Hi, in principle the answer is a resounding yes. There are a number of banks who will lend more than the value of a property, up to 125% or more infact. The best known lender for this type of mortgage is Northern Rock, though BM Solutions (aka Birmingham Midshires) have also recently launched a similar product. Coventry Building Society and Mortgage Express also offer 125%+ products.
I'd suggest you seek an independant mortgage advisor who you trust and who won't charge you too big a fee (over �695 is getting a bit high!) to arrange it all for you.
If you want to work out how much you can afford just take your annual gross salary (before tax is taken off), subtract your annual loan repayments (monthly payment times 12) then times what's left by about 5. This is the absolute maximum you could borrow.
Therefore, if you earn �25,000 and pay �200 per month on debts it leaves �25,000 - �2,400(�200 x 12) = �22,600. This times 5 equals �113,000. So, if you bought a property for about �103,000 you'd have �10,000 left over if you went to the maximum.
I wish you the best of luck!
Warm Regards,
Dan
