For instance, I know that Verizon would have their door knockers basically circle the block to re-knock on the doors not answered whereas other companies would just come back to the neighborhood a month or so later.How would you structure a Real Estate Investing door knocking campaign and presentation looking for Flips/Rentals, Listings and possibly subject to deals? 

There are fleet trucks (verizon, etc.) that are being unloaded by those companies and have been on a maintenance schedule. 

The idea is to lease the space to a store front tenant like Verizon, AT&T, Dunkin, or something similar and secure a long term lease.Here's what I understand so far:- Work with a commercial retail broker that can bring leads.- It could be a long process - but what is long?

If your STR has a data-connection (verizon, satellite, Comcast etc.) then simply providing and wireless access point is simple. 

I looked into T-Mobile and Verizon, but they are not offering it in that neighborhood.

You have a prison that employs 2700 mostly 6 figure employees,  Kaiser and Dignity Hospitals, Cal ISO, Verizon,  Safe Credit Union corporate HQ, etc     

While I was excited to leave my job as a Regional Sales Manager for a large Verizon retailer, I realized was that I had just bought myself another job.  

Alternatively, you could also look into a wifi signal booster in both homes OR you could also get more than one router for the same connection (Verizon does this) 

Verizon  keeps installing new boxes wherever because they don't want to check a line.

I only pay for Wi-Fi $40 a month through my Verizon carrier.
