Key Takeaways
- • A lock in period is the window, typically 2 to 3 years, in which redeeming or refinancing the loan triggers a penalty, commonly around 1.5% of the outstanding amount.
- • Many packages also include a clawback: if you exit during the lock in or a separate clawback window, you must repay the legal and valuation subsidy the bank gave you.
- • A no lock in package lets you refinance or redeem freely but usually prices slightly above an equivalent locked package.
- • Lock ins are not automatically bad. If you intend to hold the property and the loan for the full term, the lower rate of a locked package is the better deal.
- • A no lock in package is worth the small premium when you plan to sell soon, expect to refinance, or are unsure of your holding horizon.
When you compare home loan packages in Singapore, the headline interest rate gets all the attention. The lock in period gets almost none, until you need to exit the loan early and discover a penalty you did not budget for. The lock in is a real cost, and it deserves the same scrutiny as the rate itself.
What exactly is a mortgage lock in period?
A lock in period is a contractual window, set in your home loan agreement, during which the bank will charge you a penalty if you fully redeem the loan, sell the property and pay off the loan, or refinance to another bank. Lock ins are typically two to three years long, often matching the period over which the package offers its promotional rate.
The penalty is usually expressed as a percentage of the outstanding loan amount, commonly around 1.5%. On a $700,000 outstanding loan, a 1.5% penalty is roughly $10,500, paid to the bank for exiting early. Penalties may also apply to large partial prepayments above an allowed threshold during the lock in.
What is the legal subsidy clawback, and how does it differ?
This is the part buyers most often miss. To win your business, many banks subsidise your legal conveyancing fees, and sometimes the valuation fee, when you take the loan. That subsidy is conditional. If you redeem or refinance within a defined clawback window, you have to repay the subsidy to the bank.
The clawback window is sometimes the same as the lock in period and sometimes longer, three years is common, even on a two year lock in. So a package can be technically "out of lock in" but still claw back the subsidy if you leave too soon. Always check both the lock in period and the clawback period separately.
Lock in versus no lock in: how do they compare?
| Feature | Package with lock in | No lock in package |
|---|---|---|
| Interest rate | Usually lower | Usually slightly higher |
| Early redemption penalty | Yes, during lock in (≈1.5% of loan) | None |
| Legal / valuation subsidy | Often offered, with clawback | Sometimes offered, sometimes not |
| Freedom to refinance | Restricted until lock in ends | Free at any time |
| Best for | Buyers holding the property and loan for the full term | Buyers expecting to sell or refinance soon, or unsure |
Indicative comparison. Exact rates, penalties, and clawback terms vary by bank and package, confirm with the lender's letter of offer.
When should you avoid a lock in, and when should you accept one?
The decision is about your plans, not the package in isolation. Accept a lock in when you genuinely expect to hold the property and keep the loan for the full lock in term. In that case the lower rate of the locked package simply saves you money, and the penalty is irrelevant because you will not trigger it.
Lean toward a no lock in package, and pay the small rate premium, when any of these apply: you may sell the property within the next couple of years; you bought a new launch and might exit before completion; you expect interest rates to fall and want the freedom to refinance; or you simply cannot predict your holding horizon. The flexibility is cheap insurance against a penalty that can run into five figures.
Winfred's Take
I have seen clients chase a rate that was 0.1% lower and walk straight into a five figure penalty when life forced an early sale. The lock in is not a footnote, it is a term of the contract with a real price tag. The honest test is simple: can you say, with confidence, that you will still own this property and hold this loan for the full lock in period? If yes, take the cheaper locked package. If there is any real chance of selling, upgrading, or refinancing sooner, a no lock in package, or at least the shortest lock in available, is worth the small premium. Match the loan to your plans, not your plans to the loan.
What about lock ins on a new launch property?
If you are buying a property under construction on the Progressive Payment Scheme, the lock in interacts with the build timeline. Banks may offer packages tailored to a property under construction, and the lock in clock can be structured differently. The key is to align the end of any lock in with when you might realistically need flexibility, for example if you intend to sell on completion. Discuss the build schedule with the bank when choosing the package.
Whichever package you choose, the lock in does not change the regulatory ceiling on your loan. According to the Monetary Authority of Singapore, your borrowing is still bound by the Total Debt Servicing Ratio (55% of gross monthly income) and the Loan to Value limit (75% for a first housing loan), and refinancing at the end of the lock in means a new bank re runs that TDSR assessment. So the lock in affects when you can move and at what penalty, not how much you can borrow.

Frequently asked questions
How long is a typical lock in period in Singapore?
Most fixed and floating packages carry a lock in of two to three years, usually matching the promotional rate period. Some packages offer no lock in at all, typically at a slightly higher rate. Confirm the exact term in the letter of offer.
How much is the early redemption penalty?
It is commonly around 1.5% of the outstanding loan amount, though it varies by bank and package. On a large outstanding balance this can run well into five figures, which is why it should be budgeted before you sign.
Can I sell my property during the lock in period?
You can sell, but redeeming the loan to complete the sale during the lock in triggers the penalty, and possibly the legal subsidy clawback. There may also be a separate tax cost: according to IRAS, Seller's Stamp Duty applies if a residential property is sold within the holding period after purchase, which is unrelated to the loan lock in but can compound the cost of an early exit. If you anticipate selling soon, choose a no lock in package or factor both the penalty and any SSD into your net proceeds.
Does the lock in stop me from making extra repayments?
Most packages allow a limited partial prepayment during the lock in without penalty, often up to a set percentage of the loan per year. Prepayment above that threshold can attract a charge. Check the partial prepayment terms specifically.
Is a no lock in package always better?
No. A no lock in package usually costs slightly more in rate. If you are certain you will hold the property and the loan for the full term, the cheaper locked package wins. The no lock in premium only pays off if you actually use the flexibility.
The bottom line
A lock in period is a price you pay for a lower rate, and a no lock in package is a price you pay for freedom. Neither is universally right. Decide based on how long you genuinely expect to hold the property and the loan, and always read the lock in and clawback terms before you sign.
