Thailand Rental Yield After Vacancy Costs: 2026 Reality Check

Advertised rental yields in Thailand typically run between 8% and 10% gross. Once you subtract vacancy, management fees, platform commissions, maintenance, and statutory costs, the realistic net figure for most foreign-owned condominiums lands between 3% and 5.5% per year - and sometimes lower. That gap is what this guide exists to explain.

This is not a pessimistic view. Some well-located, professionally managed units do reach 6% net. But the gap between the sales-deck number and the bank-account number is wide enough that you should build your investment case on the net figure, not the gross one.

Quick answer

• Advertised gross yield in popular Thai resort markets: typically 7%-10%, as of 2026 market estimates
• Realistic net yield after all costs: 3%-5.5% for short-term lets; 3.5%-5% for long-term lets, based on indicative operator data
• Vacancy drag: 20%-40% of nights empty is normal in Phuket and Koh Samui outside high season (roughly November to April)
• Management and OTA fees together typically consume 30%-45% of gross short-term rental revenue
• Guaranteed-rental programs usually fix your return at 5%-7% gross for 3-5 years - which can be lower than what a well-run unit earns, while the developer keeps the upside
• Legal constraint: daily short-term lets in a standard residential condominium building may breach the Hotel Act B.E. 2547; always verify the building's hotel licence before assuming short-stay income

Options and scenarios

Scenario 1: Short-term letting in a licensed resort condominium, Phuket

Consider a unit purchased at THB 5,000,000 (roughly USD 140,000 at 2026 indicative exchange rates) in a Kamala or Surin-area building that holds a valid hotel operator licence under the Hotel Act.

Gross potential at 100% occupancy at an average nightly rate of THB 3,000: THB 1,095,000 per year, implying a 21.9% gross yield - a figure developers do use in presentations.

Now apply real-world occupancy. High season (November-April) might reach 75%-85% occupancy. Low season (May-October) often falls to 25%-40%. A blended annual occupancy of 55%-60% is a realistic starting point for a well-marketed Phuket unit, per market estimates as of 2026.

Gross rental income at 57% occupancy: THB 624,150

Subtract the costs:

• OTA platform commission (Airbnb, Booking.com): 15%-18% of collected revenue = approx. THB 100,000
• Property management fee (operator takes 20%-30% of net revenue after OTA): approx. THB 130,000
• Common-area fees ('CAM charges', the monthly fee all owners pay to the juristic person - the legally registered management body of the building): THB 40/sqm/month on a 45 sqm unit = THB 21,600/year
• Sinking fund top-up (a one-time capital reserve paid at purchase, but often supplemented by annual levies in older buildings): allow THB 10,000/year
• Utilities not covered by guest rates: THB 15,000/year indicative
• Repairs, cleaning supplies, linen replacement: THB 20,000/year indicative
• Insurance: THB 8,000/year indicative
• TAX - rental income from Thai property is subject to Thai personal income tax or withholding tax; foreign owners often face a flat withholding arrangement; allow 5% of gross = THB 31,207

Total costs: approx. THB 335,807

Net income: THB 624,150 - THB 335,807 = approx. THB 288,343

Net yield: THB 288,343 / THB 5,000,000 = 5.8%

This is a relatively optimistic scenario. A lower-traffic location, a less active management company, or higher repair costs push this toward 4%-4.5%.

Scenario 2: Long-term monthly letting, Chiang Mai or Bangkok suburb

A THB 4,000,000 one-bedroom unit in an outer Bangkok district or a mid-range Chiang Mai development rents long-term at THB 15,000-18,000 per month.

Gross annual income at THB 16,500/month: THB 198,000

Gross yield: 4.95%

Subtract:

• Management fee (agent fee of one month's rent per new tenant, amortized over a 12-month lease): THB 16,500/year
• Vacancy between tenants (typically 1-2 months per tenant turnover): THB 16,500-33,000/year; use THB 24,750 (1.5 months)
• Common-area fees: THB 35/sqm/month on a 40 sqm unit = THB 16,800/year
• Repairs and repainting between tenants: THB 15,000/year averaged
• Sinking fund and insurance: THB 10,000/year
• Tax: allow 5% of gross = THB 9,900

Total costs: approx. THB 92,950

Net income: THB 198,000 - THB 92,950 = THB 105,050

Net yield: THB 105,050 / THB 4,000,000 = 2.6%

Long-term yields in secondary markets are genuinely modest. The capital-gain story and the lifestyle use case matter more in these locations.

Scenario 3: Guaranteed-rental program from a developer

Many Phuket and Koh Samui developers offer a guaranteed return - commonly 5%, 6%, or 7% gross for a fixed period, typically 3 to 5 years. At first glance this looks predictable. Here is what the guarantee structure actually involves:

• The guarantee is paid on the purchase price, not on market rental income. If the building underperforms, the developer subsidizes from project reserves or future sales revenue.
• You typically assign your unit to a rental pool managed by the developer or a linked operator. You cannot choose your own tenant or platform.
• Your own usage is restricted - commonly 30 days per year, sometimes only in low season.
• After the guarantee period ends, the return reverts to actual market performance, which may be lower than the guaranteed rate if the developer inflated the purchase price to fund the guarantee.
• FET (Foreign Exchange Transaction) certificate requirements still apply: foreign funds used to buy must be remitted in a foreign currency and documented at the Thai bank to allow legal repatriation of sale proceeds later. The guaranteed income does not change this rule.

A 6% guaranteed gross yield on a THB 5,000,000 unit = THB 300,000/year. After Thai withholding tax and your own sinking-fund contributions, the net is closer to 4.5%-5% - and you have surrendered control of the asset.

Hotel licensing: the daily rental legal boundary

This is the most frequently misunderstood cost and risk in Thai resort property. Under the Hotel Act B.E. 2547 (2004), renting a residential unit for stays of fewer than 30 days to a paying guest requires the building to hold a hotel operator licence. The licence is held by the juristic person (the building's management body), not by individual unit owners.

If the building does not have this licence:

• Renting your unit on Airbnb or Booking.com for nightly stays is a legal violation, not merely a grey area
• Fines apply to the building operator and potentially to individual unit owners
• Enforcement has increased in Phuket since 2023, per publicly reported municipal actions
• Your management company may quietly continue to list the unit anyway, transferring legal risk to you

Before purchasing any unit you plan to rent short-term, obtain written confirmation from the juristic person that the building holds the required hotel licence. If the confirmation is not in writing, treat the short-term income as uncertain.

Koh Samui occupancy patterns

Koh Samui follows a similar seasonal pattern to Phuket but with more pronounced low-season troughs. Monsoon (roughly May to October, with a secondary wet period in November on the east coast) can drop occupancy to 15%-30% in some sub-locations. High-season peaks reach 80%-90% in December and January. Annual blended occupancy for a mid-market villa-style condo: 45%-55%, per market estimates as of 2026. At those occupancy levels, the yield math tightens considerably relative to Phuket.

Risks and mistakes

Accepting gross yield without asking for the net. Every sales presentation in Thailand leads with gross yield. It is a legally unregulated marketing number. Always ask for audited net figures from comparable units in the same building. If the operator cannot provide them, treat the gross number as aspirational.

Ignoring the hotel licence question. Many buyers discover after purchase that their building cannot legally host short stays. At that point their only legal option is monthly or longer leases, which typically produce 40%-60% lower income than the short-stay projections.

Underestimating OTA dependence. A unit earning 8% gross on paper may rely on consistent Airbnb top-20 placement. Algorithm changes, negative reviews, or new supply in the building can drop occupancy materially within one season.

Misjudging guaranteed-rental programs. A 7% guarantee sounds superior to a 5% market net. But if the developer priced the unit 15%-20% above comparable free-market units to fund that guarantee, you paid for your own return - and face a mark-to-market loss if you sell after the guarantee period.

Overlooking common-area fees and sinking fund increases. Thai condominium law (the Condominium Act B.E. 2522 and its amendments) requires buildings to maintain a sinking fund - a capital reserve for major repairs. Older buildings often impose special levies when the fund is depleted. These are not optional and directly reduce your net yield.

Assuming exchange-rate stability. Foreign buyers purchasing in Thai baht face exchange-rate risk both on yield and on capital. A 10% baht depreciation against your home currency reduces your effective yield proportionally.

Forgetting repatriation documentation. When you sell, you can only legally repatriate sale proceeds equal to the foreign funds originally remitted. The FET (Foreign Exchange Transaction) certificate - issued by a Thai commercial bank at the time of your original remittance - is the proof. Losing it complicates or delays repatriation of proceeds.

Using informal management with no contract. Some buyers hand their unit to a local contact who manages rentals informally. Without a written management agreement, you have limited legal recourse if funds are misappropriated or the unit is damaged.

FAQ

What is a realistic net rental yield in Thailand in 2026?

For a well-located, properly licensed short-term rental condominium in Phuket, a realistic net yield in 2026 is 4%-5.8% after vacancy, management fees, OTA commissions, maintenance, and tax. Long-term lets in Bangkok or Chiang Mai typically net 2.5%-4%. Guaranteed-rental programs usually deliver 4%-5.5% net after tax and sinking-fund contributions.

How do OTA commissions affect my yield?

Online travel agency platforms (Airbnb, Booking.com, Agoda) charge the host between 12% and 20% of the booking value. If you also use a local property manager, that manager typically takes a further 20%-30% of the revenue that remains after the platform fee. Combined, these two layers can consume 30%-45% of your gross short-term rental income.

Can I legally rent my Thai condo on Airbnb for nightly stays?

Only if the building's juristic person (the legally registered management body) holds a hotel operator licence under the Hotel Act B.E. 2547. Many residential condominiums in Thailand do not hold this licence. Renting without it is a legal violation. Always obtain written confirmation of the licence before purchase.

Is a guaranteed-rental program a safe investment?

It depends on what you are comparing it to. A guarantee eliminates short-term income volatility, which has value. However, the return is usually capped, you lose personal-use flexibility, and the purchase price may have been elevated to fund the guarantee. If the developer's finances weaken during the guarantee period, payment continuity depends on the developer's solvency. Read the full contract, verify who stands behind the guarantee, and obtain independent legal advice before signing.

What is the difference between gross yield and net yield in Thai property?

Gross yield divides annual rent by purchase price, ignoring all costs. Net yield subtracts all operating costs - management fees, OTA commissions, vacancy, common-area fees, sinking-fund contributions, repairs, insurance, and tax - before dividing by purchase price. In Thai resort property, the gap between gross and net is typically 3 to 5 percentage points.

What is a sinking fund and how does it affect my yield?

A sinking fund is a mandatory capital reserve held by the building's juristic person, used to pay for major structural repairs, lift replacement, and similar large expenses. Under Thai condominium law, buyers pay an initial sinking-fund contribution at purchase. Some buildings also collect annual contributions or levy special assessments when the fund runs low. These costs reduce your net annual return and are non-negotiable.

How much does vacancy cost me per year in a resort market?

In Phuket, a realistic blended annual vacancy rate for a mid-market condominium is 35%-45% of nights, using 2026 market estimates. On a unit with a theoretical 100% revenue of THB 1,095,000, that vacancy alone removes THB 380,000-490,000 from your income before any other costs. In Koh Samui, vacancy can be higher due to more pronounced monsoon troughs.

Do I need an FET certificate to repatriate my rental income?

The FET (Foreign Exchange Transaction) certificate is primarily needed to repatriate sale proceeds when you sell the property. For annual rental income, your Thai bank will typically issue a remittance record for each transfer abroad. Keep all remittance documentation organized from day one. A specialist Thai accountant or lawyer can advise on the most tax-efficient method for your specific nationality and residency situation.

How do I compare net yields across different Thai markets?

Use a consistent formula: take the actual (or conservatively estimated) rental income at realistic occupancy, subtract management fees, OTA commissions, common-area fees, sinking-fund levies, repairs, insurance, and income tax, then divide by your all-in purchase cost (unit price plus transfer tax, legal fees, and furnishing). This all-in cost basis gives a more honest return figure than using the purchase price alone.

What is the minimum I should budget for maintenance and repairs?

For a furnished short-term rental unit in Thailand, budget at minimum 1%-1.5% of the unit purchase price per year for maintenance, furniture replacement, and repairs. Tropical conditions accelerate wear on air conditioning, appliances, and soft furnishings. Underfunding this reserve leads to declining guest ratings, which reduces future occupancy and income.
