Buying near a school: what the 1km rule is really worth

What distance actually buys you

Primary One registration runs in phases, and home-to-school distance decides who wins a place when a phase is oversubscribed. Applicants living within one kilometre are drawn first, then those between one and two kilometres, then those beyond. Within each band, citizens are drawn ahead of permanent residents.

So distance is not a scoring system where closer is steadily better. It is a set of bands, and the only thing that matters is which band you fall in. A home eight hundred metres away and one nine hundred metres away are identical for balloting purposes. A home at one thousand and fifty metres is in a different queue entirely.

The distance is measured by the authorities from the school to the residential address as a straight line, not by walking route or driving time. This is the detail that most often surprises buyers: a property that feels near, across a canal or an expressway with a long detour to the gate, can sit comfortably inside the ring — and one that feels close along a short walk can fall outside it.

Why the premium exists, and why it grew

Two things changed at once. On the demand side, admission rules were adjusted to reserve more places in the open phase — the one for families with no alumni tie and no volunteering history. The intent was to widen access, and it did. It also lengthened the queue almost everywhere else: families who would previously not have applied now do, and families who once felt safe through an alumni or volunteer route increasingly find themselves balloting alongside everyone else.

When balloting tightens, being inside the one-kilometre ring stops being an advantage and becomes something closer to a requirement. Demand concentrates into a fixed and very small set of addresses.

On the supply side, almost nothing new gets built inside those rings. Established schools sit in established estates where land was spoken for decades ago. Recent studies of resale prices near sought-after primary schools have found homes within a kilometre outpacing their own districts by several percentage points over a four-year window, and in the strongest cases by more than fifteen — with new-launch supply near those same schools collapsing to a small fraction of what it was. Fixed supply against rising demand does what it always does.

Three reasons the premium is smaller than it looks

First: you are buying a distance, not a place. If the purchase is justified by a ballot, the value of the address concentrates into a few years around registration, and your eventual buyer is another family doing the same thing. That is a real pool but a narrow one, and it prices the home against a use rather than against the wider market — which is exactly the sort of demand that thins when the rules move.

Second: the boundary is a hard edge and you are paying at the edge. The premium is priced into homes inside the ring by sellers who know precisely where the line runs. You are rarely buying an underpriced asset; you are buying a correctly-priced one whose price includes the thing you came for. The gain accrues to whoever owned it before the rules tightened.

Third, and most important: a premium built on an admission rule is exposed to that rule. Registration phases have been adjusted before and will be again, and the stated policy direction has for years been that every school is a good school. Perceptions have not moved much. But a price supported by an allocation formula is different in kind from one supported by an MRT station or a sea view, and it should be held with that in mind.

What to check before you pay for the address

Measure the actual distance, from the actual unit, using the official school-finder tool rather than a map app or an agent's description. Straight-line distance to a school boundary is not what a route planner returns, and being wrong here costs the entire premium you paid.

Check the phase you would actually be applying in. A family with an alumni connection, or one prepared to volunteer, enters earlier and may not need the distance at all — in which case the premium buys nothing. The households for whom the ring genuinely matters are those entering in the open phase with no other tie.

Check how oversubscribed the school has actually been in the phase that applies to you, in recent years. Some popular schools clear without balloting in phases where the queue is shorter than the reputation suggests. A premium paid to win a ballot that would not have happened is a premium paid for nothing.

And check the exit. Ask who buys this home in eight years if the rules change or the school falls out of fashion — because that question, not the entry price, is the one that decides whether the premium was an investment or a fee.

The honest framing

If the school is genuinely why you are moving, the numbers say the premium has been real and has been widening, and the supply position that produced it is not resolving. That is a defensible reason to pay it, provided you have measured the distance properly and know which phase you are in.

If the school is a justification for a purchase you wanted to make anyway, be honest about it — because you will pay the premium either way, and only one of those two cases has a reasonable chance of getting it back.

Either way the rest of the arithmetic does not change. Total debt servicing is still capped at 55% of gross income, a loan on a flat at 30%, and both are tested at the higher of your package and a statutory floor of 4% rather than at the rate you will actually pay. The school decides the postcode. It does not move the affordability test by a dollar.

Common questions

How is the 1km distance to a school measured?

As a straight line from the school to the residential address, not by walking route or driving distance. A home that feels near but sits across a canal or expressway can still be inside the ring, and one a short walk away can fall outside it — so measure with the official school-finder tool rather than a map app.

Does living closer than 1km improve my chances further?

No. Distance works in bands, not as a sliding scale: within 1km, then 1-2km, then beyond. Eight hundred metres and nine hundred metres are identical for balloting. Only crossing a band boundary changes anything.

Is a home near a popular school worth more?

Recent studies of resale prices found homes within a kilometre of sought-after primary schools outpacing their own districts by several percentage points over four years, and in the strongest cases by considerably more — driven by tighter balloting and almost no new supply inside those rings. The premium is real, but it is already in the asking price.

What is the risk in paying a school premium?

It rests on an admission rule rather than on a physical amenity. Registration phases have been adjusted before, the official position is that every school is a good school, and your eventual buyer is likely another family in the same situation — a narrower pool than the general market.
