To obtain property development funding from Signature Property Finance we require a 35% deposit of the GDV (Gross Development Value) or 20% of the associated costs, whichever equates to a lower loan amount. As an example, a development with a GDV of £1 million would require a deposit of 35% (£350,000) or 20% of the costs associated with the development. If the costs only equal £250,000, you will be required to provide £350,000 as a deposit for your development finance.
