There are several forms of possible landlord fraud such as
* the house or apartment is not ready at the time of move in, or
* the house or apartment has been rented to someone else, or
* the house or apartment has no heater or water, or
* you are paying for someone else’s utility service, or
* you paid rent to someone pretending to be the landlord who does not own the property.

Check ownership on the web.

If you are in this situation, contact the Pennsylvania Bureau of Consumer Protection. You should also contact the District Attorney’s Office. You also might be able to sue your landlord under the Unfair Trade Practices Act, but you should consider hiring a lawyer to do this.
