Definitely talk to a 1031 specialist like @Dave Foster to get the mechanics of the 1031 process.Sounds like you want to keep your one rental and get rid of the mountain houses.

The more expensive routers will almost certainly be dual band and have an auto-detecting feature to determine which band to assign for each device that is connected. 

You need to have a mechanism to remove tenants who are a problem, and I would strongly encourage you to consult an attorney the moment you close to get your lease terms right.

Will be experimenting with glue in ends before tapping back this time (no matter which mechanical means I find).

Hiding it somewhat was that it ebbed and flowed with the fortunes of the auto industry.  

I don't think it will be any "harder" or "easier" changing title/loan into the LLC from a mechanical standpoint, but the lender might be more willing/able if the same people were in the LLC as the original loan.

I'm sure it would've included structural engineering, but it might have included electrical and mechanical engineering as well...or even other consultants.

Get your own boots on the ground, meet the people you will rely on aka the cleaners two handmen, meps(mechanical, electrical, plumbing) contractors.

Do they think this will just happen on auto pilot and they can attain the same as me?

Fire rating, mechanical equipment and materials often change and are more expensive.
