Hi
Did you mean £245000 ?
There are some 90% mortgage deals. See the MS guide http://www.moneysupermarket.com/mortgages/
It may be worth going to a local independent Mortgage Broker, so they can search the market for the best deal, to meet your needs. Find using http://www.unbiased.co.uk/find-a-mortgage-adviser/
What you may find is that some lenders are more restrictive. Perhaps you current lenders are one of them.
