Right-Sizing and Selling in Singapore: Sell and Buy Without Two Mortgages

Right-Sizing Explained: More Suitable, Not Just Smaller

People hear right-sizing and assume it means downsizing. It doesn't. Downsizing is one type of right-sizing. This is when the kids have moved out and a five-room flat feels too big to clean. But right-sizing also covers a young family in a two-room condo who needs more space fast. It also applies to a couple who wants to move from a high-floor unit to something with lift access for ageing parents. The word that matters here is suitable, not small.

I see this every week. A client calls thinking they need to downsize. After we talk through their next five years, they need to move sideways, same size, different layout. So the first question I ask isn't how big your current place is. It's what your life looks like in three years.

• Empty nesters holding onto rooms they no longer use
• Growing families outgrowing their current unit
• Owners wanting single-level living instead of stairs
• Households consolidating two properties into one
• Owners relocating for work, family, or lease timing

Once you know which of these describes you, the next decision, sell first or buy first, gets a lot clearer.

MOP and Wait-Out Period Checks Before You List

Before we talk price or timeline, I check one thing first. Have you hit your Minimum Occupation Period, or MOP? For most HDB flats, MOP is five years from the day you collect your keys. Sell before that and you legally can't, full stop.

There's a second check that trips people up more: the wait-out period. If you or your spouse previously owned private property and sold it, you may need to wait out a period before buying a resale HDB flat.

• MOP status confirmed against your lease start date, not the date you moved in
• Whether you or your spouse have owned or held interest in private property recently
• CPF usage on your current flat; this affects what gets refunded and what's left to use
• Outstanding HDB loan or bank loan balance; this shapes your net proceeds
• Any grant clawback conditions tied to how you originally bought the flat

Sequencing a Sale and Purchase Without Double Mortgages

Here's the part most people get wrong. They sell first, then panic-search for a new place while paying rent. Or they buy first and get stuck carrying two loans. Right-sizing and selling only works if the two transactions are timed against each other, not done one after the other blindly.

I map this out with clients before we even list. We work backwards from your target move date, not forwards from whenever a buyer shows up.

• Get a realistic valuation and check your CPF and loan numbers first
• Start shortlisting your next property while we prepare your current one for the market
• Once an offer comes in, we negotiate the completion date to line up with your purchase
• Structure the option period so both deals complete close together
• Move once. No storage, no interim rental, no second mortgage sitting on your account

When Right-Sizing Isn't the Right Move

Not everyone who calls me should sell right now. If you're on an HDB flat and haven't cleared your Minimum Occupation Period yet, you can't sell on the open market at all. Same story if your mortgage is still near the start; the numbers rarely work out in your favour that early.

There's also the emotional side. I ask a simple question early on: are you moving because you want to, or because someone told you it's time? Those are very different conversations.

• You haven't hit your property's minimum holding or occupation period yet
• Your current mortgage still has most of its tenure left, with little equity built up
• Your family's space needs are likely to grow again in the next few years
• You're selling out of pressure from others, not your own timeline
• You haven't checked what you'd walk away with after fees and outstanding loan

If any of that sounds like you, wait. A rushed sale to buy smaller almost never saves money the way people expect - it just moves the stress from one move to two.

Resale Levy, SSD, and Other Costs That Shift the Numbers

Here's what trips people up. They work out their sale price, their next home's price, and think the sum is clean. It's rarely that clean.

If you're moving from one HDB flat to another and you've taken a housing subsidy before, a resale levy may apply. Then there's seller's stamp duty, or SSD, which applies if you sell within a certain holding period after buying.

• Outstanding home loan and CPF refund owed on the flat you're selling
• Agent commission on the sale
• Buyer's stamp duty on the next home, if it applies to you
• Any resale levy or SSD flagged during the check
• Renovation or moving costs for the new place

None of these are fixed numbers I can quote you here. That's exactly why we run the full numbers before you sign anything, not after.
