Samui and Phangan Rise as Thailand's Next Island Property Plays

Buyers scouting Thai island property beyond Phuket now have a credible second front. Colliers Thailand has flagged Koh Samui and Koh Phangan as the country's fastest-moving resort markets, with foreign interest, land prices and project pipelines all tracking upward.

The shift matters for international purchasers because it widens the menu of branded and boutique options in a segment that until recently was concentrated almost entirely on Phuket. Samui, with its established airport and hotel infrastructure, is attracting higher-end villa and residential launches aimed at long-stay foreign owners. Phangan, historically associated with backpacker tourism and wellness retreats, is being repositioned as a quieter, lower-density alternative with stronger upside on land.

Colliers points to rising transaction volumes and a pipeline of new developments coming to market over the next two years. Land values on both islands have climbed sharply, reflecting both speculative buying and genuine end-user demand from buyers relocating from Europe, Hong Kong and the mainland. The wellness-led tourism narrative, particularly around Phangan, has helped justify pricing that would have looked aggressive a few years ago.

For foreign buyers, the structural caveats remain familiar. Direct land ownership is not available, so most acquisitions are structured through condominium quotas, long leases or villa arrangements held via Thai entities. Due diligence on title, zoning and beach access rights is more involved on the islands than in Bangkok, and infrastructure (water supply, road access, waste) varies sharply between micro-locations.

The broader read: Thailand's island residential market is decentralising. Phuket retains scale and liquidity, but Samui and Phangan now offer the combination of price growth, supply and lifestyle positioning that earlier-stage investors tend to look for.
