A boutique property firm on Koh Samui.

We keep a deliberately small portfolio — a handful of villas we know personally, with full-service property management by a team that lives on the island.

ABOUT

Built on the island, for the island.

Tongsai began with a single villa and a simple frustration: quality homes on Koh Samui were being managed like hotel rooms. Owners saw the numbers slip; guests felt the difference.

Today we curate a small portfolio of villas for sale and for rent — every one of them inspected, photographed and managed by our own team. No subcontracted care, no distant call centers.

Whether you are buying your place on the island, renting one for the season, or handing your villa over for management — you deal with people who know it by name.

WHY TONGSAI

Three promises we make to every client.

1

Boutique by design

A limited portfolio means every villa gets senior attention — not a ticket number in a queue.

Owner-first reporting

Clear monthly statements and honest advice — even when the honest advice is "don't buy this one".
