    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.

    Net rental yieldWhat's left after the recurring costs of actually letting this unit out, on top of the rental estimate above.Vacancy assumes 30 days between tenants (default of 1 month — not enough history for this building yet).Estimate for guidance only: based on asking rents (not signed contracts) and simplified tax/fee rules. Not tax or investment advice.

    Flood risk:LowNo BMA-documented flood-prone spot was found within 800 m of this location.Position is this project's approximate location (median of nearby listings), not this exact unit.Based only on proximity to points BMA itself has flagged as flood-prone or flood-watch — not a hydrological model, and not the 2011 flood extent. A location with nothing nearby is not proven flood-safe: BMA's list covers the spots it chose to document, not a wall-to-wall survey.
