Koh Samui Villas: What to Know Before Buying

Most people start looking at Koh Samui villas with a photograph: a pool on a green hillside, the bay below, perhaps another island on the horizon. The view is real, and it is the reason the island attracts villa buyers. But the photograph leaves out the things that decide whether owning the house is a pleasure or a chore: the road up to it, the water supply, the person who checks on it in the rainy months and the paperwork behind the land. This article goes through them in the order they tend to come up.

We quote no prices, rents or yields here. Current prices and availability come from a manager, and any rental figure we give is an agency estimate with its source and date.

An island means a journey, for you and for everything else

There is no bridge to Samui. You arrive either by air, through the island's own small airport, or overland to the coast and then by ferry. Both work well, but each visit is a trip to plan rather than a drive, and that matters more than it seems when you own a house there.

Building materials, furniture, spare parts for a pool pump or an air-conditioner usually come over by sea too. Ask the developer how long typical repairs and replacements take on the island, and whether the estate keeps common spare parts on hand. If you plan to fly in for a viewing, try to see several villas in one trip; a manager can help you group them by area so you are not crossing the island back and forth.

Pick the area before the villa

Samui is small enough to drive around, yet its coasts feel quite different. Chaweng on the east is the busiest, with the best-known beach, hotels and nightlife, and the most tourist traffic. Lamai, further south, is calmer and more local. Bophut on the north coast, around Fisherman's Village, is where many people settle for longer stays, and Maenam, to its west, is the quietest stretch of the north. Many villas with views are built on the hills above these beaches rather than on the beaches themselves.

We do not yet have separate pages for each part of the island; all our Samui projects, with a short guide to the areas, are on the Koh Samui property page. Start by deciding what you want within reach without a car: a beach, restaurants, a supermarket, a school. That usually narrows the choice to one or two coasts.

The hill, the road and the water

The best views are on slopes, and slopes come with roads. Some access roads to hillside villas are steep and narrow, and they behave very differently after heavy rain or after dark. Before you commit, drive the road yourself in an ordinary car, not only in the developer's vehicle, and ideally after rain. Picture a delivery truck, a taxi at night, or elderly parents walking down to the gate.

• Who maintains the road: the estate, the local authority or nobody in particular?
• How rainwater runs off the plot, and whether there are retaining walls or signs of erosion on the slope.
• Where the water comes from, how it is stored, and what happens in a dry spell.
• How the villa is connected to electricity, and whether the internet connection is good enough to work from.
• What can be built on the plots around you, and whether that could block the view you are paying for.
• How many stairs there are between the parking, the house and the pool.

Our page of Koh Samui villas for sale helps you compare the choice between a hillside view, a walk to the beach and a quiet inland plot, and shows what to look for on each project page.

Looking after a villa from a distance

Humidity, heavy rain, strong sun and insects work on an empty house all year. A pool needs regular care, a garden grows quickly, air-conditioners need servicing and closed rooms can develop mould. With a condo, the building takes care of much of this; with a villa, it is your responsibility, so arrange it before you buy, not after the first bad surprise.

In a managed estate, the management company looks after the shared areas and sometimes offers to look after individual villas too. For a standalone villa you appoint a management company or separate people for the pool, garden and cleaning. Either way, ask for a written agreement that says who holds the keys, how often someone visits, what a regular report with photos includes, who pays the bills while you are away, and up to what amount repairs can go ahead without asking you. The running costs to budget for are listed in our guide to ongoing costs of owning a condo or villa.

If you plan to let the villa while you are away, note that short-term letting is regulated separately in Thailand and estates have their own rules. What a specific villa allows is a question for a Thai lawyer. The practical side, from choosing a manager to the management agreement, is covered in renting out and managing your property.

Seasons: the island has its own calendar

Samui sits in the Gulf of Thailand, on the opposite side of the peninsula from Phuket, and its rainy season does not fall at the same time as Phuket's. If you are comparing the two islands, do not assume the weather you know from one applies to the other.

For a buyer, seasons matter in three ways. First, they shape when you will want to use the villa yourself. Second, they shape rental demand: holiday guests come in waves, and there are quieter stretches in between. Third, the wet months are when roads, drainage and roofs are really tested. If you can, see the villa once in the busy season and once in the rainy one, or at least ask the estate's current owners how the house coped through the last wet season.

The land under the villa: a question for a Thai lawyer

Buying a villa is not the same as buying a condo unit, and what a foreign buyer actually holds depends on the specific property and contract. Do not rely on a brochure, a sales presentation or on us for the answer. Have an independent Thai lawyer check the land documents and the contract before you pay any deposit. The basic terms are explained in our guide to foreign ownership in Thailand, which is a good place to start before you speak to a lawyer.

When you are ready, tell a ROMA ThaiProperty manager how you plan to use the villa, whether for your own holidays, for letting or for long stays. They will shortlist projects across the island, confirm current prices and availability with the developer, describe the road up to each villa, and pass the developer's documents on to your lawyer.
