Ex roommate has not lived at the house or paid rent for 3 months,at end of 3rd month he gathered his stuff in the house,I told him that I will be keeping his dirt bike, street bike, and welder as collateral he makes no attempt to contact me so I put his stuff in a storage locker. When can I sell his stuff to get my money and how would I get the bikes in my name?This is going on since Oct. 06
