HDB Upgrader Guide: From a Hougang HDB Flat to LinkTown Residences
Selling a Hougang HDB flat to buy at LinkTown Residences? What your flat may fetch, a worked cash and CPF example, sell-first vs buy-first, the ABSD refund rule and a timeline to completion.
For many Hougang families, LinkTown Residences (Hougang Central Residences) is the obvious upgrade: a new private home at the centre of the town they already live in, directly linked to Hougang MRT and a new mall. This guide walks through the numbers an HDB upgrader typically needs to check, using illustrative figures. Prices are not yet announced, so treat every number here as an estimate.
Step 1: what your HDB flat might fetch
According to HDB resale data reported for January to September 2026, the median resale price in Hougang was about:
- S$619k4-room medianHougang, Jan–Sep 2026
- S$775k5-room medianHougang, Jan–Sep 2026
Your actual price depends on the block, floor, remaining lease, renovation and how close you are to the MRT. What matters for upgrading is not the sale price but your net proceeds: sale price, minus the outstanding HDB or bank loan, with the CPF you used (plus accrued interest) going back into your CPF Ordinary Account. That refunded CPF can then be used for the condo, subject to CPF limits.
Step 2: the cash and CPF you’ll need
Take a 3-bedroom of about 1,066 sq ft (indicative size, not official). At an estimated S$2,500 psf, that is S$2,665,000.
| Item | Working | Approx. amount |
|---|---|---|
| Purchase price | 1,066 sq ft × S$2,500 | S$2,665,000 |
| Down payment (25%, first housing loan) | 25% × S$2,665,000 | S$666,250 |
| … of which minimum cash (5%) | 5% × S$2,665,000 | S$133,250 |
| … balance (20%), cash or CPF | 20% × S$2,665,000 | S$533,000 |
| Buyer’s Stamp Duty | By tiers (see below) | S$102,850 |
| Bank loan (75%) | 75% × S$2,665,000 | S$1,998,750, subject to TDSR |
| ABSD if you still own the HDB flat (SC, 20%) | 20% × S$2,665,000 | S$533,000 |
BSD working: the first S$1,500,000 attracts S$44,600 (S$1,800 + S$3,600 + S$19,200 + S$20,000). The remaining S$1,165,000 is taxed at 5%, which is S$58,250. Total: S$102,850. See our full stamp duty guide for other unit sizes.
A simple illustration
Suppose a couple sells a 5-room flat at the S$775,000 median, with a hypothetical S$150,000 loan outstanding. Their net proceeds are S$625,000 (part of it returns to CPF). Against an upfront need of S$769,100 (S$666,250 down payment plus S$102,850 BSD, before legal fees), they would need roughly another S$144,100 from savings or existing CPF balances. Your own figures will differ, which is why a proper CPF and loan check matters.
Can you get the loan?
Banks assess the Total Debt Servicing Ratio (TDSR) of 55% using a stress-test rate of 4% for private property. As a rough guide, a S$1,998,750 loan over 30 years at 4% works out to about S$9,540 a month, which needs a combined gross monthly income of roughly S$17,350 if you have no other debts. Loan tenure is also capped by age, so older borrowers may need a smaller loan or larger down payment. Try your own numbers in our loan calculator.
What if you own a 4-room flat?
A smaller unit may be the more comfortable step up. A 2-bedroom of about 678 sq ft at the same estimated S$2,500 psf is about S$1,695,000. The 25% down payment is S$423,750 (at least S$84,750 in cash) and BSD is S$54,350, so about S$478,100 is needed upfront before legal fees. Selling a 4-room at the S$619,000 median with a hypothetical S$150,000 loan left would release about S$469,000, leaving a gap of roughly S$9,100 to top up from savings or CPF. The 75% loan of S$1,271,250 works out to about S$6,070 a month at the 4% stress rate over 30 years, needing roughly S$11,040 of monthly household income with no other debts.
Other costs to budget for
- Legal fees for both the sale of your flat and the condo purchase.
- Agent commission on your HDB sale, if you use one.
- Rent or moving costs if you sell first.
- Renovation, furniture and maintenance fees once the condo completes (fees for this project are not yet announced).
Step 3: sell first, or buy first?
Sell first, then buy
- No ABSD, because you own no property when you buy
- Sale proceeds and refunded CPF are ready for the down payment
- But you need somewhere to stay until the condo completes, expected around 2030 to 2031, which can mean years of rent or moving in with family
- Timing risk: if the condo launch slips or the unit you want sells out, you have already sold
Buy first, then sell
- Stay in your flat throughout construction
- Pay 20% ABSD upfront as Singapore Citizens (S$533,000 in our example), within 14 days of signing
- Married couples with at least one Singapore Citizen can apply for a refund if the flat is sold within the IRAS time limit, generally six months after the condo’s TOP or CSC, whichever is earlier
- You carry both properties for a while, and the loan limit may drop to 45% if you still have an outstanding housing loan
Because LinkTown Residences is uncompleted, the progressive payment scheme spreads the loan drawdown over the build. That makes buy-first workable for many families, as long as you can fund the ABSD upfront and the bank is comfortable with your loan. Check whether your existing HDB loan affects your LTV before you commit.
MOP: the first thing to check
HDB owners can only buy private property after their flat has met its Minimum Occupation Period (MOP), usually five years. If your MOP falls after the sales launch, expected in early 2027 (UOL’s August 2026 results guide a 2H 2027 launch), you cannot buy first and would need to wait or plan a later purchase. Check your exact MOP date on the HDB portal.
A sample timeline around a ~2030/31 completion
| When | Buy-first path | Sell-first path |
|---|---|---|
| Now to launch | Check MOP, CPF, get in-principle approval | List flat, line up interim housing |
| Launch (expected early 2027) | Book unit; pay 5% at OTP | Book unit using sale proceeds |
| ~8 weeks later | Sign S&P, pay 15%; BSD and ABSD within 14 days | Sign S&P, pay 15%; BSD only |
| Construction years | Live in HDB flat; progress payments begin | Rent or stay with family |
| TOP (expected ~2030/31) | Sell flat within the refund window, claim ABSD refund | Collect keys and move in |
The exact TOP date is not announced. Keep a buffer: HDB resale transactions take time, and you want your flat sold comfortably within the six-month window.
