I am assuming you are a tenant and someone just told you to pay your rent to them going forward. You should ask this person to provide you with a copy of a signed court order that shows his appointment as a receiver. The court order should explain exactly what this person is allowed and authorized to do. You asked if the owner is still the owner during foreclosure - The answer is yes - BUT lenders usually ask for the right in their mortgages to collect rent IF the owner fails to make their mortgage payments. Lenders usually do this through a receiver who must be appointed by the court. You as a tenant don't want to be caught in the middle. Follow your lease UNTIL you can determine that a court order instructs you otherwise. If you are still unsure - contact a lawyer who can advise you further how to protect yourself.
