Hi missb and welcome to the forum
Well full credit to you trying to broker a settlement directly with your creditors. It is a shame that they will not accept your offer, which would ultimately give them more money as there would be no professional fees to be paid.
I am sure that given the figures you are quoting that an IVA based upon an equity release is more than feasible. I do a lot of these types of proposal, and they are relatively popular with the creditors who get paid a lot earlier than they would under the alternative bankruptcy proceedings. The costs are also significantly lower.
