Property on Koh Samui

Koh Samui is Thailand's second-largest island by area and one of the few property markets in the region with fully developed infrastructure, its own airport and stable foreign demand. If you are looking for Koh Samui property - whether as a place to live or as a capital investment - this guide will help you understand the island's character, its market and the rules of buying. Twins Real Estate does not run its own development projects on Samui, but as a European agency we also advise buyers on this island - in your own language and with no commission on your side.

Profile of the island - the Gulf of Thailand, a different climate

Koh Samui lies in the Gulf of Thailand, off Thailand's east coast - in terms of geography and character it is an entirely different world from Phuket, which sits in the Andaman Sea. This difference is not just topographical: it directly affects the climate, the rainy seasons and the rhythm of life on the island.

The rainy season on Koh Samui falls mainly in October, November and December - the opposite of Phuket, where heavy rainfall is characteristic of the May-October period. This means that Samui can be calmer and sunnier at the turn of the year, when Phuket is ending its season. For investors thinking about short-term rental, this difference has real significance when calculating occupancy.

The island has its own airport (Samui Airport, a private airport operated by Bangkok Airways), which is both an advantage and a limitation - tickets are often more expensive than flights to Phuket. An alternative route is by ferry from Suratthani - longer, but cheaper. From the island you can also easily reach Koh Phangan (known for the Full Moon Party) and Koh Tao - one of the best diving areas in Southeast Asia.

Main areas: where to look for property on Koh Samui

The island is large enough that its various parts have a distinct identity and varied prices. Knowing the character of each area is essential before deciding to buy.

Chaweng - the centre of life and commerce

Chaweng is the island's most developed area, with the longest beach on Samui, a full retail base, restaurants, bars and nightlife. Its great tourist popularity translates into good short-term rental, but property prices here are among the highest. Chaweng works well for investors focused on holiday rental - less so for those seeking a quiet, residential environment.

Lamai - beachside balance

Lamai is Samui's second-longest beach and the second-largest tourist area - popular, but calmer and more family-friendly than Chaweng. The infrastructure is well developed and property prices are somewhat lower. A good compromise between accessibility and quiet.

Bophut and Fisherman's Village - atmosphere and class

Bophut, and in particular its heart - Fisherman's Village - is one of the most distinctive locations on Samui. Heritage buildings along the waterfront, fashionable restaurants, boutique hotels and a weekly walking street. Popular with European buyers seeking authenticity without giving up comfort. The market here is dominated by villas and houses, with many sea-view properties.

Maenam - the peaceful north

The island's north coast, with a long stretch of beach and a gentler pace of life. Maenam is a choice for families and remote workers - less traffic, lower prices, the calm waters of the bay. The view of Koh Phangan gives this place added character.

Choeng Mon - prestige and privacy

Choeng Mon, on the northeastern tip of the island, is regarded as one of the more exclusive locations. The beaches here are more intimate, the waters calmer, and the properties are often private residences and luxury villas with a pool. Proximity to the airport and Chaweng while retaining greater privacy is the main argument for buyers in this area.

Koh Samui vs Phuket - differences that affect decisions

Both islands are popular, both have an international property market and well-developed infrastructure. But they differ in several key respects that should shape your decision:

• Market size: Phuket is much larger - more developments, greater turnover, a shorter average resale time. The Koh Samui market is mature, but smaller and less liquid.
• Air connections: Phuket has an international airport with direct connections from Europe. To Samui you fly via Bangkok or Kuala Lumpur - convenient, but usually more expensive and with a connection.
• Rainy season: In Phuket it is rainy from May to October; on Samui - from October to December. For investors letting property this is a concrete difference in calculating seasonal occupancy.
• Price points: Villas on Koh Samui are often cheaper than equivalent properties on Phuket's west coast (e.g. Surin, Bang Tao). The difference can reach 20-40% for a comparable standard - which is a significant argument for buyers with a higher budget who nonetheless value savings.
• Character: Samui is more island-like and relaxed; Phuket - more dynamic, with a larger business centre and a wider range of international services.

If you are also considering other destinations in southern Thailand, it is worth looking at our guide to property in Krabi - a calm, picturesque market with its own character and a different buyer profile.

Prices and the market for villas and apartments on Koh Samui

The Koh Samui market is dominated by villas - detached houses with a pool, often with a view of the sea or the island's hills. Apartment buildings exist, but their supply is far smaller than in Phuket, and the offer is less varied in terms of price.

Indicative price ranges

• Apartments (freehold, 1-2 bedrooms): from around 3-6 million THB depending on location and standard
• 2-bedroom villas with a pool: from around 6-10 million THB; mid-range from 8 million THB
• 3-4 bedroom villas, better locations: around 12-22 million THB
• Premium residences and sea-view villas: from 25 million THB upwards

Prices are indicative and depend on the property's technical condition, location (beach access, view), form of ownership and the current market climate. A detailed breakdown of transaction costs - transfer tax, stamp duty and other fees - is discussed in our guide to the property market in Thailand.

An important note: market liquidity on Samui is lower than in Phuket. The time needed to resell a property can be noticeably longer. If you are planning an investment with a view to short-term resale, factor this in at the purchase stage.

Who villas and apartments on Koh Samui are for

Koh Samui is not for everyone - and that is part of its charm. The island best suits specific buyer profiles:

• Those seeking an authentic island atmosphere - less corporate than Phuket, more relaxed, with a distinct character to each area
• Buyers focused on villas with a pool - the dominant type of property; a good choice for those who value privacy and space
• Investors calculating holiday rental - good occupancy in the high season (January-March, July-September), but the seasonality is clearly felt
• Higher-budget buyers seeking better prices than on Phuket's west coast - Samui can be an interesting price alternative at a comparable standard
• Families and people planning a longer stay: the medical and educational infrastructure is developed enough to live here for the long term

The rules of buying for a foreigner

The rules on buying property by foreigners are identical on Koh Samui to those throughout Thailand - the island is not subject to any separate regional regulations.

In practice this means:

• Apartments (condominiums): a foreigner can own a unit on a freehold basis, provided that foreign buyers together do not exceed 49% of the usable floor area in a given building. This is the cleanest form of ownership available to foreigners.
• Villas and houses on their own land: the land cannot formally be in the full ownership of a foreigner. In practice two main solutions are used: leasehold (a 30-year lease with an option to extend) or acquisition through a Thai limited liability company (Thai Limited Company), which requires an appropriate legal structure and advice.

You will find the legal details, risks and recommendations for both paths in our article can a foreigner buy property in Thailand. The rules described in that article cover the whole country, including Koh Samui.

Whichever path you choose: always use an independent Thai lawyer specialising in property law. This is an essential part of due diligence, not an unnecessary expense.
