I think I've messed up and I need some advice. Dh and I have just had a mortgage agreed in principal. We don't currently have a joint account. I know that you shouldn't apply for any credit or financing during the mortgage application process and I haven't but I have foolishly applied for a joint account with the mortgage lender. Now I'm afraid that our mortgage application will be rejected. I'm so stupid, I just got a bit over excited and wanted to get everything all set up. Will this affect our mortgage? I think our credit scores are good and our loan to value is about 60% so we have a big deposit. Any advice/reassurance/brutal honestly would be appreciated.
