What is that product/device that BP endorses for when you have multiple units on one water line and you want to effectively sub-meter it and bill it back to the tenants? 

You'll know exactly how much you have to work with, and your locked and loaded for any deal that comes your way. 

If I were a guest and discovered one of those devices in the rental, the first thing I would do is unplug it.

When you have a flip property in a questionable part of town, are there security device options without having to call an internet provider out and set up a full blown wi-fi network? 

My area is seeing a lot of growth from out of state and thought it would be great to have a nice welcome letter as well as a handbook for specific type of questions (how to use the fireplace, How to use and program the auto lights, How to program the automatic schlage lock, favorite local restaurants, etc) When we bought a home several years ago the sellers left us a note as well as a bottle of wine and to this day we still talk about that for a first impression.

We are able to get a 25 year amortization and 10 year lock on our portfolio loans, with a max 1% rise after that up to a total of 6% by year 16.

Basically, will the economic harm being created by the lock downs be worse than the disease itself?

The physical work part involves cleaning out units after people leave (and leave trash), mowing the grass, maintaining the fence and security cameras if you have them, over-locking unpaid units, conducting auctions to enforce your lien. 

This is due to the fact I am moving (back) to the area to buy and while I have a job locked in, I have not started the job yet. 

Rates moved sharply higher last week, erasing months of declines and putting pressure on you (and other investors) to move hastily to lock in cheap financing.
