Sure, the housing market values may cool off, but it shouldn't crash (that's my two cents).I don't have a great answer for you. 

Again it all comes down to theming and cool factor.

It is so cool and I love it!  

@Eric Martin That’s so cool to hear!

He is partially retired now because he made so much on Austin real estate himself, but he's a cool dude and he gets RE investing.

Are you holding out in hopes that the market cools off or swinging aggressively while the homes are selling no problem? 

We all said, "cool with me!"

Add ductless mini-split units for heat and cool - $10,500Would any particular option have a greater ROI?

In a conversation that is useful because the first statement will likely get a "that's cool" response where the second will typically get a follow up question.
