I heard a landlord complain that he is tired of having his tenants call him telling about they can't their neighbors. Each time the neighbors have some sort of altercation once they call the landlord they expect him to come over and resolve the dispute instead of doing that themselves. How often do you think a landlord should try to solve disputes between his tenants. Each month? Once every six months? Or should s/he tell the tenants to solve the conflicts themselves?
