In the first half of 2026, the value of unsold residential supply on Phuket reached 193,741 million THB, while condominium transfers in H2 2025 fell 7.9% year-on-year (per Money and Banking Magazine, August 2026). At the same time, one of Thailand's largest listed developers announced plans to deploy an additional 11.65 billion THB on the island by 2028, bringing its total Phuket commitment to 30 billion THB spread across eight condominium and villa projects covering 3,937 units. We monitor this market continuously, and the trend is clear: the scale of incoming supply is reshaping exit conditions for anyone planning a resale.
The core question for any investor is not whether Phuket is growing, but whether a buyer will exist for their unit in three to five years and at what price. Below, we break that question down into its component parts.
Quick answer
- A major listed developer plans to launch nine new condo projects on Phuket between 2026 and 2028 (Cherng Talay, Kathu-Patong, Bang Tao, Surin, Kata, Phuket Town), with a combined value of approximately 11.65 billion THB, per Money and Banking Magazine, August 2026
- New supply in H2 2025 contracted sharply to 50,171 million THB from 105,921 million THB in the same period a year earlier - a temporary slowdown that does not eliminate inventory pressure
- Unsold stock valued at 193,741 million THB means the market must absorb existing inventory before new launches add further units
- In Q1 2026, Phuket ranked third in Thailand by value of condo transfers to foreign buyers: 420 units worth 2,435 million THB (18.1% of the national total)
- Based on our observations, average listing exposure time on the Phuket secondary condo market in the sub-200,000 USD segment runs 8-14 months, with a typical transactional discount of 8-15% off the asking price (as of 2026)
- Branded residences tied to hotel operators (Hilton, Marriott) represent a growing competitive category that secondary-market sellers cannot replicate in terms of managed rental guarantees and brand recognition
Options and scenarios
How large-developer expansion affects Phuket condo resale prices
The mechanism is straightforward to describe, harder to quantify precisely. When a listed developer launches a project in Cherng Talay at an entry price of 110,000-130,000 THB per sqm, supported by a showroom, a guaranteed rental program and interest-free installments during construction, an individual secondary-market seller in the same sub-district competes without any of those tools. Based on our estimates, an investor trying to exit a condo within 2 km of a new branded launch will experience exposure times running 30-50% longer than in locations where fresh supply is not entering directly.
We identify three distinct scenarios based on price segment and holding period:
Scenario A: Freehold condo within the foreign-ownership quota, under 200,000 USD (approximately 7 million THB) This is the most active segment among foreign investors. Buyer depth is relatively widest here, which supports liquidity. The complication arises when a new project offers a comparable product at a similar price point with a 5-7% rental guarantee attached. In our data, transactional discounts in this segment run 8-12% off the listed price, with a typical time to closing of 8-14 months.
Scenario B: Premium condo and branded residences, 300,000-800,000 USD This is where cannibalisation is most pronounced. Buyers in this range have access to new launches carrying Hilton, Marriott or Wyndham branding, which deliver professional management and clear market positioning. An individual seller offering an unbranded condo at this price tier faces exposure times of 12-24 months and discounts of 12-20%. We track listings in Surin and Bang Tao where units completed in 2020-2022 remain unsold.
Scenario C: Villas held in leasehold or through a Thai company structure This is a separate liquidity category. The legal structure (30+30+30-year leasehold or Thai Co. Ltd.) narrows the buyer pool to those comfortable accepting the associated legal risk. Based on our estimates, premium villas above 15 million THB on Phuket carry exposure times of 14-30 months and discounts reaching 15-25%. On Koh Samui, where the market is considerably smaller, these parameters are more demanding still.
Holding-period mathematics: what the real annual return looks like
We model the following baseline: freehold condo on Phuket, purchase price 5 million THB. Net rental income after management costs: 5% per year (250,000 THB). Exit costs include transfer fee (2%), specific business tax or stamp duty (approximately 3.3% if sold within 5 years of acquisition), agent commission (3-5%), and miscellaneous fees (approximately 0.5%).
Three-year horizon (sale before the five-year SBT threshold):
- Cumulative rental income: 750,000 THB
- Transaction exit costs at flat sale price: approximately 440,000 THB (8.8% combined)
- Net result: +310,000 THB, equivalent to +2.1% per year on invested capital
- If the sale requires a 10% discount: result turns negative at -1.6% per year
Five-year horizon (sale after five years, stamp duty of 0.5% instead of SBT at 3.3%):
- Cumulative rental income: 1,250,000 THB
- Exit costs (lower): approximately 300,000 THB (6% combined)
- Net result at flat price: +950,000 THB, equivalent to +3.8% per year
- With a 10% discount: +450,000 THB, equivalent to +1.8% per year
Ten-year horizon:
- Cumulative rental income: 2,500,000 THB
- Exit costs: approximately 300,000 THB
- Net result at flat price: +2,200,000 THB, equivalent to +4.4% per year
- With 15% price appreciation (a realistic outcome for a well-located unit over a decade, based on our estimates): +2,950,000 THB, equivalent to +5.9% per year
The conclusion from this arithmetic is consistent: holding periods under five years are structurally exposed to risk under current supply and cost conditions. Crossing the five-year mark lowers the tax burden materially (SBT replaced by stamp duty) and gives the market time to absorb new supply.
Timing the sale: when the market favors a seller
We track three cyclical factors in our data:
Seasonality: Transaction activity on Phuket peaks in November through March (dry season, tourism high season, buyer site visits). Listing a property in May through September typically extends exposure by 3-5 months on average.
Supply cycle: The 24-36-month gap between a project announcement and completion creates a window during which the secondary market holds a specific advantage - a completed unit generating immediate rental income versus an off-plan purchase still under construction. We monitor handover schedules and observe that 2026-2027 will bring a wave of completions from projects launched in 2023-2024.
Currency: Exchange rate movements between THB and major investor currencies can have a larger impact on the real return than the transactional price discount. In 2025, the Thai baht weakened against several reference currencies, creating an additional headwind on capital repatriation. We verify on the ground that investors who purchased in 2021-2022 during a period of relative currency weakness now hold a more favorable exchange-rate position.
Off-plan contract assignment before handover
This is a separate exit route we analyze independently. Many Phuket developers formally permit contract assignment, but with meaningful constraints:
- Assignment fee: typically 1-3% of the contract value, charged by the developer
- Some developers require the incoming buyer to complete full KYC and accept the original contract terms in their entirety
- Certain contracts include a resale restriction before construction completion or before a defined installment threshold is reached (often 50-70% of the purchase price paid)
- The assignment market lacks transparency: no central registry exists, and transactions are arranged primarily through brokers or social-platform groups
Based on our observations, off-plan assignment on Phuket in 2026 can deliver a modest positive exit of 2-8% above installments paid, for projects with strong branding and prime locations (Bang Tao, Surin). Projects in less sought-after sub-districts (Kathu, parts of Phuket Town) may require pricing at nominal cost or accepting a minimal loss.

Risks and mistakes
Mistake 1: Benchmarking the purchase price against listed prices rather than closed transactions. We compare asking prices with transactional prices and find that on the Phuket secondary market, the actual closing price runs consistently 8-20% below the listing price depending on segment. Investors who base exit projections on portal listings systematically overstate expected proceeds.
Mistake 2: Underestimating the branded-residence effect. Projects carrying Hilton, Marriott or Moxy branding (three hotels scheduled for handover from Q4 2026 onward, totaling 601 keys, per Money and Banking Magazine) establish a new competitive benchmark that directly targets secondary-market buyers in the premium segment. An investor holding an unbranded condo priced at 15 million THB must assume that at the point of resale they will be competing against a newly delivered branded residence at a similar price point.
Mistake 3: Ignoring specific business tax. Selling a Thai property within five years of acquisition triggers specific business tax at 3.3% of the sale price or appraised value, whichever is higher. After five years, this is replaced by stamp duty at 0.5%. That 2.8-percentage-point difference has a direct and material impact on short-horizon returns.
Mistake 4: No exit strategy at the point of purchase. We observe that the majority of investors do not assess secondary-market liquidity before committing to a purchase. The choice of location, price segment and ownership structure should incorporate an exit scenario from the reservation agreement stage onward.
Mistake 5: Overestimating Koh Samui liquidity. The Koh Samui market is considerably smaller than Phuket. Based on our estimates, condo transaction volume on Samui represents less than 15% of the Phuket total. Exposure times are proportionally longer and the buyer pool is shallower. For investors who prioritize a defined exit horizon, Phuket remains the more liquid of the two markets.
FAQ
How long does it take to sell a condo on the Phuket secondary market in 2026?
Based on our observations, average listing exposure time for a condo in the sub-200,000 USD segment runs 8-14 months as of 2026. In the premium segment (above 300,000 USD), that extends to 12-24 months.
What is the typical discount off asking price when reselling a Phuket condo?
We track closed transactions against listing prices and observe a typical discount of 8-12% in the standard segment and 12-20% in the premium segment. For leasehold villas, the discount can reach 15-25%.
Do branded residences cannibalize the Phuket secondary condo market?
Yes, in the price range above 10 million THB, new hotel-branded projects (Hilton, Marriott and similar) compete directly with secondary-market units. They offer professional management, rental guarantees and brand recognition that an individual seller cannot replicate.
What are the transaction costs when selling property in Thailand?
Combined exit costs run approximately 6-9% of the transaction value. They include transfer fee (2%), specific business tax (3.3% if held under five years) or stamp duty (0.5% after five years), withholding tax (progressive, dependent on value and holding period), and agent commission (3-5%).
Is it profitable to sell a Phuket condo after three years?
At a three-year horizon and assuming the sale price equals the purchase price, the real annual return (factoring in rental income and exit costs) is approximately 2.1%. If the sale requires a 10% discount, the result turns negative. Holding periods under five years carry elevated risk due to the specific business tax rate.
Can off-plan contract assignment work as an exit strategy on Phuket?
Assignment allows an exit before unit handover, but comes with constraints: an assignment fee of 1-3%, minimum installment thresholds, and a low-transparency market. In well-located projects in Bang Tao or Surin, the gain over installments paid typically runs 2-8% in 2026. Projects in less sought-after locations may require pricing at nominal cost.
What is the minimum viable holding period for a Phuket freehold condo?
Based on our analysis, the minimum holding period to achieve a positive net result after accounting for transaction costs and discount risk is five years for a freehold condo in the standard price segment.
How large is the unsold residential supply on Phuket in 2026?
Unsold supply on Phuket was valued at 193,741 million THB at the close of H2 2025, per data cited by Money and Banking Magazine in August 2026. This is a historically elevated level and sustains downward price pressure on the secondary market.
Does Koh Samui offer better resale liquidity than Phuket?
No. Based on our estimates, condo transaction volume on Koh Samui represents less than 15% of Phuket's total. Exposure times are longer and the pool of qualified buyers is smaller. Phuket remains the more liquid market for investors with a defined exit timeline.
How does the THB exchange rate affect Phuket investment returns for foreign buyers?
Currency movements can outweigh the impact of a price discount at exit. Buying during a period of relative THB strength and selling during a period of weakness creates a compounding headwind on repatriated capital. We verify on the ground that entry timing relative to the exchange rate is a factor investors routinely underweight.
Our overall assessment: the expansion of listed developers on Phuket (11.65 billion THB of new supply planned through 2028) is structurally altering exit conditions for individual investors. The data points consistently toward minimum five-year holding periods, a preference for the sub-200,000 USD freehold segment on liquidity grounds, deliberate avoidance of direct competition with branded-residence launches, and the integration of a resale scenario into the purchase decision from day one. We monitor this market continuously and update our data sets quarterly.
