Leasehold vs Foreign Quota in Thailand: What You Actually Own

The single sentence summary

If a Thai property is offered as foreign quota, your name goes on the chanote (title deed) at the Land Office and you own the asset outright, with the same legal rights a Thai owner has. If it's offered as leasehold, you sign a lease registered at the Land Office for a maximum of 30 years, after which the asset reverts to the freehold owner — and any "renewal options" beyond those 30 years are contractual promises that may or may not be honored by a successor in title. Everything below is detail on top.

What "foreign quota" actually is

The Thai Condominium Act B.E. 2522 (1979, amended 1991, 1999, 2008) is the legal exception that lets foreigners own — because under the Act, you don't own the land underneath the building. You own a unit (a defined air-space with common-area share) registered to your name; the land sits collectively under the condominium juristic person.

The Act caps total foreign-owned area at 49% of the building's saleable floor area. A 10,000 sqm building can sell up to 4,900 sqm to foreigners on freehold; the remaining 5,100 sqm must be owned by Thai nationals (individuals or majority-Thai-owned companies). Once that 49% is full, the next foreign buyer can only buy on leasehold or wait for a foreign-quota resale.

The chanote you receive carries your full name, nationality, passport number, and unit details, with a "foreign-quota" notation. You can rent the unit out (subject to building rules), sell it (to a Thai or to another foreigner who keeps the building inside the 49% cap), mortgage it (at a small set of foreigner-friendly banks), and bequeath it to your heirs — including foreign heirs.

What leasehold actually is

A registered lease grants you the right to use and occupy a property for a defined term, noted on the freehold owner's title deed. The Civil and Commercial Code §540 caps the residential lease term at 30 years. Any clause attempting to extend beyond 30 years is unenforceable at registration — the Land Office will register only the first 30.

What about "30+30+30 — effectively 90 years" that you'll see advertised everywhere?

1. The first 30 years are legally registered and enforceable. Sign and register today, you have a right to occupy until 2056.

2. The "+30+30" renewals are contractual promises, typically structured as options-to-renew exercisable at the end of each 30-year period. Whether they're honored depends on the freehold owner at the time of renewal — who may not be the original signer. Thai courts have repeatedly held that an option to renew beyond the statutory 30-year cap does not bind a successor in title. If the original freeholder dies, sells, or goes bankrupt, your renewal option becomes a claim against them personally — useless if the asset has moved.

A stable developer with institutional reputation usually honors renewals. A single-purpose company set up to hold one villa? Your renewals are worth roughly the paper they're printed on.

Side-by-side: what you actually own

The 90-year cost comparison nobody runs

Rough comparison for a ฿8,000,000 1BR condo in Bangkok, held for 90 years with no inflation adjustment:

Foreign quota: ฿8M upfront + 3.5% transaction costs (฿280K) = ฿8.28M, asset retained throughout. After 90 years you (or your heirs) still hold an asset worth at least the original ฿8M, plus market appreciation.

Leasehold "30+30+30": Often priced 25-30% below foreign-quota equivalent — say ฿6M upfront + 1.5% (฿90K) for the first 30-year lease registration. Renewals at year 30 and 60 typically require fresh "registration costs" (realistic contracts quote 10-15% of then-market value).

Realistic case:

• Year 0: ฿6M + ฿90K = ฿6.09M
• Year 30: renewal at 12% of market value (now ฿14M) = ฿1.68M
• Year 60: renewal at 12% of market value (now ฿32M) = ฿3.84M

Total cash out over 90 years: ~฿11.6M for a use right that ends with you holding nothing.

Foreign quota: ฿8.28M for an asset you still own. Leasehold: ฿11.6M for nothing at the end. Leasehold is only "cheaper" if you stop the comparison at year 30 and assume renewals are free.

Where leasehold actually wins:

• Beachfront / sea-view villas where freehold isn't on the table and the alternative is rent
• Short-horizon plans (10-15 years in Thailand, treating leasehold as prepaid rent)
• Hard-capped budgets where leasehold unlocks a unit you couldn't afford freehold

Decision tree — which one for you?

Q1: Condo or villa/house with land?

• Condo → Foreign quota first. Always. If quota is closed, ask about leasehold of a Thai-quota unit, but know you've moved into a different legal regime.
• Villa with land → Foreign quota doesn't exist. Leasehold (registered, stable freeholder), Thai-spouse + usufruct, or rent. See Foreign Property Ownership in Thailand: The 2026 Guide for the full villa-structure menu.

Q2: Horizon?

• Lifetime / multi-generational → Foreign quota. Leasehold's decay penalty over 50+ years is brutal.
• 15-25 years → Leasehold can be defensible if priced 20-30% below comparable foreign-quota and the freeholder is institutional.
• Under 10 years → Rent.

Q3: Budget flexible or hard-capped?

• Flexible → Foreign quota.
• Hard-capped → Leasehold opens locations and sizes you couldn't otherwise reach. Price the renewal cost into your model.

Q4: Exit liquidity?

• Critical → Foreign quota — much deeper buyer pool.
• Doesn't matter (final home) → Either, depending on Q1-Q3.

What MangoGo shows you

Every condo listing carries one of three ownership badges: Foreign quota — open (preferred), Foreign quota — closed (available only on leasehold of a Thai-quota unit), or Leasehold registered (XX years remaining) (the actual remaining term, not the marketing "90 years"). Villa listings show the registered freeholder, the lease structure, and a "structure check recommended" flag for anything sold via Thai limited company — the data point every other Thai portal hides until inquiry stage.
