Koh Samui sits at the premium end of Thai island living. Higher rents, expensive electricity, and a tourist-priced food scene push costs well above Chiang Mai and even Phuket in some cases. However, the island's lush scenery, well-developed expat infrastructure, and year-round warmth attract a growing number of long-stay residents willing to pay the premium. Bophut and Maenam in the north, and the Lamai area in the south, offer the best value for residents who are not tied to Charnvee or Bang Rak's higher-priced strips.
