This plus the fact that the building is in a rather poor state leads me to believe that the revenue from the HOA fees and coined operated laundry machines may be going in someone's pocket rather than in maintaining the building.

I plan on putting down new rules and cleaning, painting, and buying an o zone machine for when people move out.

I'm not afraid to get my hands dirty and work hard to create an unearned income machine for myself.Any advice on the best way to go about purchasing this property?
