Thailand 99-Year Leasehold Reform: What It Means for Property Investors in 2026

Thirty years. That has been the maximum land lease term available to foreign investors in Thailand for decades. It was a ceiling that kept large capital on the sidelines and pushed buyers toward complex legal workarounds. Now, that ceiling is being raised dramatically.

Thailand is preparing a reform to its leasehold property law that would extend the maximum lease term from 30 to 99 years. According to Thailand Business News, the reform is designed to stimulate the economy and attract foreign investment. For international buyers eyeing property in Phuket, Pattaya, and Bangkok, this is a key shift.

Why 99 years? Because that is the standard already in place in Singapore, Hong Kong, and the United Kingdom. Thailand is essentially aligning its legislation with the international benchmark.

Quick Answer

• Current lease limit for foreigners: 30 years with optional renewal (not legally guaranteed)
• Proposed new limit: 99 years - effectively a lifetime interest with inheritance rights
• Freehold land ownership for foreigners remains prohibited under Thai law
• Condominium units can be purchased freehold by foreigners, but only up to 49% of total floor area in any single project
• The reform primarily affects villas, townhouses, and commercial property held on leased land
• Market analysts estimate leasehold asset values could increase by 15 to 25% once the law is passed

Scenarios and Options

Scenario 1: Buying a Condominium Freehold

A foreign buyer purchases a condominium apartment in full ownership (freehold). This format does not involve a land lease, as the land is held by the condominium juristic entity. The leasehold reform does not directly affect this route. There is, however, an indirect effect: if villas become more legally attractive, some demand may shift away from the apartment segment.

Scenario 2: Buying a Villa on a 99-Year Leasehold

This is the most compelling scenario once the reform passes. Today, a Phuket villa priced between 15 and 25 million THB is typically structured as a 30-year leasehold, often with two optional 30-year renewal clauses attached. The problem is that those renewal clauses carry no legal guarantee. A 99-year leasehold eliminates that risk entirely: the investor holds the property for a term that exceeds a human lifespan.

Scenario 3: Commercial Property and Land Plots

For investors targeting hotels, retail, or office assets, a 99-year leasehold opens the door to genuine long-term planning. Lenders are more willing to finance projects with an extended lease horizon, meaning large-scale investments previously blocked by the 30-year barrier can finally move forward.

Scenario 4: Investing Through a Thai Company

Some investors incorporate a Thai company to hold land in freehold. The leasehold reform makes this structure less necessary, which in turn reduces legal complexity and ongoing costs. The Thai company structure still offers advantages for investors managing large, diversified portfolios, but it becomes harder to justify as the default starting point.

Comparison Table

Main Risks and Mistakes

1. The law has not been passed yet. As of 2026, the reform is still under discussion. Purchasing property on the assumption of a 99-year leasehold is premature. Wait for official publication in the Royal Gazette before making decisions based on the new framework.

2. Transitional provisions remain unclear. The critical open question is whether existing 30-year leasehold holders will be able to automatically extend to 99 years, or whether the reform will only apply to new contracts signed after the law takes effect. No details have been published yet.

3. Pre-reform price inflation. Developers are already using the reform news as a marketing tool. Be cautious of pitches along the lines of 'buy now before prices rise' - without enacted legislation, such arguments have no legal basis and no guaranteed outcome.

4. Tax implications may change. A longer leasehold could affect the calculation of stamp duty and transfer fees. Under the current 30-year leasehold, stamp duty is 0.1% of the total lease value. The formula for a 99-year term may be recalculated, and official guidance has not yet been issued.

5. Leasehold is not ownership. Even a 99-year leasehold is not freehold title. The lessee cannot mortgage the land, subdivide the plot, or use it as collateral without the landowner's consent. This is a fundamental legal distinction that all investors must understand clearly.

6. Fraudulent 'guaranteed renewal' contracts. The Thai market has long featured contracts claiming triple 30-year renewals totalling 90 years. Thai courts have repeatedly ruled such clauses legally unenforceable. Only a direct legislative change will resolve this issue definitively.

FAQ

When will the 99-year leasehold law come into effect? No date has been confirmed. The bill is still in the consultation phase. Analysts estimate the process will take between 6 and 18 months. Monitor publications in the Royal Gazette for official updates.

Can foreigners buy land in Thailand after the reform? No. The reform applies only to leasehold rights. Direct land ownership by foreigners remains prohibited under the Thai Land Code Act (B.E. 2497).

Does the reform apply to condominiums? Indirectly. Condominium units can already be purchased freehold (within the 49% quota). For leasehold units within condominium projects, the new maximum term would also apply.

Which provinces does the reform cover? The reform would apply nationwide. The highest impact is expected in Phuket, Koh Samui, Pattaya, and Bangkok, where foreign investment is most concentrated.

Will rental yields on villas change after the reform? Rental yield depends on short-term rental demand, not on the ownership structure. If property values rise after the reform passes, though, the percentage yield will naturally compress unless rental rates increase proportionally.

Can a leasehold be inherited? Yes. A Thai leasehold is an inheritable right within the remaining lease term. At 99 years, that becomes a genuinely attractive proposition for estate planning.

How does the reform affect resale value? Significantly. Today, a leasehold property with 15 years remaining on its term is worth considerably less than when it was purchased. Under a 99-year structure, the same property after 15 years still has 84 years remaining - preserving liquidity and market value throughout the holding period.

Should investors wait for the law or buy now? It depends on the investment objective. If a property generates solid returns and is priced fairly under current conditions, waiting may mean missing out on income. If the goal is long-term holding security, waiting for legal certainty is the more prudent approach.

What documents should buyers verify in a leasehold purchase? Start with the Chanote (Nor Sor 4 Jor), the full title deed for the land. Confirm the lessor is the registered landowner, and verify that the land is free from encumbrances, ongoing legal disputes, and unpaid taxes. Engage a qualified Thai property lawyer before signing anything.

The proposed shift to a 99-year leasehold is a serious signal: Thailand is positioning itself to compete for foreign capital alongside Singapore and Dubai. For international investors and expats looking at villas and commercial assets, it makes a strong case for the Thai market. But the operative word is compelling, not conclusive. Until the law is enacted, all decisions should be grounded in the current legal framework, not in expectations of what may come.
