Buying a new launch or EC while owning your current home is a sequencing puzzle: progressive payments, the sale timing, ABSD remission windows. This planner lays the whole sequence out.
A consultant runs the full report for your exact situation, free, no obligation, one consultant, never a blast to agents.
Enter the price of the new launch or EC, your current home and your finances. The planner lays out the progressive payment stages from booking to the Certificate of Statutory Completion, shows which are paid in cash or CPF and when the loan starts to be drawn, and adds stamp duty and any ABSD. It then tests when you can sell your current home: before the purchase, during construction, or after the new home is ready.
A S$1.8 million new launch condo
If you still own your current home when you buy, ABSD applies on top; the planner shows when it can be recovered.

Under the normal payment scheme: 5% at booking, 15% when the S&P is exercised, then 10% at foundation, 10% at the concrete framework, 5% each for walls, ceiling, fittings and car park, 25% at TOP and the last 15% at the Certificate of Statutory Completion.
After the first 20%, which you pay from cash and CPF. The bank then pays each construction stage as the developer bills it, so instalments start small and grow as the building goes up, with interest charged only on the amount drawn so far.
Yes, and many buyers do, to release cash and avoid ABSD becoming permanent. The question is where you live until the new home is ready. The planner compares selling before the purchase, during construction and after TOP.
Buyers of a new EC must not have owned private property in the 30 months before applying. If they own an HDB flat, it must be sold within six months of collecting the EC keys, and the ABSD paid on the EC is remitted when it is. The planner applies these rules for EC purchases.
For a new EC bought from the developer, the household's gross monthly income must not exceed S$18,000 for ECs whose land tender closed on or after 24 Aug 2026; S$16,000 for earlier projects, including their balance units. The Mortgage Servicing Ratio also caps the loan instalment at 30% of gross monthly income.
