The purchase price clause should clearly set out the total amount payable, and the currency and country of the currency, e.g. USD. The clause can also set out payment terms including the amount payable on closing, the form of payment (cash, wire transfer etc.), dates for payment of installments, any vendor-take-back loans or promissory notes, and the interest rate on installments or delayed payments and loans. The clause can also specify the source of payment, e.g. by loan from a financial institution, or by amount for each purchaser if there are multiple purchasers.
