Long-stay rentals here on Koh Samui operate differently from short holiday lets. If you are planning to stay for a month or more, you will find that prices are lower, owners are more willing to negotiate, and the whole process has its own rhythm. Our team has been on Samui since 2009 and works with these rentals daily. This guide takes you through it step by step.

1. Budget and duration

The first question any owner will ask you is: how long? Duration directly affects the price. Stays of three months or more typically attract a 10–20 per cent discount against the monthly rate, and some owners negotiate further if you pay several months upfront.

Current market ranges on Koh Samui (2026):

Property type Monthly range
Studio or 1-bedroom apartment ฿8,000–20,000
2–3 bedroom house ฿20,000–45,000
3–4 bedroom pool villa ฿40,000–120,000+

A family of four looking for a 3-bedroom house with a pool in Lamai or Maenam should budget around ฿45,000–70,000/month. Properties in Chaweng or those with direct sea views tend to run 20–40 per cent higher for comparable space.

2. Choosing your area

Samui is a small island — roughly 247 km² — but the districts differ considerably.

Chaweng is the commercial centre. International schools, Bangkok Samui Hospital, supermarkets, and restaurants are all within easy reach. It is the liveliest and least quiet part of the island.

Lamai is quieter than Chaweng while still offering solid infrastructure. It is popular with long-stayers who want a balance between convenience and calm.

Bophut (Fisherman's Village) has a charming waterfront feel with a distinctly European character — good restaurants and cafés, though the rental inventory is smaller than Chaweng's.

Maenam on the quiet northern coast suits remote workers well: a long beach, fewer tourists, and lower prices than the east side.

Nathon is the island's administrative centre and ferry hub. Rents are cheaper, the atmosphere is local, and international tourists are rarely seen here.

Choeng Mon on the eastern tip is calm and family-friendly, with several well-maintained villas.

Taling Ngam on the west coast offers views across to the Ang Thong archipelago and a genuine sense of remoteness — suited to those who actively want to be away from the island's busier areas.

If your children will be attending school, check distances to the main international schools before committing to a district; most are clustered around Chaweng and Lamai.

3. Finding a property

Long-stay rentals on Samui circulate through several channels. Dedicated rental portals provide the most structured search: district filters, rental type, and up-to-date listings. Facebook groups and Telegram channels carry a live stream of offers but without filtering — photos and prices are not always current, and availability needs personal confirmation. Word of mouth within the island's expat community also turns up good options before they are publicly listed.

Whichever channel you use, establish early on whether you are dealing with the owner directly or a management company acting on their behalf. Both arrangements are normal and legal, but knowing who signs the lease and who is responsible for repairs and the deposit avoids confusion later.

4. What to inspect before you sign

Even a well-presented property deserves a personal walkthrough. A few things to check on the spot:

Air conditioning. In a tropical climate, air conditioning runs year-round. Ask how old the units are and whether routine servicing is included in the rent.

Water pressure and hot water. Some properties use solar heaters: cold water in the morning, hot by midday. Not a problem if you know in advance.

Internet speed. Run a speed test during the visit. For remote work, aim for at least 30–50 Mbps. Samui has 3BB, True, and AIS Fibre; find out which provider is installed.

Deposit and return terms. The standard deposit is one to two months' rent. Make sure the return conditions are set out in writing, not just mentioned verbally.

Utilities. Clarify whether electricity and water are included in the rent or billed separately. The municipal electricity rate runs around 4–5 THB per kWh; some owners charge a small markup, which is both legal and common on Samui — but fix the rate in writing before signing.

5. The lease

Rental contracts here are typically in English, sometimes alongside a Thai version. Key points to review before signing:

Early termination. What happens if you need to leave before the term ends? Is any part of the deposit recoverable?

Pets. If you have an animal, confirm this before any other agreement is made.

Repairs and wear. Minor day-to-day maintenance generally falls to the tenant; major repairs to the owner — though the line between the two is interpreted differently by different owners. Put it in writing.

Subletting. Thai property law does not permit subletting unless it is explicitly agreed in the contract. If long-term guests are a possibility, discuss it upfront.

If the contract is in Thai only, ask for a translation or bring a local contact who can walk you through it. Understanding the core clauses protects you at check-out.

6. Move-in

On the day you arrive, photograph every room and send the full set to the owner or manager via messaging — dated and time-stamped. This is your record if any damage dispute arises at check-out.

Note the electricity and water meter readings. Confirm who to contact for maintenance and whether there is an out-of-hours number for urgent situations.

Samui's rental market is long-established. Most owners here have years of experience renting to international long-stayers and are generally straightforward to deal with. The situations that become complicated are almost always those where terms were left vague at the start. Get the basics in writing on day one, and the rest tends to look after itself.
