your best bet is to go and see a financial adviser, but be carefull there are a lot of bad ones, you can tell the difference a good finacial adviser wont charge for his services so you have nothing to lose,there are many levels to which mortgage companys work, if you are clean as a whistle they class you as a prime borrower, if your credit is slightly flawed you will be a sub prime borrower but if your credit is bad ccjs ect then you can still get a mortgage but the interest will be quiet high,and the lenders tend to charge you higher costs for taking the mortgage out, hope this is of some help
