When purchasing a new property in Spain, you will generally be required to make staged payments. These staged payments vary, depending on the developer. Typically, 20% to 50% will be required within 30 to 60 days of signing the contract. The balance is paid upon completion and the signing of the deeds.
However, before you enter into any contract you will be informed of the dates and amounts of any payments.
On Re-sales, is common to apply for a 10 % of the price of the property before completion.
