It seems like they all want to charge for ACH and Credit Card Payments. 

Eliminate debt, establish a budget, and save.

I can have them just setup an ACH for the monthly payments, etc...but I feel like this would be easier with some automation, and there just must be something that's already setup for this.

I would follow-up with a letter as others have stated, but if no action was taken I would trim off any branches that over hang my property eliminating my own liability in the situation.

*Tenant payments via ACH not deposited into a Baselane Banking account will incur a $2 fee.

What manual processes do you think AI could help to eliminate?

It's doesn't really sound like you are much into being landlords so doing a 1031 might just change from "annoying when things come up" to full fledged head aches when you buy more and or larger properties in your current market.

There could also be a change to the HOA by-laws eliminating the right to lease and alternatively if too many units are tenant occupied it could impact the warrantability of the financing which would be problematic if you wanted to sell the unit.

Also, not everyone wants to do airbnb no matter how profitable it can be, the head ache is not worth it for alot of people
