My Rental Property is being listed by someone else - SCAM Artist

[Baris R.]

I have received several call from prospective tenants informing me that my property is listed as for rent and when it is available. My existing tenants have informed me that people have come by knocking on the door and asking of the property is for rent. It appears that some scam artist has listed by property on Zillow and other sites. He also appears to have copies of my loan documents and using it as proof that he owns the property and one of the prospective tenants also sent me a copy of his driver's license showing my address on it. How do you protect my self and what does he have to gain by doing this?
