Why a range, not one number. No record shows your floor, facing, renovation or lease, and where your unit sits inside this spread depends on them.

Floor, surroundings, nearby sales, afternoon sun and the history of the land—shown only where the public record carries enough to say something.

What the floor is worth

This block—

Too few filed sales at both ends of this block — it needs 3 high and 3 low. The figure beside is CHOA CHU KANG, not here.

CHOA CHU KANG, typical block+11.6%

Middle of 18 blocks in CHOA CHU KANG that clear the bar — half fall between +3.1% and +14%. 3 came out negative — high floors sold for less in 3 of them.

Every band in CHOA CHU KANG, for reference. Pooled across buildings, so it mixes the age of an estate with height; the two figures above hold a building constant.

The 1km band gives ballot priority, not a school place. These distances are an indication. Check your address's official category with OneMap's SchoolQuery.

How this distance differs from MOE's

MOE measures in a straight line to the school's land boundary from the address on your child's registration. This site measures from the block to the school's single registered coordinate. A large campus can therefore read as further away here, and a school near the line can fall on either side when MOE measures it. An oversubscribed school still ballots within a band.

Three things this can't know

Your actual floor, facing and renovationPublic data gives a storey band, never your unit.

Leaving it unticked is fine — the tools work either way, and I'll still reply to this enquiry. I don't sell or share your details.
