Steve.
1. Get a new Lawyer
2. Failure to pay rent is a default on your Agreement
3. You do not have "Dibs" on this property
4. I read something about "shorting"...it may exist locally, but is not a recognized activity in RE except for stocks
5. See #1..pay your rent to a new Lawyer through an Escrow-type account...But pay your rent
I don't know your circumstances, but Lenders are looking for good people that have a history of paying on time without defaults
