Since he is short on time he is going this route for a few months until he has sufficient time to look around.

I have family and friends out there and they may also be interested in renting short & long term. 

Seems strange, but they were all installed at the same time 6 years ago so something may have shorted them out.

Next, I proceeded to get my Real Estate license and then shortly after my general contractor license.

just take a QC  and transfer the legal description from current deed.. and have your relative deed to you. and if there is a place for consideration just put 10.00... its on the county transfer form that you need to describe its between relatives not on the deed itself.. at least I have never seen it on a QC and I have done them in many many states.

And under the description of that abbreviation it says Term Dec Interest and nothing else.

Also should I be worried when researching on Airbnb that the market seems to be flooded with multiple Airbnbs in that area or is that a good sign that short term rentals are a hot commodity?

Rightly so I would guess based on the description of them that you have provided. 

We also try not to go out too far for rehabs so we get in and out in  a short time.

By the last year of our marriage, we had sold our vacation home at a $100,000 loss, lost our primary residence in a short sale, and moved to successively smaller rental homes.
