We do this annually with all proceeds going to our charity of choice. We sell stuff from abandoned units as well as our customers set up tables and sell their stuff. I have never seen anyone sell their items and move out - they end up buying things from us and other tenants and put them in their unit - I am sure most don't even come close to emptying their units - LOL! As well we do hot dogs, pop by donation and sell boxes cheap so people can cart their items out. We actually open the fire gate and have everything at the fron of the property - have never had any issues with "non-tenants". As well the community knows we are hosting and they all look forward to it! It is great fun for the staff as well!!
