as Gok says you won't get a mortgage anyway, a potential lender may lend to your partner alone if he/she satisfy their lending criteria. You may be able to mend your duff credit rating by cultivating a clean record over some years, the best way to do this is to get a credit card and buy something each month and pay it off each month, this will create a good credit history over time. If you do this while you wait for property prices to reach rock bottom you should be ok.The only problem is going to be getting any credit at all initially, lenders are very weary of bad debtors.
