I rent a house in Florida that just want into foreclosure . Do I need to pay the landlord the monthly rent.

Yes you do need to pay the rent; even if y ou have no one to send it too, put it in an escrow account then no one can come back at you for non payment.

Tick

Until notified otherwise you keep sending the payment to the same place as before. Foreclosure may effect your lease shortly depending on who will own the property
