From HDB to Condo — Does the Move Actually Work?

Most owners assume they can’t afford it. Most owners haven’t run the numbers. Those are two different things.

The assumption that costs people the most

Here’s a conversation I have most weeks.

“We’d love to upgrade but we can’t afford it.”

Then we sit down, and about half the time it turns out they can. They’ve been comparing the price of the condo against the price of their flat, seen a scary gap, and stopped there.

But that gap isn’t what you need in cash. What you need is the answer to a longer question.

What actually decides it

What your flat is worth today. Including the CPF you’ve used plus accrued interest, because that has to be returned when you sell.

What your outstanding loan is. And what it costs you to clear it.

What you can borrow for the next one. This is where most people undershoot. Your loan limit depends on income, age and existing commitments — and the rules are different when you already own a flat.

What you need in cash. Down payment, stamp duties, legal fees, and the gap between what you sell for and what you buy.

What your monthly payment becomes. The number that actually determines whether this is comfortable or a slow squeeze.

Put those together and you get a real answer. Usually it’s “not yet, and here’s what would change that” or “yes, and here’s the sequence”.

Sell first or buy first?

This is the question that keeps people awake, and there’s no single answer.

Sell first, then buy. You know exactly what you have to spend, and you’re not carrying two loans. The risk is a gap between leaving and moving in — and if you have children in school or a flat full of furniture, that gap is a real cost.

Buy first, then sell. You avoid the gap. But you need to qualify for the second loan while still carrying the first, and you’re exposed if your flat takes longer to sell than you planned.

For most HDB upgraders, selling first with a well-timed option period is the safer sequence — and the timing can be managed so you’re not homeless. That’s a planning problem, not a lucky-guess problem, and it’s the part I spend the most time on.

“We had no intention of selling at first, and we were not clear whether we could even afford a bigger place — we assumed a larger home would simply cost more. Perry did the math for us and showed us that the move was actually very feasible. They then mapped out the whole sequence for us, selling first and buying second… Most importantly, they timed the selling and buying so there was never a gap — as a family of six, we would otherwise have had no house to move to.”

What changes after your MOP

Once you’ve served your Minimum Occupation Period, your HDB flat becomes sellable on the open market, and that’s when upgrading becomes possible.

Two things to check before you plan anything:

Your MOP date. Not the month you think you moved in — the date HDB counts. Getting this wrong invalidates the whole plan.

Resale levy, if you’re buying another subsidised flat. It applies when a second subsidised flat is bought. It does not apply if you’re moving to a private condo, which catches people out in both directions.

The honest version

An upgrade is not automatically a good idea. It’s a leveraged bet on a larger asset, and it makes sense when your income is stable, your time horizon is long, and the numbers leave you comfortable rather than stretched.

I’ve told clients to wait. I’ve told them their current flat was the better asset. I’ll tell you the same thing if that’s what your numbers say.

What I won’t do is let you decide based on a guess, in either direction.
