Thai Property Rental Yield Reality Check 2026: Net vs Gross

Realistic net rental yields on Thai residential property typically land between 3% and 6% per year once every operating cost is counted. Sales decks routinely show gross figures of 7% to 10%, sometimes higher. The gap between those two numbers is the single most important thing you need to understand before committing any capital.

This guide walks through the full cost chain, explains the legal limits on short-term rentals, and compares the main letting strategies honestly, so you can judge any deal on a like-for-like basis.

Quick answer

• Advertised gross yield: typically 7% to 10% in developer marketing, as of 2026
• Realistic net yield after all costs: typically 3% to 6% for well-located condominiums; lower for underperforming units
• Short-term (daily/weekly) letting: higher gross income potential but hotel licensing rules create legal risk in most buildings, and OTA commissions plus vacancy cut returns sharply
• Long-term (monthly) letting: lower gross income but predictable costs, no licensing risk, and lower vacancy
• Guaranteed-rental programs: headline figures of 6% to 8% gross are common, but the guarantee is funded from your own purchase premium and expires after 2 to 5 years
• Key cost items that sales decks omit: management fees, common-area fees, sinking-fund contributions, OTA commissions, repairs, income tax, and vacancy periods

Options and scenarios

Option 1: Short-term letting (daily or weekly rental)

Short-term letting targets tourists and generates the highest nightly rates. On Phuket, market estimates for a one-bedroom condominium in a well-run building show average daily rates of 2,000 to 4,500 THB, as of 2026. On Koh Samui, rates are broadly similar but peak seasons are shorter.

The income looks attractive until you apply the real numbers:

• OTA commissions (platforms like Airbnb or Booking.com): 15% to 20% of booking revenue
• Property management fee for short-term operations: 20% to 30% of gross rental income
• High season on Phuket: roughly November to April (6 months). Occupancy in a well-managed unit can reach 70% to 85% during high season.
• Low season on Phuket and Koh Samui: May to October. Occupancy commonly drops to 20% to 40%. Koh Samui's low season can be more severe due to Gulf-side weather patterns.
• Annual blended occupancy for a realistic unit: 50% to 65%, not the 80% figure sometimes shown in projections
• Hotel licensing: Thailand's Hotel Act requires a hotel license for any building offering paid accommodation for periods shorter than 30 days. Most standard condominiums do not hold this license. Operating daily rentals in an unlicensed building exposes the owner and the juristic person (the condominium's legal management body) to fines and potential closure orders. As of 2026, enforcement has been inconsistent but has intensified in popular tourist areas.

A realistic short-term-yield calculation for a 5,000,000 THB one-bedroom unit on Phuket might look like this:

• Gross annual rental income at 55% blended occupancy: approximately 420,000 THB
• Gross yield: 8.4%
• Less OTA commission (18%): -75,600 THB
• Less property management (25% of net booking revenue): -86,100 THB
• Less common-area fees and sinking-fund contributions (per market estimates, 50 to 80 THB per sq m per month for a 50 sq m unit): -36,000 THB
• Less repairs and maintenance (1% of purchase price per year is a standard rule of thumb): -50,000 THB
• Less Thai personal income tax on rental income (progressive rates; assume 15% effective rate for a non-resident with no deductions): -63,000 THB
• Net yield: approximately 2.2%

This is an indicative scenario, not a guaranteed outcome. Units in premium, well-managed buildings with a hotel license can do better. Units in buildings with weak management or in oversupplied areas will do worse.

Option 2: Long-term letting (monthly contracts)

Long-term letting means renting to a tenant for one year or more, or at minimum for 30-day periods. This avoids hotel licensing risk entirely. Management costs are lower. Vacancy between tenancies typically runs one to two months per year.

For the same 5,000,000 THB unit on Phuket or in central Bangkok:

• Monthly rent for a furnished one-bedroom in a well-located building: 18,000 to 30,000 THB (indicative range, as of 2026)
• Gross annual income at 25,000 THB per month with one month vacancy: 275,000 THB
• Gross yield: 5.5%
• Less property management (8% to 12% of rent for a managed let): -27,500 THB
• Less common-area fees and sinking fund: -36,000 THB
• Less repairs (0.5% of purchase price for long-term tenants who cause less wear): -25,000 THB
• Less Thai income tax (effective rate approximately 10% after standard deductions available to landlords): -21,250 THB
• Net yield: approximately 3.8%

This is more predictable and legally clean. It is also the realistic baseline for most foreign-owned condominiums outside major tourist zones.

Option 3: Guaranteed-rental program

Many developers, particularly in Phuket, Pattaya, and Koh Samui, offer guaranteed-rental programs at purchase. The developer or an affiliated operator promises a fixed return, commonly 6% to 8% of the purchase price per year, for a period of two to five years.

What the program actually involves:

• The premium is baked into the purchase price. Units in guaranteed-rental programs typically sell for 15% to 25% more than comparable units on the open resale market, per market estimates. The guarantee is, in effect, a partial return of your own capital.
• You surrender control. During the guarantee period, you usually cannot use the unit yourself, or are limited to a fixed number of owner-use nights per year (commonly 14 to 30 nights).
• After the guarantee expires, the unit is managed as a standard short-term rental. If the underlying demand is weak, the real yield may fall well below the guaranteed rate.
• Developer credit risk. The guarantee is only as strong as the developer's financial position. If the developer fails, the guarantee is unsecured.
• Resale impact. Units in program buildings can be harder to sell to buyers who are not interested in the program, reducing your exit options.

Guaranteed-rental programs are not inherently bad, but you need to model the post-guarantee yield carefully and compare the all-in purchase price to the open-market value of similar units.

Risks and mistakes

Accepting gross yield without asking for the cost breakdown

A gross yield figure tells you only one thing: annual rent divided by purchase price. It ignores every operating cost. Always ask for the full income and expenditure statement, not just the top-line number.

Underestimating vacancy in the low season

Phuket and Koh Samui are seasonal markets. Short-term rental income from November to April can be two to four times the income from May to October, per market estimates. A projection based on high-season occupancy applied to 12 months is misleading. Ask to see month-by-month occupancy data for the building, not just a blended annual figure.

Ignoring common-area fees and sinking-fund contributions

Every condominium unit in Thailand is subject to common-area fees (also called maintenance fees) paid to the juristic person. These cover shared facilities - lifts, pool, security, landscaping. A sinking fund is a separate reserve for major capital repairs. Combined, these costs commonly run 50 to 120 THB per square metre per month, as of 2026, depending on the building's facilities. For a 60 sq m unit, that is 36,000 to 86,400 THB per year before a single tenant has been found.

Missing the hotel-licensing constraint

The Hotel Act (Thailand's primary legislation governing paid accommodation) requires a license for any premises offering short stays. Most condominium buildings do not hold this license. The building's juristic person may actively prohibit short-term lets to protect the building's status. Before buying with the intent to short-let, confirm in writing that the building is licensed and that the juristic person permits daily rentals.

Overestimating resale value at exit

Yield is only part of total return. If you buy at a premium price in an oversupplied project and cannot resell at a similar or higher price, a 5% annual yield may not compensate for a 15% capital loss at exit. In Thailand, foreign buyers are limited to freehold ownership in the foreign quota of a condominium building (up to 49% of total sellable area, under the Condominium Act). Demand for resale units in the foreign quota varies significantly by location and building quality.

Forgetting Thai income tax

Rental income earned in Thailand is subject to Thai personal income tax, even for non-residents whose income source is in Thailand. The progressive rates start at 5% and reach 35% at higher bands. Standard deductions are available for rental income (a flat 30% deduction is allowed for residential property under Thai Revenue Department rules, as of 2026, but confirm current rules with a qualified tax adviser). Ignoring this cost inflates your net yield estimate.

Relying on a developer's rental management arm

Many developers operate or recommend a property management company. This is not inherently a conflict of interest, but it means the manager has an incentive to report numbers that keep you in the program. Request audited occupancy and revenue statements, and compare them against independent market data where possible.

FAQ

What is a realistic net rental yield for a condominium in Phuket in 2026?

A realistic net yield for a well-located, well-managed condominium in Phuket is in the range of 3% to 5% per year, as of 2026, after management fees, common-area costs, repairs, vacancy, and tax. Short-term rentals in licensed buildings at prime locations can occasionally reach 5% to 6% net, but this requires active management and strong occupancy.

How does gross yield differ from net yield for Thai property?

Gross yield is annual rent divided by purchase price, before any costs. Net yield subtracts all operating costs: management fees, platform commissions, common-area fees, sinking-fund contributions, repairs, insurance, and income tax. In Thailand, the gap between gross and net yield is typically 3 to 5 percentage points, meaning a 8% gross yield commonly becomes a 3% to 5% net yield.

Can I legally rent my Thai condominium to tourists on a nightly basis?

Legally, daily rentals require a hotel license under Thailand's Hotel Act. Most condominium buildings do not have this license. Operating short-term rentals in an unlicensed building creates legal risk for the owner and the building's juristic person. Before buying with short-term letting as your strategy, verify in writing that the building holds the relevant license and that the juristic person's regulations permit daily letting.

What are sinking-fund contributions and how do they affect yield?

A sinking fund is a reserve fund held by the condominium's juristic person for major future repairs - roof replacement, lift overhauls, facade maintenance. You pay an initial sinking-fund contribution at purchase (commonly 500 to 700 THB per square metre at the time of transfer in 2026, but rates vary by project). Ongoing top-up contributions may be levied by the juristic person over time. These costs reduce your net rental income and must be factored into any yield calculation.

What is a guaranteed-rental program and what are the risks?

A guaranteed-rental program is an arrangement where the developer or an operator promises a fixed annual return, typically 6% to 8% of the purchase price, for a set period of 2 to 5 years. The main risks are: the guarantee is often priced into a higher purchase cost, the guarantee expires and post-guarantee yields may be lower, you surrender control of the unit during the program period, and the guarantee depends on the developer's continued financial health.

Is rental income from a Thai property taxed for foreign owners?

Yes. Rental income from Thai property is a Thai-source income and is subject to Thai personal income tax even for non-resident foreigners. A standard deduction of 30% of gross rental income is allowed for residential property under current Revenue Department rules, as of 2026. The remaining taxable income is subject to progressive rates. You should consult a Thai-qualified tax adviser for your specific situation.

How does high season versus low season affect rental income on Phuket and Koh Samui?

Phuket's high season runs roughly from November to April, driven by dry-weather tourism from Europe and China. Low season (May to October) sees significantly lower demand. On Koh Samui, the Gulf of Thailand weather pattern means the peak period is different, roughly February to August, with the low season from September to January often more severe. Annual blended occupancy for a short-term rental unit on either island commonly falls in the 50% to 65% range, per market estimates, not the 75% to 80% sometimes shown in developer projections.

What is a FET and why does it matter for buying Thai property?

A Foreign Exchange Transaction (FET) form is a document issued by a Thai bank when you wire foreign currency into Thailand to purchase property. As a foreign buyer of a condominium in the foreign quota, you must prove that the purchase funds came from abroad in foreign currency. Without a properly recorded FET, you may be unable to repatriate the sale proceeds when you sell. Always ensure the receiving Thai bank issues an FET for each inward remittance and keep the originals.

How do OTA commissions affect short-term rental yield?

Online travel agency platforms charge the property owner or manager between 15% and 20% of the booking value per reservation, as of 2026. On a unit generating 400,000 THB in gross booking revenue, the OTA cost alone is 60,000 to 80,000 THB per year. This is a direct deduction from gross income and must appear in any honest yield calculation.

What is the foreign quota in Thai condominiums?

Under Thailand's Condominium Act, foreigners may own freehold units in a condominium building up to a maximum of 49% of the total sellable floor area of that building. This is the 'foreign quota'. Units sold within the foreign quota can be owned outright by a non-Thai national. When you buy in the foreign quota, your ownership title is a chanote (formal title deed) or a similar condominium title. If the foreign quota in a building is already full, you cannot buy a freehold unit there as a foreigner.
