Another idea, call the fire station near your property. 

The remainder of the town only has a Subway and a Wards and 2 gas stations.

A pretty nice place to be stationed. 

I host a monthly meetup, always the last Thursday of the month at Zeppelin Station.

Im in College Station which is similar enough to Lubbock that I feel comfortable giving this advice. 

I am also looking into a self service Amazon hub and other self service stations. 

I really think the " QUESTION" is do you raise rents... if you do you keep up with inflation, if you don't your a charity,, Does the gas station at the corner care if you drive a beater or a new car??

water, sewer, dump station, wash station, tire covers, monthly check up service (tires, doors, plug in, propane tank fill, inside motion sensor alarm, etc).  

Q3: My personal rentals have not, but I bought in Lawton, OK because that was my duty station.

Do that an at some point you will end up buying a vacant lot that used to have a gas station on it, that still has the old buried leaking tanks and the oil change guys just dumped all their oil changes behind the shop, and you will now be responsible for EPA cleanup to the tune of 100Ks.
