It's a bank account with a banking app that is essentially just an electronic "envelope system" but it allows you to categorize transactions from every swipe and then credit that expense from the appropriate envelope.

While I already follow up via text and email, I'm considering a drip campaign, too.I'd like to do a number of electronic follow-ups but then turn to mailing them.

All tenants pay the rent directly to me electronically.

With middle school kids who want to stay through high school.With 10 rentals we have 1 turn over in the whole bunch every other year.5) use electronic rent payment system to mail free collect rent.

I’m sure they would love for you to spend time and money in their stores. 2) When you find a trade contractor,  ask if they do electronic payment ,and what is their email.

But then Zillow allows you to do all the documents electronically, and to collect rent electronically so I've had nothing but good experiences with it.

To that point, most mortgages are backed by the US Govt and most mortgages are paid by check through the mail or by electronic transfer which adds bank fraud to the charges (all of which involves the interest of the Feds.)
