@Erik W., your points are very good and thank you!
1. Yes, if it was not for the government there literally would not be any jobs there. Border Patrol will always be there as Ajo is 40 miles north of the Mexican border. There is a contingent of contractors there now building the border wall but once done, they are gone. After doing more research, I can see there is a 29% unemployment rate in Ajo and from what I can see after viewing the town and the property, there is not much development going on. Ajo is a quaint little southwest town but quite isolated and not known for growth or opportunities.
2. The property is roughly 120 miles from my location. There is only one other PM in town. I was considering moving there if I were to move forward on this purchase so I would be onsite.
3. Yes the maintenance and operating costs will be higher as others have said. I have requested to see the owner's Schedule E. We'll see what happens with that.
Another thing, I have had 5 banks and credit unions turn down financing because of the location and lack of growth but two "alternative" financiers interested. Probably not a good sign either.
I am seriously thinking this is not the best investment.
