Asheville has just recently started to feel like it's beginning to come back online, but a long ways to go for a full recovery.

I just can't find ANYTHING online that isn't from Chris or his team. 

Review their online financials/annual statements.

I just looked online and saw that in Seattle for months to month lease the landlord is only required to give 20 day notice.

Go to Etsy and search for "rental property tracker," and you will find hundreds of nice spreadsheets to track 10-20 rentals, usually for under $10.Software has extremely helpful features like online payments, marketing syndication (click a button, and your property is advertised on multiple sites), electronic document review/signing, maintenance tracking, and owner reports.

In my experience, most of the online calculators are just taking an educated guess for you.

Is the information about “In MA, tenants generally have 30 days to pay repair costs...” available somewhere online? 

The use of online classes has been increasing every year and are projected to continue to increase.

check the local municipal code, most are online.

It seems you are falling for the alarmist rhetoric you’ve been reading and watching online.
