Realistic Rental Yields on Thai Condos: What Numbers Actually Look Like

Developers marketing Thai property to foreign investors frequently cite rental yields of 7–10%. These numbers are gross yields in optimistic scenarios. The realistic net yield after all costs and vacancies is materially lower. Here is an honest accounting.

Gross vs Net Yield

Gross yield = (Annual rental income / Purchase price) × 100 Net yield = (Annual rental income – all costs) / Purchase price × 100

The difference matters significantly in Thailand:

Cost Item	Typical Amount
Property management fee	15–25% of gross rent
Vacancy allowance	10–20% of potential rent
Common area maintenance	฿800–3,000/month
Property tax (new 2020 law)	0.02–0.1% of assessed value/year
Maintenance and repairs	฿5,000–20,000/year
Insurance	฿3,000–8,000/year

Realistic Yield by City and Property Type

Bangkok — Mid-Market Condo (฿3–8M)

Gross yield: 4–6%
Net yield after costs: 2.5–4%
Best performers: Studio/1BR in BTS-adjacent buildings, well-managed with strong occupancy

Bangkok — Premium Condo (฿8M+)

Gross yield: 3–5%
Net yield: 1.5–3.5%
Note: Premium condos depreciate less and appreciate more, so total return can still be attractive

Phuket — Resort/Holiday Condo

Gross yield: 6–10% (marketed)
Net yield: 4–7% (reality, including high vacancy and management costs)
High-season performance can be very strong; low-season performance is weak

Pattaya — Mid-Market Condo

Gross yield: 5–8%
Net yield: 3–5.5%

Chiang Mai — Mid-Market Condo

Gross yield: 4–6%
Net yield: 2.5–4%

The "Guaranteed Rental Return" Warning

Many Thai developers offer guaranteed rental returns (e.g., "7% guaranteed for 5 years"). Key facts:

The guarantee is paid by the developer from cash reserves or future project profits—it is not third-party insured
After the guarantee period ends, the real market yield may be significantly lower
Some developers structure guarantees by inflating the purchase price to "fund" the guarantee period
They are useful as cash flow management tools but should not be the primary investment thesis

Capital Appreciation Component

For many successful Thai property investors, capital appreciation (not yield) has been the primary return driver:

Bangkok prime property: 5–8% annual appreciation since 2015 in BTS-corridor properties
Phuket premium: 8–15% annual appreciation in Bang Tao since 2020
Total return (yield + appreciation) can be 8–12% annually in the right assets

Tax Considerations

Personal income tax on rental income: 0–35% depending on total income (Thailand requires foreigners to file if they have Thai-source income)
Land and Buildings Tax: 0.02% of appraised value for non-owner-occupied condos, 0.1% for commercial

Key Takeaway

A realistic net rental yield target for a well-chosen Thai condo is 3–5% in Bangkok and Chiang Mai, 4–7% in Phuket and Pattaya resort properties. Add expected capital appreciation of 4–8% for total return projections. Do not base your investment decision on developer-advertised gross yields alone.
