One of the main issues stopping prospective homebuyers from getting on the property ladder is the deposit requirement. This is especially the case if you’re already paying a high rent, making it almost impossible to save for a deposit at the same time.
Certain mortgages are designed to help first-time buyers meet lenders’ affordability criteria, which removes one financial obstacle. A joint borrower sole proprietor (JBSP) mortgage is one of these.
With this type of mortgage, another person – usually a parent – applies for the mortgage with you and is jointly responsible for making the monthly payments. This is different from a joint mortgage in that the property deeds will be in your name only.
