Hi pdd and welcome back!
Was your wife a joint owner of the property? If so, then her share of the equity will need to be used to satisfy them, leaving you with the balance to deal with your creditors.
Your proposal seems a good one, but obviously you will now need to take more detailed and specialist advice before proceeding.
I am sure that your wife will not have to sell her car in bankruptcy, so long as it is necessary for her to get to and from work.
