Might have to look into this...I'm still over here getting a new card for the $200 off of $500 in the first 3 months and borrowing free money for a year lol I've always done cash-back and just make sure I use the card w/ the highest percentage for whatever I'm buying - I think Amazon is 6-7% back (depending how how fast you want it delivered), Wal-mart had a good one (5% back) there but I believe their partnership w/ CapitalOne just ended, Costco has a good one (4% back and I think 7% on gas). 

With all of these crypto-currencies, which one is going to 1)be accepted by the world-wide banking industry, 2)be accepted by the regular man on the street that wants to buy some gas at a gas station, groceries, clothes, etc.

Just musing ahead 10 years or so.With states now mandating the phase out of Gas/Deisel cars  How are MF owners going to attract and keep tenants that will now have EV's in the next 10 to 20 years ? 

People had no idea what to do at stop lights, gas pumps didn't work and those that already pumped gas couldn't pay because the attendant couldn't take cash, the lights were out in office buildings and hotels, grocery stores were worried about frozen and refrigerated food going bad, theme parks had people stuck in rides screaming to get off.

Add a very diversified economy here with banking, insurance, oil and gas, education, three medical schools, 3 law schools, life sciences, DFW airport, and so much more, it looks like the growth just goes on and on.As far as appreciation goes, that's always tough to predict. 

Gas going to be closer to 5/gallon than 4... car insurance probably 150 or so.

I definitely don't make any money off the place, but the airbnb rentals pay for maintenance and my gas driving to and from WA :-) Question: Have any of you missed some either obvious or not so obvious red flags that would have caused you to negotiate or walk away from the deal and if so what were they?

Irony of your analogy is that oil and gas production needs to drill many holes to succeed. 

Electric and natural gas service may not be discontinued while you are in possession of your unit.

Beside RE, am also interested in gas/oil.
