Best app for rent collection

[Brian Shelton]

Most of my units are managed, but i am buying a 4 plex my son will live in with 3 roommates at college.  He will manage it but i want to automate the rent collection and late fee assessment.  Would be nice if they also had sample forms available, leases and such.  I've heard mixed reviews on Cozy and also they are being acquired by another group i know nothing about.  Appreciate your thoughts.
