Borrowers need a 5pc deposit and must take out a mortgage to cover the remaining 75pc of the cost of the property. After the five-year interest-free period ends, borrowers will be charged a fee of 1.75pc of the loans value. This fee will increase every year at 1pc above inflation. These fees only count toward the Government loan and come on top of the mortgage repayments. Borrowers must pay back the equity loan when they sell the home or at the end of the mortgage period - whichever comes first.
