Buying property in Thailand as a foreigner is straightforward once you know the rules, but small oversights can be expensive and hard to reverse. These are the seven mistakes we see most often, with a short explanation of each and what to do instead. Every section links to a deeper guide if you want the detail.
Skipping Independent Legal Due Diligence and Title Deed Checks
The mistake: relying on the seller's or developer's lawyer, a brochure or verbal assurances instead of checking for yourself.
What to do instead:
- Hire an independent Thai lawyer who acts for you, not for the seller or developer.
- Confirm the type of title document. A Chanote is the full land title, a condominium unit has its own condominium title deed, and weaker land documents give weaker rights.
- Search for mortgages, liens and other claims on the property.
- Check that the seller is the registered owner and has the authority to sell.
- For new builds, check the developer's approvals and the building permit.
- Have the contract reviewed before you pay any deposit.

Incorrect Fund Transfer Procedures (Missing the FET Requirement)
The mistake: moving money to Thailand in a way you cannot document.
When a foreigner buys a condominium unit in their own name, the purchase money is normally expected to come from abroad in foreign currency, and the Thai bank that receives it issues a Foreign Exchange Transaction (FET) form. The Land Department asks for this form at transfer. Sending cash, paying from a third party's account or converting the money elsewhere first can leave you unable to register the unit in your name, and can complicate taking the money back out when you sell.
What to do instead:
- Before you send anything, ask your bank and lawyer how the transfer should be described.
- Send foreign currency, in your own name, to your own account in Thailand.
- Keep the FET form safely. You will need it at transfer and when you sell.
Our guide to transferring money to Thailand and the FET form explains the steps.
Overlooking Sinking Funds and Hidden Ongoing Maintenance Fees
The mistake: budgeting for the purchase price but not for the cost of owning the property.
- Condominiums have monthly common-area fees and usually a one-off sinking fund contribution, often paid at transfer.
- Villas in villages have village fees, and a pool and garden add their own running costs.
- Utilities, insurance and annual property taxes where they apply add to the total.
- Poorly funded buildings can raise special charges for major repairs.
What to do instead: ask the building or village management for the current fees in writing, check that the seller has no arrears, and ask how healthy the building's finances and sinking fund are. Our guide to the real cost of owning property in Pattaya lists the ongoing costs.
Falling for Unrealistic Guaranteed Rental Return Promises
The mistake: buying because of a headline return that is "guaranteed" for a number of years.
These offers can be genuine, but they rarely work the way the brochure suggests. Common structures include:
- The guarantee is built into the price, so you are paying for it up front.
- It lasts for a fixed period, after which you are on your own.
- It is funded from your own money, for example from part of your payments held back by the developer.
- It ties you to the developer's rental programme, with limits on your own use or on selling.
- It relies on short-term letting, which may need a hotel licence and may be banned by the building.
- It depends on the developer staying solvent and willing to pay.
Questions to ask before you rely on one:
- Is the guarantee written in the contract, or only in the marketing material?
- Who is giving it, and is it backed by a bank guarantee or escrow?
- What happens if payments stop?
- How does the price compare with similar units that have no guarantee?
- What rent can a similar unit in the same building actually achieve today?
Treat a brochure yield as marketing, not a forecast. Our guide to rental yields in Pattaya shows how to assess returns realistically.
Misunderstanding Land Lease Renewal Enforceability
The mistake: assuming that a lease with renewal clauses gives you the land for the full length of the clauses.
Thai law generally limits a lease of land or buildings to 30 years. Contracts often add promises to renew for further periods, for example "30+30+30 years". Those renewal promises are contractual, and whether they can be enforced beyond the registered term is debated. A safe approach is to treat only the registered term as certain.
What to do instead:
- Make sure the lease is registered at the Land Department. A lease of more than three years generally needs to be registered to be enforceable beyond three years.
- Ask your lawyer exactly what happens at the end of the term, if the landowner sells or mortgages the land, and on your death.
- Check that you can sell or sub-let the lease.
- Remember that a leasehold loses value as the remaining term shortens, and price it accordingly.

Not Checking Surrounding Zoning and Future Construction Plans
The mistake: buying for a view, a quiet street or an area's character without checking what can be built next door.
The empty plot beside a villa or the open view from a condo can disappear if the neighbouring land is zoned for development. Thailand uses colour-coded land-use plans that set what can be built where, and building height, density and setbacks are regulated.
What to do instead:
- Ask the local planning office for the zoning of the plot and the land around it.
- Look for approved or pending building permits nearby.
- Ask a developer for the master plan and phasing, and whether the view you are paying for is protected or only exists because the land is currently empty.
- Check the access road: is it public, or a private road with a right of way?
- Ask about flood history and visit in heavy rain.
- Visit at different times of day, including weekdays, to judge noise and traffic.
How Working with an Experienced Local Broker Protects Your Investment
The seventh mistake is going through the whole process without experienced local help. A good broker does not replace a lawyer, but does protect you in practical ways:
- Shortlists properties that fit your budget and goals, and filters out poor options.
- Shows realistic prices using comparable sales and explains the full cost of buying.
- Coordinates your lawyer, your bank transfer and the developer or seller.
- Negotiates, and flags red flags such as unusual payment terms.
- Supports you after the purchase, including handover checks, utilities and letting.
How to choose one: look for a local track record, ask how the broker is paid (commission is commonly paid by the seller or developer, so ask whether that affects the advice), expect them to explain the downsides as well as the positives, and ask for references. Always keep your own independent lawyer. Our guide to choosing a real estate agency in Pattaya covers this in more detail.
Checklist Before You Pay a Deposit
- An independent Thai lawyer has reviewed the contract and the title.
- You know exactly how the money will be sent, and who will issue the FET form.
- You have the current fees and sinking fund in writing.
- Any rental guarantee is in the contract and backed up.
- You know the lease term and what is registered.
- You have checked zoning, nearby permits and access.
- You know how your broker is paid.
Frequently Asked Questions
Can a foreigner own property in Thailand?
Yes, within limits. Foreigners can own condominium units freehold within the 49% foreign quota of a building, but generally cannot own land in their own name. Houses and villas are usually bought with a land lease or another structure. Take legal advice before you commit.
What is the FET form?
The Foreign Exchange Transaction (FET) form is issued by the Thai bank that receives your foreign-currency transfer. It documents that the money came from abroad, and the Land Department asks for it when you register a condo in your name.
Do I need my own lawyer if the developer provides one?
Yes. A developer's or seller's lawyer acts for them. An independent lawyer acts for you and checks the title, the contract and the structure.
Are guaranteed rental returns safe?
Not automatically. Check whether the guarantee is in the contract, who stands behind it, how long it lasts and what it costs you in the price. A guarantee is only as reliable as the party giving it.
How do I check zoning before buying?
Ask the local planning office for the zoning of the plot and neighbouring land, look for approved building permits nearby, and ask the developer for the master plan.
