Or should I just stick to transit transportation? 

One of the bigger expenses is going to be transportation as they need to truck each one individually.  

I live locally, have transport and an iPhone for pictures. 

That said, long-term rents remain solid across the state due to restrictive rural/agricultural zoning, a substantial lack of new housing supply, and the added cost of transporting building materials 2,500 miles from the mainland.Only other thing I will say is that if your plan is to do long-term rentals, expect a lot of tenant churn.

I make sure he has transportation to the jobsites.

Unregulated tanks do not have to be removed and in a competitive market, lenders will not want to impose costs on a borrower that would make then uncompetitive. they make $$ making loans, not turning them down. 

You have five people to transport so even a large truck will be at max capacity.

The added cost of transportation is prohibitive unless you plan on scaling significantly.

Lubbock is also highly diversified being the hub for the area from Amarillo to Midland, Hobbs to Sweetwater for agriculture production and research (cotton, peanuts, sorghum, wheat, watermelons, and wine grape vineyards -70-80% of TX wine grape production comes from this area-), medical care and research (two top-tier facilities in Covenant and the university hospital), manufacturing, transport (major airport), and of course Texas Tech is a huge economic driver employing many thousands and bringing tons of students in with their parents money (30k+ enrollment I believe, it's enormous).

(They never did any tile because it can crack in transport, so for subway tile, it's not a good idea.
