    Treasury Department appraisal, building median (฿83,600–฿108,300/m² by floor) · Registered as: เดอะรูม สุขุมวิท 21
    Asking price is 1.87× the official appraisal

    Relief applies: 0.01 % transfer and mortgage fees for Thai buyers when price and appraisal are ≤ ฿7M (until 30 Jun 2027).Taxes are the seller's by custom, but it's negotiable: some sellers ask for a price "net" of fees.Individual sellers: on the appraisal, less a deduction by years held, at progressive rates (max 20 % of the price). Companies: 1 %.Estimate for guidance only, not tax or legal advice. Rules as of September 2026.
