But I also play FreeCell on the laptop while waiting between visitors.  

The ones we're looking to move on right now....well, I don't think I'll get screaming deals like this all the time, or maybe they're only deals to me because I'm comfortable with the area I'm shopping?

At that time there were no visitors to the home (snow was undisturbed).

If things don't look banged up they will take better care and if its well equipped you can get return visitors.

I'm currently doing that on a prospective buy and apparently the $625 I'm seeking in my area is a screaming deal.

They do take ID of each visitor and also their insurance cover any damage to our properties during the showings through their system.

I've also been concerned about having the sign in the yard because it scream "empty home" and invites the potential for nefarious activity around the house. 

I am not shy about asking "frequent visitors" and long term "guests" to demonstrate to me that they indeed live elsewhere. 

It has 5 bedrooms, so I'm thinking we can rent 3 of those out to individuals for $900/mo each to cover the mortgage plus a bit, and leave the other 2 open for us to visit or airbnb them on the weekends. 

It would scream cheap.I would suggest estimating your material and labor cost for each aspect of the built.
