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.

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 HOUGANG, not here.

HOUGANG, typical block+8.9%

Middle of 30 blocks in HOUGANG that clear the bar — half fall between +5.5% and +12%. 2 came out negative — high floors sold for less in 2 of them.

Every band in HOUGANG, 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

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.
