There are several possible outcomes:
1) The estate sells the property and pays off your note. You will get the principal, interest and any other charges you're owed. If the estate gets more than enough on the sale to pay you off, they keep the excess. If not, they come out of pocket to pay you off. They cannot sell without paying you off unless you agree to a short sale.
2) The estate gives you a deed in lieu. You get the property. You wouldn't pay anyone anything. I've done this with a defaulting borrower on a hard money loan.
3) The estate refuses to give you a deed in lieu or sell. You foreclose. Around here you start the bidding at what you're owed OR LESS. I see lender start the bidding lower and file a judgment for the shortage. You could do that if you think the estate has assets.
3a) Nobody bids. You get the property. You don't owe anyone anything.
3b) You start the bidding at what you're owed and someone else wins. You get what you're owed and the estate gets the excess (after fees.) If the winning bid is below what you're owed, you might be able to go after the estate for the shortage.
3c) You keep bidding and win. I don't see this happen here, but perhaps its allowed in your area. You would pay the foreclosure trustee the full amount and get the property. The amount you're owed would come back to you and the excess would go to the estate. So, you would be out of pocket, on net, the amount of the excess. If the winning bid is below what you're owed, you might be able to go after the estate for the shortage.
You're lawyer is charging you $180 an hour. That's a pretty typical rate.
