On balance, Castle Green points up.
Strong track record, sitting inside Woodlands Regional Centre — the fundamentals buyers pay up for are here.
Why it's pushing up
What matters most for you
- Convenient — MRT about 7 min on foot; 1 food & retail spot nearby.
- Rentable — ~3.3% gross yield; transport and schools nearby keep tenants coming.
And what makes it better
- Every unit type has risen — 3-bed +43.8%, 4-bed +35.3% since 2021.
- A Primary-1 priority school within 1km — a real family draw.
What's holding it back
- Leasehold, ~66 years left — the lease clock weighs on price and financing the older it gets.
- Its recent +6.2%/yr rode a hot cycle — don't bank on that pace repeating.
- The market's near the top of its cycle — mind your entry price.

If you’re buying
≤ $1.26M
Aim at the middle or below. A patient buyer has been getting closer to $1.22M.
If you’re selling
~$1.32M
List at the top of fair; realistic close is $1.26M–$1.28M unless it’s a high floor.
Why no rush either way: Seller’s Stamp Duty means a buyer can’t sell penalty-free for ~4 years — so you’re holding regardless. That’s your leverage to negotiate down now, not overpay.
The reality check — does the gain even make sense?
Our blunt read: ~$1.04M over 10 years at this project’s own pace. It works — but forward from a cycle top, treat it as a maybe, not a promise. This is our own POV, not a forecast — the pace is the project’s own (~6.2%/yr), and past pace never promises the future.

If you’re buying — the outlook
Castle Green
Outside Central Region (OCR) · District 26 · ~$1,375 psf · 3.3% yield
Prices are near the top of the cycle, and the government is still cooling it — but cheap loans, steady immigration and rising rents are holding them up. For Castle Green, its own prices are still climbing. Over a 4-year hold, expect modest growth — not a big jump.
On balance, the wind is leaning to your favour.
What it means for you: At ~$1,375 psf, Castle Green is priced below similar new projects nearby — good value against its peers. Its own prices are still climbing (~6.2%/yr over ~5 years). The real watch-out: about 3,789 brand-new units come up for sale in this district by 2026 — direct competition for when you sell. Buying near the top of the cycle just as that lands can cap your gains. So — use the incoming supply as your reason to negotiate the price down now, don't overpay, and plan to hold past the 4-year stamp-duty window before selling.
The signals behind it
Dots show how much weight each one carries.
Holds prices back
Prices are near the top — up 33% in 5 years, well above the 4.6%/year long-run pace. Less room left to climb.
Supports prices
Castle Green's own prices are still climbing — about +5% in the latest year of sales.
Holds prices back
The suburbs (OCR) grew fastest since 2004 — a lot of that gain is already in, so there's more risk it cools from here.
Holds prices back
The government is still cooling the market — the latest was SSD back to 4 years at 16/12/8/4% (2025). That caps how fast prices can run.
Supports prices
Loan rates are cheap right now (~1.08%) and falling. Easy to carry — which supports prices, but also means more buyers competing with you.
Supports prices
Against salaries, prices aren't expensive by past standards — people can still afford to buy.
Supports prices
Lots of new people keep moving to Singapore (non-residents up ~16% over 5 years) — steady demand for homes and rentals.
Holds prices back
About 3,789 new units are still unsold in this district, with the first big batch finishing around 2026 — plenty of fresh supply that can hold prices and rents back.
Supports prices
New launches in this district are selling well — 6 recent ones are around 100% sold, so buyer demand here is healthy right now.
Holds prices back · small effect
The government keeps releasing a lot of new land (~9,200 units this half-year) — more future supply that can weigh on prices years down the road.
About neutral · small effect
Foreign buyers are almost gone since the 60% tax (~1.4% of buyers), but the suburbs never leaned on them — so it barely affects you here.
Supports prices
Rents at Castle Green are up ~5% over the last couple of years — good if you're renting it out.
Supports prices · small effect
There's more CPF money sitting ready to put toward a home than a few years back — a small support in the background.
Supports prices · small effect
The economy is growing (5% last year) and jobs are steady (1.9% unemployment) — no alarm bells.
Supports prices · small effect
Building costs are high (up ~39% since 2010) and still creeping up — developers can't build cheap, which puts a floor under new-launch prices.
Built from real public data (URA price index back to 1975, plus rates, immigration, rents, the economy). It prepares you — it never promises a price.
How far could it go — and when?
Is the price high? ~$1,375 psf is ~38% below similar nearby projects (~$2,203). good value
(The whole suburbs average is ~$1,534 psf — but that lumps in older stock, so we compare like with like, not against that.)
What’s realistic here? Its own record and its real neighbours — not the market.
Castle Green has grown ~6.2%/yr over ~5 years. Similar nearby: Springleaf Residence -0.8%, Lentor Modern 4.2%, Lentor Hills Residences 3.6%, Lentor Mansion -0.4%, Hillock Green 6.6% — a -0.8–6.6%/yr spread (most around 3.6%).
You can’t sell for ~4 years without a penalty. Seller’s Stamp Duty is 16/12/8/4% in years 1–4, then 0% — so the honest question is what happens from year 4 on.
