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 KALLANG/WHAMPOA, not here.

KALLANG/WHAMPOA, typical block+10.6%

Middle of 21 blocks in KALLANG/WHAMPOA that clear the bar — half fall between +6.3% and +13.8%. 2 came out negative — high floors sold for less in 2 of them.

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

What's around

Straight-line distance from the building — the walk is longer, and how much longer depends on what is in the way.

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

  1. Your actual floor, facing and renovationPublic data gives a storey band, never your unit.
  2. Whether you sell or buy firstChanges your ABSD, timeline and bridging cost — often by five figures.
  3. Your real CPF accrued interestThe figure here is an estimate. Yours is in your CPF statement right now.

Tell me those and I'll run your actual numbers — no charge, no obligation.

Optional — but it's the single biggest thing the public data can't see.

What are you weighing up?
Rough timing
Staying in touch — optional

Leave it unticked and the form still sends — you get the reply to what you asked, at the address you gave, and nothing after it. This form asks for no phone number and stores none.

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.
