Shared ownership monthly repayments comprise both your mortgage repayments, and the remaining rent payments.
To give an example, if you had a property with a value of £220,000, with a mortgage interest rate of 3.54% with a 40% share over 25 years and you could manage a 10% deposit (£8,800) your monthly mortgage payment would be £398.19 and your rent would be £302.50.
Therefore, your overall monthly payment would be £700.69. As you can see, there are a lot of variables that determine your repayments. These are:
Property value
Shared ownership mortgage interest rate
Deposit amount
Mortgage value
Term (25+ years)
