A lock-in period is the stretch at the start of a bank home loan, usually one to three years, when repaying early or switching to another bank triggers a penalty. On a bank loan the penalty is often around 1.5% of the outstanding amount, according to the CPF Board. HDB loans have no lock-in at all. If you are buying a private condominium, the lock-in is a clause you should read before you sign, not after your first rate review.
TL;DR
- Bank loans in Singapore typically lock you in for 1 to 3 years. Breaking the lock-in by refinancing or fully repaying often costs about 1.5% of the outstanding loan.
- The lock-in covers more than switching banks. Large partial prepayments can trigger it too, unless your bank allows a free yearly allowance.
- Clawbacks, legal fees and valuation fees come on top of the penalty, so the real exit cost is higher than the headline percentage.
- Ask for repricing quotes from your current bank first, then compare the total exit cost against the interest you would save.
- Read the lock-in clause and the notice period (one month for partial, two months for full repayment under ABS guidance) before you accept a loan offer.

What a lock-in period actually is
When a bank offers you a low starting rate, it needs the loan to stay on its books long enough to earn back its costs. The lock-in is that commitment. The CPF Board describes the trade-off as stability versus flexibility: bank loans may start with lower rates, but those rates move with market benchmarks such as SORA, and the lock-in protects the bank's minimum return.
Three features define it:
- A fixed window. Typically one to three years for bank loans, counted from the first disbursement. Some packages run longer, so confirm the exact term in your letter of offer.
- A trigger. Full redemption, refinancing to another bank, and often large partial prepayments.
- A charge. A percentage of the amount repaid or outstanding, plus any clawback of subsidies the bank gave you at the start.
The Association of Banks in Singapore lists lock-in periods and fees, in particular penalty fees for partial and early prepayment, among the features you should check before choosing a loan. That is a good instruction to follow literally: put the lock-in clause on your checklist beside the interest rate.
How much the penalty costs
The commonly quoted figure is about 1.5% of the outstanding loan, as the CPF Board notes for bank loans. Here is a simple illustration, not a quote from any bank:
| Outstanding loan | Penalty at 1.5% |
|---|---|
| $500,000 | $7,500 |
| $1,000,000 | $15,000 |
| $1,500,000 | $22,500 |
For a condominium buyer, loan sizes are large, so a small percentage turns into a five-figure sum quickly. Some banks charge less, and the exact rate depends on the package. Your letter of offer is the only document that states the figure that applies to you.
The costs that sit on top
The penalty is rarely the whole bill. According to the ABS home loan guide, leaving early can also bring:
- Clawbacks: the bank recovers incentives it gave you, such as legal fee subsidies or valuation waivers, if you refinance or repay before the agreed term ends.
- Legal fees for the new mortgage.
- Valuation fees for the new bank's assessment.
- Administrative charges if you do not give the required notice.
For private property the conveyancing bill alone can be meaningful. Our guide to conveyancing lawyer fees in Singapore explains why you should insist on an itemized quote.
Notice periods and the 10% allowance
Banks expect warning before you repay. The ABS guidance, updated in August 2026, says to give one month's notice for partial prepayment and two months for full redemption to avoid extra administrative charges. Miss the window and you may pay more even after the lock-in has ended.
Many people assume the lock-in only matters when switching lenders. In fact it covers any major unscheduled reduction of principal. Some banks let you prepay up to a stated share of the loan each year, for example 10%, without penalty even inside the lock-in, but going beyond it triggers the charge. Not every bank offers this, so ask for it in writing.
Repricing is not automatically free
Staying with your bank and moving to a cheaper package sounds painless. The ABS advises exploring repricing before refinancing, because a bank may waive some fees to keep you. But there are two traps:
- A new package usually starts its own lock-in period.
- If you reprice before your current lock-in ends, the bank may still claw back the subsidies you received at the start.
So before you call, find out the date your lock-in ends, and whether the clawback window runs longer than the lock-in itself. The two dates are not always the same.
HDB loan versus bank loan
The CPF Board states that an HDB loan has no lock-in, so there is no penalty for paying it off early. That flexibility is real, but HDB loans are for HDB flats. Buyers of private condominiums, including new launches, finance through banks. If you are moving from a flat to a condo, our HDB upgrade guide covers the sequence, and our overview of home loan options in Singapore compares the two loan types.
Is breaking the lock-in worth it? A simple test
Experts suggest refinancing decisions should be driven by arithmetic, not by the headline rate. Use this process:
- Find your exit cost. Add the penalty, clawback, legal fees, valuation fees and any admin charges.
- Estimate monthly savings. Compare your current monthly instalment with the new offer on the same remaining loan and tenure.
- Divide. Exit cost divided by monthly saving gives the break-even in months.
- Compare with your plans. If you expect to sell, upsize or downsize before break-even, switching loses money.
- Check the new lock-in. A new package restarts the clock, which limits your options again.
A worked example with made-up numbers: suppose your exit cost is $18,000 and the new package saves $300 a month. Break-even is 60 months. If the new loan has a three-year lock-in and you might sell in four years, the switch is a poor bet. If instead your bank will reprice with the exit cost waived or cut, the same $300 a month becomes straightforward.
Remember also that refinancing is more than a rate swap. The ABS guide notes extra steps such as re-applying for Home Protection Scheme exemption with the CPF Board for HDB-related loans, conveyancing and valuation. If you are curious how overcharge disputes are handled in other markets, one US-focused explainer on how mortgage overcharge settlements work shows why itemized statements matter, though Singapore rules and remedies differ.
Choosing a loan with the lock-in in mind
The lock-in interacts with the rate structure you pick. A floating package linked to SORA moves with the market, which makes the ability to exit more valuable. A fixed package may suit you if you intend to stay put. Our pieces on fixed versus floating loans for condo buyers and SORA versus SIBOR walk through the questions to put to your bank.
Questions to ask before accepting an offer:
- How long is the lock-in, and when exactly does it start for a new-launch purchase with progressive drawdowns?
- What is the penalty, and is it charged on the outstanding balance or the amount prepaid?
- Is there a free partial prepayment allowance?
- Is there a penalty if the property is sold? Some packages waive it for a sale.
- Which subsidies are subject to clawback, and for how long?
- What are the notice requirements?
If you are buying under construction, the lock-in clock and your drawdowns interact. Our progressive payment scheme guide explains how payments are staged. Also check how much you can borrow under the TDSR rules, because a tight loan limit leaves less room to restructure later.
Our perspective
We talk to buyers who focus on the interest rate in the first week and discover the lock-in only when a better rate appears two years later. In our view, the lock-in deserves equal billing. For owner-occupiers, who tend to stay put, a longer lock-in on a cheaper rate can be a fair deal. For investors, who may sell, refinance or restructure as rental income and rates shift, flexibility is worth paying for.
Our advice is practical. Choose the package that fits how long you expect to hold the unit, write the lock-in end date in your calendar the day you sign, and request a repricing quote from your bank a few months before it. A buyer at a development like ours, where the units suit long-term living and rental alike, should plan the loan around the holding period rather than around the lowest advertised rate. We are not a lender or a financial adviser, so confirm the terms with your bank and, for your own circumstances, a qualified professional.

FAQ
Does the lock-in apply if I sell my property?
It depends on the package. Some bank loans waive the penalty when redemption is due to a sale of the property, while others do not. Ask your bank to confirm this in the letter of offer before you accept.
Can I make partial prepayments during the lock-in?
Often yes, up to a limit. Some banks let you prepay up to about 10% of the loan each year without penalty, and charges apply beyond that. The allowance varies by bank, and you should give one month's notice under ABS guidance.
Is there a lock-in on an HDB loan?
No. The CPF Board states that HDB loans carry no lock-in and no penalty for early repayment. This applies to HDB loans only, not to bank loans for private condominiums.
Does repricing with my own bank avoid the penalty?
Not always. A new package often starts a fresh lock-in, and clawback of earlier subsidies can still apply if your original lock-in has not ended. Ask for the full cost in writing before agreeing.
What should I do before my lock-in ends?
Request repricing quotes from your current bank and compare them with outside offers a few months ahead. Work out the total exit cost and break-even period, and give the required notice if you plan to repay.
