Have you found value in an "Apartment Manager Certification"

[Drew Berman]

Hey BP Family, 

Wondering if anyone has found any value in getting a certification as "certified apartment manager" or any similar certification.  The association I am looking into (link below) provides a credential and a badge you can display.  More so I am interested in seller financing and feel this may be a way to gain a sellers confidence in my ability to manage a property, and eventually down the line raise OPM.  Having a hard time justifying the $1500 course for what seems to be pretty common info.
