Get advice from a mortgage advisor to see how much you could borrow, what deposit you’ll need and what your interest rate will be. Make sure they know you’re considering a shared ownership home. They’ll need to understand your financial position – your household income, any debts you already have such as loans or credit cards, as well as the money you need to pay out every month, including things like child maintenance payments for example. They’ll use this information plus insight into your credit score to find the right lender(s) for you. How much money you have in savings to put towards your deposit will also influence the percentage share you can buy.
