Is there a limit on what you can charge as an application fee?  

I only lease 2-3x's a year and end up using mostly Zillow / Experian for the listing, application and screening.

For a co-signor we require a full application, screening and 4x the rent

How will you advertise, show, and screen applications?

In a purchase, it's declared by the borrower on the application.

I've been hearing 'horror' stories of business (even large ones) ditching the Austin area...and Elon taking back is application to be part of Austin proper.

tenant pays an application fee and you can pro-rate pet rent based on their "FIDO" score.P.S.S I'm not affiliated with them at all, I am just a PM who uses their service and had good experience with them.https://www.petscreening.com/
