Technically the owner is still the legal owner up until the house goes to sale at an auction. then from there, if there are people sitll liveing in the home, the evictions process begins. tenants have 90 days notice to quit, after the 90 days, if tenants are still in possession of said property, a complaint is filed with the court to obtain a hearing date. at the hearing date, the attorney for the bank will go in with a writ of restitution to obtain a lockout date. if no one (on the defendants side) shows up, the judge will usually sign an immediate writ. if someone shows up and asks for more time, the judge will usually give more time.
also note, that the agent for the bank may offer a Cash for Keys Relocation Assistance. this is when the bank offers you a certain amount of money to move out by a certain amount of time. lets say for example they'll give you $2000 to move out in 30 days. and you basically have to leave the home in broom swept condition.
But anyways back to you paying your rent, if you don't pay your rent to him, and you know he's in default, you still have to pay rent to him because he is still the owner of the home. if you fail to pay rents, he can summary evict you for non-payment of rent. which usually takes like 3-4 weeks to be complete.
