Ask a landlord-tenant lawyer and get answers ASAP
Hello, my name is Richard and I will try to help you. Please remember I just report or interpret the law, so the outcome may not be what you hoped for.
Was the rent being paid about what other renters were paying in the area where the house is? What state is the house in? Have you now been appointed as executor of your parents' estate or has the property been transferred to you and/or your sister.
