Most 99-year HDB flats in Singapore tend to be sold in the resale market after meeting the 5-year Minimum Occupation Period (MOP), with significant resale activity commonly occurring when flats are between 5 and 30 years old.
Many owners choose to sell after MOP for reasons such as upgrading or cashing out, but resale listings and transactions remain healthy for flats up to around 30 years old, as seen in recent transactions on EdgeProp Singapore. Flats older than 30 years may start to face some price resistance and slower demand because of lease decay concerns, though they are still regularly transacted, especially if located in mature or popular estates.
As the flat's remaining lease drops below 60 years, the pool of buyers can shrink further since financing and CPF usage are increasingly restricted. Despite this, there are still transactions for HDBs up to 40 or even 50 years old, but volume tends to taper off as flats age further.
