Mortgage enquiry?

I really want to buy a house on my own, but i really want to know within what price range i should be looking at. how do they calculate the amount of mortgage you can borrow.
Answer
The amount of deposit you can offer is usually a nice indication. as a first time buyer you would porbably be required to make a 5% or 10% deposit on the property. if you are limited on the deposit you have then this will limit the size mortgage you can have anyway. if i were you i would make an appointment with a mortgage advisor (they are usually free and no obligation). make sure you take along all the relevant information (i.e wage slips, details of mortgate payment you could afford each month, detais of deposit you have) they will be able to advise you on a) whether you could get a mortgage and b) what sort to go for. we are first time buyers on a £150,000 house. we put down a 10% deposit and our mortgage is £750 per month (based over a 25year period).
