You didn't tell us that in the original posting Sandra. This is going to be a case where you are damned if you do and damned if you don't. If you say on the form you have had a house repossessed - then you are unlikely to get a mortgage unless you go to a sub-prime lender.(posted 7258 days ago)If you put no, you never had a house repossessed and the council records show you have, then you certainly won't get a mortgage.
The best answer is to toss a coin- heads you do, tails you don't. But if you do get turned down for a council mortgage - don't give up, there will be somebody out there who will lend, albeit at a higher interest rate!!!!
