For upgraders

Sell first, or buy first?

The trickiest part of upgrading isn’t the new home — it’s the sequence. Sell first and dodge ABSD but risk a housing gap; buy first and secure the home but pay ABSD upfront. Answer a few questions to see which fits your cash, timeline and nerve.

Can you fund the ABSD (~20%) upfront and claim it back later?

A guide, not advice — the right sequence depends on your finances, the market and your timeline. ABSD refund rules and timelines are set by IRAS/HDB and change; confirm before you commit.

Common questions

Should I sell my flat before buying the next one?

Selling first avoids Additional Buyer's Stamp Duty (ABSD) entirely and needs less cash, but you risk not finding a new home in time and may need interim housing. Buying first secures the home you want but you pay ABSD upfront (claimable back within 6 months for eligible couples) and face pressure to sell. Which is right depends on your cash buffer, timeline and the market.

Do I pay ABSD if I buy before selling?

Yes — buying a second property before selling your first means paying ABSD upfront (20% for a citizen's second home). A married couple with at least one citizen can claim it back if they sell their first home within 6 months of the purchase, but you need the cash in the meantime.
