They're supposed to limit an LLC member's legal responsibility to just the LLC.

So if you look at furnished finder etc to find travel nurse rents, and look at area long term rental rates for the area you are considering you will get an idea of what will work financially. 

@Evan Greenfield a Bigger Pockets Jacksonville FL/NE FL meetup is great idea.  

Do you have an idea of what areas of the country they are targeting?

The idea is to identify top performing listings based on recent demand (and copy-paste their strategy).2/2 units have been used to narrow down the analysis and see their performance.

I like the idea of investing in these parts best because while it is a commute I will still be able to visit the property when necessary.

Lastly, even if the "on market" prices for rental properties are really high in the area you want to invest, who said that you have to limit yourself to only "on market" properties? 

I like the idea but you forgot the cost of the internet service for the router which should cost approximately $50-$100 per month depending where you live.

This is where offshore trusts, family limited partnerships, and Lichtenstein Corporations come into play.  

Common criteria may include, but is not limited to location, prices, property type, size of the property, or age of the property.
