Buyer Guide

3 Bedroom vs 4 Bedroom Condo: Which One Should You Buy?

Short answer: if you can afford the 4-bedroom comfortably, it is usually the better long-term buy. Bigger units are rarer, so when you sell there is less competition, and families keep wanting more space, not less. But "comfortably" is the key word. Buy the biggest you can afford comfortably, not the biggest the bank will lend you.

A client asked me this just last week: should she get the 3+study or the 4-bedroom? The 4-bedroom cost more upfront, so was it worth it? Here is what I told her.

Buyers don't stay small for long

Every buyer I sold a one-bedroom to came back to me. They were single, no kids, and one bedroom was all they wanted. But after a few years, every one of them wanted a bigger home.

The same thing happens one size up. A couple buys a 3-bedroom, then a second child comes, or a parent moves in, or both of them start working from home. The study becomes a bedroom, the third bedroom becomes an office, and the home feels small far sooner than they planned.

So before you pick a unit, ask what you will need in five years, not just what you saw in the showflat today.

Bigger units are rarer, so there's less competition when you sell

Developers build far more 2- and 3-bedroom homes than 4-bedroom homes. That shows up when you sell.

When I checked District 20 in October 2026, there were 860 three-bedroom units for sale and only 302 four-bedrooms. More than double. If you are selling a 3-bedroom, you are one of many. If you are selling a 4-bedroom, buyers who need the space have far fewer to choose from.

And as new homes get smaller, people value space more and more.

Buyers are already voting for space

At Thomson Reserve's launch on 30 and 31 October 2026, all 350 three-bedroom homes and all 174 four-bedroom homes were sold over the VIP preview and launch day. Overall 1,143 of 1,268 homes were sold, at an average of about $2,900 psf. What was left was mostly the smaller units.

What about 3+study?

A 3+study looks like a middle path, and sometimes it is. But a study is usually small and often has no window, so it rarely works as a real bedroom for a growing child or a parent. If you already know you will need a fourth bedroom within a few years, price the true 4-bedroom before you settle.

Example: Aurea, 3-bedroom vs 4-bedroom

To make it concrete, here are Aurea's starting prices from the developer's price list, as of 4 November 2026:

Type Size From From psf 25% you pay before the loan Buyer's Stamp Duty
3 Bedroom 1,001 sqft $2,666,600 about $2,664 $666,650 $102,930
4 Bedroom 1,442 sqft $4,080,510 about $2,830 $1,020,128 $184,431

The 4-bedroom here is about 440 sqft bigger and about $1.41 million more. Your own 25% share goes up by about $353,000, and stamp duty by about $81,500. That is real money, and it's exactly why the word "comfortably" matters.

Starting prices are the lowest of each type; higher floors and better stacks cost more. See the live Aurea prices and units left.

Don't stretch for the biggest unit

Does all this mean you should stretch for the biggest unit you can get? No.

Buy the biggest you can afford comfortably. There is no point getting a bigger house if your quality of life drops because of the mortgage. Before you decide, I look at three things with my clients:

  1. Cash and CPF on day one: your 25% share plus stamp duty, without emptying your emergency savings.
  2. The monthly instalment at full loan, worked out at a higher interest rate than today's, not just the current one.
  3. Your plans for the next five years: kids, parents, job changes and when you might sell.

If the 4-bedroom passes all three, it is usually the stronger buy. If it only works by squeezing every month, the 3-bedroom is the better home for you right now.

Frequently asked questions

Is a 4-bedroom condo easier to sell than a 3-bedroom? Usually there is less competition, because far fewer 4-bedrooms are built and listed. In District 20 in October 2026 there were 302 four-bedrooms for sale against 860 three-bedrooms. The buyer pool is smaller too, so price it right.

Is a 3+study the same as a 4-bedroom? No. A study is usually smaller and may have no window. Check the floor plan and the room size before you count it as a bedroom.

How much more cash do I need for a 4-bedroom? Your 25% share and stamp duty both grow with the price. At Aurea's starting prices the gap is about $353,000 more in your share and about $81,500 more in stamp duty.

Should I buy the biggest condo I can afford? Buy the biggest you can afford comfortably. Leave room for savings and for interest rates going up.
