Yes.   Until a foreclosure action is completed, a new deed issued and ownership transferred, you retain all rights as a property owner.   No one is permitted to trespass on your property or to insist that you allow them access.   However, during the time a foreclosure action is pending, it is wise to undertake the following actions:

• Seek legal advice since foreclosure is a legal proceeding
• Follow the progress of your case on the common pleas court website
• Begin making the important decision:   Can you afford the house or must you move on.   If you believe you could afford the premises, and that you experienced a "one time" drop in income, you should work hard to reach an agreement with your lender or round up enough funds to "reinstate" your mortgage.   If you cannot afford the home, you should carefully explore a sale.
