need massive power close to said land.. also keep in mind they employ very few people so its not a long term thing for employment

I am fine for long term growth and don't mind working for the next 20-30 years to build a sustainable portfolio with no mortages on them as the end game plan.What would you do? 

Are they paying below market rent because the landlord hasn't increased rent over the years (eg long term tenants with no increase) or were they rented that way (ie low rent either to fill or because landlord didn't know what market rent was)?

Now is the time as my wife and I have further discussed short term rentals and such recently.

It can be done with FHA loans, short-term rentals (Airbnb), long-distance landlording, live-in flips, or partnering with family.

Question: If we have a tub in the master bathroom, but not in the hall bathroom, is that a deal breaker for turning the home into a mid term rental?

Yes absolute is a term in the industry. 

Maybe long term it will incentivize more building, but we're already building at a very fast clip. 

The long term trends with jobs and population growth are still very strong.

I would wager that if you haven't sat down and done a tax plan before, spending a few hundred dollars with a tax pro could save you tens of thousands in the long run.
