To answer your first post - which I assume is the one you want answering -
a) Technically the creditor, if they get their charge secured, could take possessory action against the property, but it is unlikely that the Court would grant this if you had made a fair offer of repayment.
b) If you go get a charging order you will need to provide for a monthly payment to that creditor within your income and expenditure account.
Why is your IP taking so long to put the IVA proposal together?
