This is the rate you are offered, not the rate you are assessed at. A bank tests whether you could still service the loan at the MAS medium-term floor, which is higher — that is what decides how much you can borrow. What you pay each month is the figure above.

Rates last reviewed 2026-08-21. TDSR 55.0% · MSR 30% · stress rate 4%.
IRAS — Buyer’s Stamp Duty (effective 2023-02-15) · IRAS — Additional Buyer’s Stamp Duty (effective 2023-04-27) · IRAS — Seller’s Stamp Duty (effective 2025-07-04).
These are calculations against published rates, not advice, and not a substitute for IRAS or your banker.

And the lookups behind them

All of it is free, and that is the position rather than an introductory offer. The equivalent lookups on the competitor site — the price map, HDB by town, HDB by block, condos, landed, transactions and comps — are all behind a paid tier. These are the same seven, given away.
