Own property in Thailand without owning the risk.

We verify the land, structure the ownership, model the returns and supervise the build — through a network we have worked with on the ground.

Thailand rewards the informed buyer and punishes the trusting one.

01
The risk

Three problems, solved before they cost you money.

A title you cannot build on

Not every document gives the same rights. Setbacks, slope limits and access issues only appear at the Land Office.

A structure that will not hold

Nominee companies, leases with no renewal mechanism, entities with no substance. We build the version that survives scrutiny.

A build nobody is watching

An owner abroad and a contractor with no accountability is the fastest way to lose a budget. We put eyes on the site.

The filter

Out of 100 properties we are shown.

Most never reach a client. That is the part of the job nobody invoices you for, and the reason the ones you do see are worth seeing.

The method

Three moments where a project is won or lost.

Before the deposit

We read the file, not the listing.

Our contacts pull the title at the Land Office and compare what is registered with what is being sold. Half the time, that conversation ends there.

Architectural plans and legal documents
Ownership

The structure is the asset.

Lease, company, condominium quota or building ownership: the right route depends on your purpose and your exit, and it is set by a lawyer — never by a seller.

On site

Someone on the ground, every stage.

Tender, written specification, and payments released only against inspected work. An owner eight thousand kilometres away needs eyes, not photographs.

Returns

Why people look at Samui in the first place.

Indicative gross rental yields. Yours depends on location, standard and management — which is exactly what we model before you buy.

Six stages, from first call to keys.

Each one ends with a decision you make with documents in hand.

Verification

Title, zoning, access, restrictions and seller authority, before any deposit.

Structure

Lawyers set the ownership framework; we model the numbers alongside it.

Build

Tender, specification and supervision with contractors whose record we can verify.

Operate

Rental positioning, management and reporting for owners who live elsewhere.

“We were three days from signing. ARRTEA pulled the title, found the access strip belonged to a third party, and saved us the whole project.”

Questions

What investors ask us first.

Can a foreigner own property in Thailand?
A foreigner can own a condominium unit outright within the foreign quota of a building. Land cannot be held directly by a foreign individual, so villas and plots are structured differently — long lease, a Thai company with genuine substance, or ownership of the building separately from the land. The right structure depends on your purpose and horizon, and is set by a lawyer, not by a seller.
How long does a purchase take?
A condominium can complete in three to six weeks. Land and villa purchases usually run six to twelve weeks, driven by due diligence and the structure being put in place. A build adds ten to eighteen months depending on size and season.
What returns can I expect in Koh Samui?
Well-positioned villas typically achieve gross rental yields in the range of six to nine percent, with occupancy driven by season, location and management quality. We model your specific project rather than quoting an island average.
Do you charge the buyer or the seller?
We tell you exactly how we are paid on each transaction before you engage us — advisory fee, partner commission, or a combination. No arrangement is hidden inside a price.
Can you help if I have already found a property?
Yes. Verification and structuring are frequently our entry point. Send us the listing and the title reference and we will tell you what we can check and how quickly.

One call, no obligation. We will tell you whether your project is realistic in Thailand, what it should cost and what to check first.
