Signed contract but seller is ghosting me

[Paul Slawski]

I have a signed contract for a 6 family by the owner of the building however my attorney and his agent can not get a hold of him to move forward with the deal. I understand that the property is heading to foreclosure however from speaking with the bank, they are not involved, yet. Looking for some suggestions on next steps.  This is the first time something like this has happened to me.
