Why the Cheapest Bangkok Condo Is Often the Worst Investment
The cheapest condo is usually cheap for a reason: it rents poorly. A unit with a low price per square metre but weak rental demand can return 6% while a correctly priced unit on the same street returns 10%. Price alone cannot tell them apart, only real rent can.
Cheap per square metre does not mean high yield
Price per square metre measures cost, not income. A bargain unit in a building nobody wants to rent earns little, so its yield is low despite the low price. That is a trap.
A real example
In the Ratchathewi to On Nut corridor, the lowest price-per-sqm unit returned about 6.2% gross, while a correctly priced unit nearby returned around 10%, roughly 60% more rent for similar money.
How to spot a trap
- Low price per square metre but below-median rent for the building.
- Few or no comparable rentals in the same building.
- A headline-cheap bait listing from a lead-generation reseller.
- A brand-new unit priced high by the developer, which often means low yield.
Buy on return, not on price
Rank units by the rent they actually earn relative to price, not by sticker price. CondoReturn joins each for-sale condo to live rents in the same building, flags gems and traps, and shows a confidence score for every estimate.
Frequently asked questions
- Why is a cheap condo a bad investment?
- Because price does not equal income. A cheap unit that rents poorly earns a low return, while a slightly pricier unit with strong rental demand can earn far more.
- What is a trap listing?
- A unit that looks like a bargain on price per square metre but has below-median rent for its building, so the real return is poor.
- How do I find high-yield Bangkok condos?
- Compare the asking price to the real rents of similar units in the same building and rank by return. Tools like CondoReturn automate this for every listing.
