How much could I borrow

[Summerwood1]

I'm a single mum,I earn £25,000 a year,any idea based on that figure of what price house I could buy on a mortgage?

For a vague idea try using something like this
calculator
Or type mortgage calculator into google. A fair few banks have them to give you a general idea.

It could be worth having a meeting with your regular bank and asking the question. Lending criteria vary from bank to bank and there has been a recent change which takes into account your regular outgoings and other commitments as well as your income and credit score. I suggest your regular bank because they have access to your accounts which saves a little time
