Most mortgage lenders will require you to put down a minimum deposit of 5%. This amount is based on the property value you are looking to buy in Wolverhampton.
Sometimes, you may be asked to provide a larger deposit for your mortgage in Wolverhampton, such as 10%-15% of the property price. This may be due to your credit score. If you have bad credit, you may have missed payments in the past or have unsecured debt in your name; remember that a mortgage is a loan, a huge loan, and they will not want to lend to an applicant that may be unable to meet their repayments. This is why they ask for a higher deposit, to prove your reliability.
