Refinancing a Home Loan in Singapore (2026): A Real Case Study

Refinancing vs Repricing: What Each One Is

Almost every Singapore home loan is cheap for the first two or three years, then steps up. A fixed rate expires; a "thin" floating spread widens; a teaser discount falls away. When that happens you have two ways to get back to a good rate.

• Repricing — you stay with your existing bank and switch to one of their newer packages. There's usually a small conversion fee (a few hundred dollars), no redemption, and it completes quickly.
• Refinancing — you move the loan to a different bank offering a better rate. It needs roughly three months' redemption notice and fresh conveyancing, but the incoming bank often hands you a legal and valuation subsidy to win your business.

The right answer is whichever is cheaper after costs. The discipline is simple: get your own bank's repricing quote first, then check it against the rest of the market. If a competitor is meaningfully lower, you refinance — which is exactly what happened here. (Our when & how to refinance guide covers the timing rules in full.)

The Real Case — a S$1.2M Condo Stuck at 2.45%

A young married couple, both Singapore Citizens in their early thirties, own an owner-occupied condominium in the city fringe (RCR). They'd bought it a couple of years earlier for S$1,780,000 with a 75% loan — about S$1,335,000 — on a package priced around 2.45%, which was a sharp rate at the time.

By 2026 their outstanding balance had come down to roughly S$1,200,000, with 27 years left to run. Two things had changed. Their original lock-in was ending, so a redemption penalty was no longer in the way. And rates that had sat above 2% when they first borrowed had eased: fixed packages were now available from around 1.35%. They were paying a rate the market had moved well below.

Refinancing is a real transaction — a new loan with a new bank, redeeming the old one. The lower the rate gap, the bigger the case to move.

We compared all 16 banks and moved them to a package at 1.35% fixed for two years, with free repricing after 12 months — meaning if rates fall further during the first year, they can switch to a cheaper package with the same bank at no cost. The new bank gave a S$2,500 subsidy that covered the legal and valuation fees, and the expired lock-in meant no penalty to redeem the old loan.

The Numbers: S$645/Month, ~S$25,800 Saved

Here is the full arithmetic on a S$1,200,000 balance over the remaining 27-year tenure.

The headline saving is about S$645 a month — roughly S$7,740 a year back in their pocket. But the bigger story is interest: at the old rate they'd have paid about S$29,000 in interest in year one; at the new rate, about S$16,000 — ~S$13,000 less in the first year alone, and roughly S$25,800 less across the two-year fixed term.

There's a quieter win too. Because more of each lower payment now goes to principal, they pay down about S$5,300 more of the loan in year one — so they're paying less and building equity faster at the same time.

Why 2026 Was the Moment to Move

Timing made this work, and it's the part borrowers most often miss. The couple's original 2.45% looked great in its day — but a rate is only good relative to the market, and the market had fallen. Two windows lined up at once:

• Their lock-in had expired. Refinance while still locked in and the bank charges a redemption penalty (typically around 1.5% of the outstanding loan — about S$18,000 here), which usually destroys the saving. Outside the lock-in, that barrier is gone.
• Rates had dropped below their package. A gap of more than a full percentage point on a seven-figure loan is large — well past the rough threshold (around 0.3–0.5%) where a switch starts paying for itself.

The lesson isn't "rates are low, refinance now" — rates move. It's that the moment your lock-in ends, you should re-price your loan against the whole market, every time. A package that was sharp two years ago can quietly become one of the most expensive on your street. For where rates sit today, see current fixed vs SORA home loan rates.

Does TDSR Apply When You Refinance?

This is the question that worries people who've seen their income dip, taken on a car loan, or gone self-employed since they first borrowed. The reassuring answer for most homeowners: refinancing your own home is exempt from TDSR.

Two carve-outs matter, because they flip the rule back on:

• Cash-out / equity loans. If you refinance and also borrow extra against your equity, TDSR applies to that cash-out portion. (See cash-out refinancing.)
• Investment property. Refinancing a non-owner-occupied property is still subject to TDSR, unless you commit to a debt-reduction plan that meets MAS's conditions.

Our couple's loan was a straight owner-occupied refinance with no cash-out — so TDSR simply didn't gate it. The bank verified their income for its own files and approved. That's why this kind of refinance is usually far smoother than the original purchase application.

The Refinancing Route, Step by Step

An owner-occupied refinance is usually smoother than the original purchase — no TDSR gate, and the new bank often subsidises the legal and valuation cost.

A refinance is a real transaction — a new loan that redeems the old one — but it's routine when sequenced right:

1. 1Find your lock-in expiry and count back ~4 months. Most banks need about three months' redemption notice, so the work starts before your cheap rate even ends.
2. 2Get your bank's repricing offer, then compare the market. Price the easy option (repricing) first, then check all 16 banks. Refinance only if a competitor clearly beats it after costs.
3. 3Apply, value, and serve notice. The new bank issues a letter of offer, arranges valuation and legal work (often subsidised), and you serve the redemption notice to your current bank.
4. 4Completion lines up with your lock-in ending. The new loan takes over the moment the notice expires — no overlap, no penalty — and you start on the lower rate.

Start to finish, plan for about three to four months, governed by that redemption notice. Run the figures first with our refinance savings calculator.

Repricing vs Refinancing — Which Is Cheaper

Refinancing isn't always the winner. Sometimes your own bank's repricing offer is close enough that the switching effort isn't worth it. The trade-offs:

In this case the couple's existing bank couldn't match 1.35%, and the rate gap on a S$1.2M loan was far too large to leave on the table — so refinancing clearly won, especially once the subsidy wiped out the switching cost. On a smaller balance, or with only a few years left, repricing often makes more sense.

When Refinancing Is Worth It — and When It Isn't

It's worth it when

• You're past your lock-in (or within ~3–4 months of it) — so no redemption penalty, and you serve notice early.
• There's a real rate gap — as a rule of thumb, more than ~0.3–0.5%, or a saving of a few hundred dollars a month.
• Your outstanding balance is still large, so the rate gap outweighs the switching cost.
• It's owner-occupied with no cash-out — refinancing is TDSR-exempt, so approval is straightforward.

Wait, or just reprice, when

• You're still inside the lock-in — the redemption penalty (around 1.5% of the loan) usually swallows the saving.
• You're within your current bank's subsidy clawback period (often 3 years) — you'd have to repay the legal subsidy they gave you.
• The balance is small or the tenure short — the rate gap won't beat the fees, so repricing is cleaner.
• You want to cash out — do it, but remember TDSR applies to the cash-out portion, so size it first.

Frequently Asked Questions

It depends on the rate gap and your outstanding balance. In this 2026 case, a couple moved a S$1,200,000 condo loan with 27 years left from 2.45% to 1.35%. That cut the monthly repayment from about S$5,067 to S$4,422 — around S$645 a month — and saved roughly S$13,000 of interest in the first year and about S$25,800 over the two-year fixed term. As a rough rule, refinancing is worth exploring when the rate gap is at least 0.3–0.5 percentage points and your loan is still large.

Repricing means switching to a new package with your existing bank — quick, with a small conversion fee and no redemption. Refinancing means moving the loan to a different bank for a better rate, which needs roughly three months' notice and new conveyancing, though the new bank often subsidises the legal and valuation cost. Reprice when your own bank matches the market; refinance when another bank is meaningfully cheaper.

No. Since September 2016 MAS does not apply the 55% TDSR cap to refinancing of an owner-occupied residential property loan, so you can refinance even if your TDSR today would exceed it. The new bank still asks for income documents and runs its own light credit check, but that isn't the regulatory TDSR test. Exceptions: cash-out (an equity loan) is subject to TDSR on the cash-out portion, and refinancing an investment property is still subject to TDSR unless you commit to a debt-reduction plan.

Start looking about three to four months before your lock-in ends, since most banks need around three months' redemption notice. Refinance when there's a real rate gap, when you're past your lock-in so there's no penalty, and when your balance is large enough that the saving beats the switching cost. A fixed or teaser rate that has just reset higher is usually the trigger to act.

Refinance inside your lock-in and the bank charges a redemption penalty, typically around 1.5% of the outstanding loan, which usually wipes out the saving. You may also have to repay legal or valuation subsidies from your current bank if you're still within their clawback period (often three years). Outside those windows, the main costs are new legal and valuation fees — which the incoming bank frequently subsidises. Here, a S$2,500 subsidy covered them, so the switch cost was effectively zero.

Plan for about three to four months end to end. The binding step is the three-month redemption notice to your current bank. While that runs, the new bank handles your application, valuation and legal work, so completion lines up roughly when the notice expires. Applying early means the new loan takes over the moment your lock-in ends.

Yes — you can refinance an HDB concessionary loan to a bank loan to chase a lower rate, but it's a one-way move: once you leave the HDB loan you can't switch back. Weigh the lower bank rate against the stability of the HDB rate. See our HDB loan vs bank loan guide for the full comparison.
