Thailand Property Prices 2026: Phuket vs Koh Samui Investment Guide

How to Read the Data (For a Fair Comparison)

Phuket and Koh Samui represent two completely different resort real estate markets: Phuket is a large market with a broad range of condominiums and villas, while Samui is more of a "villa island" with smaller-scale projects and different seasonality patterns. Therefore, in this article we compare:

price per sqm (condominiums vs landed property/villas),
location differences (strongest micro-markets),
primary vs secondary market (new development premium),
growth drivers in 2026 (demand, supply, infrastructure, premium segment),
risks that genuinely impact prices and liquidity.

THB → USD Reference (For Clear Price Comparisons)

For conversions, we use approximately 1 THB ≈ 0.029 USD (reference rate for December 30, 2025).
This means:

100,000 THB/sqm ≈ 2,900 USD/sqm
150,000 THB/sqm ≈ 4,350 USD/sqm
200,000 THB/sqm ≈ 5,800 USD/sqm

Phuket 2026: Prices, Segments and Regional Differences

1) Phuket – Benchmark Price Levels

The most reliable and comparable price indicators for Phuket based on market data:

Median condominium prices: 144,000 THB/sqm (≈ 4,176 USD/sqm)
Median villa / landed property prices: 70,000 THB/sqm (≈ 2,030 USD/sqm)

Important detail: In Phuket, the branded residences segment (properties with hotel brand/operator) is increasingly significant, commanding a premium and often substantially outperforming standard projects.

Branded condos: average 181,000 THB/sqm (≈ 5,249 USD/sqm) – approximately 28% premium vs non-branded
Non-branded condos: approximately 141,000 THB/sqm (≈ 4,089 USD/sqm)
Branded landed (villas/landed): up to approximately 162,000 THB/sqm (≈ 4,698 USD/sqm) vs 73,000 THB/sqm (≈ 2,117 USD/sqm) for non-branded landed

2) Phuket – Micro-Markets (Where Prices Peak and Why)

Market reports show clear differences between zones (typical medians/levels by location):

Cherngtalay (Laguna/Bang Tao area): highest price levels; reports indicate extremely high price ceilings for 1-bedroom units in this zone
Rawai: strong lifestyle demand + longer stays, but different tenant profiles compared to Bang Tao
Karon: lower price levels compared to top west coast locations, more traditional tourist demand

In Phuket, the west coast premium and "ecosystem" are increasingly evident: beaches + lifestyle + infrastructure + retail. Bangkok Post has documented significant price differences between off-plan and resale in 2024/2025 (high primary market premium).

3) Primary vs Secondary Market in Phuket (New Development Premium)

This will be a crucial factor in 2026, as resale competition from older projects intensifies:

Non-branded primary (new development): approximately 139,000 THB/sqm (≈ 4,031 USD/sqm)
Non-branded secondary (resale): approximately 100,000 THB/sqm (≈ 2,900 USD/sqm)
representing approximately 39% premium for new development vs resale on average.

This makes sense: new projects offer modern layouts, higher standards, and better facilities, but in 2026 (depending on supply levels), the secondary market could become an increasingly competitive pricing alternative.

4) "Market" Prices in Practice (Ranges)

CBRE's market guide for Phuket indicated that top condominiums in Phuket range from 100,000–180,000 THB/sqm (≈ 2,900–5,220 USD/sqm) depending on quality and location.
Additionally, local media reported that prime properties (Bang Tao/Laguna) can achieve higher prices in the best projects.

Koh Samui 2026: Prices, Segments and Regional Differences

1) Koh Samui – Core Price Indicators

From the C9 Hotelworks report for Samui (June 2025), we have very clear "market medians":

Median condominium prices: 88,500 THB/sqm (≈ 2,567 USD/sqm)
Median landed property prices (villas/landed): 60,600 THB/sqm (≈ 1,757 USD/sqm)

Importantly, Samui has very clear "basket" medians for typical configurations:

1-bedroom condo (40–70 sqm): median 3.5 million THB (≈ 101,500 USD)
2-bedroom condo (80–110 sqm): median 7.2 million THB (≈ 208,800 USD)
3-bedroom villa (250–350 sqm): median 14.9 million THB (≈ 432,100 USD)

2) Samui – Demand Concentration and "Prime Areas"

The report indicates that supply and market value are concentrated in sub-markets (north and east), particularly Bo Phut, Maret, Mae Nam (collectively representing a significant share of market value).

3) Samui and Seasonality: Impact on Prices and Strategy

C9 demonstrates that Samui is positioned as a more "affluent" resort, and the villa rental market is seasonal (peak vs off-season lows) – this affects how investors calculate returns and how properties are valued for rental income.

Phuket vs Koh Samui: 2026 Price Comparison

Reference Levels (baseline, from 2025 data – most useful for 2026 planning)

Phuket condo (median): 144,000 THB/sqm ≈ 4,176 USD/sqm
Samui condo (median): 88,500 THB/sqm ≈ 2,567 USD/sqm

The difference is substantial: Phuket is significantly more expensive in the condominium segment, and additionally, the branded segment in Phuket can drive up prices across entire micro-markets.

What Drives Price Growth in 2026 (And Where Growth Will Be Fastest)

1) Phuket – 2026 Scenario: Selectivity, Premium and Branded

Reports and market commentary suggest that Phuket is entering 2026 more "selectively": strong projects in good locations are maintaining prices, while weaker ones (poor location/product) must compete on price, especially given growing secondary market competition.

Additionally, Phuket has a product "upgrade" trend: branded residences are growing in market share and creating a quality premium, which typically stabilizes prices even with greater supply.

In practice, in Phuket 2026, success typically comes from:

west coast locations and zones with complete "ecosystem"
premium products / well-designed for 1–12 month stays (not just tourist weekends)
branded / managed (where operators genuinely deliver standards)

2) Samui – 2026 Scenario: Limited Scale + Villa Lifestyle

Samui is smaller, more boutique, and more sensitive to specific prime zones. In 2026, growth may occur in:

well-located villas (lifestyle demand + longer stays),
properties in Samui's "prime triangle" (in practice: Bophut/Choeng Mon/Chaweng Noi as premium directions – a trend often indicated in industry analyses, but always worth verifying project-by-project).

Table: Phuket vs Samui – Which Market for Which Investor (2026)

2026 Criterion	Phuket	Koh Samui
Greater project selection (condo + villa)	✅	❌
Strongest branded residences segment	✅	❌
More liquid market (higher transaction volume)	✅	❌
"Boutique" villa atmosphere and smaller scale	❌	✅
Lower median condo price per sqm	❌	✅
Easier micro-market comparison with data	✅	❌

Key 2026 Risks (That Actually Impact Prices)

Primary market premium vs secondary market competition – in Phuket, the difference is already quantifiable and substantial, so in 2026, "good product" increasingly wins over simply being "new".
Supply in weaker locations – price pressure is fastest here (promotions, discounts, "free furniture", etc.).
Seasonality and tenant profile – in Samui, seasonality is pronounced, affecting rental strategy and ultimately valuations.

What to Choose in 2026: Phuket or Koh Samui?

Phuket in 2026: More Expensive, But More Stable and "Long-Stay / Year-Round"

Phuket typically has higher entry prices (especially in western, premium locations), but in return you get a market that in recent years has increasingly functioned not only as a tourist destination, but also as a residential hub: longer stays, lifestyle relocations, remote work, and tenant rotation beyond high season.

This is evident in hotel-tourism data: in the Bang Tao / Cherngtalay zone, average length of stay increased to approximately 7.67 nights in 2024 (from 6.72 in 2023), signaling "longer stays" in one of the island's most investment-worthy districts.
Additionally, Phuket has very strong tourist traffic volume and has approached pre-pandemic levels (supporting rental demand and "exit" opportunities in the premium segment).

When Phuket is the better choice (2026):

when you want to combine short-term rentals in season with longer stays off-season (greater chance of "year-round" income),
when you value a larger market with more comparisons (easier selection),
when you're targeting premium locations with complete "ecosystem" (beaches + infrastructure + retail + services).

Koh Samui in 2026: Cheaper Condos, Stronger Seasonality and More "Short-Stay"

Samui is often cheaper in the condominium segment (medians are significantly lower than Phuket), but it's a more boutique market, often more heavily based on villas for vacation rentals and tourist traffic seasonality.

Here we have a very specific indicator from the market report: average length of stay in Samui is approximately 4–5 nights.
This is statistically closer to "classic short-stay" than longer-stay models. Seasonality is also influenced by flight accessibility: tourism analysis indicates that regular international flights to Samui are limited, with direct connections operated mainly by Bangkok Airways (including from Singapore and Hong Kong)

When Samui is the better choice (2026):

when you're targeting villas and a typical vacation rental model,
when you want a "boutique" island with less project competition in certain micro-locations,
when you accept greater seasonality and want to optimize revenue during peak months.

Quick Decision: Which Market Fits Your Investment Style?

2026 Criterion	Phuket	Koh Samui
Higher entry prices, but greater demand stability	✅	❌
Greater opportunity for longer stays (long-stay)	✅	❌
Typical stay profile more "short-stay"	❌	✅
More seasonal market (greater fluctuations)	❌	✅
Greater liquidity and project selection	✅	❌

Summary

Phuket: more expensive, but typically "easier to defend" prices and demand due to larger market scale and growing share of longer stays in top zones.
Koh Samui: often cheaper (especially condos), but more seasonal and more frequently suited to short-stay models; additionally, limited international flight network reinforces the "island" market character.
