10 Questions to Ask Your Property Appraisal Company in Thailand Before Signing | Japan Valuers

May 4, 2026

In Thailand’s dynamic real estate market, a property valuation is the cornerstone of your investment strategy. Whether you are acquiring an asset, seeking a bank loan, or restructuring corporate holdings, the quality of your appraisal report can determine the success of your transaction.

However, not all valuation firms offer the same level of expertise. To protect your capital, you must vet your service provider thoroughly. Here are the 10 essential questions you should ask any property appraisal company in Thailand before signing an engagement letter.

1. Is your company approved by the SEC and the Thai Valuers Association?

In Thailand, the Securities and Exchange Commission (SEC) sets the highest bar for valuation firms.

  • Why it matters: If you are a public company or need a report for a major bank, SEC approval is often mandatory. It ensures the firm follows the strict ethical and technical guidelines set by the Thai Valuers Association (TVA) and the Valuation Association of Thailand (VAT).

2. Do you follow International Valuation Standards (IVS) or RICS?

For foreign investors, local standards may not be enough.

  • The Global Standard: Ask if the firm is an RICS-regulated firm (Royal Institution of Chartered Surveyors). RICS-standard reports follow the “Red Book,” which is the gold standard for accuracy and transparency globally. This ensures your report is accepted by international auditors and offshore banks.

3. Does your team have specific experience with my asset class?

Valuing a luxury condominium in Sukhumvit is very different from valuing a chemical factory in the Eastern Economic Corridor (EEC).

  • Expertise: Ensure the firm has a track record in your specific sector be it hospitality, industrial, residential, or mixed-use commercial.

4. Will a physical site inspection be conducted?

“Desktop valuations” are quick but risky.

  • Due Diligence: A professional property appraisal company in Thailand must visit the site. They should inspect the structural condition, verify boundaries against the Title Deed (Chanote), and assess the surrounding infrastructure.

5. How do you source and verify your market evidence?

A valuation is only as good as the data behind it.

  • Data Integrity: Ask how they find comparable sales. Do they rely on “asking prices” from websites (which are often inflated), or do they have access to verified transaction data from the Land Department?

6. What valuation methodologies will be applied?

There are three main approaches: Market, Income, and Cost.

  • Methodology: For an investment property, you should expect the Income Approach (Discounted Cash Flow). For a home, the Market Comparison Approach is standard. A professional firm will explain why they chose a specific method.

7. How do you handle potential conflicts of interest?

Independence is the hallmark of a professional valuer.

  • Neutrality: Ensure the company does not act as a broker for the same property. An appraisal firm should remain a neutral third party to ensure the value is not biased toward a sale.

8. What is the turnaround time for the final report?

In real estate, time is of the essence, especially for loan approvals.

  • Efficiency: A standard residential appraisal usually takes 3 to 5 business days, while complex industrial sites may take 10 to 14 days. Ensure their timeline aligns with your closing dates.

9. Is the report available in English (and other languages)?

For international head offices, a Thai-only report is a major hurdle.

  • Bilingual Support: Companies like Japan Valuers (Thailand) provide comprehensive reports in English, Thai, and Japanese, ensuring all stakeholders can review the findings clearly.

10. Do you provide professional indemnity insurance?

Even the best experts can make mistakes.

  • Liability Protection: Ask if the firm carries professional indemnity insurance. This protects you in the unlikely event that a technical error in the report leads to a financial loss.
