    Cost of buying

    Land Office fees and taxes on top of the price. An estimate: the exact amounts are set by the Land Office on transfer day.

    Official appraisal
    ฿260,000/m² × 80 m² = ฿20,800,000
    Treasury Department appraisal, building median (฿232,100–฿281,700/m² by floor) · Registered as: เดอะ ดิ โพลแมท 39
    Asking price is 1.20× the official appraisal
    Valid until 31 Dec 2026 (the next appraisal cycle starts in 2027). Source: Treasury Department (assessprice.treasury.go.th)

    No fee relief: it needs price, appraisal and loan ≤ ฿7M.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.
