Case Study: From Punggol 5-Room to a $1.75M Condo. A Couple's Sell-First Timeline, Dollar by Dollar

Expert takeaway: For a Punggol 5-room household upgrading to a $1.75M condo in 2026, selling first is what keeps the deal clean. It preserves the 75% loan-to-value limit, sidesteps the 20% ABSD trap, and frees up genuine cash. The hard part is not the price. It is the sequencing.

The couple who wanted to upgrade without gambling

Daniel and Hui Min bought their 5-room flat along Punggol Field in 2016, moved in after their keys were collected, and cleared their Minimum Occupation Period years ago. By early 2026, with two children and a hybrid work routine that meant one of them was always home, the flat felt tight. They wanted a private condo with a study and a gym downstairs, and they had their eye on the $1.7M to $1.8M band in the Outside Central Region.

What they did not want was to make an expensive mistake. They had read that upgrading badly can quietly cost six figures in stamp duty and financing. So before they queued at any showflat, they mapped out the numbers, dollar by dollar. This is the post-MOP upgrade sequencing that most households get wrong, and getting it right was the whole game.

What was actually happening in the 2026 market

The backdrop mattered. The market they were selling into and buying in was cooling, but gently. URA flash estimates showed private residential prices rose 0.5% quarter-on-quarter in Q2 2026, easing from 0.9% in Q1, with the non-landed segment slipping 0.1%. On the public housing side, the HDB Resale Price Index dipped 0.3% in Q2 2026, its second consecutive quarterly decline in nearly seven years.

That combination is unusual. It meant Daniel and Hui Min were selling into a slightly softer HDB market while buying into a private market that was still nudging up, but slowly. In Punggol specifically, 5-room flats were transacting around a median of the mid-$700,000s in the first half of 2026, with the occasional record-breaker crossing the million-dollar mark near Punggol MRT and Waterway Point. Their unit was mid-floor, unblocked, and well kept but not a top-floor showpiece, so they priced realistically rather than chasing headlines.

The sequencing decision: sell first or buy first

This is the fork in the road for every HDB upgrader. Buying the condo first would have meant, at the point of purchase, that they still owned the HDB flat. That triggers two problems. First, the second residential property attracts Additional Buyer's Stamp Duty of 20% for a Singapore Citizen's second property. On a $1.75M purchase, that is $350,000 in ABSD alone. Second, owning two properties would have pushed them out of the top loan-to-value bracket, cutting their maximum loan and demanding far more cash upfront.

Selling first solved both. By completing the HDB sale before, or close to, the condo purchase, they remained first-time private buyers for LTV purposes, kept the 75% loan ceiling, and paid zero ABSD. The trade-off is timing risk: sell too early and you have nowhere to live, sell too late and you scramble. The couple decided the tax and financing savings were worth managing that risk carefully. Our guide on upgrading from HDB to condo without paying ABSD walks through the same logic in detail.

The Punggol sale, dollar by dollar

They listed at $775,000 and, after two months and a handful of viewings, accepted $760,000 from a young family. That is roughly in line with where mid-floor Punggol 5-room units were clearing in 2026. The gross sale price is only the start. What lands in your pocket is what is left after the outstanding loan and the CPF refund.

The CPF refund was the figure that surprised them most. The $228,000 did not vanish. It went back into their CPF Ordinary Accounts, principal plus the accrued interest they would otherwise have earned. But it is not free cash for the condo down payment unless they choose to redeploy CPF again. This is exactly the shock we describe in HDB sale proceeds explained: the number on the caveat is not the number in your bank account.

Funding the $1.75M condo

They chose a 3-bedroom OCR unit at $1,750,000. Under the 75% LTV limit, the maximum bank loan was $1,312,500, leaving $437,500 as the required down payment, of which at least 5% ($87,500) must be paid in cash and the rest can come from cash or CPF.

The Buyer's Stamp Duty on $1.75M works out to roughly $56,600 under the current tiered schedule. Add legals and renovation, and their upfront requirement before the loan was about $577,100. Against that, they had $491,600 in cash proceeds plus the $228,000 refunded to CPF. By using CPF for part of the down payment and topping up with cash, the numbers closed with a buffer. You can model your own version of this with our affordability calculator and confirm the duty using the stamp duty calculator.

On the monthly repayment: at a bank rate of around 2.5% over a 28-year tenure, the $1,312,500 loan costs roughly $5,900 a month. Their combined income comfortably kept them within the 55% TDSR ceiling, but they stress-tested it at the notional 4% floor rate that banks apply, not at today's rate.

The move: how they avoided a bridging loan

The elegant part of their execution was the timeline. Rather than sell, move into a rental, then buy, they negotiated. On the HDB sale they requested an extended completion. On the condo purchase, a resale unit, they negotiated a completion date roughly ten weeks out. The two timelines overlapped just enough that they moved once, directly from Punggol to the new condo, with no interim rental and no bridging loan.

Had the timelines not lined up, a bridging loan was their fallback, but they preferred to avoid the extra interest. The lesson: negotiate completion dates as hard as you negotiate price.

Opportunities and risks they weighed

The opportunity was clear. Selling into a cooling HDB market was slightly against them, but buying into an OCR non-landed segment that had just softened 0.1% meant they were not overpaying at a peak. The wider set of choices from the roughly 13,000-plus flats reaching MOP in 2026 gave buyers, including their own buyer, more room, but it also meant the couple had to price their own flat sharply to sell within two months.

The risks were real. A sell-first strategy leaves you exposed if you cannot find a suitable replacement in time, which can force a rushed purchase or a temporary rental. Interest rate movements over a 28-year loan could lift their monthly repayment. And in a flat-to-softening private market, they should not expect quick capital appreciation; this is a home-first decision, not a flip. If you are weighing the same move, our take on the private versus HDB divergence is worth reading before you commit.

The transferable framework

Strip away the names and the framework is simple, and you can apply it to any HDB-to-condo upgrade:

• Sequence to protect ABSD and LTV. Sell first, or structure completions so you do not own two homes at the point of purchase. This one decision saved them $350,000 in ABSD and preserved the 75% loan ceiling.
• Calculate cash, not caveat. Deduct the outstanding loan and the full CPF refund with accrued interest before you believe any headline sale price.
• Negotiate completion dates as hard as price. Overlapping windows let you move once and skip bridging costs.
• Stress-test at the floor rate. Qualify your loan at the notional 4% used for TDSR, not at today's promotional rate.
• Buffer for BSD and renovation. These are the line items upgraders most often underestimate.

What would they do differently? They admit they budgeted $80,000 for renovation and quietly went over by close to $18,000 on built-in carpentry and an aircon reconfiguration. They also underestimated how much of their proceeds would be locked back into CPF rather than sitting as spendable cash. Next time, they said, they would hold a larger cash buffer and treat the renovation quote as a floor, not a ceiling.

Every upgrade turns on a handful of numbers that are specific to your flat, your CPF balances, and your income, and small missteps in sequencing can cost far more than any price negotiation.
