What Is Refinancing?
Refinancing means replacing your existing home loan with a new loan — either from a different bank (external refinancing) or from the same bank on new terms (repricing). The goal is typically to obtain a lower interest rate, extend the loan tenure to reduce monthly payments, or switch from a floating rate to a fixed rate (or vice versa).
In Singapore, the refinancing market became significantly more active after the transition away from SIBOR and SOR (both now discontinued) to SORA (Singapore Overnight Rate Average) as the new benchmark for floating rate loans. Borrowers still on legacy fixed-rate packages that expired in 2023 or 2024 are among the most active refinancers in 2026.
When Does Refinancing Make Sense?
Refinancing is worth evaluating when any of the following conditions apply:
- Your current lock-in period has ended or is about to end. Most fixed-rate packages have a lock-in period of 2 to 3 years. Refinancing within the lock-in period triggers a prepayment penalty (typically 1.5% of the outstanding loan amount). Outside the lock-in period, you can refinance without penalty.
- Market rates have fallen since you took the loan. If current SORA spreads or fixed rates offered by banks are materially lower than your existing rate, the interest savings over the remaining tenure may justify the refinancing costs.
- You want to switch from floating to fixed (or back). Borrowers who took floating rate loans when rates were low may want to lock in a fixed rate. Those on higher fixed rates from peak periods may want to switch to floating.
- You need to restructure your debt obligations. Refinancing to a longer remaining tenure reduces monthly repayments, which can free up cash flow — but extends the total interest paid.
The Break-Even Calculation
Refinancing has upfront costs. The decision to refinance should always be assessed against the break-even timeline: how many months of interest savings does it take to recover the refinancing costs?
| Refinancing Cost Item | Typical Amount |
|---|---|
| Legal fees (conveyancing for new bank) | $1,800 – $3,000 |
| Valuation fee (some banks require fresh valuation) | $500 – $1,000 |
| Cancellation fee (if refinancing within lock-in period) | 1.5% of outstanding loan (can be $15,000+ on a $1M loan) |
| Mortgage duty (if applicable) | Usually waived on refinances; confirm with bank |
Many banks offer legal fee subsidies (typically $1,800 – $2,000) to attract refinancing customers. This subsidy often comes with a clawback clause — if the borrower refinances again within 3 years, the subsidy must be repaid.
Break-even rule of thumb: If the monthly interest saving is $300 and total refinancing costs (net of subsidies) are $3,000, the break-even is 10 months. If the borrower plans to sell within 12 months, refinancing may not be worth it. If they plan to hold for 5+ years, the savings are significant.
TDSR and MSR Apply on Refinancing
A common misconception among borrowers is that refinancing is a simple bank-to-bank transfer of the same loan. It is not — it is a new loan application, and MAS’s TDSR and MSR rules apply in full.
For most refinancers, the TDSR assessment is straightforward because the outstanding loan is lower than the original loan amount. However, refinancing can be rejected or result in a lower loan quantum if:
- The borrower has taken on additional debt since the original loan (car loan, personal loan, credit card balance), increasing total debt obligations above the 55% TDSR ceiling.
- The borrower’s income has decreased since the original loan was taken (e.g. changed from salaried employment to self-employment with lower assessable income).
- The loan tenor requested is shorter than the original, increasing the monthly repayment used in the TDSR calculation.
- The borrower’s age now constrains the maximum loan tenure (the age-65 cap applies at refinancing, not just at original purchase).
For HDB flat refinancers taking a bank loan (after leaving the HDB concessionary loan), the MSR 30% cap also applies. Monthly repayment on the refinanced HDB loan cannot exceed 30% of gross monthly income.
Repricing vs Refinancing
Repricing is the lower-friction alternative to full refinancing. Instead of switching banks, the borrower renegotiates the rate with their existing bank. Key differences:
| Feature | Repricing | Refinancing |
|---|---|---|
| Bank change | No — same bank | Yes — different bank |
| Legal fees | None (typically) | $1,800 – $3,000 (often subsidised) |
| Processing time | 1 – 2 weeks | 4 – 8 weeks |
| Rate competitiveness | Usually slightly higher than market | Best rates available across all banks |
| TDSR reassessment | May be required | Always required |
| Typical repricing fee | $500 – $800 (some banks waive this) | n/a |
Borrowers who prioritise speed and low friction often reprice first, then evaluate refinancing when the repriced rate becomes uncompetitive again. Banks generally accommodate repricing requests promptly because the alternative is losing the customer entirely.
Leaving the HDB Concessionary Loan
Borrowers who took an HDB concessionary loan (currently at 2.6% per annum, fixed at 0.1% above the CPF OA rate) can refinance to a bank loan. However, this is a one-way door: once a borrower fully or partially uses a bank loan on their HDB flat, they can no longer return to an HDB loan on that flat.
The HDB concessionary loan rate of 2.6% has historically been competitive against bank loan rates at the bottom of the rate cycle. In a rising rate environment, bank fixed rates may be higher than the HDB rate, making the HDB loan more attractive for risk-averse borrowers. CEA agents should flag this trade-off to clients who ask about refinancing out of HDB loans — but should not make the recommendation themselves.
Refinancing and Property Sales: Timing Issues
Clients who are planning to sell their property within 12 to 24 months should consider whether refinancing is worthwhile given the sell-side timing:
- If the borrower refinances into a new 2-year lock-in period and then sells before the lock-in ends, they face a prepayment penalty (1.5% of outstanding loan on redemption).
- If the borrower refinances to a package with no lock-in (these exist but typically carry a slightly higher rate), there is no penalty on full redemption when the property is sold.
- For clients who are undecided about selling, a floating rate package with no lock-in provides flexibility — at the cost of rate certainty.
Agent note: If your seller client mentions they recently refinanced, ask which package they took. A client who refinanced into a 2-year lock-in 6 months ago and now wants to sell faces a redemption penalty that will reduce their net sale proceeds. This should be factored into the transaction timeline and pricing strategy.
Using LEVR Before a Refinancing Decision
LEVR’s Home Loan Calculator allows agents to model the monthly repayment impact of refinancing at a new rate and tenure, and to stress-test whether the new repayment passes the TDSR ceiling.
The pre-refinancing checks worth running:
- New monthly repayment: Enter the outstanding loan balance, new rate, and remaining tenure. Compare against the current monthly repayment to quantify the saving.
- TDSR re-check: Use the client’s current income and all existing debts to confirm the new monthly repayment stays within the 55% TDSR ceiling — and 30% MSR if it is an HDB flat.
- Tenure impact: If the client wants to extend the tenure to reduce repayments, check whether the age-65 cap allows the extended tenure. A 50-year-old borrower cannot take a loan extending beyond their 65th birthday on most banks’ standard terms.
