The distance rule that made addresses within 1km of a popular school expensive has been reworked, and property commentators spent last week reassessing whether that premium is still worth paying (Straits Times, 11 September 2026). The useful answer depends on a figure most parents never calculate: what the premium costs per month once it sits inside a mortgage.
What the distance rule actually does
Primary 1 registration has long ranked applicants by home-to-school distance in tiers: within 1km, between 1km and 2km, and beyond 2km. Distance does not admit your child. It decides the order in which categories of applicants are considered, and when a phase receives more applicants than there are places, balloting decides who gets in within that tier. That combination, priority plus ballot risk, is what created an observable price and rental premium inside 1km catchments rather than a gentle gradient across the map.
The change now widens the band of addresses that give a family a workable chance, which is why analysts quoted by the Straits Times expect demand near popular schools to stay firm rather than collapse. Proximity still carries priority and it still carries the daily convenience of a 10-minute walk. What shrinks is the cliff edge at the 1km boundary. Check your specific school's phase-by-phase intake and ballot history with MOE before you price anything, because a widened band is only valuable if that band was not already oversubscribed.
The table below sets out how each band typically behaves, what housing stock sits there around a mature-estate popular school, and the premium buyers have historically paid for it.
| Distance band | Priority and ballot treatment | Typical stock around a popular school | Historical premium paid |
|---|
| Within 1km | Highest distance priority; ballot if the phase is oversubscribed | Newer condos, prime HDB blocks in the immediate estate | Largest, visible in both resale price and rent |
| 1km to 2km | Considered after the 1km group; ballot risk depends on places left | Older leasehold condos, HDB blocks in adjacent estates | Modest, often within normal estate-to-estate variation |
| Beyond 2km | Lowest distance priority | Full open market across the region | None attributable to the school |
The takeaway: the money has always been concentrated in the first band, so the decision is whether you still need to be in it.
What the premium costs per month
Take two comparable resale units, one inside the 1km radius at S$1.60m and one 1.5km out at S$1.45m. All figures here are illustrative: 75% loan-to-value (LTV), a 25-year tenure and a bank rate of 3.0% per annum held flat for the calculation.
Loan quantum at 75% LTV is S$1,200,000 on the closer unit and S$1,087,500 on the further one, a gap of S$112,500. At 3.0% over 300 months, the monthly instalments are S$5,690 and S$5,157 respectively. The premium therefore costs S$533 a month, or S$6,396 a year.
The upfront gap is larger in proportion. The 25% down payment is S$400,000 against S$362,500, a difference of S$37,500. Buyer's stamp duty (BSD) on S$1.60m is S$49,600 against S$42,600 on S$1.45m, adding S$7,000. Total additional cash and CPF at purchase: S$44,500.
That gap is also a borrowing question. A S$112,500 smaller loan frees roughly S$533 a month of total debt servicing ratio (TDSR) headroom, which can be the difference between a workable approval and a rejected one for a household with a car loan or an existing property. If the widened catchment genuinely lets you buy 1.5km out, test the cheaper option against your borrowing capacity first, because the school premium is competing with your loan eligibility, not just your budget.
Renting in, rather than buying in
Renting inside the catchment for the registration year has been the standard workaround, and it is worth pricing against the numbers above. At an illustrative S$4,500 a month for an in-catchment three-bedder, a year costs S$54,000 plus agent fees and two moves. That is eight and a half times the annual instalment difference between the two purchase options.
Renting also carries a constraint buyers do not always price: MOE has required parents to maintain the registered address for at least 30 months from the start of the registration exercise, so a 12-month lease used purely for priority is not the clean, short commitment it appears to be. Confirm the current condition directly before you sign anything.
Before you bid
Re-price your shortlist with the 1km boundary treated as a preference rather than a gate. Pull the school's recent phase and ballot data, then ask whether S$44,500 upfront and S$533 a month buys a materially better admission chance or just a shorter walk. If it is the walk, that is a legitimate thing to pay for. It is just a much smaller number than S$150,000 of purchase price.
