Fair case on the numbers
Confidence: medium, some figures missing (67% of the weight known)
Adds up the measurable lines below: price against comparable homes, rental yield, the lease, how nearby prices moved, MRT distance and competing supply. 65 or more is a strong case on the numbers, 45 to 64 fair, under 45 weak. It leaves out what only you can judge (layout, school, the view) and is not a valuation or advice.

This condo's median price per sq ft (its own 3 resales in the last 12 months) against resale condos and apartments within 1.5 km, sold in the last 12 months, any size. Each resale price is scaled to this condo's lease.

What it compares
Each of this condo's own resales (its own 3 resales in the last 12 months) against resales in other existing condos in the same town (URA planning area) of a similar size (within 20%), sold in the same period, each scaled to this condo's lease, and to its building age (completed 1988) where the other condo's completion year is known.The figures
- This condo: S$1,677 psf
- 3 of its 3 own sales are each compared with the median of sales of a similar size in 22 other existing condos in Bishan. The gap is the median of these per-sale gaps; S$1,735 psf is the town price that gap implies.
- Age adjustment: 22 of the 22 other condos are also scaled to this condo's age (completed 1988), about 0.9% per year of difference.
- In your favour when 10% or more below the typical price; watch out when 10% or more above.
How fair is this comparison?
A rough guide only. Same town, lease and building age adjusted, each sale against homes of its own size; but condition and distances to the MRT differ within a town.What this check cannot see
- Building age is adjusted at one average rate, about 0.9% a year (measured from 10,793 private resales in 1,531 condos, Oct 2025 to Oct 2026). Real prices fall faster in a building's first 15 years and slower after, faster for 99-year leases than freehold, and upkeep differs between buildings.
Can it earn or hold its value?
Rental yield · Watch out
About 2.4% of the price a year in rent, before costs
Less than the typical 3.2% for existing condos, so rent would cover less of your costs.

What it compares
Rents of condos and apartments of similar size within 1.5 km (URA rental contracts, last 4 quarters), per sq ft, × 12, against this condo's price per sq ft.The figures
- Nearby rent: S$3.38 per sq ft a month, median of 178 contracts (URA, Q1 2026 to Q3 2026)
- Yield = S$3.38 × 12 ÷ S$1,677 psf = 2.4%. In your favour when 0.3 percentage points or more above the typical yield; watch out when 0.3 or more below.
How fair is this comparison?
Fair. Rents of similar homes nearby, not of this condo.What this check cannot see
- Gross yield: property tax, maintenance fees, agent fees and empty months usually take 1 to 2 percentage points off.
- URA records rented sizes as ranges (for example 900–1,000 sq ft); PropGPT uses the middle.
- Building age is not adjusted: a 25-year-old condo and a 3-year-old one count the same, so part of any gap is simply new against old.
Lease · In your favour
Freehold
No lease runs down, so the home does not lose value as the years pass. Buyers usually pay more for this.

Very fair. A fact about this home.What this check cannot see
- Freehold land does not protect the building: it still ages, and an en bloc sale needs most owners to agree.

- THE GARDENS AT BISHAN (982 m): +28% from 2022-Q2 to 2026-Q2; market +21%
- In your favour when 60% or more of nearby projects beat the market; watch out at 40% or fewer.
How fair is this comparison?
A rough guide only. Each project against itself over time, so like for like within a project; but the projects are not this one.What this check cannot see
- PropGPT's sales data starts in October 2021, so an older project's 'first year' is a resale year, not its launch.
- A project's early sales may be small units and later ones large, or the other way round.
- Past price moves do not predict future ones.

- Stamp duty on S$2.20M: S$79,600 (assumes a Singapore citizen buying a first home)
- Selling within 4 years of buying costs seller's stamp duty of 16% falling to 4%; buying now, that ends around Nov 2030.
- A completed home: the full loan starts at once, and a buyer's agent fee (often 1%) is usual if you use one.
