Hidden Costs of Buying Property in Thailand
When buying property in Thailand, the headline purchase price is only part of what you’ll actually pay. Transfer fees, specific business tax (3.3%), stamp duty, legal fees, sinking fund, and maintenance deposits add 5–10% on top of the agreed price. Understanding exactly who pays what — and how these costs are typically shared — prevents expensive surprises at transfer.

Complete Cost Table: Buying a Condo in Thailand
| Cost Item | Rate | Who Pays | On $200,000 Condo |
|---|---|---|---|
| Transfer fee | 2% of appraised value | Split 50/50 or negotiated | ~$2,000 (split = $1,000) |
| Specific business tax (SBT) | 3.3% of appraised value | Usually seller | ~$3,300 (if seller pays) |
| Stamp duty | 0.5% of appraised value | Paid instead of SBT | ~$500 (when SBT exempt) |
| Withholding tax | 1% (company) / progressive (individual) | Seller | N/A for buyer |
| Legal / lawyer fee | $500–$1,500 | Buyer | $500–$1,500 |
| Sinking fund | 500–700 THB/sqm (one-time) | Buyer | ~$700–$1,400 for 50 sqm |
| Common area maintenance (deposit) | 1–3 months upfront | Buyer | $500–$1,500 |
| Furnishing (if needed) | Varies | Buyer | $3,000–$15,000 |
Note: Appraised value is set by the Thai Land Department and is typically 60–80% of market price. This means transfer fee and SBT are calculated on a lower base than your purchase price.

Cost 1: Transfer Fee (2%)
The transfer fee is 2% of the Land Department’s appraised value — not the agreed sale price. This is important: if you’re paying $200,000 market price but the appraised value is $140,000, the transfer fee is calculated on $140,000.
Example: $200,000 condo, appraised at $150,000 → Transfer fee = $3,000 (2% × $150,000). Split equally by convention = $1,500 buyer / $1,500 seller.
Who actually pays: The transfer fee is split between buyer and seller by convention (50/50), though the split is negotiable. Some developers absorb the full fee as a sales incentive.
When it’s paid: At the Land Office on transfer day. You present the agreed funds, both parties sign, and the fee is paid before the title is transferred.
Cost 2: Specific Business Tax (SBT) — 3.3%
SBT is 3.3% of the higher of appraised value or sale price, paid by the seller. It applies when the seller has held the property for less than 5 years and has not used it as their primary residence continuously for at least 1 year.
Who typically pays: The seller. However, in some transactions — particularly with private sellers — buyers are asked to absorb this cost or it’s factored into the negotiated price.
When SBT doesn’t apply: If the seller has owned the property for 5+ years, SBT is replaced by the lower Stamp Duty (0.5%).
Why it matters for buyers: If you’re buying from a developer (who by definition has not held the unit for 5 years), SBT will apply. Whether the developer absorbs it or passes it to you is a key negotiation point — always clarify before signing.
Cost 3: Stamp Duty (0.5%)
Stamp duty at 0.5% applies when SBT is not due (seller held property 5+ years). It is an either/or situation — you pay one or the other, not both.
Example: Seller held property 7 years. SBT does not apply. Stamp duty = 0.5% × $150,000 (appraised) = $750.
This is dramatically cheaper than SBT, which is why buyers often prefer purchasing from long-term sellers.
Cost 4: Withholding Tax
Withholding tax is paid by the seller and calculated based on their gain. For companies, it’s 1% of the sale price. For individuals, it’s calculated on a progressive basis using a formula based on years of ownership and appraised value.
This is the seller’s cost and not borne by the buyer, but it affects net proceeds for the seller — which can influence price negotiation.
Cost 5: Legal Fees
An independent Thai property lawyer is essential. Services include:
- Title search and due diligence ($200–$500)
- Contract review and negotiation ($300–$800)
- Transfer supervision (attending the Land Office on transfer day): sometimes included, sometimes additional $200–$300
Total typical legal cost for a standard condo purchase: $500–$1,500.
Do not use the developer’s lawyer as your sole legal advisor — they represent the developer’s interests, not yours. Engage your own independent counsel.
Cost 6: Sinking Fund (One-Time)
The sinking fund is a one-time, non-refundable payment into the building’s long-term maintenance reserve. It covers major future expenses — roof replacement, elevator overhaul, structural repairs, and infrastructure upgrades.
Rate: 500–700 THB per sqm (approximately $14–$20/sqm at current exchange rates)
Example: 50 sqm condo at 600 THB/sqm = 30,000 THB ≈ $840 one-time payment.
This is paid at transfer and is non-negotiable (it’s a building requirement, not a developer choice).
Cost 7: Common Area Maintenance Charges
Common area maintenance (CAM) covers day-to-day building operating costs: pool maintenance, gardening, security, lobby cleaning, elevator operation, management team.
Rate: 50–120 THB per sqm per month
Example: 50 sqm unit at 80 THB/sqm = 4,000 THB/month ≈ $112/month or $1,344/year.
At purchase, you’ll typically be asked to pay 1–3 months upfront as a deposit.
Annual running cost: $672–$2,160/year for a 50 sqm unit (depending on building quality and location).
Cost 8: Furnishing
Unless buying a fully furnished off-plan unit or purchasing with existing furniture, you’ll need to budget for furnishing. This is often underestimated.
| Property | Furnishing Budget |
|---|---|
| Studio (28–35 sqm) | $3,000–$8,000 |
| 1-bedroom (40–60 sqm) | $5,000–$15,000 |
| 2-bedroom (65–100 sqm) | $8,000–$25,000 |
| Villa | $20,000–$100,000+ |
For short-term rental: invest in quality photography-friendly furnishing. Aesthetic quality drives booking conversion on Airbnb and Agoda — cheap furnishing costs you in nightly rates and reviews.
Total Hidden Cost Calculation: Real Examples

| Transfer fee (buyer’s 50%) | $540 |
| Stamp duty (seller held 6 yrs) | $270 |
| Legal fees | $600 |
| Sinking fund (30 sqm × 600 THB) | $510 |
| CAM deposit (2 months) | $150 |
| Furnishing | $5,000 |
| Total additional costs | $7,070 |
| All-in purchase cost | $97,070 |
Example 2: $250,000 Bang Tao 1-bed (New from Developer)
| Item | Cost |
|---|---|
| Transfer fee (50/50 with developer) | $1,500 |
| SBT (developer, but check contract) | $0–$2,475 (negotiated) |
| Legal fees | $1,000 |
| Sinking fund (55 sqm × 650 THB) | $990 |
| CAM deposit (2 months) | $320 |
| Furnishing | $10,000 |
| Total additional costs | $13,810–$16,285 |
| All-in purchase cost | $263,810–$266,285 |
Who Pays What: Negotiation Points
The buyer typically pays: transfer fee (50%), legal fees, sinking fund, CAM deposit, furnishing.
The seller typically pays: SBT (3.3%) or stamp duty, withholding tax, the other 50% of transfer fee.
But everything is negotiable. In buyer’s markets, developers absorb transfer fees entirely. In seller’s markets, buyers may be asked to contribute to SBT. Always clarify cost allocation before signing any contract.
Pros and Cons of Thailand’s Property Cost Structure
Pros:
- 0% buyer commission at MORE Group (unlike markets where buyer pays 2–5% agency fee)
- Transfer fee calculated on appraised value (usually below market price), reducing actual cost
- SBT and withholding tax are seller costs — buyers are only responsible for transfer fee + legal + sinking fund
- No annual property tax on residential property below 10 million THB in value
Cons:
- SBT of 3.3% is significant for sellers (and can affect net proceeds / price negotiation)
- Costs are paid in THB at the Land Office — currency exchange timing matters
- Legal fee is non-optional for due diligence — cannot be skipped
Frequently Asked Questions
Budget 5–10% of the purchase price for all additional costs: transfer fee (~1%), legal fees (~0.5–0.7%), sinking fund (~0.5%), CAM deposit, and furnishing. If you're buying from a short-term seller who passes SBT to you, add 3.3%. For a $200,000 purchase, all-in costs typically reach $210,000–$222,000.
These are primarily seller costs. SBT (3.3%) applies when the seller has held the property less than 5 years; stamp duty (0.5%) applies when they've held it longer. However, who actually bears these costs is negotiable in the purchase contract — always clarify before signing.
The transfer fee is 2% of the Land Department's appraised value (not the sale price). Appraised values are typically 60–80% of market price. The fee is conventionally split equally between buyer and seller, making the effective buyer cost approximately 1% of appraised value.
Yes — a one-time, non-refundable sinking fund payment of 500–700 THB per square meter is required at transfer. For a 50 sqm condo, this is approximately 25,000–35,000 THB ($700–$1,000). It funds the building's long-term maintenance reserve.
Strongly recommended. A qualified Thai property lawyer provides title searches, contract review, and transfer supervision for $500–$1,500. This is cheap insurance against title defects, unfavorable contract terms, or misrepresentation. Never rely solely on the developer's lawyer.
Thailand doesn't have a formal 'purchase tax' for buyers. The costs at transfer are: transfer fee (2% of appraised value, conventionally split), and potentially SBT (3.3%, seller-side) or stamp duty (0.5%, seller-side). Buyers are directly responsible for the transfer fee portion and legal costs.
