I'm comfortable with the obvious #s (ROI, yield), but my concerns are (1) figuring out whether the house is "on the right side of the tracks," (2) if there are any big ticket purchases (e.g. roof, water heater) that are required or impending, and (3) what the local economic prospects look like.  

It caters to pilots and flight crews.

Its like having a friend hit money on a scratch ticket, just because they did does not mean you should run out and buy one.

The owner is very sick, has no internet and says he only learned about that 2 days ago.The team working for the person with the POA rehabbed the property They remodeled the kitchen and fixed some other smaller ticket items like leaking toilets, etc.

Expand this to all other negatives like main streets, near railroad tracks, near commercial units, under airport flight paths, no garages (this may not be the case in all areas), no yards, poor layouts that can not be laid out differently, too many steps leading to the fr t door ( I just learned this harsh lesson a year and a half ago), etc. . . . .As far as the foundation issue, that was actually a good thing.

Also points don't expire, bags fly free, and if you use points to purchase tickets, they have a great cancellation policy.If you do decide to do this, please message me first and I'll send you my affiliate link.  

There were a few issues here and there but never any big ticket items.

The site borders but is not in the flight path of a jet capable airport.My wife and I are just turning 60 and have not been real estate investors having once lived on this land.

I'm trying to see if there are any available tickets. 

I started with them a few years ago and my points have paid for almost 30 tickets and I still have 500,000 points left.
