Advice needed. Best background check and or tenant mgmt system

[Tia Mitchell]

We have been burned a couple of times now, I used checkthem.com to screen before and it didn't show multiple evicitions on either party, after the aforementioned tenant's recent eviction, I am screening once again.  This time I used Cozy.co background check service and it failed to uncover a prospective tenant's eviction and bankruptcy.  So... I am reaching out to you all for help!  Who do you use, and if there is an all in one system, like cozy, that actually does good background checks... What is it?  Thanks!!!  (Side note, only 8 units so the bigger ones won't take us.  Ie: appfolio/yardibreeze)
