Among the various things is a property management app that is adapted to local laws, will permit to create leases, list properties for rent and more.

I was thinking if they used a management app like Buildium there may be a history.

Zillow apps can be somewhat unreliable in my experience.

If you get a delay and a tenant need to move, you wasted their time and app money. 

Looking at managing apps.

We settle on our 3rd residential property in a few weeks and feel it's time to start collecting rent online or through an app.

Should I just send them a simple message over the AirBnB app?

@Benjamin Aaker sorry couldn't figure out the app to sign back in to reply, lol.

Don't put it into your bank acct (hmmm... legal issue here, the state REQUIRES a bank acct for security deposits ... so, maybe check with your attorney first).Anyplace that processes pmts will have to report and every bank acct will do so, as well (two extra numbers on the 1099 you already get that shows interest/dividends).Maybe you can get around with cash apps - of course, most of those forbid commercial pmts, such as rent (and Zelle doesn't work with my business acct at all, only with personal accts .... which gets back to the bank will report it anyway) -- if you get caught, expect to get dunned for business charges (my Paypal is business, so I don't worry about using it and have trained tenants on how to use it if they don't want fees added to their rent pmts).

I use the ICBA app to find them. https://play.google.com/store/apps/details?
