aim is simple, reduce total interest paid, smooth out monthly cash flow, or both.Refinancing makes sense when your current rate is higher than competitive alternatives by a meaningful margin after accounting for legal and valuation fees.

It also helps when you want predictable repayments using a fixed package, or when promotional subsidies can offset most of the switching cost. If your current bank offers a strong repricing package, you should compare both paths side by side before deciding.

Refinancing vs Repricing, Which Saves More?

Refinancing means switching your mortgage to a different bank. You go through a fresh application and the new lender pays off your existing loan. It can unlock sharper headline rates and sometimes legal subsidies. You will incur legal and valuation fees, and if you are still within a lock in period you may face break penalties or clawbacks on earlier subsidies.

Repricing keeps you with the same bank, moving you to another in house package. It is typically faster, with minimal documentation and no new lawyer needed. Repricing can be cost effective when your bank’s offer is close to the market leaders or when you are very near a rate reset.

However, do not assume loyalty guarantees the best price, compare both options based on total cost over the next one to three years.

When to Reprice

If your existing bank can match market rates after fees, if you want the simplest path, or you are inside a lock in and a penalty would erase savings.

When to Refinance

If a competitor’s package remains cheaper on a net basis, if you want a different peg or fixed rate not offered in house, or if you prefer a lender with better service or features.

Rules and Eligibility in Singapore

When refinancing an owner-occupied home, TDSR usually doesn’t apply, though banks still perform affordability and document checks.

For investment or cash-out loans, TDSR at 55% applies. Typical loan tenure caps are up to 30 years for HDB flats and 35 years for private properties, depending on age and bank policy.

LTV limits rarely constrain straightforward refinancing unless you’re increasing your loan amount. Standard documents like income proof, CPF history, and loan statements are still required, with extra checks for self-employed borrowers.

HDB vs Bank, What Changes After You Switch

Switching from HDB to Bank

You can refinance an HDB concessionary loan to a bank loan. There is no HDB penalty when doing so. Once you switch to a bank mortgage, you cannot later switch back to an HDB loan, it is a one way decision.

Bank loans typically offer promotional rates and more variety of fixed or floating packages, but they also come with lock in periods and early repayment clauses that you must review carefully.

Switching Between Banks

If you are already on a bank loan, refinancing to another bank follows standard bank to bank processes. If you prefer to stay with your current lender, you may ask for a repricing quote and compare that against market packages.

Using CPF and Your HPS After Refinancing

Using CPF for Instalments

CPF Ordinary Account funds can continue to be used for monthly instalments after you refinance. Your new bank will coordinate with CPF for deductions once your legal completion takes place. You should ensure the Giro and CPF arrangements are updated so that there is no missed deduction in the transition month.

Home Protection Scheme (HPS)

Home Protection Scheme, HPS coverage is tied to your outstanding housing loan when you are using CPF for instalments. After refinancing, your HPS cover is typically adjusted automatically to reflect the new loan amount and tenure if CPF usage continues.

You may receive notifications if there is a need to increase cover, update health declarations, or pay any premium shortfall. If you are not using CPF after refinancing, check whether HPS is still required or whether you should rely on private mortgage insurance instead.

Fixed vs Floating Packages in 2025

Fixed Rates

Fixed rates provide certainty. Your rate is locked for a fixed period, often two or three years. This suits homeowners who value predictable cash flow and want protection against rate spikes. The trade off is that fixed packages may carry higher break costs if you redeem or sell within the lock in, and when rates fall you will not benefit until the lock in ends or unless you reprice and accept any fees.

Floating Rates

Floating rates track a reference such as SORA or a bank board rate. They can be cheaper at the outset and allow you to ride potential rate declines. They suit borrowers with financial buffers who can tolerate some payment variability and who plan to review regularly. Keep an eye on reset intervals and caps or floors if any, plus any spreads that step up after the first year.

Fixed vs Floating, Quick Comparison

Costs, Subsidies and Break Even Analysis

Refinancing is not free. You will encounter a few common cost items and should evaluate savings net of these.

Legal and Valuation Fees

• Conveyancing for refinancing typically ranges by law firm and property type.
• Packages sometimes include legal subsidies that offset part or all of this cost, subject to clawback if you exit within a stated period.
• Valuation fees are payable for the new bank’s valuation. This varies by property type and size.

Lock-In Penalties and Subsidy Clawbacks

• If you redeem within your current lock in, expect a penalty based on a percentage of the outstanding loan.
• If you received earlier legal or valuation subsidies, a clawback may apply if you leave within a specified window.

Fire or Mortgage Insurance Adjustments

If policies are tied to the lender, you may need updates when you switch.

How to Find Your Break-Even Month

Compute total switching costs and divide by your expected monthly interest savings. Example: if costs are $2,000 and monthly savings are $180, your break even is roughly 11 months. If you plan to sell or prepay before that, consider staying put or repricing instead.

Typical Refinancing Cost Items

The Step by Step Refinancing Timeline

Lead Time: 3 to 6 Months Before Lock-In Ends

• Review your current loan: note your rate type, lock-in expiry, and any penalties.
• Decide on fixed or floating: shortlist packages that fit your goals and risk tolerance.
• Prepare documents: NRIC, payslips, CPF history, NOA, and property details.
• Apply for approval: secure an in-principle offer and valuation.
• Complete legal and redemption: your new bank redeems the old loan.
• After completion: update CPF, Giro, and check HPS and insurance coverage.

Investment Properties and Cash Out Refinancing

Refinancing for Investment Properties

Investment properties are subject to TDSR at the point of refinancing. If your existing total debt obligations exceed the 55 percent threshold, your ability to refinance with an increased amount or restructure terms may be constrained. Banks will also assess rental income treatment and any existing property count when considering risk based pricing.

Cash-Out or Mortgage Equity Withdrawal Loans (MEWL)

These differ from a like-for-like refinance. They are treated as new borrowing secured on your property, so TDSR applies, and LTV limits will cap how much equity you can withdraw. Expect different pricing and documentation requirements. If you are exploring cash out for investment or large expenses, review the risks carefully and compare with alternatives such as staged prepayments and maintaining a liquidity buffer.

Mistakes to Avoid

Missing Clawback Fine Print

Leaving a bank too early may trigger repayment of earlier legal or valuation subsidies.

Ignoring Lock-In Penalties

Calculate whether a penalty erodes the rate savings you expect.

Skipping Repricing

Always request your current bank’s best in house offer and compare net of fees.

Overlooking Legal and Valuation Costs

Include them in your break even analysis.

Switching HDB to Bank Without Commitment

Once you move from HDB to a bank loan, you cannot switch back later.

Compare Packages and Get Help

Estimate Savings

Check your monthly savings and break-even point after fees.

Shortlist Packages

Compare at least one fixed and one floating plan on the same rate assumptions.

Time Your Switch

Ensure completion happens right after your lock-in ends to avoid penalties.

Compliance and Consumer Protection Notes

Banks’ housing loans follow MAS rules. For owner-occupied refinancing, TDSR usually doesn’t apply; however, a 55% TDSR limit applies to new, investment or equity-withdrawal loans.

Tenure caps are typically 30 years for HDB flats and 35 years for private properties, depending on age and bank policy.

You can refinance an HDB loan to a bank loan without penalty, but cannot revert to HDB later. CPF OA may still be used for instalments, with HPS coverage automatically adjusted.

Licensed moneylenders do not offer mortgage refinancing, and borrowers should only deal with licensed lenders under MinLaw guidelines.
