Start from the question you actually have. Everything here is free, none of it asks for an email, and every figure shows the rate it used and when that rate was last checked.

What are you trying to work out?

Quick answers

Four short ones that need a figure and nothing else. Each has its own link, so you can send someone straight to the stamp duty answer rather than to this page.

You will get: Both buyer’s duties on one price, banded, with the rate each band used.

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.
