Hidden Costs of Buying Property in Thailand: Taxes, Fees & Due Diligence

The sticker price is never the final price. Budget an additional 5–10% on top of the purchase price.

One-Time Purchase Costs

| Cost Item | % of Value | Paid By | |-----------|-----------|---------| | Transfer fee | 2.0% | Usually split 50/50 | | Stamp duty | 0.5% | Seller (unless exempt) | | SBT | 3.3% | Seller if sold within 5 years | | Withholding tax | 1.0% | Seller | | Mortgage registration | 1.0% | Buyer |

Professional Fees

Legal fees: 30,000–80,000 THB
Engineering inspection: 5,000–20,000 THB
Appraisal fee: 3,000–7,000 THB

The Appraisal Gap

This is the most painful hidden cost. The Land Office uses its own appraised value (almost always lower than the purchase price) for tax calculations. If the bank's appraisal matches the Land Office, you need a bigger down payment.
