Quote from @Chris Seveney:I've seen some big ones in the news, but they are always for large investor slumlords that have egregiously ignored the law (and warnings) for a long time, or Landlords that are downright evil (sexually assaulting women, physically attacking Tenants, etc.).The best protection: know and obey the law, treat your tenants honestly and fairly. 400 rentals under management, 13 years, and I've never been sued.

Our stated criteria:Our Criteria:We do not deny housing for race, color, religion, sex, national origin, handicap, sexual orientation, marital status, or familial status.We do deny housing to individuals: when the application is not complete or accurate where there is no sufficient income/resources to pay rent and livewhere there is poor prior tenancy: evictions, violations, damage to rental property, poorly handled move outs, amounts are still owing to landlords or utilities.Criminal activity is at our discretion depending on severity, number of convictions, and how long ago.
