Longer Loan Tenor: Benefits and Trade-Offs (2026)

A longer loan tenor lowers your monthly instalment, which protects your cash flow and lets you borrow more under the debt rules. The price is a lot more interest over the life of the loan. The 2016 version of this article said a short tenor saves little interest. That is true only for the first few years. Over the full loan, the gap is large. Your choice also changes your loan-to-value (LTV) limit, so check the limits before you choose.

At a glance

• Maximum tenor: 35 years for private property, and 30 years for a bank loan on an HDB flat. An HDB loan runs up to 25 years.
• LTV falls by 20 points if the tenor is above 30 years (25 years for an HDB flat), or if the loan runs past age 65. A first loan drops from 75% to 55%.
• On S$1m at 1.8%, a 30-year loan costs S$3,597 a month, against S$4,965 for 20 years. But the total interest is S$294,915 against S$191,519.
• You can have both. Take the long tenor, then repay at the shorter schedule when you can. That keeps your flexibility.

What the limits are in 2026

MAS sets the maximum tenor at 35 years for private property and 30 years for HDB flats. Two things lower the LTV limit:

1. The tenor is above 30 years, or above 25 years for an HDB flat.
2. The loan period runs beyond the borrower’s age of 65. For joint borrowers, MAS uses the income-weighted average age.

For a first housing loan, the LTV limit then drops from 75% to 55%. For a second loan it drops from 45% to 25%. The minimum cash you must pay goes up with it.

Say you are 38 and buy a S$1.5m condo. A 30-year loan ends when you are 68. That is past 65, so the 55% limit applies. You can borrow S$825,000 and not S$1,125,000. A 27-year loan ends at 65 and keeps the 75% limit. So the longest tenor is not always the best tenor. The right choice is often the longest one that stays inside the higher LTV band.

The HDB loan has its own rule. Its tenor is the shortest of 25 years, 65 minus the average age of the buyers, or the remaining lease minus 20 years.

The maths: S$1m at 1.8%

This table shows how tenor changes the cost of a S$1m loan at a fixed 1.8%. The rate is an example, close to today’s floating packages (about 1.5–1.8% in October 2026).

Tenor	Monthly instalment	Interest in first 3 years	Total interest over the loan
20 years	S$4,965	S$50,670	S$191,519
25 years	S$4,142	S$51,460	S$242,556
30 years	S$3,597	S$51,984	S$294,915
35 years	S$3,211	S$52,355	S$348,584

(A 35-year loan applies to private property only, and brings the 55% LTV limit.)

Two lessons follow. First, the 2016 point is right. Over the first three years, a 30-year loan costs only S$1,314 more interest than a 20-year loan. That is about S$438 a year, and your instalment is S$1,368 a month lower. Second, over the full term the 30-year loan costs S$103,396 more. The interest looks small early because most of each early instalment is interest on a large balance, for both loans.

So a long tenor is a cheap way to buy flexibility if you will keep the loan for three to five years. It is an expensive way to borrow if you will hold the loan for 30 years.

Benefit 1: A lower instalment protects your cash flow

A mortgage is only one of your costs. You also pay for insurance, property tax, utilities and maintenance. The lower the instalment, the easier it is to pay in a bad month. An instalment that takes most of your take-home pay leaves no room for a job gap or a repair bill.

Benefit 2: A bigger buffer against rate rises

Floating rates follow SORA, and 3-month compounded SORA peaked at about 3.7–3.8% in late 2023. Banks raised their offers after the US Federal Reserve hiked on 16 September 2026. If your rate rose to 4%, the S$1m loan would cost S$6,060 a month on a 20-year tenor and S$4,774 on a 30-year tenor. That is S$1,286 less per month, which may decide whether you cope.

Benefit 3: It helps you pass the debt tests

Banks test your loan against the Total Debt Servicing Ratio (TDSR). All your monthly debt payments must stay within 55% of gross monthly income, and for HDB flats the Mortgage Servicing Ratio caps payments at 30%. The bank tests at the higher of 4% or its thereafter rate.

Say your income is S$10,000 a month and you have no other debt. Your limit is S$5,500 a month. At the 4% test rate, that supports about S$907,600 of loan over 20 years, S$1,041,990 over 25 years, and S$1,152,040 over 30 years. The longer tenor raises your debt capacity by about 27%. (Ask your bank how it sets the tenor in the test.) Remember that the LTV limit and your cash may still cap the loan.

This is the point that matters for a second property. A longer tenor can decide whether you qualify at all. Use our TDSR guide to check your own ratio.

The costs and traps

• More total interest. See the table above. Over 30 years, it adds up to about S$103,000 on a S$1m loan.
• Slower equity growth. After five years of repayment, you still owe about S$868,000 on the 30-year loan, against about S$783,000 on the 20-year loan.
• A lower LTV limit if you go above 30 years, or past age 65.
• A shorter tenor may be forced on you later. The 2016 article said some banks only let you refinance for the remaining tenor. Ask your bank before you choose a very short one, because it may not be possible to lengthen it. Our refinancing guide explains the costs of switching.

The hybrid: long tenor, short schedule

You can take the 30-year loan and still pay it off in 20 years. Say you borrow S$1m at 1.8% for 30 years but pay S$4,965 a month, the 20-year instalment. At a constant 1.8%, the loan clears in 20 years, and the interest is S$191,519, the same as a 20-year loan. The difference is that in a bad year you can drop back to S$3,597.

Check three things first:

1. Lock-in penalties. Some packages charge a fee on partial repayment inside the lock-in. DBS charges 1.5% on early repayment, for example.
2. Notice rules. Banks usually want one month’s notice for a partial prepayment.
3. Your own discipline. The flexibility works only if you do pay the extra in good months.

How to choose

Ask three questions. How long will you really keep the loan? How much slack does your budget have at 4%? Does a shorter tenor keep you inside the 75% LTV limit and the age-65 limit? If you will sell or refinance within five years and your budget is tight, a long tenor costs little. If you will hold for decades and your income is stable, shorter is cheaper. Use the mortgage calculator to compare, and read how to choose a home loan for the other terms.

Bottom line

A longer tenor is a form of insurance. It costs you interest over the full loan, and it buys a lower instalment, a bigger buffer and more room under TDSR. Pick the longest tenor that keeps your LTV at 75%. Then decide how much extra to pay each month. Nothing here is personal financial advice.
