The real risks for foreign real-estate investors in Thailand

On paper, the rules for foreign property buyers in Thailand have not changed. As of June 2026, foreigners still cannot own land in their own name (narrow exceptions such as BOI-promoted investment rarely help individual buyers), foreign freehold in a condominium building is still capped at 49% of the saleable area, and the longest lease you can register is still 30 years.

What has changed — dramatically — is enforcement. Since late 2025, six government agencies share data on company ownership and land holdings, an AI system screens for disguised foreign ownership, and the Supreme Court has struck down the lease-renewal promises that agents sold for two decades. Structures that were marketed as "standard" in 2019 are genuinely dangerous in 2026.

Here is the honest risk map as of June 2026 — and, at the end, the checklist that prevents most of these problems.

Title risk: not every land document is a real title

Thai land documents come in a hierarchy, and only the top is safe. A Chanote (Nor Sor 4 Jor) is the only fully surveyed freehold title, with GPS-fixed boundary markers. A Nor Sor 3 Gor is a confirmed possessory title based on aerial survey — transactable, but boundaries can shift on a precise re-survey.

Below that, a plain Nor Sor 3 has never been precisely surveyed, and lesser possessory papers are not titles in any meaningful sense. The practical rule: transact only on Chanote or Nor Sor 3 Gor.

One more surprise: even Chanote land can be lost. Under Section 1382 of the Civil and Commercial Code, ten years of open, continuous possession by a squatter or encroaching neighbour can ripen into ownership by court order — this is adverse possession. Inspect, fence and check your land regularly.

Off-plan risk: you are financing the developer, not the other way round

Escrow — a neutral account that holds your money until the property is delivered — is voluntary in Thailand under the Escrow Act of 2008, and most developers do not offer it. Paying instalments on an off-plan condo is effectively an unsecured loan to the developer: if it fails mid-construction, you may recover little or nothing.

One genuine improvement arrived on 31 January 2025: an OCPB (consumer-protection board) notification made condo reservation sales a contract-controlled business. Liability-exclusion and unilateral-amendment clauses are banned, and refunds, where due, must be paid within 15 days (bank transfer) or 45 days (credit card). That protects your reservation deposit — not your construction instalments.

The defence is unglamorous: a litigation and financial check on the developer before signing, a payment schedule weighted towards completion, and contract terms reviewed by your own lawyer — see our due diligence service for what that involves.

Leasehold risk: 30 years means 30 years — the "30+30+30" era is over

For years, villas on leased land were marketed as "90 years of ownership": a registered 30-year lease plus two pre-agreed 30-year renewals. Supreme Court Judgment No. 4655/2566, reported in March 2025, ended that: renewal options agreed in advance, beyond the initial 30 years, are void as contrary to public policy. Your lease is enforceable for its registered 30 years — the renewal promises are worth nothing, even if you paid extra for them.

Nor is rescue coming from parliament: the much-publicised 99-year leasehold bill was shelved by the incoming government in September 2025, and as of June 2026 the maximum registrable lease remains 30 years. A renewal can still happen — but only if the landowner freely agrees again at year 30.

Value and price any leasehold purchase as a 30-year right — we unpack what the "30+30+30" structure really gives you in our guide to the 90-year lease. A brochure still promising "90 years" is a red flag about everything else in it.

Nominee company risk: from grey area to active crackdown

The classic workaround — a Thai company with Thai shareholders holding 51% on paper while a foreigner controls everything and the company owns the villa — has always been illegal. What changed is detection. Since October 2025, the Department of Business Development (DBD) runs an AI screening system that cross-references the corporate registry, the land registry and other government databases to flag nominee patterns — for example, a tiny-capital company holding expensive land. The DBD, Land Department, DSI, Immigration, Revenue Department and AMLO now share data.

The scale is not theoretical: roughly 46,000 entities have been flagged for inspection across six high-risk sectors including real estate, tourism and hotels, hundreds of companies have been prosecuted, and raids continue — one Phuket operation in May 2026 saw more than 200 officers search 14 locations and seize 37 land title deeds.

The rules keep tightening. Since 1 January 2026, Thai shareholders in new companies with foreign shareholders or foreign authorised directors must show bank statements proving they funded their own shares, and a follow-up registrar's order extends the same scrutiny to share transfers, capital increases and director changes from April 2026 — confirm the current position with us before touching any structure.

The penalties in force today: under the Foreign Business Act, up to 3 years in prison and/or a THB 100,000–1,000,000 fine; under the Land Code, up to 2 years in prison and a forced sale of the land within 180 days to 1 year. Confiscation without compensation is a proposed amendment, not current law — but a forced sale of your home on a deadline is damaging enough. If you already hold property this way, read our guide to nominee structures and how to exit them.

Condo quota and FET errors: the paperwork that can sink a clean deal

The condominium foreign quota is still 49% per building. You may have read that it is rising to 75% — as of June 2026 that is a government proposal under study, with no draft law enacted. Verify the live quota at the Land Office before paying any deposit; we explain how the quota works in our guide to the 49% rule.

The second trap is the FET. To register foreign freehold in a condo, you must prove that 100% of the price was remitted into Thailand in foreign currency, in your own name, with the purpose stated as a condominium purchase. Banks automatically issue a Foreign Exchange Transaction (FET) form for inflows of USD 50,000 or more; smaller transfers still need a bank credit advice as evidence.

The common fatal errors: sending baht instead of foreign currency, sending from a spouse's or company's account, or a vague stated purpose. Any of these can block registration — or, years later, repatriation of your sale proceeds. And from 29 December 2025, Bank of Thailand Circular No. 8434/2568 requires banks to verify supporting documents for foreign-currency inflows of USD 200,000 or more, so prepare large-transfer paperwork in advance.

Zoning and building permits: the villa problem

With villas, the risk often sits in the land and the building rather than the contract. Before buying, your lawyer should verify the zoning and any environmental overlays on the plot, and confirm that the building permit matches the structure actually standing on it — additions built without a permit are a liability you inherit.

Phuket is the cautionary tale. Its hillside rules were overhauled effective 14 December 2024: building at 80–140 metres elevation is now allowed, but only a single structure up to 6 metres high and 90 square metres of footprint, on land owned or lawfully possessed before the December 2017 environmental rules, with at least 70% of the plot kept green. Slopes of 35 degrees or more remain unbuildable, and villa or resort clusters above 80 metres remain prohibited. Many existing hillside villas breached the earlier rules and face stop-work or demolition orders under the Building Control Act — a sea view does not legalise the building beneath it.

Rental yields and the hotel-license trap

Rental returns are real but ordinary: gross yields averaged about 6.3% nationally in 2025; Phuket runs roughly 4.5–9% gross depending on product, with 5–6.5% net considered excellent. Be sceptical of "guaranteed 7–10%" offers — a guarantee is only as good as the developer's solvency, and several resort markets are oversupplied in 2026: secondary condos in Patong and Kata take 8–14 months to sell, and Bangkok new completions fell about 23% in 2025.

The bigger trap is legal. Renting out a condo or villa for under 30 days without a hotel license breaches the Hotel Act: fines up to THB 20,000 plus THB 10,000 per day the offence continues, and up to one year of imprisonment. Enforcement intensified through 2025–26, with authorities cross-checking Airbnb and Booking.com listings against hotel registrations in Phuket, Pattaya and Chiang Mai.

There is a legal route for small operators: a ministerial regulation in force since 30 October 2023 exempts registered "non-hotel" accommodation of up to 8 rooms and 30 guests from the hotel-license requirement — register with the local registrar, renew every 5 years. Rentals of 30 days or longer fall outside the Hotel Act.

Getting your money out: exit taxes and repatriation

Selling costs more than buyers expect — budget roughly 5–7% of the price in total: a 2% transfer fee on the official appraised value (customarily split between the parties), either 3.3% specific business tax if you sell within 5 years of registered ownership or 0.5% stamp duty after that, plus withholding tax — 1% for company sellers, and a progressive scale on the appraised value for individuals. The government's reduced-transfer-fee stimulus schemes have generally applied to Thai buyers only.

Once taxes are settled, repatriating the proceeds is freely allowed — but your Thai bank will demand the original FET evidence from when you bought, the sale agreement and the Land Office tax receipts. Losing the FET can block or badly delay getting your money out. Keep it as carefully as the title deed itself.

The due-diligence checklist that prevents 90% of problems

Almost every disaster we are asked to clean up would have been caught by a routine that costs a small fraction of the purchase price. Before any money moves:

• Land Office title search — confirm the registered owner, the deed type (Chanote or Nor Sor 3 Gor only), and every encumbrance on the reverse of the deed: mortgages, usufructs, servitudes, prior leases.
• Access — confirm registered road access or a registered right of way. Landlocked plots are worth a fraction of their asking price.
• Zoning and environment — check zoning, elevation and environmental overlays before any villa or land purchase, especially on hillsides and near the sea.
• Building permit — verify the permit exists and matches the actual structure, including extensions and the pool.
• Developer checks — for off-plan, run litigation and financial checks on the developer and insist on the OCPB-compliant contract terms in force since January 2025.
• Condo quota — verify the building's live foreign quota at the Land Office before paying a deposit.
• Money trail — remit in foreign currency, in your own name, with the correct stated purpose; obtain and keep the FET form or credit advice.
• Structure — register your lease, value it as 30 years, and never accept a nominee shareholding arrangement, whatever the agent says.
