Lease decay, explained without the panic
Older flats are often assumed to lose value steadily as the lease runs down. The sales record shows a slow decline for most of the lease and a much sharper one in the last 60 years or so, mainly because of the rules on CPF and loans.
HDB flats are sold on 99-year leases, and when the lease ends the flat returns to the state. That is the basis of a common warning: avoid older flats, because their value falls as the lease runs down. The sales data supports a milder version of that.
In the raw prices, the effect is hard to see
If lease were the main driver, older flats would be clearly cheaper. Often they are not. As the MRT guide shows, four-room flats with 80–85 years left sold for more than flats with ten more years, because the shorter-lease flats tended to be in central locations near the MRT. Age and location are tied together, and in the raw numbers location matters more.
To isolate the effect of lease, you need to compare older and newer flats within the same town, so that location stays roughly constant.
Within a town, the decline is gradual
Within a town, price falls by roughly 1% of the flat's value for each year of lease, or very roughly $3,000 to $6,000 a year on a mid-priced flat. Part of even that is because newer flats tend to have better layouts and locations. A flat with 90 years left and one with 80 years left are priced very similarly. For most of the range, the decline is slow.
The decline steepens below about 60 years
With location netted out, the decline is mild while a flat has plenty of lease left, and gets much steeper once the lease is short:
The main reason is financing. At around 60 years, the remaining lease no longer covers a young buyer to age 95. Below that point CPF can only be used on a pro-rated basis and the housing loan is smaller, and for shorter leases still, CPF and loans are largely unavailable. Fewer buyers can afford these flats, more of them are older buyers with cash, and prices adjust to match. The steeper decline in the data starts at about the same point as these rules.
What this means for you
Practical points
- With 70 or more years left, lease is a minor factor. Floor, location and condition affect the price far more.
- Pay attention below about 60 years. Your eventual buyers will face the same CPF and loan limits, so there will be fewer of them and they will need more cash.
- Check the financing first. Does the remaining lease cover the youngest buyer to age 95? That decides whether full CPF use and a full loan are available, both for you and for whoever buys from you later.
- Match the lease to your plans. A flat in a good location with 65 or more years left can make sense if you plan to live there and the numbers work. If you are counting on an easy resale or on passing the flat on, a short lease is where most of the risk is.
