Hi, I hope this works out for you, I can think of three possible solutions:
1. It sounds like your only reason for going with GE Money originally was being self employed (did you self cert your income?). If you have business accounts organised at this stage, or even if you can get an accountants certificate completed for the lender, you should be able to apply through a prime bank.
2. If possible, can you get anyone else, PAYE or long term self employed to support a prime mortgage application with you? Maybe their income will get you over the line.
3. Last resort, try Springboard Mortgages, yes they are sub prime, but the rate should be lower than what you are paying at the moment, and they are part of the Irish Life group. Even Start would probably offer a better rate than 8.2%.
With the recent withdrawl of GE from the mortgage market, I'm not sure how competitive their rates are going to be from now on, but I think even with the cost of moving, it would be worthwhile. With the falling house values, a lot could depend on your loan to value. It would probably want to be 75% or less. Also make sure when applying to a prime lender that they are aware that you went sub prime as you were self employed, very different to having missed payments on previous loans.
