For many US citizens, Thailand represents the ultimate retirement or investment destination. The low cost of living, world-class healthcare, and tropical lifestyle are hard to resist. However, when it comes to buying real estate, Americans often encounter a maze of conflicting information.
A common question we receive is: "Does the US-Thai Treaty of Amity allow me to own land?"
The short answer is No. While the Treaty gives Americans special business privileges, it explicitly excludes land ownership. This guide clarifies exactly what you can own, what you can't, and the legal structures that keep your investment safe in 2025.
Why You Can Trust Us
At Thai Investment Visa, we navigate the intersection of immigration and property law daily. We work alongside the Land Department and top-tier legal counsels to ensure our clients—ranging from retirees to high-net-worth investors—don't fall into "nominee" traps. We have seen firsthand the risks of unregistered leases and the benefits of legitimate freehold ownership. The advice below is verified against the latest 2025 Civil and Commercial Code updates.
The Treaty of Amity: The Big Myth
Many Americans believe the Treaty of Amity and Economic Relations (1966) allows them to buy land because it grants 100% company ownership.
- The Reality: Article V of the Treaty specifically excludes "the exploitation of land or other natural resources."
- The Result: You can own 100% of a Thai company, but that company cannot own land if it is majority-owned by Americans. It is treated as a "foreign entity" under the Land Code.
Option 1: The Safest Bet – Freehold Condominiums
For US citizens, this is the gold standard. Under the Condominium Act, foreigners can legally hold the title deed (Chanote) in their own name, 100% freehold.
The 49/51 Foreign Quota
Every condo building has a "Foreign Quota." Up to 49% of the total floor space can be owned by foreigners. The remaining 51% must be owned by Thais.
- Pros: You get a government-issued title deed. You can sell, mortgage, or inherit the unit freely.
- Cons: You don't own the land itself, just the unit and a share of the common property.
The "FET" Requirement
To register the deed, you must show a Foreign Exchange Transaction (FET) Form. This proves you transferred USD (or another foreign currency) into Thailand specifically for this purchase. Do not bring cash in a suitcase or transfer Thai Baht from a friend's local account.
Option 2: Land & Villas – The Leasehold Reality
If you want a pool villa in Phuket or a retirement home in Chiang Mai, you are likely looking at a Leasehold structure.
The 30-Year Limit
Foreigners cannot own land, but they can lease it.
- Maximum Term: The law allows a maximum registered lease of 30 years.
- The "90-Year" Myth: You will often hear about "30+30+30" leases. Be very careful. Only the first 30-year term is guaranteed and registered on the title deed. The renewal clauses are merely contractual promises. If the landlord sells the land or passes away, enforcing a renewal can be a legal nightmare.
Option 3: The LTR Visa Exception (Wealthy Global Citizens)
There is one narrow path for wealthy Americans to own land (1 Rai, approx. 0.4 acres) for residential use.
- The Visa: You must hold a Long-Term Resident (LTR) Visa.
- The Investment: You must invest at least 40 Million THB (approx. $1.15M USD) in Thai government bonds or other specified assets for at least 3 years.
- The Catch: This permission is granted by the Minister of Interior on a case-by-case basis and is revocable if you sell the investment.
Option 4: Usufructs and Superficies
These are lesser-known rights under the Civil and Commercial Code.
- Usufruct (Sidhi-kep-kin): The right to use and manage a property. It can be granted for a lifetime. It is often used between spouses (e.g., a Thai wife grants a Usufruct to her American husband). It ensures you can live in the house even if she passes away, but it cannot be sold or inherited.
- Superficies: The right to own the building upon the land, but not the land itself. You register ownership of the house structure, while the landowner retains the title to the dirt.
Buying Process: A Step-by-Step Guide
- Due Diligence: Never skip this. Check the title deed (Chanote) to ensure the seller actually owns the land and there are no mortgages attached.
- Sales & Purchase Agreement (SPA): Have a lawyer review this. Ensure penalty clauses for late transfer are included.
- Deposit: Usually 10% to lock in the price.
- Transfer at Land Office: You pay the remaining balance via cashier's check, and the Land Officer updates the back of the title deed with your name.
Hidden Costs: Taxes & Fees
Budget for these transfer costs (usually shared between buyer and seller):
- Transfer Fee: 2% of appraised value.
- Stamp Duty: 0.5% (if exempt from Specific Business Tax).
- Specific Business Tax: 3.3% (if the seller has owned it for less than 5 years).
- Sinking Fund: A one-time fee for new condos to cover future building repairs.

Frequently Asked Questions
- Can I inherit land in Thailand as an American?
Technically, yes, as a "statutory heir." However, you cannot keep it permanently. The Land Code requires you to sell the land within a specific timeframe (usually 1 year) to a Thai national. You cannot register the title in your name indefinitely.
- Can I buy a house in my Thai wife's name?
Yes. This is very common. However, the Land Department will require you to sign a "Letter of Confirmation" stating that the money used is her personal property (Sin Suan Tua), not marital property. Legally, you are waiving your claim to the land.
- Can I get a mortgage in Thailand?
It is difficult but possible. MBK Guarantee and UOB Bank offer financing options for foreigners buying condos, often up to 50% of the value. Interest rates are higher than in the US.
- Does buying a condo grant me a visa?
No. Buying a condo gives you a place to sleep, not the right to stay. You still need a visa (Tourist, Retirement, LTR, or Privilege Visa). However, some developers offer "Elite Visa" packages bundled with luxury units.
- Is it safe to buy "off-plan" (pre-construction)?
It carries risk. If the developer runs out of money, you can lose your deposit. Always buy from public listed developers (e.g., Sansiri, Noble, Land & Houses) to minimize this risk.
