RentRedi’s syndication marketing helped us secure a great tenant in under four days, including employment and landlord verification, as well as criminal, credit, banking, and eviction history checks.

I've only evicted a tenant through the court system three times in the last ten years, but I remove about a dozen tenants every year outside of the court system, all legally.Any tenant can move out in two weeks.
