You will not even know or see your best tenants because you receive their payments on time and never hear from them. The opposite are the troublemakers who constantly cause havoc, damage property, spread rumors, get drunk, start fights, steal property, and cause vandalism. They will take a large amount of your management effort that could be spent elsewhere. If they are that disruptive to your community, you should put them on a short list, track them, and eliminate them when it is in your best interest. We once had a guy who used to walk the park all night, break into vacant homes, steal furnace parts to recycle and any other property no mater how valueless, and cause general negativity. When we eventually evicted him for paying his rent one day late, we were sure everybody knew about it. We then got praise from tenants and comments about how the park is so much more pleasant than it was in the past 5 years.
