Do NOT put rent into escrow; this is not the same as paying, and will cause you to be evicted for non-payment! "Kemperk" continuously gives advice that would lead to a tenant's eviction or lawsuit.
As the other posters stated, you need to pay rent to whoever owns the house. Continue paying rent to your current landlord until you are told otherwise. The new owners WILL call you when they take possession to tell you where to send the rent. If they don't, and rent payments go to your old landlord after, say, the bank takes possession, then that is between them and your landlord. It has no effect on you.
