When you are screening tenants for your rentals, it is pretty easy. You take an application, submit it to a screening company and wait for the results. You have pre-set tenant selection criteria, and you compare against the criteria. You let all the incoming prospects know what you are screening for, and you let them self-screen as much as possible. After comparing the results to your criteria, if the tenants pass, you accept them. If not, you move on to the next applicant.
