I paid a security deposit of $650 when I moved into the house I rented from my landlord. I moved out February 3. It is now March 22. I have heard nothing of getting my security deposit back, nor have I had any letter telling me what my deposit was used for. I was told by a friend that if I do not receive a written letter within 30 days of moving out, that I am entitled to a full refund of my security deposit. Is this true, and if so, how do I go about getting it back?
