It's a HOT market right now to be in! 

It’s very hot as you are probably seeing in other markets but shoot me a dm or email and I’ll try and help

For example the last rental property we purchased we owe on it about $86K and if paid off would cashflow an additional $600 per month.Because of our household income I am worried that paying off properties would bring us into tax brackets. 

As for the investing side of things, Vegas is experiencing some major growth in real estate and even now as the country as a whole is in a slow-down or market is definitely and hot and still a sellers market which is what you're looking for in terms of appreciation.

Is this due to the varying climate of each market, hot or cold (in terms of home pricing), or could it be due to cultural mismatches with the message?

There’s major renovations that would need to happen over time like new kitchen remodels in a few of the units as well as maybe replace one of the hot water units and one of the boilers.

(One Airbnb client of mine outside Denver added a hot tub and barrel sauna and outperforms his competition by nearly 40%.)

The problem is that these bad guys are always going to exist, it's like trying to kill ants during a really hot/dry season, there are just more and more of them, and while we need to stand up to them to a certain extent, I personally don't want to give them too much of my bandwidth, I feel the world needs our talents doing the stuff we are good at.

Your lack of concern for what your lack of knowledge can do to them, hiding behind the false narrative that you are helping them with your "investment strategy" is going to land you in hot water some day.You don't need to justify your actions to me but let's just hope you don't get put in front of a judge to justify them to the courts.
