Should I Sell My HDB Before Buying A Condo?

This is the question I am asked most often, and it does not have a universal answer. What it has is a decision rule.

Start with the question underneath the question

When someone asks whether to sell first, what they usually mean is: how do I do this without ending up exposed?

So the useful framing is not which sequence is better in the abstract. It is which sequence leaves you solvent and unhurried if things go slightly wrong — because in a transaction with this many moving parts, something usually does.

What selling first actually gives you

You know your number. The flat is sold, the loan is repaid, the CPF refund has gone back, and you are looking at an actual bank balance rather than an estimate. Every property you view is assessed against a real budget.

You are also, in most cases, buying as a household that does not own another residential property at the point of purchase — which keeps ABSD out of the picture and keeps your new loan treated as a first housing loan.

The cost is practical rather than financial. Your flat's completion and your new home's completion rarely align neatly, so you may need somewhere to live in between. That means either an interim rental, a stay with family, or negotiating to lease back your old flat from the buyer for a short period — which is sometimes possible and sometimes not.

What buying first actually gives you

One move. You secure the property you want, at a price you have seen, without a clock running.

That is worth something real, particularly for households with school-going children or anyone who genuinely cannot face moving twice.

The costs are concentrated at the start. You will be holding two residential properties at the moment of purchase, which means ABSD is payable upfront on the new purchase. For married couples with at least one Singapore Citizen spouse, a remission may be claimable if the first property is sold within the prescribed window — but the money leaves your account first and comes back later, and the conditions have to be met exactly.

Your loan-to-value limit on the new purchase is also lower while the existing housing loan is outstanding, which means more cash and CPF upfront.

The decision, as a path

An illustrative example

A couple owns a flat they believe will sell for $700,000. They still owe $180,000 on the loan. Between them they have used $220,000 of CPF, and accrued interest has built up to roughly $60,000 on top of that. Selling costs come to about $15,000.

Working it through: $700,000 less the $180,000 loan leaves $520,000. Refunding $280,000 to CPF leaves $240,000. After selling costs, they have about $225,000 of cash, plus $280,000 sitting in CPF available for the next purchase.

That is a strong position. But notice how different $225,000 of cash is from the $700,000 sale price they had in their heads — and notice that the CPF portion, while usable, is not cash for stamp duty flexibility or renovation.

This is the single most common gap between what upgraders expect and what they find.

What I would actually ask you

If you came to me with this question, I would want to know four things before offering a view:

1. What is your cash buffer after the upgrade, not before it?
2. How stable are both incomes over the next three years?
3. Is there a hard deadline — a school placement, a lease expiring, a family situation?
4. If the market moved against you by ten per cent between your purchase and your sale, would that be an inconvenience or a crisis?

The fourth question decides it more often than the first three.
