BSD is a tax paid by the buyer on any purchase of property in Singapore. For residential property it is calculated on the higher of the purchase price or the market value, using progressive marginal rates — so only the portion of the price within each band is taxed at that band's rate. It is payable within 14 days of signing the contract (or the date of the document if signed overseas).
