Bidadari is the Toa Payoh estate built on a former cemetery that, in 2026, produced Singapore's most expensive four-room HDB flats. A 1,043 sq ft unit at Alkaff Lakeview changed hands for $1.368 million in March 2026, roughly $1,311 per square foot. The original BTO buyers paid $433,000 to $550,000 for those same flats back in 2015. That gap is the whole story, and it is also where the money lesson hides. A six-figure paper gain is not the same as six figures in your pocket once CPF accrued interest, cash-over-valuation and selling costs are settled. This guide walks through the actual figures, the lease, the grants and the trade-offs so you can judge whether buying or selling in Bidadari makes financial sense for you.
Bidadari is a 93-hectare estate in central Singapore, administratively part of Toa Payoh and bordered by Upper Serangoon Road. It is a city-fringe location, the band of postcodes just outside the prime central districts that tend to hold their value best. Three MRT stations sit on or near its edge: Woodleigh and Potong Pasir on the North-East Line, and Bartley on the Circle Line. Woodleigh to Dhoby Ghaut takes about 15 minutes, which puts the Orchard belt and the CBD within an easy commute.
The estate name means "angel" in Malay. The land was a Christian and Muslim cemetery from 1908 until burials stopped in 1972, and around 147,000 graves were exhumed from 2006 before housing began. HDB launched the first flats from 2015 and the estate is built out to roughly 10,000 units across the Alkaff, Bartley, Park Edge and Woodleigh precincts. Bidadari Park covers about 10 hectares, Alkaff Lake handles stormwater while recreating a 1930s-era lake, and the area sits next to The Woodleigh Mall and the first underground air-conditioned bus interchange.
For buyers, the premium comes from a stack of durable features: a near-central location, fresh 99-year leases with more than 90 years left, walkable greenery and the kind of amenity density that usually takes a mature town decades to build. If you are weighing this estate against an older one, the BTO vs resale comparison lays out how lease length and price interact.
The headline that made Bidadari famous in finance circles is the four-room resale record. In March 2026, Block 118A Alkaff Crescent (Alkaff Lakeview) sold for $1.368 million, or about $1,311 psf, for a 1,043 sq ft unit on the 10th to 12th floor. That edged past the previous record of $1.336 million ($1,281 psf) set in January 2026 at Block 115C. These were not the only seven-figure deals; sub-$1m and just-over-$1m sales at the same blocks appeared through 2025 as flats crossed their Minimum Occupation Period.
What makes this notable is the starting point. Alkaff Lakeview and Alkaff Vista four-room flats launched in November 2015 at $433,000 to $550,000 and completed around 2019. Sellers reporting gross profits approaching 160 per cent are measuring resale price against that original BTO price. The table below shows how the same blocks moved.
Treat these as record transactions, not the estate average. Million-dollar flats remain a small slice of all Bidadari resales; a typical unit on a lower floor or in a less sought-after stack sells for meaningfully less. If you want to pressure-test what any given price means for your loan, run the figures through the BTO affordability calculator before you fall in love with a listing.
| Project / block | Original BTO (Nov 2015) | Notable resale | PSF | Date |
|---|---|---|---|---|
| Alkaff Lakeview / 118A | $433k-$550k (4-room range) | $1.368m (1,043 sq ft) | $1,311 | Mar 2026 |
| Alkaff Lakeview / 115C | $433k-$550k (4-room range) | $1.336m (1,043 sq ft) | $1,281 | Jan 2026 |
| Alkaff Lakeview / 115C | $433k-$550k (4-room range) | $1.32m (1,043 sq ft) | $1,266 | Dec 2025 |
| Alkaff Lakeview / 118A | $433k-$550k (4-room range) | $1.25m (1,043 sq ft) | $1,206 | Feb 2025 |
| Alkaff Lakeview / 118A | $433k-$550k (4-room range) | $1.0m (1,001 sq ft) | $999 | Apr 2025 |
A 160 per cent gross gain sounds life-changing. The net figure is smaller, and the gap matters. When you buy with CPF, the money you withdraw from your Ordinary Account does not just sit there interest-free. CPF charges 2.5 per cent accrued interest on it, and on resale that principal plus all the accrued interest must go back into your CPF, not your bank account. The longer you held the flat, the larger that refund.
Work a rough example on a flat bought at $500,000 in 2016 and sold at $1.3 million in 2026. Say $300,000 of the purchase used CPF; ten years of accrued interest at 2.5 per cent compounds that to roughly $384,000 that must return to your CPF. You also repay the outstanding mortgage, and the buyer's cash-over-valuation is a one-off that does not repeat for your next home. The cash in hand after the deal is well below the $800,000 paper gain, even if your total net worth still rose. Understand the CPF accrued interest rule before you assume a sale funds your retirement.
There are two ways in, and they suit very different budgets. Buying a Bidadari resale flat means paying today's prices, often four-room flats well north of $900,000 and seven figures at the best blocks, but you move in fast and skip the wait. Buying a Build-To-Order or Sale of Balance flat means a far lower price, the wait, and tighter eligibility, but Bidadari BTO launches are now rare because the estate is nearly fully built out.
Grants change the resale equation more than people expect. A first-timer couple buying a resale flat can tap the CPF Housing Grant and, if income-eligible, the Enhanced CPF Housing Grant of up to $120,000. Bidadari resale prices are high enough that many buyers fall outside the lower income tiers, so check your tier carefully. The Enhanced CPF Housing Grant tiers are based on average gross monthly household income.
On financing, you choose between an HDB loan and a bank loan. HDB's concessionary rate is pegged at 0.1 per cent above the CPF OA rate (so 2.6 per cent as of June 2026) and allows a smaller cash outlay, while bank loans can be cheaper when rates fall but demand a 25 per cent downpayment with at least 5 per cent in cash. The HDB loan vs bank loan comparison breaks down which fits a higher-priced flat like these.
Whichever route you take, size the mortgage against your income, not the asking price. A million-dollar four-room flat is still subject to HDB loan limits and the 30 per cent Mortgage Servicing Ratio, so model the monthly repayment with the mortgage calculator first.
The case for paying up is straightforward: a near-central address, a long remaining lease, mature-town amenities without the mature-town lease decay, and a track record of strong resale demand. For an owner-occupier who plans to stay a decade or more and values the location, the premium can be defensible.
The case against is the opportunity cost. Paying $1.3 million for a four-room flat means a larger loan, more interest over the lease, and a bigger slice of net worth tied up in one illiquid asset in one location. The same budget might buy a larger flat or an executive condominium further out, or leave room to invest. Record prices also tend to attract buyers at the top of a cycle, and HDB resale prices, while resilient, do not rise in a straight line.
A clean way to frame the decision is to compare the all-in monthly cost of a Bidadari resale flat against renting plus investing the difference, or against a cheaper flat in an adjacent estate. If you are open to a non-mature town with newer launches, our look at Bukit Batok as a value estate is a useful counterweight, and the broader HDB BTO flat guide covers the buying process end to end.
Bidadari was a Christian and Muslim cemetery from 1908 until burials stopped in 1972, and about 147,000 graves were exhumed from 2006 before housing began. The history has not held back prices; Bidadari four-room flats set Toa Payoh's resale record at $1.368 million in March 2026, so the market clearly prices the location and lease above any stigma.
Resale four-room flats in the Alkaff precinct have crossed $1.3 million, with a record $1.368 million ($1,311 psf) in March 2026, though those are top-of-market deals and many units sell for less. The original BTO buyers paid $433,000 to $550,000 for four-room flats launched in November 2015, which is the source of the large reported resale gains.
That figure is the gross gain of the resale price over the original BTO price, not cash in hand. After refunding CPF principal plus 2.5 per cent accrued interest, settling the outstanding mortgage, paying agent and legal fees, and buying a replacement home at similar central-region prices, the actual cash a seller pockets is far lower than the headline percentage suggests.
Bidadari is almost fully built out, so new BTO launches there are rare and you would mostly buy resale at today's prices with little wait. Resale buyers pay far more but can use the CPF Housing Grant and Enhanced CPF Housing Grant of up to $120,000 if income-eligible, so the net cost depends heavily on your grant tier and how long you plan to stay.
