Lease Decay Explained: The Thresholds That Matter

A 99-year leasehold property is on a clock. From the day the lease begins, it is slowly running down, and as it does, the property becomes harder to finance, harder to sell, and worth less. This is lease decay, and while it is gradual, it is not smooth. There are specific thresholds where the effect accelerates. This is lease decay explained, and the thresholds that matter.

Lease decay, broadly. Exact CPF and bank limits depend on your age and lender, so confirm them.

What lease decay actually is

Every 99-year leasehold property reverts to the State when its lease ends, with the land returning to the authorities and the owner left with nothing. Because of that, the value of the lease falls as it runs down. Crucially, the decline is not a straight line. Early on, a few years make little difference. Later, each year lost matters more, because fewer buyers can finance a short lease and everyone knows the clock is ticking faster. Understanding where those acceleration points are is the whole game.

The CPF threshold, the one most people hit first

CPF rules are the first real constraint, and they turn on a simple test. To use your CPF for a property, your age plus the property's remaining lease must reach at least 95.

• If your age plus the remaining lease is 95 or more, you can use your CPF in full, up to the Valuation Limit.
• If it is below 95 but the remaining lease is at least 20 years, you can still use CPF, but a reduced, pro-rated amount.
• If the remaining lease is 20 years or less, you cannot use CPF at all.

This matters when you sell as much as when you buy. A future buyer who cannot use CPF, or can use only a little, has to find far more cash, which shrinks your buyer pool and your price.

The financing threshold, where the cliffs begin

Banks apply their own version of the same logic. As the remaining lease shortens, the loan you, or a future buyer, can get is reduced, and the loan tenure is capped so it does not run too close to the lease end. In practice the financing starts to tighten noticeably as the lease falls toward and below about 60 years, and gets materially harder under 40 years. A property that only cash-rich buyers can fund is a property with a thin market.

Why the decline accelerates

Put the two together and you see why lease decay speeds up. As the lease shortens past these thresholds, each future buyer can borrow less and use less CPF, so they must pay more in cash. Fewer people can or will do that, demand narrows, and the price has to fall to clear. The closer to lease end, the steeper this gets, until in the final decades the property trades mainly among cash buyers at steadily lower values.

What it means when you buy

Lease decay does not make leasehold a bad buy. Most leasehold homes are bought with decades of lease left, well clear of the thresholds. But it should shape your decision:

• Check the remaining lease, not just the original 99 years, especially on an older resale.
• Think about who your buyer will be when you sell, and whether they will be able to finance it.
• Be cautious the closer a lease sits to the 60-year mark and below, where the market narrows.
• Weigh the lower entry price of a shorter lease against the harder exit later.

What it means when you sell

If you own a leasehold property, time is working against its value, so plan your exit with the thresholds in mind. Selling well before a major threshold, rather than after, protects both your price and your pool of able buyers. Leaving it until the lease is short, and the financing difficult, is one of the more avoidable ways to lose value.

A considered view

Lease decay is not a reason to avoid leasehold, but it is a reason to buy and sell it with open eyes. Know the remaining lease, understand the CPF and financing thresholds, and think a step ahead to your future buyer. If you are weighing a leasehold property, or holding one, I am happy to work through where it sits on the curve and what that means for your decision.
