Are there any good resources online to be able to get an idea of average monthly/yearly expenses like utilities, etc. for a given zip or city?

The forelcosure auctions in my home State of Florida are all online.

We use DealCheck to underwrite deals and QuickBooks Online for everything else post-closing on the purchase.Quickbooks Setup:- Classes allow for separate P&Ls for each property. - Products & Services enable us to track each 'phase' of the rehab. - Projects give us visibility on my projects- My CPA can easily access the reports for tax preparation.

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.

They have daily webinars, you can call your mentor pretty much 24/7, so it's real interaction.

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

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.

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

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