Buying a Business in Koh Samui: Buy the Booking Calendar, Not the Dream

Yes, if you want margin over volume, and no if you are chasing cheap mass footfall. Surat Thani province, which covers Koh Samui, Koh Phangan and Koh Tao, drew about 3.21 million foreign tourists in the first nine months of 2024 according to the Ministry of Tourism and Sports. That is a fraction of Phuket's numbers, but it is a well-heeled fraction. The people who come here are not backpackers counting baht in a Chaweng hostel. They are couples and families paying premium nightly rates in Bo Phut and Maenam.

The reason the market skews rich is boring and structural: the airport. Samui's airport is largely served by Bangkok Airways, which owns the field and prices flights accordingly, so getting here costs more than a budget hop to Phuket or Krabi. That keeps the casual crowd away and self-selects for visitors with money to spend. The island leans into boutique resorts, wellness retreats, and private villas rather than 400-room concrete boxes. If your business model needs high spend per head instead of high headcount, Samui is built for you.

So when I invest in Koh Samui, I am buying access to a smaller, richer, less price-sensitive customer than I would find almost anywhere else in the Gulf. That is the whole thesis. You are not competing on being the cheapest. You are competing on being the one they remember and rebook.

Buy something with a customer list you can inherit, and avoid anything that depends on you personally being charming at reception. The businesses that work on Samui are the ones that keep earning while you sleep or fly home for a month. A boutique resort for sale in Samui with real booking history, a wellness or yoga studio with a paying membership base, and a villa-management book with signed owner contracts are the three I would look at first. All three come with something you can verify: recurring revenue from repeat clients.

F&B is the seductive one and the one I would treat with the most suspicion. A cafe on Fisherman's Walk or a beach restaurant in Lamai looks like a lifestyle, and mostly it is a way to convert your savings into other people's meals. Margins are thin, staff turnover is high, and half your year the tables are empty. I am not saying never buy F&B. I am saying buy the one with two years of daily till data showing it survives the low season, not the one that opened in January and is being flipped in April before the owner sees July.

Dive and marine businesses are a real niche, but Koh Tao is the dive capital of the Gulf, not Samui, so a Samui dive operation is usually a day-trip feeder rather than the destination itself. Island services, laundry, transfers, pool maintenance, villa cleaning, are unglamorous and genuinely good cash businesses if they already hold contracts with a dozen villas. Nobody dreams of buying a pool-cleaning route. That is exactly why it is often the smarter buy.

Because on Samui you are almost never buying land, you are buying time on someone else's land, and if the lease is short or shaky the business is worthless the day it expires. The lease is the deal-killer. I have seen people fall in love with a resort's revenue and gloss over a lease with four years left and no renewal clause, which means they are buying a business that legally evaporates before their loan is paid off. The building can be perfect and the bookings can be full, and none of it matters if the ground under it goes back to the landlord in 2030.

Thai land leases are commonly written as an initial term of up to 30 years, sometimes with promised renewals that are not automatically enforceable the way a Western buyer assumes. What you want to see is a long registered lease, ideally freshly cut, with the remaining term long enough to justify the price and clear, written renewal mechanics. A licensed Thai lawyer reads that lease before you fall in love, not after you have wired a deposit. This is the one line item where I refuse to save money on legal fees, because it is the one that can zero out the entire purchase.

Check who actually holds the head lease too. On some Samui properties the operator you are buying from is a sub-tenant, and you are inheriting a sublease sitting on top of a lease you never get to read. Untangle that chain fully, in writing, before you sign anything.

You can own the business and the building's operation, but you cannot own the land, full stop, and anyone who tells you otherwise is either lazy or about to get you in trouble. Foreigners cannot own land in Thailand. Full stop. On Samui that means villas and resort plots are held on long leasehold, or through legitimate lawyer-structured arrangements, and the honest ones are transparent about exactly which. When someone waves away your ownership question with a smile, that is your cue to slow down, not speed up.

The illegal shortcut you will be offered, sometimes casually over a Chang at Fisherman's Village, is the nominee structure: a Thai company where Thai shareholders hold the majority on paper but exist only to let a foreigner control land they cannot legally own. Nominee arrangements are illegal in Thailand. Do not do it, do not let a broker talk you into it, and walk away from any seller whose whole deal rests on one. When the authorities unwind a nominee, you do not lose a fee, you lose the asset. A proper Thai lawyer will structure the deal a legal way or tell you the deal cannot be done, and both of those answers are worth paying for.

The practical upshot: budget for real legal structuring, price the leasehold nature of the asset into what you offer, and treat any seller pushing nominees as a seller hiding other problems too.

Brutal enough that it is the single most common thing new owners underestimate, and it runs on a different calendar than the rest of Thailand. Samui sits in the Gulf, so its high season runs roughly December to April, which is not the same rhythm as the Andaman coast around Phuket and Krabi. If your mental model of Thai tourism was built on a Phuket calendar, throw it out. The Gulf has its own weather and its own peak, and the shoulder months in between can be quiet in a way that empties a poorly capitalised business.

That mismatch cuts two ways. The upside is that Samui can catch travelers when the Andaman is rained out, so a well-run place picks up some counter-seasonal demand. The downside is that your fixed costs, staff, lease payments, electricity for the pool and the air conditioning, run all twelve months while your revenue crams into a handful of them. I underwrite every Samui deal on the low season, not the high one. If the business only makes sense when Chaweng is full in February, it does not make sense.

The businesses that die here are the ones that opened in peak season, saw three good months, and assumed that was the year. Then June arrives, the bookings thin out, the wage bill does not, and the founder who put their whole nest egg into a wellness retreat is suddenly listing it as a business for sale in Koh Samui at a loss. Their capitulation is your opportunity, but only if you priced the low season in from the start.

It is worth a multiple of its proven, repeatable net profit, not a multiple of the owner's hopes or the cost of the furniture. I value a boutique resort for sale in Samui on trailing twelve-month net earnings, adjusted for the lease term remaining, and I discount hard for anything I cannot verify with bank records. A tired seller will quote you a headline revenue figure and a gross number that quietly forgets the low season, the staff costs, the commission Booking.com and Agoda skim off the top, and the lease payment. Strip all of that back to real owner earnings before you talk price.

Watch the online travel agency dependency closely. A resort in Bo Phut that gets 90 percent of its bookings through Agoda and Booking.com is renting its customers and handing over 15 to 25 percent per reservation, and that book of business walks the day a bigger competitor outbids it on the platform. A resort with a direct-booking list, returning guests who email the manager by name, and a healthy repeat rate is worth materially more per baht of revenue, because that revenue is defensible. When you invest in Koh Samui, you are really paying for how sticky the customers are.

Furniture, fixtures and a nice website are worth almost nothing on their own. I have seen sellers price the linens and the sunbeds like they are gold. The asset you are paying for is the cash flow and the lease that protects it. Everything else is decoration.

Buy the proven booking history every single time, and let someone else fund the education of building from scratch. This is the core of everything I believe about buying a business in Thailand as a foreigner: the market does not reward your dream, it rewards a track record. A wellness retreat in Maenam with three years of occupancy data, a mailing list of past guests, and a repeat-booking rate you can verify is a business. An empty plot with a mood board and a founder who did a yoga teacher training in Ubud is a very expensive hobby.

The build-it-yourself route on Samui looks cheaper on the spreadsheet and never is. You underestimate the permits, the contractor who vanishes at 70 percent complete, the ramp time before Google and the OTAs trust a brand-new listing, and the first low season with zero reputation and full costs. By the time you have a booking calendar worth anything, you have spent more than the going-concern business you dismissed as overpriced, and you have burned two years finding out what its numbers already proved.

I am not romantic about this. The most profitable move I have watched on Samui is buying the exhausted founder's proven business at a low-season discount, keeping the staff and the repeat guests, and simply running it competently. Boring, provable cash flow beats a beautiful story with no revenue in every deal I have ever seen close well.

You verify it against money that actually moved, never against a spreadsheet the seller typed the night before you visited. Occupancy is the number sellers massage most, so I refuse to accept a claimed figure I cannot tie to bank deposits, the OTA extranet, and the property management system all at once. Ask for read access to the Booking.com and Agoda dashboards and cross-check the reservation history against twelve months of bank statements. If the deposits do not match the story, the story is the lie.

Pull the property management system export and look at the low season specifically. Anyone can fill rooms in Chaweng in January. I want to see what June, September and October actually did, because those months tell me whether this business survives a year or just a peak. Ask for the repeat-guest rate and the direct-versus-OTA split, then sanity-check it against the guest emails and the mailing list size. A seller who genuinely has a loyal book will hand this over without drama. A seller who stalls is telling you what you need to know.

Then do the unglamorous physical checks. Sit in the cafe or the resort lobby across a couple of different days and count the actual guests. Talk to the staff about how busy the shoulder months really get. Walk the villa book and confirm the owner contracts are signed and current, not verbal handshakes that leave when the manager does. And run every number and every document past a licensed Thai lawyer and a local accountant before money changes hands, because on Samui the paperwork is where the deal is really won or lost.

You find the good ones through people, not billboards, because the best Samui businesses sell quietly before they ever hit a public listing. The genuinely strong resorts and villa books often trade through word of mouth among operators in Bo Phut, Maenam and Fisherman's Village long before a sign goes up. That is why building relationships on the island, with managers, lawyers, and other owners, surfaces deals a cold search never will. The listings you see plastered everywhere are frequently the tired F&B places on their third owner in five years.

That said, you still want a proper marketplace to see what is actually trading and to benchmark asking prices, and AcquireThai lists real Koh Samui businesses for sale so you can compare boutique resorts, wellness studios, villa-management books and island services in one place instead of chasing broker rumours around Chaweng. Use it to learn the market and spot the serious sellers, then do the deep diligence yourself on the lease and the occupancy.

The one-line summary of everything above: on Samui, buy a business that already earns, insist on a long clean lease your lawyer has read, verify the low-season occupancy against real bank deposits, refuse every nominee structure you are offered, and let the founders with beautiful mood boards and empty calendars fund your competition. Do that, and Koh Samui is one of the best islands in Thailand to own a business. Skip it, and you become the cautionary tale I tell the next buyer.
