Chiang Mai Land Appraisal Value 2026 — What Is It and How Does It Affect Your Transaction?

Many buyers and sellers in Chiang Mai are confused between the "appraisal value" and the "market price." This article explains the difference and its impact on your transaction clearly.

What Is the Land Appraisal Value?

The land appraisal value, or "government appraisal price," is the value set by the Treasury Department, Ministry of Finance, as the basis for calculating taxes and transfer fees. It is not the actual market transaction price.

Appraisal Value vs Market Price

Appraisal Value (Treasury Department)
- Set by the government, updated every 4 years
- Used as the basis for tax and transfer fee calculation
- Typically 20-50% below actual market price
- Verifiable at the Land Department or Treasury Department website

Market Price
- Set by buyer and seller through market forces
- Reflects actual supply and demand
- Typically higher than appraisal value
- Used in actual transactions

Example
Nimman area land — market price THB 200,000 per sq.wah
Appraisal value may be THB 120,000-150,000 per sq.wah
