There are plenty of good renters out there, sounds like its a great time to start fresh.  

The few SFH renters on my street are generally military families that commute to JBLM (who rented blindly before moving to the area).

I started with the list of 500+ metropolitan & micropolitan statistical areas (MSAs) and narrowed from there with these criteria:Above average projected population growth (>4%)... cuts to 168 MSAs Below average vacancy for renter-occupied housing units (<6%)... cuts to 83 Below average price to rent ratio (<11)...cuts to 11 Population >500K within 25 miles...cuts to just 4 markets (btw, this cool site tells you how many people live within X radius of a location https://www.freemaptools.com/find-population.htm)Your shortlist will all depend on what "filters" are most important to you. 

I plan to require renter's insurance, but I don't want to waste money covering things in my property insurance that would be covered by the renter's insurance.Thoughts?

We were able to get new renters in  & will only have 6 days of unpaid rent which we are charging the old tenants.

IF the rent is split evenly does that mean the sub renter can put all of his things in the house next to things with the other renter?

So my thinking on why I can make it cash-flow positive is two-fold:  1) Start using a service that passes the cleaning fee on to the renter (like Airbnb), and most importantly, 2) update the cottage with modern finishes and décor where the new, professional pics will attract a much higher occupancy rate. 

They can become long term renters because it's a guaranty they'll be in town for the next 2-4 years.

I am hoping to find a resource for investigation into Commercial Property rental protection(s) from the renter's aspect.I realize this may not be the correct format, but am really looking for assistance.

You are just buying blind otherwise.Then I would go over each cost item and ask myself why it is that much and if I can cut  the amount..I would even go as far as interview renters and find out what their thoughts are about the location and the property.
