Condo rental management on Koh Samui: letting it yourself or through a manager
You can let a condo on Koh Samui yourself or through a management company. The choice comes down to how much time you have, where you live and how you want to let. This guide covers what managers do, how they charge, what the contract should say and a checklist. It gives no income figures.
You can rent out a condo on Koh Samui yourself, or you can hire a management company to do it for you. At The Astra Samui, You can let your residence yourself or through a rental management company. That is the whole of the official position, and the decision sits with you. This guide helps you make it. It explains what a rental manager does, how managers usually charge, what to put in the contract, and how to run an apartment on an island from a desk in Europe.
We are Varsovia Estate, the sales agent for The Astra Samui. We do not run a rental programme and we do not recommend one management company, so the checklist at the end is neutral. There are no income figures in this guide, and No rental income is promised. There is no hotel programme.
At a glance
- Two ways to let: yourself, or through a rental management company. At The Astra Samui either is possible.
- Letting yourself costs you time and needs a person on the island. A manager costs a fee and takes away most of the daily work.
- A manager’s fee is set by its contract. Models vary, and so does what the fee covers. Compare contracts line by line.
- The contract should say what is covered, what is extra, how and when you are paid, how either side ends it and what happens to the listing.
- Short stays and long leases are treated differently by Thai law and by buildings. Take legal advice and read the building’s rules before you decide.
- Furnish for guests first. Our guide to furnishing a condo for rent has the checklist.
- A calendar with no gaps is not a safe assumption on an island with a rainy season.
Letting yourself or through a manager
The first decision is practical. Ask yourself four things.
- Where do you live? If you are on Koh Samui, or you will be for much of the year, you can meet guests and tenants, let in a plumber and check the apartment yourself. If you are in Europe, you need someone who can act in person within hours, not days.
- How much time do you have? Letting is a service business. Enquiries come at all hours, guests ask for things, the air-conditioning fails on a Saturday.
- How do you want to let? A tenant on a long lease needs little attention after the first month. Short stays mean a changeover every few days, with cleaning, linen and check-ins.
- What do you know about the market? Rates, seasons, platforms and local rules are a body of knowledge. A manager with several apartments has it. You may have to learn it.
Neither route is the cheaper one by default. If you let yourself you save the management fee, but you pay in time and in mistakes, and if you let from abroad you will probably still need to pay someone local for key tasks. A manager costs a fee, but takes on the daily work and gives you a single contact to hold to account.
Letting it yourself
Self-management works best for an apartment you will also use, for an owner who lives on or near the island, or for a long-term tenancy. You need:
- a way to find guests or tenants, such as a platform listing, a local agent or word of mouth;
- someone to clean and change the linen between stays, and someone to hold keys;
- a trusted technician for the air-conditioning, plumbing and electrics;
- a way to be paid, and to pay the building’s bills and utilities;
- an answer to what happens when you are unreachable.
Our guide to furnishing a condo for rent lists what guests expect, drawn from the host guidance published by Airbnb. Whatever you decide, do your numbers first. Our guide on how to calculate rental yield lists the costs, with the fixed charges for The Astra Samui, and gives no forecast.
Using a management company
A manager suits an owner who lives away, who has no time, or who lets to short-stay guests. You hand the work to a company with staff, systems and a list of other apartments. In return you pay its charges, accept its rules on pricing and guests, and depend on its honesty. Choose one on evidence, not on a brochure.
What a rental manager does
A full-service manager typically covers the following. Not every company offers all of it, and some items cost extra, so the contract decides.
| Task | What it involves |
|---|---|
| Marketing | Listing the apartment on platforms and its own site, photographs, descriptions, keeping the calendar current |
| Pricing | Setting nightly or monthly rates for the season and adjusting them |
| Enquiries and bookings | Answering guests, taking reservations, collecting payment and deposits |
| Check-in and check-out | Meeting guests, handing over keys, inspecting the apartment after a stay |
| Cleaning and linen | Cleaning between stays, laundry, restocking supplies |
| Maintenance | Fixing faults, calling technicians, keeping a record of repairs |
| Guest support | Answering calls and messages during a stay |
| Reporting | Statements of income and costs, usually monthly |
| Paperwork | Reports required by the authorities for guests, and local registrations, where they apply |
| Looking after an empty apartment | Airing it, running the air-conditioning, checking for damp |
Ask which tasks the manager does itself and which it passes to a subcontractor, because the quality of cleaning and repairs usually depends on who does the work.
How managers charge
We quote no rates, because we have no sourced figures and rates vary with the manager and the apartment. Managers generally use one of a few models, and a contract may combine them.
| Model | How it works | What to check |
|---|---|---|
| Share of rent | The manager keeps a share of the rent it collects | Is it a share of the rent before or after platform fees, cleaning and taxes? |
| Flat monthly fee | A fixed amount whether or not the apartment is let | Does it cover the empty months, and what does it include? |
| Per booking | A charge for each reservation or each stay | How are long stays and extensions counted? |
| Mixed | A smaller base fee plus a share or a charge on top | Add every part together before you compare |
| Extras | Cleaning, laundry, repairs, supplies, restocking and key handling billed separately | Who sets the price of an extra, and is there a ceiling? |
The point is not which model is cheaper, but what the full charge is for the way you will let. Ask each manager for a sample statement for an apartment of your type, with every deduction shown. If the manager cannot show one, you cannot compare.
Choosing a management company
Find at least three companies and ask the same questions of each. Look for these things.
- A track record you can check. How long has it operated on Koh Samui, how many apartments does it look after, and can you speak to two owners? Names are better than testimonials.
- A registered company. Its legal name, registration and address should match its contract and its bank account.
- The right licences for how you want to let. Whether a licence is needed depends on the kind of letting and on Thai law, so ask the company to show you what it holds and for what activity. Our rule is the same for every apartment: this is a question for a Thai lawyer and for the building.
- Clear reporting. You want monthly statements in a stable format, with each booking and each deduction visible.
- A local team. For repairs, cleaning and guest problems, a manager who has staff nearby reacts faster than a distant office.
- Fit with your apartment. A company with mostly villas may be less suited to a condo, and the other way round.
- How it talks to you. Slow answers before you sign are a warning of slow answers after.
If the project’s sales team recommends a manager, ask what the relationship is, and weigh the recommendation as you would any other. We name no manager and take nothing from one.
The management contract
The contract is where a manager’s promises become obligations. Read it in full and ask for a version in English. If it matters, have a Thai lawyer read it. This is general information, not legal advice. A good contract covers at least the following.
- The parties and the apartment, with the exact unit and the manager’s legal entity.
- Scope of services, as a list, with what is included and what is extra.
- Fees, each one, how it is calculated, when it is charged and any ceiling on extras.
- Authority to spend. The repair amount the manager can approve alone, and above which it must ask you first.
- Payment. How guest payments are collected, where the money is held, when you are paid, in which currency and by what route, and when statements arrive.
- Rates and discounts. Who sets them, whether you can set a floor, and whether the manager may discount.
- Your own stays. Whether you can use the apartment, how to block dates and with how much notice.
- Keys and access. Who holds them, who is allowed in and how entry is logged.
- Inventory. A signed list with photos, so that damage and loss can be traced.
- Guest damage and deposits. Who collects them, who claims, who pays.
- Insurance. What the manager insures and what you must insure.
- Term and ending. The length, how either side ends it, the notice period, and what the manager must hand over on exit: the listing, the reviews, the guest list for future dates and the keys.
- A sale of the apartment. What happens to existing bookings if you sell.
- Disputes. Which law and which place of resolution apply.
Do not sign a contract that you do not understand, or one that is available only in Thai without a translation you can rely on. Do not pay a large upfront fee before you have checked the company.
Long-term or short-term letting
The two ways of letting are different businesses, and the choice affects management, furnishing and risk.
| Long-term letting | Short-term letting | |
|---|---|---|
| Changeovers | Rare | Frequent |
| Management effort | Lower after the start | Higher, continuous |
| Furnishing | Often a simpler fit-out | Guest-ready, with linen and kitchenware |
| Empty periods | Fewer but longer | More and shorter, tied to seasons |
| Rules | A lease between you and the tenant | Stricter in Thailand, and building rules may add limits |
Thai law treats short stays differently from long leases, and a building’s own regulations may limit letting or set a minimum term. We have not confirmed The Astra Samui’s building rules on letting, so we do not describe them. Ask for the draft regulations in writing before you reserve, and put the question about the kind of letting you plan to a Thai lawyer. A manager does not change what the law allows, because it is the apartment and the law that decide, not who takes the bookings.
Building rules and the juristic person
A condominium is run by a juristic person, which sets the house rules and collects the building’s fees. Before you plan to let, ask for the regulations in writing, and check them against your plan. Questions to ask include:
- Does the building allow letting at all, and for what minimum period?
- Do guests or tenants need to be registered with the building, and how?
- Are there rules about noise, luggage, deliveries and access cards?
- Can a manager hold access cards and keys?
- Does the common area fee change if the apartment is let?
- Are there limits on signage, lockboxes or items visible from outside?
At The Astra Samui the building charges are Common area fee: THB 50 per m² per month (12 months paid in advance) and Sinking fund: THB 500 per m², one-off. Both are due however you let, which is why they go into any calculation first.
Furnishing the apartment for rent
A rental apartment is judged by the guest on the first night, so furnish for them first. Linen, towels, kitchenware, small appliances and curtains matter more than decoration. Our guide to furnishing a condo for rent in Thailand has the full list and compares what the standard fit-out covers.
If you want made-to-measure kitchens, wardrobes or interior styling, one route is Livo / Thailand Kitchens, Varsovia Estate’s furniture partner, which has an office and installation team on Koh Samui. We say so because the link is ours, and you should weigh it as a declared link, not an independent recommendation. The lists and options by apartment type are on the furnishing page.
Seasons on Koh Samui
Koh Samui has seasons, and weather is one reason demand and costs are not steady through the year. Our Koh Samui weather by month guide reads the Thai Meteorological Department’s climate normals, in which the last quarter of the year is the wettest. We cannot tell you how that moves bookings, because we hold no occupancy data we trust, and we do not guess.
What you can do is ask. Ask each manager for the occupancy and rates of apartments like yours, month by month, over the last two years, in writing, and treat the answer as that company’s claim. Then test your plan with several months empty. Damp is the other seasonal risk, because a shut-up apartment in a humid climate can turn musty, so ask who airs it and runs the air-conditioning between stays.
For travellers, the practical side matters too: how guests get to the island is covered in our guide to getting to Koh Samui, and the area around the apartment is described in living in Bophut.
Managing remotely from Europe
Many owners at a project like this live abroad, and it can be done. Four things decide whether it works.
- A person in the room. You need someone who can walk into the apartment within hours. That can be a manager, or an agent with a written scope and a spending limit.
- Time zones. Thailand is several hours ahead of Europe. Agree when you can be reached and what the manager may decide without you.
- Money. Agree a bank route for baht, how you receive the net income, which fees the bank takes and which exchange rate applies. Keep your own records, and talk to a tax adviser in both countries.
- Evidence. Ask for photos after each cleaning, an inventory, repair quotes before work and receipts afterwards.
Visit in person after the first few months, check the apartment against the inventory and read a few guest reviews. A manager whose reports match what you see earns your trust. One whose reports do not has told you something important. If you spend part of the year in the apartment yourself and only let it while you are away, read our guide to owning a holiday home in Koh Samui.
The Astra Samui and letting
The Astra Samui is low-rise, resort-style condominium in Bophut on Koh Samui. The project is sold off-plan, with handover planned for December 2028, which is a target and not a guarantee, so the apartments have no booking history. According to the developer, the apartments range over about 26–73 m². Whether you plan to let, live there or both, it is worth understanding how letting would work before you reserve.
See the apartment types for the sizes, the project page for the building and its facilities, and the how to buy guide for the steps from reservation to handover. For the owner’s side in one place, read the investment page. If you want to talk it through, book a call with our team and bring your questions about letting. We will answer what we can confirm and say so where we cannot.
Prices start from THB 3,700,000 (about €98,000, NBP average rate of 23 October 2026).

Questions and answers
How do I rent out my condo in Thailand?
Decide whether you will let it yourself or through a management company, check what the building and Thai law allow for the kind of letting you want, furnish the apartment for guests, set up a way to be paid, and sign a written agreement with whoever finds your tenants. At The Astra Samui you can let the apartment yourself or through a rental management company.
Do I need a rental management company on Koh Samui?
Not always. Letting yourself works if you live nearby or have someone reliable on the island. A manager makes more sense if you live abroad, let to short-stay guests, or do not want to answer calls at midnight. Compare the fee with the time, the risk of mistakes and the months you cannot be reached.
What does a condo management company on Koh Samui do?
Typically it markets the apartment, answers enquiries, checks guests in and out, cleans between stays, handles repairs, collects payment, pays the building’s bills if you ask it to and sends you statements. What exactly is covered, and what costs extra, is set by its contract, so compare two contracts line by line.
How do rental managers charge?
Models differ: a share of the rent collected, a flat monthly fee, a charge per booking, or a mix, with cleaning, repairs and supplies often charged on top. We do not quote rates. Ask each manager for the full list of charges in writing and for an example statement.
Can I manage a Thai condo rental from Europe?
Yes, if you have a local person who can act in person: a manager, or a trusted agent with a written scope. Plan for the time difference, a bank route for payments in baht and a way to approve repairs quickly. Check that someone looks after the apartment when it is empty.
Is it better to let a condo long-term or short-term?
Neither is better in general. A long tenancy means fewer changeovers and less management, but rent depends on the market and on how long the tenant stays. Short stays can mean more work and more empty days, and Thai law and the building’s rules may restrict them. Take legal advice before you choose.
