Are property appraisers licensed in Thailand?Not through a single unified national license the way architects or engineers are. There is no one body issuing a mandatory 'appraiser license' that covers every valuation purpose. Instead, accreditation is purpose-specific: valuers who value assets for public companies, IPOs or capital-market transactions must be approved by the Securities and Exchange Commission (SEC), and valuers used for mortgage financing must be on the specific lending bank's own approved panel. Voluntary membership in bodies like the Valuers Association of Thailand (VAT) or Thai Valuers Association (TVA) signals professional standing but isn't itself a government license.
What's the difference between a bank-panel valuer and an SEC-approved valuer?A bank-panel valuer is accepted by one or more specific commercial banks to produce valuations their credit teams will rely on for mortgage lending — each bank keeps its own list, and a valuation from a firm not on your lender's panel may simply be rejected for financing purposes. An SEC-approved valuer is authorized for a narrower, regulated set of purposes: valuing assets involved in public company transactions, IPOs, asset revaluation, or transactions requiring disclosure to the Securities and Exchange Commission. Most individual buyers only need a bank-panel valuer; the SEC list matters mainly for developers, public companies and fund-related transactions.
Why would I need a property valuation as a buyer or owner?The most common reason is mortgage financing — your bank will commission or require a panel valuation before approving a loan amount. Other common purposes include insurance (setting rebuild/replacement value), probate or estate settlement, dispute resolution or litigation, and periodic tax-base assessment. Each purpose can call for a different methodology and sometimes a different type of accredited valuer, so confirm the intended use before commissioning one.
How do valuers actually calculate a property's value?Three methods are standard, and a competent valuer will tell you which one applies and why. The comparable-sales approach — used for most residential condos and houses — benchmarks against recent, similar transactions in the same area. The income approach — used for rental and commercial property — capitalizes expected net rental income. The cost approach — used for unique, new, or non-market properties — estimates land value plus depreciated construction cost. Ask for the comparable transactions or income assumptions behind the number, not just the headline figure.
What should a valuation fee look like?A legitimate valuer typically charges a flat fee based on the property's value tier and the complexity of the assignment, agreed before the work starts. A fee that varies with, or is a percentage of, the appraised value is a significant red flag — it creates a direct incentive to inflate the number, which undermines the independence the whole exercise depends on. Ask for the fee in writing before engaging anyone.
What red flags suggest I should question a valuation?A fee tied to the appraised figure rather than a flat rate; any financial or referral relationship between the valuer and the selling agent, developer or your own broker; a report with no stated methodology or comparable transactions behind the number; and inability to confirm bank-panel or SEC-approved status when that's specifically what the assignment requires. When financing is involved, always confirm directly with your lender that the valuer or firm is currently on their approved panel — panels change.
