Should you buy in Bangkok to rent it out? An honest yield read

Gross rental yield is the standard yardstick for a condominium in central Bangkok bought to rent out: one year of rent measured against the purchase price. Across our market ledger, 51 prime buildings and 1,501 listed units as of July 2026, most buildings that carry both sale and rental listings for comparable homes work out between roughly 3 and 5 percent gross on asking terms, before any costs. The honest part of the story is what happens after.

The ledger, read plainly

The method is simple. Take a building where the ledger holds both sale and rental listings for the same bedroom count and comparable sizes, set the median asking rent over a year against the median asking price, and read the result as an indicative gross yield.

MARQUE Sukhumvit is the deepest pairing we track. Twenty-nine two-bedroom sale listings between 126 and 195 sq m carry a median asking price of 53.0 million baht; twenty-eight rental listings in the same size band carry a median asking rent of 160,000 baht a month. A year of that rent is 1,920,000 baht, an indicative gross yield of about 3.6 percent.

Repeat the exercise across the ledger and most pairings land between roughly 3 and 5 percent gross, with tails on both sides. These are asking prices and asking rents, not achieved transactions. Sellers negotiate, tenants negotiate, and both moves shift the ratio.

From gross to net

A gross figure flatters. Between it and the money that reaches the owner sit five recurring costs.

• Common-area fees, billed on the residence’s size.
• A sinking-fund contribution, paid once at transfer.
• The agent’s month. The agent who places the tenant customarily earns one month of rent on a one-year lease.
• Vacancy. The gap between tenants costs whatever the market takes to close, and a prime two-bedroom does not always re-let in a fortnight.
• Furnishing, the quiet fifth: tenants at this level expect a fully furnished home, and the fit-out is bought and refreshed on the owner’s account.

The full stack of purchase-side fees and taxes is set out in our guide to the true cost of buying in Thailand.

One agent month and one vacant month remove a sixth of the year’s rent before the first common-area invoice arrives.

What moves the real number

Four things, in our experience.

• The building. A well-managed tower re-lets faster and holds its rent.
• The layout. Across the ledger, smaller homes rent harder against their price than very large ones; at 185 Rajadamri the one-bedroom pairing reads near 3.6 percent gross while the three-bedroom pairing reads near 2.2.
• The corridor. A residence lets at the speed of its tenant pool, and each corridor draws a different one.
• The tenants themselves, who follow much the same national mix we trace in who is buying Bangkok luxury condominiums in 2026.

Branded residences run a different arithmetic

A branded residence tends to rent well. The building is run to a hotel standard, and that shows in how it lets. The yield still reads lower, because the denominator is larger: the brand premium sits in the purchase price, and rent does not rise by the same multiple. In our ledger, the two-bedroom pairing at The Ritz-Carlton Residences Bangkok reads under 2 percent gross, from a median asking price of 109.6 million baht against a median asking rent of 165,000 baht a month.

Owners there are rarely buying for the yield, and that is the point. A branded residence is a store of quality first and an income line second. For buyers who do want the income line, the entry price decides almost everything, which is why the early-phase window matters more than any headline percentage.
