The Gulf island east of Surat Thani, served by its own airport and a ring road: Chaweng and Lamai on the busy east coast, Bophut and Maenam on the north shore, Choeng Mon on the north-east cape and the quiet west coast around Taling Ngam. Villas outnumber condos and go through leasehold or a Thai company; many catalog rows carry only the island name, which is why this island-level page exists alongside the beach pages.

Daily rental for stays under 30 nights falls under Thailand’s Hotel Act and generally needs a hotel licence or a qualifying exemption. Brixfox never claims a listing is licensed for short-term letting; every listing carries the warning and the building’s or estate’s position must be verified before underwriting nightly income.
Foreign buyers own condominiums freehold within a building’s 49% foreign quota; villas are held on a registered 30-year leasehold or through a Thai company. The ownership route changes what a yield is worth, and it is shown per listing.
Many listings are geocoded to an area or neighbourhood centroid rather than the exact plot (recorded per listing as location precision), so distances and map positions here are approximate.
Matched on the listing's stated area; a villa described as two areas can appear under both. Prices in USD as listed.
