What is everyone using for a tenant screening tool these days?

[Danielle Ratto]

We will be renting out a unit next month and haven't had to rent in a few years (yay for great tenants!). Our last vacancy we used Cozy.co for tenant screening. I know apartments.com has an application / screening process, but wasn't sure if there is something better. I've seen Innago and Zillow rental manager in my research, but not sure if there are any other hidden gems out there. We are looking for something free for landlords, as we don't have that many doors yet. What do you use? Do you like it or recommend it? 

Thanks!
