By the way, we keep updated a blog article detailing the property taxes and fees to factor in the total buying cost in Thailand.
Meanwhile, here is a detailed table of the additional expenses you may have to pay when buying a new property in Koh Samui
| Extra cost | Type | Estimated cost range |
|---|---|---|
| Transfer fee | Government fee | Usually up to 2% of the assessed value. In practice, this is often negotiated between buyer and seller. For many Koh Samui purchases, this can mean roughly ฿100,000 to ฿1.6 million, or about $3,000 to $49,000. |
| Specific Business Tax or stamp duty | Tax | This is often a seller-side cost, but it can affect the final negotiation. The usual range is about 0.5% to 3.3% of the assessed or contract value. Buyers should still understand it before agreeing on a final price. |
| Withholding tax | Tax | This is usually seller-side, but it still matters because sellers may include it in the negotiation. The amount depends on the seller type and holding period. It is best checked during legal due diligence. |
| Legal due diligence | Professional fee | A normal legal review in Koh Samui may cost about ฿80,000 to ฿250,000, or about $2,400 to $7,600. This is important because title, access road, zoning, and building checks matter a lot on the island. |
| Agent commission | Transaction cost | The agent commission is often paid by the seller and is commonly around 3%. Even when the buyer does not pay it directly, the commission can still be built into the asking-price behavior. |
| Furniture package | Fit-out | A furniture package can cost about ฿300,000 to ฿3 million, or about $9,000 to $91,000. The final amount depends on the size of the villa, the number of bedrooms, and whether the home is rental-ready. |
| Light renovation | Renovation | Light renovation can cost about ฿8,000 to ฿20,000 per sq m, or about $244 to $609 per sq m. This usually covers paint, small repairs, basic upgrades, and simple refresh work. |
| Heavy renovation | Renovation | Heavy renovation can cost about ฿25,000 to ฿60,000 per sq m, or about $761 to $1,827 per sq m. This can include bathrooms, kitchens, structure, electrical systems, plumbing, and major villa upgrades. |
| Pool, garden, and MEP repairs | Maintenance and renovation | Pool, garden, mechanical, electrical, and plumbing repairs can cost about ฿300,000 to ฿2.5 million, or about $9,000 to $76,000. Older villas in Koh Samui can need this work before they are comfortable to use or rent. |
| Survey, company setup, accounting, and permits | Legal and admin | These costs can be around ฿50,000 to ฿300,000, or about $1,500 to $9,000. They depend on the ownership structure, the land setup, and the level of paperwork needed. |

What sources have we used to write this blog article?
Whether it’s in our blog articles or the market analyses included in our property pack about Koh Samui, we always rely on the strongest methodology we can and we don’t throw out numbers at random.
We also aim to be fully transparent, so below we’ve listed the authoritative sources we used, and explained how we used them and the methods behind our estimates.
| Source and link | Why we trust it | How we used it |
|---|---|---|
| Bank of Thailand residential property price index | It is Thailand’s central bank and publishes the official residential property price index. | We used it to anchor Koh Samui estimates against national and Southern Thailand price trends. We treated it as a price-trend control, not as a direct Koh Samui transaction dataset. |
| Bank of Thailand daily exchange rates | It is the official Thai central-bank source for foreign exchange rates. | We used it to convert Thai baht prices into US dollars. We used about ฿32.846 per US dollar for the June 2026 reference conversion. |
| European Central Bank THB/EUR reference rate | It is the euro area’s official central-bank source for euro reference exchange rates. | We used it to convert Thai baht prices into euros. We used about ฿37.811 per euro for the June 2026 reference conversion. |
| Real Estate Information Center, Government Housing Bank | It is Thailand’s main real estate data center and is backed by the Government Housing Bank. | We used it to understand the broader Thai residential market. We did not use it as a direct Koh Samui price source because public data is not granular enough for the island. |
| C9 Hotelworks Samui Property Market Update | It is a specialized consultancy report focused on Koh Samui real estate and hospitality. | We used it to cross-check the structure of the Koh Samui residential market. We also used it as a sanity check for market value and price-per-sq-m benchmarks. |
| C9 Hotelworks Samui Hotel and Tourism Market Review | It tracks Koh Samui tourism, which is a major driver of villa demand. | We used it to understand why second-home and rental-investment demand stayed resilient. We connected tourism recovery with demand for rental-ready villas. |
| FazWaz Koh Samui listings | It is one of Thailand’s major property portals and has many Koh Samui listings. | We used it to sample live asking prices by property type and location. We adjusted these prices down because asking prices are usually above closed sale prices. |
| Thaiger Property Koh Samui listings | It provides a large Koh Samui listing set using property-market data from FazWaz. | We used it as a second listing-market cross-check. We treated extreme price-per-sq-m figures carefully because mixed listings can distort portal averages. |
| DDProperty Koh Samui listings | It is a major Thai property portal with broad agent coverage. | We used it to verify upper-end Koh Samui residential listings. We did not use it alone because portals can include duplicates and non-standard property types. |
| Samui Property Group Koh Samui Market Report 2026 | It is a local Koh Samui brokerage report with on-the-ground price ranges. | We used it as a local qualitative cross-check. We gave it less weight than official data and large listing aggregators because it is a brokerage source. |
| Thailand Department of Lands | It is the official Thai government body linked to land registration and transfer procedures. | We used it to frame buyer-cost items such as transfer fees and registration-related checks. We used this only for cost structure, not for Koh Samui sale prices. |
| Thailand Revenue Department | It is the official Thai tax authority. | We used it to understand tax items that can affect property transactions. We kept the explanation simple because tax treatment depends on the seller and the transaction structure. |
| Tourism Authority of Thailand Newsroom | It is an official tourism information source for Thailand. | We used it as background for Thailand tourism trends that affect island property demand. We used it only as a demand-side context source. |
