Only around 8-12% of condominium buildings in Phuket hold a hotel licence that permits legal short-term rentals, based on our on-the-ground monitoring as of Q1 2026. For any investor planning guest rotations shorter than 30 days, that figure is the first and most critical barrier to entry. We have tracked this market for several years, and the pattern is consistent: unfamiliarity with the regulatory framework leads to measurable financial losses and legal exposure.
The Thai Hotel Act B.E. 2547 (2004) classifies any rental of less than 30 consecutive days as a hotel operation. Running such an operation without a licence can result in a fine of up to 20,000 THB per incident and a cease-and-desist order. Enforcement has visibly tightened in Phuket since 2023. On Koh Samui, local authorities have been running inspections specifically in Chaweng and Bophut.
Quick answer
- Short-term rental (under 30 days) requires a hotel licence under Hotel Act B.E. 2547; operating without one risks fines of up to 20,000 THB per incident
- Legal short-stay rental is available only in buildings that hold a hotel licence or that are registered as serviced apartments
- External property management companies typically charge 20-30% of gross revenue for short-stay management
- Rental pool models pay the owner 40-50% of pooled gross income
- Guaranteed-return schemes advertise 5-7% of purchase price per year, but purchase prices are commonly inflated by 10-20% to offset that commitment
- The high season (November through March) accounts for 60-70% of annual rental income in Phuket
Options and scenarios
When can a building legally offer nightly rentals?
A hotel licence (ใบอนุญาตโรงแรม) is granted to buildings that meet fire safety, sanitation and registration requirements. In Phuket, our data sets show a cluster of licensed projects in Bang Tao and Layan - these are typically condotels or branded residences. Kamala and Surin have far fewer licensed buildings. On Koh Samui, licences are concentrated around Bophut (near Fisherman's Village) and parts of Chaweng.
Without a hotel licence, the minimum permissible rental period is 30 days. We monitor listings across major OTA platforms and consistently find owners advertising 28-day stays, which technically violates the Hotel Act. In the event of an inspection, both the operator and the property owner face liability.
Model 1: Rental pool
In this structure, the developer or hotel operator manages the entire building. Revenue from all units flows into a shared pool and is distributed proportionally by unit size or category.
- Typical split: 50-60% to the operator, 40-50% to the owner (based on our data from Phuket projects, 2025-2026)
- The owner has no influence over pricing policy, guest selection or distribution channels
- Cleaning, laundry, minor repairs and OTA commissions are generally absorbed within the operator's share
- Personal use is restricted - usually 14 to 60 days per year depending on the contract
Model 2: External property management company
The owner contracts an independent management firm. Comparing operator reports across Phuket and Koh Samui, we see the following cost ranges:
- Management fee: 20-30% of gross revenue for short-stay rentals; 10-15% for monthly rentals
- Cleaning per turnover: 500-1,200 THB depending on unit size
- OTA platform commissions (Airbnb, Booking.com): 3-18% of revenue
- Minor repairs and upkeep: 2,000-5,000 THB per month (based on our estimates for a 40-60 sqm unit)
- The owner retains full control over pricing and the booking calendar
Model 3: Guaranteed return
Developers offer a fixed yield - most commonly 5-7% of the purchase price per year for a period of three to five years. Based on our on-the-ground verification, the hidden cost of this model includes:
- Purchase prices inflated by 10-20% relative to comparable units without a guarantee
- Sinking fund and common area maintenance (CAM) fees borne by the owner: 40-80 THB per sqm per month
- No transparency on actual occupancy - owners receive no operational data
- Developer insolvency risk once the guarantee period expires
Model 4: Self-management from abroad
This is feasible for monthly rentals (which do not require a hotel licence), but in practice it requires a local power of attorney, round-the-clock availability across the UTC+7 time zone and familiarity with the Thai market. Monitoring owner communities, we estimate that self-management from abroad generates an average of 15-25 additional vacancy days per year compared with a professional operator.
Worked example: external operator, Bang Tao, Phuket
Assumptions: 45 sqm unit, purchase price 5,500,000 THB, short-stay rental in a hotel-licensed building.
- Annual gross revenue: 720,000 THB (65% occupancy, ADR 3,000 THB - based on our 2026 estimates)
- Management fee (25%): -180,000 THB
- OTA commissions (average 12%): -86,400 THB
- Cleaning (120 turnovers x 700 THB): -84,000 THB
- Utilities (electricity, water, internet): -36,000 THB
- Minor repairs and maintenance: -30,000 THB
- CAM fee (60 THB/sqm x 12 months): -32,400 THB
- Total costs: 448,800 THB
- Net owner return: approximately 271,200 THB
- Net yield on purchase price: approximately 4.9%
For comparison: the same unit in a rental pool with a 45/55 owner-operator split would deliver approximately 324,000 THB gross to the owner, but after CAM fees and withholding tax the net figure falls to a comparable 270,000-290,000 THB.

Risks and mistakes
Operating short-stay rentals without a hotel licence is the most common error among foreign owners. Based on our observations in Phuket during 2025, local authorities conducted dozens of inspections in Rawai and Kata. Consequences extend beyond fines: a property entered into the violations register faces complications at resale.
Ignoring seasonality produces overstated projections. In Phuket, low-season occupancy (May through October) sits at 30-45%, while the high season (November through March) reaches 75-90%. On Koh Samui the swings are even more pronounced. Chaweng sustains relatively higher year-round occupancy driven by Asian tourist flows, whereas Maenam sees short-stay occupancy drop below 25% in July and August.
OTA commissions are a variable, not a fixed cost. Airbnb charges hosts 3-5% plus a separate guest-side fee; Booking.com charges the host 15-18%. Platform selection alone shifts the annual P&L by several percentage points.
Currency risk (THB to other currencies) is real. Over the 12 months from March 2025 to March 2026, the THB moved within a range that implied a difference of up to 15% in converted returns depending on timing, based on publicly available exchange rate data.
Thai withholding tax on rental income for non-residents is 15% at source. Investors who are tax residents in their home country must also declare this foreign income under the applicable double taxation agreement - the terms of which vary by country and affect how much, if any, of the Thai tax is creditable at home.
FAQ
Can I legally rent out a Phuket apartment on a nightly basis without a hotel licence?
No. The Thai Hotel Act B.E. 2547 classifies any rental under 30 days as a hotel operation requiring a licence. Without one, fines of up to 20,000 THB per incident apply, and the authorities can order the operation to cease.
What is the typical management fee for a Phuket rental operator in 2026?
External operators charge 20-30% of gross revenue for short-stay management. In a rental pool structure, the operator's share rises to 50-60% of pooled revenue.
What net yield should I expect from a rental unit on Koh Samui?
Based on our estimates, net yield after all costs and commissions runs at 4-6% per year for licensed units in Bophut and Chaweng, assuming average annual occupancy of 55-65%.
How does seasonality differ between Phuket and Koh Samui?
Phuket has a clear peak from November to March (occupancy 75-90%) and a trough from May to October (30-45%). Koh Samui has a secondary micro-season in July and August driven by Chinese and Korean visitors, though quieter districts such as Maenam still fall below 25% short-stay occupancy during that window.
Is a guaranteed return of 7% per year a strong offer?
Advertised guaranteed returns of 5-7% appear attractive, but our on-the-ground checks consistently show that the purchase price is inflated by 10-20% relative to comparable units without a guarantee. On a like-for-like basis, the effective yield falls to a range similar to other management models.
What costs does the owner bear beyond the management fee?
The main additional items are: OTA commissions (3-18%), cleaning per turnover (500-1,200 THB), utilities (approximately 3,000 THB per month), CAM fees (40-80 THB per sqm per month) and minor repairs (2,000-5,000 THB per month).
Is self-management from abroad financially worthwhile?
For monthly rentals it is workable, but our data indicate it generates 15-25 additional vacancy days per year compared with a professional operator. A local power of attorney and availability during Thai business hours are both necessary.
Which Phuket districts have the most hotel-licensed buildings?
Our monitoring identifies the highest concentration of licensed condotels and branded residences in Bang Tao and Layan. Kamala, Surin and Nai Harn have significantly fewer options. Rawai and Karon are dominated by long-stay rental inventory.
Do OTA platforms verify hotel licences in Thailand?
As of Q1 2026, OTA platforms do not actively verify hotel licences in Thailand. Legal responsibility rests with the property owner and the operator.
How should I start evaluating a short-stay rental investment in Thailand?
We recommend beginning with a verification of the building's hotel licence status - this is a prerequisite for legal nightly rentals. From there, model at least two management scenarios (external operator vs rental pool) using actual figures for the specific district and unit type. Seasonality and operating costs vary materially between districts, and generic assumptions lead to material forecasting errors.
