The Real Cost of Owning a Home in Thailand

Beyond the sale price: what buying, owning, and eventually selling actually costs in 2026.

The listing price is never the whole story. Between transfer fees, taxes, common area charges, and insurance, the real cost of owning property in Thailand plays out in three separate stages: when you buy, every year you hold it, and again when you eventually sell. Here’s what each stage actually costs, using 2026’s current rates.

1️⃣ At Purchase: Land Office Costs

Every registered property transfer in Thailand involves the same core charges, calculated on whichever is higher — the government’s official appraised value or the declared sale price:
    • Transfer Fee — 2% of the appraised value, customarily split 50/50 between buyer and seller (negotiable, not required by law)
    • Specific Business Tax (SBT) — 3.3%, charged instead of stamp duty if the seller has owned the property for under 5 years or the sale counts as commercial
    • Stamp Duty — 0.5%, charged only when SBT doesn’t apply — the two are never both charged on the same sale
    • Withholding Tax — a flat 1% of value if the seller is a company; a more complex progressive calculation if the seller is an individual
Add it up, and total government charges at the Land Office typically land somewhere between 2.5% and 6.3% of the appraised value, depending on who’s paying what and the seller’s holding period. Budgeting 6–8% of the purchase price for total one-off transaction costs (including legal fees and due diligence) is a realistic planning figure. One thing worth flagging: Thailand has run a temporary reduced transfer fee (as low as 0.01%) for residential property under a set price threshold as part of a domestic stimulus scheme — but this discount is reserved for Thai nationals. Foreign buyers remain on the standard 2% rate regardless of property value.

2️⃣ Every Year You Own It: Land and Building Tax

Since the Land and Building Tax Act B.E. 2562 replaced the old House and Land Tax, annual property tax has applied every year — and 2026 is the first year running at full statutory rates, without the pandemic-era discounts (up to 90% off) that softened the bill for several years running.

🏠 Registered as Your Primary Residence

Rates run 0–0.10% of appraised value, progressively. Individually-owned land-and-house residences also benefit from an exemption on the first 50 million THB of combined value.

🏢 Second Home, Investment, or Rental

Rates run 0.02–0.30% of appraised value, progressively — higher than owner-occupied, without the same generous exemption thresholds.

In practical terms, these numbers are modest. A 5 million THB condo held as an investment property at the 0.02% rate comes to roughly 1,000 THB a year — often less than a single month’s common area fee. Foreign-owned condos are subject to exactly the same rates as Thai-owned property; there’s no separate foreigner surcharge on the annual tax itself.

🏗️ The Costs That Actually Add Up: CAM, Sinking Fund & Insurance

For condo owners specifically, the annual property tax is rarely the real financial story — the recurring building costs are:
    • Common Area Maintenance (CAM) / juristic fees: charged monthly per square metre, covering shared facilities, security, and building upkeep — this is typically the single largest recurring cost of condo ownership, well above the annual property tax.
    • Sinking fund: a one-time contribution collected at purchase for the building’s long-term major repairs and capital reserve.
    • Home/contents insurance: typically 4,000–8,000 THB per year for standard coverage on a mid-range unit, rising to 10,000–15,000 THB for higher-value contents. If you plan to rent the unit out, budget 20–30% higher — landlord policies cost more than owner-occupier ones.
A realistic all-in recurring cost for condo ownership — CAM, sinking fund contributions, insurance, and annual property tax combined — typically runs 0.5% to 2.0% of the property’s value per year.

3️⃣ If You Ever Rent It Out

Rental income earned from Thai property is taxable in Thailand regardless of the owner’s nationality or residency status. Non-resident owners are generally subject to 15% withholding tax on rental income, compared with 5% for Thai tax residents — worth factoring into your yield calculations before committing to a rental strategy.

4️⃣ Eventually, If You Sell

The same core costs from purchase apply in reverse — transfer fee, SBT or stamp duty, and withholding tax, this time typically weighing more heavily on the seller by custom. The one relief worth knowing: properties acquired by inheritance qualify for an SBT exemption regardless of how long they’ve been held, recognizing that inheriting a property isn’t a commercial transaction.

A Worked Example

Take a 5,000,000 THB condo, purchased as an investment property and held long-term:

    1. At purchase: roughly 300,000–400,000 THB in combined transaction costs (6–8%)
    1. Each year after: roughly 1,000 THB in Land and Building Tax, plus CAM (often the largest line item), a sinking fund contribution at purchase, and 4,000–8,000 THB in insurance — combining to roughly 25,000–100,000 THB per year depending on the building’s CAM rate

None of these numbers are alarming on their own — but they add up to a meaningfully different total cost of ownership than the sale price alone suggests, and they’re exactly the kind of detail worth mapping out before you make an offer, not after you’ve already signed.

Frequently Asked Questions

Do foreigners pay higher property taxes than Thai nationals?

Not on the annual Land and Building Tax — foreign-owned condos are taxed at the same rates as Thai-owned ones. The one place foreigners lose out is the transfer fee: reduced-rate stimulus schemes for buyers under a certain price threshold are reserved for Thai nationals.

Is CAM negotiable, or set by the building?

It’s set by the building’s juristic person (management committee) and applies uniformly per square metre to every owner — not something an individual buyer can negotiate. It’s worth comparing CAM rates across buildings before buying, since it’s a recurring cost for as long as you own the unit.

Who actually decides whether I pay SBT or stamp duty when I sell?

It’s determined automatically by how long you’ve owned the property — under 5 years generally triggers SBT (3.3%), over 5 years generally shifts you to stamp duty (0.5%) instead. The two are never charged together.

🔑 Key Takeaways

    • Budget 6–8% of purchase price for one-off transaction costs at the Land Office
    • Annual Land and Building Tax is modest (often under 0.1%) but CAM and insurance are the real recurring costs
    • Foreigners pay the same annual property tax rates as Thai owners — the gap shows up in transfer fee stimulus schemes, not ongoing tax
    • Rental income is taxable regardless of nationality, with a higher 15% withholding rate for non-residents
    • A realistic all-in annual cost of ownership runs 0.5–2.0% of property value
