Two words decide what you really buy in Thailand. Freehold is outright, perpetual title in your name — and for a foreigner that's realistically only a condo, inside the building's 49% quota. Leasehold is a fixed right to use, capped at 30 years per registered lease, with someone else still holding the title. The gap between a confidently marketed "30+30+30" and what the law will actually enforce is where foreigners lose money. This guide walks the real rules: the 30-year ceiling, the renewal reality, registration, and when each route makes sense. Unbiased, never paid placement.
Freehold if you can, leasehold if you must. A foreigner's one clean freehold is a condo inside the 49% quota; everything else — land, houses, quota-full buildings — usually means leasehold. Trust the first 30 years of any lease and treat advertised "+30+30" renewals as hopeful promises, not registered rights. Register any lease over three years, and never pay a freehold price for a leasehold asset.

Freehold (in Thai practice, ownership of the title) means the property is yours in perpetuity, your name is on the deed, and you can sell, will or mortgage it as an owner. Leasehold means you hold a registered right to use the property for a fixed period — up to 30 years per lease — while the title itself stays with the owner. The difference isn't academic: it changes what you can pass to your heirs, how easily you can resell, how much the asset is worth, and what you're left with when the term ends. Before you fall for a unit, settle which one you're actually being offered. The wider rules sit in our guide to foreign condo ownership & the 49% quota.
Thai law caps a registered residential lease at 30 years. You'll constantly see developments marketed as "30+30+30" — a 30-year lease with two renewal options, implying 90 years of security. The catch: only the first 30 years is a registered, enforceable right. The renewals are contractual promises that rely on the lessor still existing and still willing to renew three decades from now, and Thai courts have not reliably forced pre-agreed renewals onto a later owner of the land. Plan your life and your money around 30 solid years; regard anything past that as a best-effort bonus, not a guarantee. This is the single most expensive misunderstanding foreigners make.
The condominium is the exception that lets a foreigner own genuine freehold. You can hold a unit outright, in your own name, as long as the building is within its 49% foreign-ownership quota and your money came from abroad via the FET. That's why so much foreign buying concentrates on condos: it's the cleanest title a foreigner can get, with full owner's voting rights and the most liquid resale. When a building's foreign quota is full, though, the only way in may be a leasehold unit — same apartment, weaker right, and it should be priced lower to match. Read why the FET form is non-negotiable, and see the deed itself in Thai title deeds (Chanote).
Foreigners generally cannot own land freehold in Thailand. So a house or villa typically means one of these, each with trade-offs:
Nominee arrangements — Thai names "holding" land for a foreigner — are illegal and can void your interest entirely. Always use an independent lawyer; see hiring a lawyer in Thailand before signing anything on land.
A lease over three years must be registered at the Land Office to be enforceable for its full term; left unregistered, even a 30-year lease is only valid for three. Registration records your right against the title, so it survives if the property is sold to someone new — the protection a private contract in a drawer can't give you. Expect a registration fee and stamp duty of roughly 1.1% of the total rent across the whole term, plus your lawyer's fee to draft and vet the lease. Skipping registration to save that cost is a classic false economy that can cost you the entire asset. Model the buy-side numbers with our purchase-cost calculator.
A leasehold is a wasting asset: every year, one year less remains, and its resale value falls accordingly. A freehold doesn't decay that way. So a leasehold unit should always cost less than the equivalent freehold — if a developer prices them the same, you're overpaying for the weaker right. And be honest about the endgame: unless a renewal is granted, at term's end the right reverts to the owner and you're left with nothing, with any building on leased land potentially reverting too.
