1. Tell the lien holder that the bank can foreclose the property. In this case, the lien hold would not get anything. Now if the lien holder agree, he can get a few thousand dollars. I successfully persuaded a lien holder to accept $5000 for a $35000 lien.
2. Tell the bank to pay the amount you agreed with the lien holder from the sales price.
Then you can still buy the property with your total price.
