Why Investors Compare Koh Samui for Real Estate Investment
Koh Samui is a smaller, villa-led island market than Phuket, with a higher average price per unit and a shorter, more seasonal rental calendar. Investment is concentrated in beachfront and sea-view villas in Lamai, Chaweng and Maenam, alongside a growing condo segment aimed at foreign freehold buyers.
Independent data on actual rents against sale prices is more reliable here than developer projections: net yields of 12% to 25% are commonly advertised but not supported by independent analysis, which instead points to roughly 6% to 8% in the island's stronger areas. Recent supply growth in villa rentals is also worth weighing against any yield projection. Investors comparing Koh Samui against Phuket or Pattaya should budget for higher airfares via Samui's privately operated airport.

Koh Samui Investment FAQ
What does property cost per square metre on Koh Samui?
One 2025 industry report puts the median condo sale price on Koh Samui at around 88,500 THB per square metre. Villas are usually priced per project rather than strictly per square metre, with off-plan pool villas commonly listed in the 70,000 to 75,000 THB per square metre range in recent listings.
What rental yield is realistic on Koh Samui?
Independent analysis of actual rents against sale prices puts net yields around 6% to 8% in strong areas like Lamai, Chaweng and Maenam. Developer and listing marketing sometimes claims 12% to 25%, but those figures are projections, not measured returns, and should be treated with caution.
Is there an oversupply risk for villas on Koh Samui?
Independent villa rental supply on Koh Samui grew by 34% year-on-year as of early 2025, and average nightly rates fell 11% over the same period even as occupancy rose to about 71.5%. That combination points to more competition between villas for each booking, which is worth factoring into any yield projection.
How do I get to Koh Samui, and does that affect costs?
Koh Samui Airport (USM) is privately operated and typically has higher airfares than Thailand's mainland airports, which can affect short-term tourist flow compared with Phuket or Pattaya. Some travellers also reach Samui by ferry via Surat Thani, which is slower but cheaper.
Can foreigners buy a villa on Koh Samui the same way as a condo?
No — the condo freehold route (up to 49% of a building's floor area) does not apply to villas or land, since foreigners cannot own Thai land freehold. Most Koh Samui villa buyers use a registered leasehold or a Thai company structure, the same options used for villas across Thailand.
