HDB Lease Decay (Oct 2026)

Lease decay affects almost every aspect of financing and future saleability. 

Here are the key points to note:

🏦 CPF Usage is Prorated Long Before 20 Years

The 20-year mark is only the absolute floor. The critical threshold is the "age-95 rule."

Full CPF Use: If the remaining lease of the flat can last the youngest owner until age 95, the amount of CPF savings you can use is capped at the lower of the purchase price and the valuation price at the time of purchase.

Prorated Use: If the lease falls short of that (e.g., a 30-year-old buying a flat with 60 years left), your CPF usage is prorated based on the lease and your age . This means you will need significantly more cash upfront.

Under 20 Years: Absolutely no CPF Ordinary Account savings can be used. Almost impossible to obtain loan approval, so you need to be prepared for full cash payment.

💰 Housing Grants are Also Reduced

Prorated Grants: Similar to CPF, housing grants (like the Enhanced CPF Housing Grant) are paid in full only if the lease covers the youngest buyer to age 95. Otherwise, the grant is prorated . This reduces the amount of money available to offset your purchase.

📉 Loan Limits and Tenure Shrink

Lower Loan-to-Value (LTV): If the lease cannot cover the youngest buyer to age 95, the LTV limit is prorated downward. This means you must fork out a higher cash downpayment .

Shorter Tenure: The loan tenure is constrained by the remaining lease (typically remaining lease minus 20 years, capped at 25 years or age 65). A shorter tenure means higher monthly instalments, which may cause you to fail the Mortgage Servicing Ratio (MSR) even if you could afford the flat on a longer loan .

🏚️ Resale Value and Buyer Pool Shrink

Accelerating Depreciation: While value decline is gradual at first, it accelerates significantly once the remaining lease drops below 60 years . The pool of buyers who can finance the flat shrinks as the lease shortens further.

No "Lottery" on En Bloc: Do not buy an old flat hoping for SERS (Selective En bloc Redevelopment Scheme) to bail you out. SERS is highly selective and rare. There is no automatic compensation when the lease runs out; the flat simply returns to HDB .

💸 The Hidden Cost: Accrued Interest

CPF Refund: When you eventually sell the flat, you must refund the CPF principal used plus accrued interest back into your CPF account. If the lease has decayed significantly, the sale proceeds might barely cover this refund, leaving you with little to no cash proceeds for your next home .

Summary: Treat the "20-year rule" as the point of no return, but the "age-95 rule" is the point where your financing costs actually start to increase and your cash outlay rises. 

Always use the official CPF Housing Usage Calculator with the specific flat's lease and your age before making an offer .

CPF Housing Usage Calculator: The most critical tool to directly verify how much CPF can be used for a property with an remaining lease of less than 95 years (i.e., the "age-95 rule"). Requires input of the youngest owner's date of birth, property price, and remaining lease, among other information.

🏠 HDB Official Documents (Grants & Loan Restrictions)

Grants & Loan Ratio Restrictions: The HDB official document (PDF) mentions that the Enhanced CPF Housing Grant (EHG) requires the remaining lease to cover the youngest buyer until age 95, otherwise the grant will be pro-rated; simultaneously, the loan limit (LTV) will also be pro-rated due to insufficient remaining lease.

Reminder: When using the above tools, be sure to use the actual remaining lease (rather than the age of the property) and the date of birth of the youngest owner for calculations.
