Unless the market is appreciating rapidly, so that you can pull the equity out to reinvest, seems like this would be an ultra conservative way to park money.

It sounds like you understand the financial impact of the investment you are targeting, but are willing to make it because of your conviction in Dripping Springs and need for an ultra low maintenance investment. 

These people are ultra rich psychopaths who have nothing left to do but fulfill a destiny that was forged a long time ago.
