    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
    ฿81,200/m² × 60 m² = ฿4,872,000
    Treasury Department appraisal, building median (฿79,100–฿84,200/m² by floor) · Registered as: คอนโด วัน สยาม
    Asking price is 1.31× the official appraisal
    Valid until 31 Dec 2026 (the next appraisal cycle starts in 2027). Source: Treasury Department (assessprice.treasury.go.th)
    Transfer fee (0.01 % relief)· split฿487

    You pay on top of the price฿244
    All-in for the buyer฿6,400,244
    Seller's taxes and fees฿127,764

    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.

    LocationApproximate: this source doesn't publish coordinates, so this is Condo One Siam condominium's location taken from other listings.

    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.

    Net rental yieldWhat's left after the recurring costs of actually letting this unit out, on top of the rental estimate above.No fee reported for this project: estimated from similar buildings nearby.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.
