Thailand Rental Yields: What a UK Investor Actually Keeps.

Gross yield is a year's rent divided by the purchase price. A £250,000 (฿11.1m) condo let for £20,000 a year has a gross yield of 8%. It is the figure in every brochure because it is the largest number available.

Net yield takes off everything that sits between the guest's payment and your income:

• Operator's share: in a managed programme, typically the largest single deduction.
• Running costs: common area fees, insurance, utilities in void periods, repairs and furniture replacement.
• Land and Building Tax: on a second-home condo, 0.02% to 0.10% of the appraised value from the first baht.
• Thai tax on the rent, then UK tax on the same profit, with credit for the Thai tax.
• Buying costs: your share of the 2% transfer fee and legal fees, which raise the true cost of the asset.

Ask for a net figure on every project you consider, and ask what it is net of. "Net of management" is not net of tax.

The most quoted number comes from a Bangkok Post report from around 2024, in which CBRE's Phuket head of sales put yields in prime areas above 10%. It is a real quote from a credible firm, and it should be read carefully:

• It is not stated as net. The report does not say the figure is after the operator's share, costs or tax. Treat it as gross.
• It is a prime-area figure. The report ties it to high-demand locations such as Bang Tao and the Laguna area. It is not an island-wide average.
• It comes from the sales side of the market. That does not make it wrong, but it is not an independent index.

Other published claims, often credited to unnamed rental operators, put Phuket averages at about 8% to 10%, again without saying gross or net. Our view: a strong managed unit in a good west-coast location can produce a high gross yield. A plan that depends on 10% net will disappoint.

The rule: letting a property for periods of under 30 days needs a licence under the Hotel Act. A private owner letting a condo to holidaymakers for a week at a time, without a licence, is outside the law.

Condo bylaws: many condominium juristic persons ban stays of under 30 days in their bylaws, whatever the national law says. Those rules bind every owner in the building.

Reform is pending, not passed. Bills to reform short-term letting were in committee in July 2026, and a draft Accommodation Establishment Act was published on 29 September 2026. Neither is enacted. We will update this guide when either becomes law, and we do not price any future relaxation into the numbers we show clients.

What this means in practice:

1. Hotel-licensed programmes run by an operator that holds the licence are the clean route to nightly and weekly lets.
2. Long lets of 30 days or more are open to any owner, subject to the building's rules.
3. Unlicensed nightly letting is a risk to your income and your standing with the building. We don't recommend it and we don't sell on it.

Long lets (30 days or more, usually six to twelve months) suit owners who want simplicity. Rent is lower per night but occupancy is steadier, wear is lower and there is no operator taking a revenue share. Tenants are typically expatriate families, remote workers and long-stay retirees. Your costs are an agent's finding fee, periodic maintenance and the occasional void.

Managed programmes pool the units in a licensed development and let them by the night through the operator's channels. Gross revenue is higher and you do nothing, but the operator takes a large share of revenue, the furniture wears faster, and your personal use is restricted by the programme's rules.

What tips the decision:

• How much you will use it. Heavy personal use in high season undermines a managed programme's best weeks.
• The building's licence. If it has no hotel licence, nightly letting is not a legal option.
• Your tax rate. A higher-rate UK taxpayer keeps less of every extra pound of rent, which narrows the gap between the two models.

High season runs from November to April, when the Andaman coast is dry and calm and European winter demand peaks. The south-west monsoon brings rain and rougher seas from roughly May to October, and nightly rates and occupancy fall with it.

For an owner, the season shows up here:

• Pricing a managed programme: most of the year's revenue is earned in the high-season months, so a programme's annual figure depends heavily on Christmas, New Year and the European half-terms.
• Personal use: owners who block out December and January give away the most valuable weeks of the year.
• Long lets: a twelve-month tenancy smooths the cycle, and green-season demand from long-stay visitors and remote workers is steadier than nightly demand.

The swing is visible in the airport data. C9 Hotelworks' review of 2024 shows Phuket airport arrivals peaking at about 950,000 in December, against about 530,000 in September. Island-wide hotel occupancy averaged 69% across 2024.

Phuket's visitor base is also broad. In 2024 Russia (1.07m) and China (0.99m) led, followed by India (0.48m), Australia (0.28m) and the UK (0.25m, up 37%), on C9's figures. Thailand as a whole received 32.97m international arrivals in 2025, and UK arrivals passed 1m on 17 December 2025. A building whose guests come mostly from one country is exposed to that country's flights and currency. The new Virgin Atlantic non-stop from Heathrow to Phuket, three times a week from 18 October 2026, adds direct UK capacity to the island.

A rental guarantee is a promise by a developer or operator to pay you a fixed percentage of the purchase price each year, usually for the first few years after completion. Read one the way a lender would:

• Who is guaranteeing it? A guarantee is only as good as the company behind it. A single-project company with no other assets can't pay out if the project underperforms.
• Is it gross or net? Check whether common area fees, furniture replacement and tax come out of it or on top of it.
• What happens after it ends? Income usually drops to an actual revenue share when the guarantee expires. Ask for the operator's real trading figures on comparable buildings.
• Is it priced in? A guarantee costs the developer money. If the purchase price is above comparable stock, you may be prepaying your own return.
• Is the payment subject to withholding? Rent paid to a non-resident by a Thai company is subject to 15% withholding tax.

A guarantee can be useful in the first years of a new resort. It is never a reason to buy on its own.

Costs fall into three groups. The exact figures vary building by building, so ask for them in writing before you reserve.

• Revenue share or management fee: in a managed programme, the operator keeps a share of room revenue to cover reception, housekeeping, marketing and booking-channel commissions. It is the biggest number in your cost line.
• Common area fees: a charge per square metre of your unit, paid to the condominium juristic person for the building, pool, gardens and security. These vary widely between developments, so don't rely on an average.
• Owner's costs: insurance, furniture and fittings replacement, deep cleaning and maintenance reserves, and Land and Building Tax.

For long lets, a local agent typically charges a finding fee and, if you want it, a monthly management fee for inspections, repairs and rent collection.

This is an illustration with stated assumptions, not market data or a forecast. Every input below is ours, chosen to show the arithmetic.

Assumptions:

• Purchase price: £250,000 (฿11.1m) at about ฿44.5 to £1
• Buyer's share of the transfer fee: 1% (half the 2% fee), £2,500
• Legal and due diligence: £2,500
• Total cost: £255,000
• Managed programme, gross room revenue: £21,000 a year (8.4% gross on the price)
• Operator's share: 40%, so £8,400
• Owner's share of revenue: £12,600
• Owner's costs: common area fees £1,200, insurance £300, Land and Building Tax about £50, repairs and replacement £600. Total £2,150
• Thai tax: 15% withheld on the owner's share, £1,890, used as the Thai figure for simplicity
• UK tax: the property income rates that apply to UK and overseas rental profits from 6 April 2027 in England, Wales and Northern Ireland (22% basic, 42% higher)

The arithmetic:

1. Owner's share £12,600, less costs of £2,150, gives net operating income of £10,450. That is 4.1% on £255,000.
2. Thai withholding: 15% of £12,600 = £1,890.
3. UK tax on a profit of £10,450 for a higher-rate taxpayer: 42% = £4,389. Credit relief for the £1,890 of Thai tax leaves £2,499 to pay HMRC. Total tax is £4,389.
4. Net after both taxes: £10,450 − £4,389 = £6,061, or 2.4% on total cost.
5. For a basic-rate taxpayer: UK tax at 22% = £2,299, less the £1,890 credit, leaves £409 to pay HMRC. Net after tax is £8,151, or 3.2%.

What the example shows:

• An 8.4% gross yield becomes 2.4% to 3.2% in your pocket on these assumptions.
• The UK rate decides the outcome. Thai tax is credited against UK tax, so the higher of the two rates is what you effectively pay.
• File in Thailand anyway. Thai tax on rent is charged at progressive rates of 0% to 35% after a 30% standard deduction, so the real liability is often below the 15% withheld. Filing recovers the difference. HMRC only credits Thai tax you could not have reclaimed, so while the UK rate is the higher one, filing moves money from the Thai side to the UK side without changing the total.
• The pound moves the result. Rent earned in baht and spent in sterling rises and falls with the exchange rate.

We don't sell a rental programme on its headline number. Before we put one in front of a client, we check:

1. The licence. A hotel licence held by the operator, or a credible plan to obtain one, if nightly letting is part of the case.
2. The operator's track record. Real trading figures from comparable buildings it already runs: occupancy, average nightly rate and owner payouts, not projections.
3. The split and the cost line. Revenue share, common area fees and furniture reserve set out in writing, with nothing left vague.
4. Owner use. Clear rules on how many nights you can use, and which weeks.
5. Exit. Whether you can leave the programme, and on what notice, if you want to let privately or sell.
6. Location. Stock within reach of the west-coast beaches and the airport, where demand holds up outside peak weeks.

Among the developments we sell, Sole Mio Residences in Bang Tao and Verdi Villas Phuket near Layan suit different strategies: the first managed apartments, the second villas for owners who want more personal use. The Thailand desk sends current price lists and rental terms on WhatsApp, and a 30-minute call is usually enough to see whether the numbers suit your tax position.

Rental income in Phuket is a contribution to the return, not the whole return. The case for buying usually rests on a mix: some weeks of personal use, rent for the rest of the year, and capital growth over a longer hold. The Phuket area guide shows where each strategy fits.
