Two - I was over 40, which isn’t necessarily old, but seems ancient compared to the many 20-somethings who dominate BiggerPockets. 

Really this strategy is ancient.

I was able find a bank to give me a $30k business loan secured solely by my "business assets" which at the time consisted of a single office chair and an ancient computer...Might be another avenue worth exploring.

If I was forced to not "invest" this money and do something "fun", I'd probably travel to see the northern lights, maybe alaska to go fishing, egypt, etc.

I’m really glad @Jim K. responded on ancient wherever.  

But based on my ancient memory of the greater SD area, I cannot imagine that you are pulling any tech job related tenants or even military out of Miramar. 

The only septic system I've replaced was ancient (the tank was made out of bricks) and that was pretty inexpensive considering...

Recent visits to Egypt, Antigua, Austria and the Canary Islands, skiing in the Alps, and livin' the life in Portugal. 

Makes no sense to look at ancient days when trying to analyze a modern-day housing crisis. 

The owners usually slam crappy tenants in and then claim the property is stable after 1 year etc. with minimal repairs and the expensive stuff to replace is ancient.
