To upgrade, you generally need to finish your HDB MOP, then sell the flat and buy the new one. If you buy a private property while still owning the HDB flat, you may pay ABSD up front, but it can be refunded if you sell the flat within six months of buying the new home (or of its TOP, if it is still under construction). The refund is for married couples with at least one Singapore Citizen. As second-timers, upgraders now compete for fewer new EC units: for EC sites with tenders closing on or after 8 May 2026, first-timers get priority on 90% of units, and that priority lasts two years instead of one month.
The paths
- HDB to resale condo: flexible, but check ABSD and loan limits.
- HDB to new launch condo: long wait for completion; plan housing in between.
- HDB to EC: on EC sites with tenders closing on or after 8 May 2026, first-timers get priority on 90% of new units for two years, so upgraders have fewer chances early on.
Timing
Many upgraders sell the HDB flat first and rent while waiting for a new launch to complete, or negotiate an extended completion period on the sale. Costs to model: ABSD risk, bridging loan interest, two sets of legal fees and temporary rent.

Frequently asked questions
Do I pay ABSD when upgrading?
If you own an HDB flat when you buy a private home, it counts as owning a property for ABSD, but ABSD may be refunded if you sell the flat within six months and meet IRAS conditions (a married couple with at least one Singapore Citizen). Check IRAS.
