Rental Yield in Thailand: Gross, Net and What “Agency Estimate” Means

If you are looking at a Thai condo as an investment, the first number you are likely to be shown is a yield. It is the easiest figure to print and the hardest to check before the unit has been let for a while. This guide gives no percentages and no forecasts. It explains how any such number is built, what should come off it, and what to ask before you rely on it.

This is general information, not investment, legal or tax advice. Rules on letting, tax and the market itself change, and decisions about a specific unit belong with a Thai lawyer and your own tax adviser.

The short version

• A yield figure describes a calculation, not the apartment. Change the assumptions and the number changes.
• Gross yield ignores costs. Net yield is what matters, and the gap between the two is where most surprises live.
• Short-term and long-term letting are different businesses, and short-term letting has its own legal rules in Thailand.
• A developer’s rental guarantee is a contract. Read it with a lawyer, and look at who stands behind it.
• Any yield figure from us is labelled “agency estimate”, with a source and a date. By default, the site does not publish yield figures at all.

What “agency estimate” means

We start here because it shapes how you should read every number that follows, from anyone. When we give a yield figure, it carries the label “agency estimate”. That label is not decoration. It says the number is someone’s estimate, made on a particular date, under particular assumptions. It is not a property of the unit and it is not a commitment.

A fair estimate comes with three things attached:

• Source: where the number comes from, such as the developer’s marketing material, figures from a management company, or a comparison with similar units. A developer’s figure is a seller’s position, and worth reading as one.
• Date: the day it was true. Rental markets move, and an undated number slowly turns from an estimate into a promise nobody made.
• Method: gross or net, short-term or long-term letting, what occupancy was assumed, and which costs were deducted.

What this site shows, and what it does not

A project page shows facts, and only when the field has been filled in: construction status and the planned handover quarter or year, distance to the sea, the common fee in baht per square metre per month, the payment plan, and the foreign quota. Yield figures such as ROI, IRR and cap rate are not published on the site by default. If they ever are, they will appear only with the “agency estimate” label and the source and date next to them. If one of our managers mentions a figure in conversation, ask for the same three things: source, date and method.

Gross yield and net yield

Gross yield is a year’s rent divided by the purchase price, before any costs. It is quick to work out and easy to compare across projects, which is why it is the number that usually appears in brochures and listings. It answers the question “how much will tenants pay?”, not “how much will you keep?”.

Net yield is a year’s rent after the owner’s costs, divided by everything you actually put in. That second part matters as much as the first. The total includes the price, the fees and taxes at registration, the sinking fund and advance service charges collected at handover, furniture and appliances, and the cost of moving money. Our guide to taxes and fees lists the purchase costs in full.

When the money goes in matters too

If you buy off-plan, you pay in instalments during construction and the unit earns nothing until handover. Comparing it with a finished unit that is already let means accounting for the time until handover. How instalments are usually structured is covered in the guide to developer payment plans.

ROI, IRR and cap rate

You will meet these in investment presentations. Cap rate is essentially net operating income for a year divided by the property’s value, ignoring any loan. ROI, return on investment, compares what you made with what you put in, and sometimes includes price growth. IRR adds time: when each payment went out and when money came back, which makes it very sensitive to the assumed future sale price. All three are legitimate tools. Each is exactly as good as the assumptions inside it, and a figure without those assumptions tells you very little.

From gross to net: what comes off

The simplest way to see a real yield is to build a yearly table yourself: expected rent at the top, then one line for each cost. These are the lines that almost always belong there.

Vacancy

No unit is let every day of the year. Long-term lets have gaps between tenants, and sometimes a refresh before the next one. Short-term lets have a high season and a low season, and even in high season not every night is booked. A calculation that assumes full occupancy all year is really gross yield in disguise.

Management

If you live abroad, a management company finds tenants, checks them in, cleans, handles repairs and sends a statement and payment, for a fee. Fees vary between companies and between short-term and long-term letting, so it is worth knowing exactly what the fee covers and what is billed separately. How to choose a company and what to check in its agreement is the subject of our guide to rental management.

Common fee

Condo owners pay a common fee to the building’s juristic person for security, cleaning, the pool, lifts and shared areas. It is due whether the unit is let or empty. A project page lists it under “Common fee”, in baht per square metre per month, when the field is filled in — the one line in your table you can be fairly sure of. Turning that rate into a yearly figure for your unit is covered in our guide to the costs of owning a condo or villa.

Wear, repairs, insurance and utilities

A rental unit needs furniture and appliances, and they wear out, faster when guests change every few days. Air conditioners, fridge, washing machine, linen, paint: set aside a sum each year rather than discovering the cost mid-season. The building insures common areas; contents and liability towards tenants are insured separately. With short-term letting, electricity and water are usually yours, and in empty months they always are. The full picture of running costs is in our guide to ownership costs.

Tax

Rental income from a Thai unit can be taxable in Thailand even if you do not live there, and Thailand also has an annual land and building tax that depends partly on how the property is used. The country where you are tax resident will have its own view of the same income. The Thai side is outlined in the guide to taxes and fees; your own figures belong with a tax adviser, not with us.

Currency and transfer costs

Rent arrives in baht, and you probably count in another currency. Exchange-rate movements change your yield in your own currency even when the rent in baht has not changed, in either direction. Every transfer between countries also carries fees and a spread. Our guide to transferring money to Thailand explains the route the money takes.

Long-term or short-term letting

The two models differ in almost everything except the address.

• Long-term letting: one tenant, a lease, less turnover, less cleaning and less wear. Income is steadier and more predictable, without the peaks of high season.
• Short-term letting: changing guests, cleaning and linen, seasonal pricing, bookings through platforms that take a commission. In a good season income can be higher, but so are costs, the workload for the manager and the dependence on tourism.

Neither is “right”. The question is what suits you: whether you want to use the unit yourself for a few weeks a year, how much variation in income you can live with, and what the building allows. If you want to combine personal use with letting, check that the management company’s model permits it.

The legal side of short-term letting

Short-term letting in Thailand is regulated separately from ordinary leases. It is connected to the Hotel Act and to licensing, and the rules of a particular building can restrict or prohibit it. We do not go into the details here, because they depend on the building, the location and the law as it stands when you buy, and a Thai lawyer should check them. The rule is simple: if your numbers rely on short-term letting, confirm that it is lawful in that specific building before you send money, not after.

Questions to ask about any yield figure

Whether the number comes from a developer, a listing, a friend who already bought, or from us, the questions are the same:

• Gross or net? If net, which costs were deducted and which were not?
• Divided by what: the contract price, or everything you put in, including taxes, furniture and transfers?
• What occupancy was assumed, and on what basis?
• Is this a real unit with a letting history, or a forecast for a building that does not exist yet?
• In which currency, and as of which date?
• Who is giving the figure, and what do they gain if you buy?

Then run a cautious scenario yourself: fewer let months than you were offered, the full management fee, a fixed line for repairs, and a less favourable exchange rate than today’s. If the purchase still works for you on those numbers, that is a reasonable starting point. If it only works when everything goes to plan, it is worth stopping to think again.

Rental guarantees: read the contract, not the brochure

Some developers offer a rental guarantee: a promise to pay the owner a fixed amount, usually a percentage of the price, for a set period, provided the unit joins a rental programme run by the developer or a related company. It sounds like an answer to every question above. But a guarantee is worth exactly as much as the company giving it and the words in the contract.

Points to take to your lawyer:

• Who exactly guarantees: the developer, a separate management company, or a company set up for this project? Which of them has assets, if you ever need to claim?
• Is the guarantee secured, for example by a bank guarantee or escrow, or is it only a signature?
• What amount is the percentage calculated on, and is it paid before or after the common fee, insurance and tax?
• When does it start, at handover or later, when does it end, and what happens the day after?
• Can you use the unit yourself, and in which periods?
• What happens if the programme is closed, the developer changes hands, or you want to sell during the guarantee period?

One more question is for yourself: is the price of a unit with a guarantee comparable with similar units without one? If it is higher, part of the “guaranteed” return may be money you paid up front. The contract should be reviewed by a Thai lawyer who acts for you, not for the developer. Checking the developer itself, from track record to completed projects to legal standing, is covered in our guide to developer due diligence.

Yield is only half the return

The other half is the exit: how long a sale may take, who the buyers are, and what taxes and costs fall on you as the seller. That is the subject of our guide to resale and exit. Whether to buy off-plan or a finished unit with a letting history you can examine is discussed in off-plan or ready.

How ROMA ThaiProperty helps

We walk you through every line of the calculation, help you obtain from the developer or management company the data behind the figure you were shown, and help you put together the questions for your lawyer on short-term letting and on any rental guarantee. When we give an estimate, it is labelled as an agency estimate, with its source and date.

What we do not do: promise a yield, give investment or tax advice, or replace your lawyer in Thailand and your tax adviser at home.
