The only thing I will say that I wish they offered within the app that they don't is a way to track mileage. 

One way we fight this is with photo verification pre-lease signing and not approving renters who don't view the place in person, our credit underwriting software also flags apps that have a high likelihood of fraud.

I use the RESPtracker app.

We currently accept rent from tenants using a variety of 3rd party apps-Cashapp, Venmo, Zelle but are moving away from accepting payments in our individual names and want to start accepting payments directly to the LLC/business accounts, but LLC accounts do not accept Zelle and there is a fee for using business accounts on Venmo.

FYI I would change the title as I read this and i thought you wanted to create an app for real estate.

From what I can tell with all the research I’ve done I need to set up the app on my phone (to see the video) while in close proximity to the camera to connect.

I do recommend on higher end properties adding TV channels and Spectrum has a live TV stream app (no more boxes, I also imagine other cable providers so as well).

Any of these real estate apps? 

You don’t need them and you don’t need an app.

btw, my tenants like the app as well.Good luck!
