Switching Banks When You Refinance: What to Check First

Switching a home loan from one bank to another can lower the rate, but the switch itself is not free. Legal fees, valuation costs, and any early repayment penalty on the existing loan eat into the saving, so the real question is not whether a rate is lower, but whether the switch pays for itself in time.

Money: The Real Cost of Moving Your Loan

A bank switch typically involves several separate charges rather than one: legal fees to discharge the old mortgage and register the new one, the new bank's own processing and administrative fees, a fresh valuation if the bank requires one, and, if the current loan is still within its lock in period or carries an early repayment clause, a penalty set out in the existing Letter of Offer. None of these figures are standard across banks or loan types, so the only reliable way to know the true cost is to ask the current bank for the exact penalty in writing and get an itemised quote from the new bank, rather than assume a typical range applies.

Timing: Repricing Is Not the Same as Refinancing

Before comparing outside banks, it is worth asking the current bank whether it will reprice the loan, meaning offer a new rate on the existing loan without discharging and re registering the mortgage. Repricing is usually faster and cheaper than a full refinance because it avoids the legal and valuation costs of switching lenders, even though the rate on offer may not always match what a competitor is advertising. Read repricing versus refinancing before comparing external quotes, since it changes what the actual break even point looks like.

If a switch does go ahead, remember that a lock in period on the current loan does not simply disappear because a better offer appeared elsewhere. Check the exact end date and any penalty that applies if the loan is left before it, since this alone can change whether switching now or waiting a few months makes more sense.

Safety: Read the Letter of Offer in Full

The costs and penalties discussed above are usually all disclosed somewhere in the Letter of Offer for the existing loan, but they are rarely gathered in one place. Before shopping for a competing rate, read the existing agreement specifically for its prepayment clause, any clawback of a legal or valuation subsidy if the loan is discharged early, and whether there is a conversion option that lets a rate be changed within the same bank without the costs of a full switch. A conversion option, where available, is sometimes the cheapest way to improve a rate without touching another bank at all.

Money: Why the Fixed Period Ending Is a Natural Trigger

Bank loans commonly carry a fixed rate for the first two to three years, after which the rate becomes variable and tracks a reference benchmark such as compounded SORA or the bank's own internal rate. Singapore banks must give advance notice, usually about 30 days, before that change takes effect, which is exactly the window in which it is worth comparing what the current bank will offer next against what a competitor is quoting. Waiting until the variable rate has already applied for several months before comparing options simply means paying more than necessary while the comparison is being done.

Safety: Working Out Whether the Switch Actually Pays Off

Add up every cost of switching, then divide it by the actual monthly saving a new bank's offer would give on the real outstanding balance, not an example loan, to get a break even period in months. Compare that figure honestly against how long the property or the loan will actually be kept, since a switch that only pays for itself after a sale or another refinance is expected is not really a saving. It is also worth considering whether the current bank's service and digital tools matter enough that a marginally higher rate is still worth staying for. None of this requires guessing: ask both banks for written numbers and do the arithmetic on paper before signing anything.

It also helps to confirm that switching does not push the loan past the tenure thresholds where MAS applies a lower loan to value limit, since a new bank sometimes proposes resetting the tenure back up as part of the offer. Check the new loan against the same Total Debt Servicing Ratio and, for an HDB flat or an Executive Condominium still within its minimum occupation period, the Mortgage Servicing Ratio, since a switch that fails either test simply will not be approved regardless of how attractive the headline rate looks.

Finally, remember that switching too often has its own quiet cost even when each individual move clears its break even point, since legal and valuation fees recur with every switch and add up over a decade of ownership. Treat each switch as its own decision made on that loan's own numbers, not as a habit to repeat every time a marginally better rate appears somewhere else.

A useful habit is to calendar the end date of the current lock in or fixed period the moment a loan is taken up, rather than waiting for a bank's reminder letter to prompt the comparison. Reminder letters usually arrive close to the deadline, which leaves little time to properly compare offers, request the CPF or cash figures needed, and instruct a lawyer before the fixed period actually lapses into a higher floating rate. Marking that date early turns the whole exercise from a scramble into a straightforward comparison done at a reasonable pace, with time to actually read what each bank sends back. A calendar reminder costs nothing and can save a genuine amount of money over the life of a loan, and it costs far less than the interest quietly given up by simply forgetting to compare offers in good time, well before the fixed period lapses into something noticeably costlier.
