Compare flats side by side
Two flats are rarely alike enough to judge on the asking price. Put up to 4 blocks next to each other and the differences that matter — the lease, the floor area, what each costs for every month you get — line up in a single column each.

The same flat type, side by side
A block median mixes whatever happened to sell. If one block traded two-room flats last year and another traded five-room ones, their medians are not comparing like with like — so here each flat type is given its own row, and a blank means that block sold none.
| Flat type | Block 517 |

| 4 Room | $429,000$377 psf · 1136 sq ft · eight sales |
| 5 Room | $575,000$412 psf · 1345 sq ft · seven sales |
The sales behind the medians
The most recent transactions at each block, as HDB recorded them. Where a median rests on two or three sales, this is what those sales actually were.
