Choosing the right home loan isn’t just about chasing the lowest home loan interest rates. It’s about understanding the full picture: the rules, fees, and conditions that shape how flexible your loan will be years down the line.
In Singapore’s 2025 market, where SORA-based housing loans have replaced older benchmarks like SIBOR, and borrowing rules are tighter under loan-to-value ratio and home loan eligibility limits, knowing your options can make the difference between saving thousands and paying avoidable penalties.
This home loan guide walks you through the key mortgage restrictions to consider before signing that offer letter. This will help you make an informed, future-proof decision.
Understanding Mortgage Restrictions
When deciding how to choose a home loan, many borrowers focus on comparing bank home loan interest rates or calculating monthly repayments. While that’s important, it’s only part of the story. The fine print, those small clauses on lock-ins, penalties, and clawbacks determines how much control you truly have over your financing.
A slightly lower housing loan interest rate may look attractive upfront but could come with high fees if you refinance early or make a partial prepayment. On the other hand, a package with a slightly higher home mortgage rate might offer the flexibility to restructure later without hefty penalties.
Let’s look at the most common mortgage loan interest rate restrictions in Singapore and what they mean for you.
1. Lock-In Periods: The Most Common Restriction
The lock-in period is the time during which you’re “locked” with a specific bank and can’t refinance or fully redeem your loan without penalty. In Singapore, lock-ins typically last two to three years, though some fixed-rate packages may stretch to five.
What it means:
During this period, you enjoy preferential home loan interest rates that are usually lower than the prevailing market. But if you try to refinance, sell your home, or repay your loan in full before the lock-in ends, the bank will likely impose an early redemption penalty, usually about 1.5% of your outstanding loan. For a $500,000 loan, that’s $7,500 straight out of pocket.
Some lenders offer a “sale waiver,” letting you sell the property without penalty, but this doesn’t always apply to refinancing. Always confirm whether the waiver covers sales, refinancing, or both.
When to opt for a lock-in:
If you plan to stay in your property for several years and want predictable home loan mortgage rates, a lock-in period makes sense. But if you foresee refinancing, upgrading, or selling within the next few years, consider a no-lock-in or short-lock-in package, even if the mortgage interest rates are slightly higher.
2. Partial Prepayment Penalties: The Cost of Paying Down Early
Many homeowners want the option to pay down their loans faster using bonuses, CPF top-ups, or investment gains. But not every housing loan welcomes early partial repayments.
If your loan is still within its lock-in period, partial prepayments can attract the same 1.5% penalty on the prepaid amount, unless your package allows free prepayment of 10%–20% (sometimes up to 50%) each year. You’ll usually need to provide at least one month’s notice before making the payment.
Some banks also require you to maintain a minimum outstanding balance, typically $200,000 after partial repayment, so always check that clause.
Why this matters:
A prepayment penalty can wipe out the savings you hoped to make from reducing your principal. For borrowers who expect extra cash flow in the near term, prioritising flexibility over the absolute lowest bank home loan interest rates is often the smarter move.
3. Repricing & Admin Fees: The Hidden Cost Of Staying Put
After your initial rate period expires, your bank may automatically shift your loan to a higher “board rate.” To avoid this, you can request repricing; switching to another loan package with the same bank.
Repricing is convenient, but it’s not always free. Most banks charge an administrative fee between S$200 and S$800. While that’s cheaper than full refinancing, it’s still a cost to consider.
Pro tip: Even if repricing looks simple, don’t skip comparing offers from other lenders. Many banks provide refinancing subsidies, often up to $2,000 for legal and valuation costs making it cheaper than repricing with your existing lender.
If you’re deciding how to choose a home loan that will stay competitive over time, include repricing fees and refinancing costs in your three-year cost calculation.
4. Breakage Fees: When Timing Really Matters
Breakage fees apply when you repay part or all your loan outside your interest reset period. For most SORA-pegged housing loans, interest resets after one or three months.
If you repay in between those reset dates, the bank may charge a break cost, calculated to cover its loss from fixing funds for that interest period. It’s not a flat 1–5%, the amount depends on the bank’s cost formula and when you make the repayment.
Avoiding the fee:
Align any full or partial repayment with your reset date. Your banker can confirm when your next reset occurs so you can plan the timing and avoid unnecessary charges.
5. Cancellation Fees: When You Change Your Mind
A cancellation fee applies when you back out of a loan before it’s disbursed. It’s usually 1–1.5% of the cancelled loan amount and is most common for new developments where loans are drawn progressively as the building is completed.
If you decide to switch lenders before your project reaches Temporary Occupation Permit (TOP), the bank may charge cancellation on the undisbursed balance. Always check this clause before committing; it can cost thousands for unfinished projects.
6. Legal Fee Subsidy Clawback: The Refinancing Catch
When you refinance, banks often offer a legal fee subsidy (capped around S$2,000) to cover your conveyancing and valuation costs. However, if you refinance again within three years, you’ll have to repay that subsidy, known as a clawback.
Even if a competing bank offers lower mortgage loan interest rates, switching too early could erase your savings once you factor in clawback costs.
Best practice:
When comparing packages home loan interest rate in Singapore, always review your average total cost over three years, not just the first-year rate.
7. Loan-to-Value (LTV) Ratio: The Silent Restriction On Borrowing Power
While not a “fee,” the loan-to-value ratio (LTV) plays a critical role in determining how much you can borrow.
For bank home loans in Singapore:
If you have no other housing loan, the maximum LTV is 75%, provided your loan tenure doesn’t exceed 30 years and doesn’t stretch past age 65.
If you already have one or more housing loans, your LTV limit drops to 45% or 35% depending on the loan count and tenure.
HDB concessionary loans also have a maximum LTV of 75% (revised in 2024).
Alongside LTV, the Total Debt Servicing Ratio (TDSR) capped at 55% limits your overall borrowing based on income and existing debts.
Why it matters:
A lower LTV means a higher cash or CPF outlay upfront, but it can also improve your home loan eligibility and access to better mortgage interest rates. Always ask your lender how they determine property value, some use the purchase price, while others rely on independent valuation, which can affect your approved loan size.
8. Balancing Flexibility & Cost: Finding the Sweet Spot
In 2025, most home loan mortgage rates in Singapore are either fixed for a short period or pegged to 1-month or 3-month SORA. Packages with no lock-in or free prepayment tend to come with slightly higher housing loan interest rates, while heavily restricted loans look cheaper upfront but limit your options later.
When deciding how to choose a home loan, ask yourself:
- Will I sell or refinance within the next three to five years?
- Am I likely to make lump-sum prepayments?
- Do I prioritise the lowest mortgage loan interest rates or long-term flexibility?
Your answers will reveal what matters more: savings today or control tomorrow. A good home loan guide doesn’t tell you which product is “best,” but which fits you.
Conclusion: A Smart Borrower Reads Beyond the Rates
A smart borrower knows that home mortgage rates are only half the story. The other half lies in the mortgage restrictions: lock-ins, clawbacks, breakage costs, and LTV rules that govern what you can and cannot do with your financing.
Take time to read the fine print, ask about all possible fees, and consider how each condition aligns with your goals. Whether you’re comparing options for home loan interest rate in Singapore or deciding between fixed and floating bank home loan interest rates, always weigh flexibility against cost.
When you understand the rules behind the rates, you’re not just choosing a mortgage; you’re building a strategy for financial freedom.
