I spoke to a fellow investor friend of mine earlier today and while he is somewhat of a "doomsday prepper" he had also predicted the real estate market crash back in 2005. 

Invest in a cheaper part of town (or a different state) - I've definitely thought about this and read the various posts about it, but cheaper part of town, I weigh the heightened risk of getting lower quality tenants, slower appreciation in value of the property or DEpreciation of property value when a market crash hits.  

(again i'm not saying to they will crash, but they will come down until they see some traction and that is where they will stabilize)

I remember having perfect W2 income and credit and preparing for the required refinance at 5 years, then the 2008 crash happened.  

When market tanks like that, we are susceptible to a complete market crash.  

One morning the tenant got up and went into the kitchen to make coffee, she heard this loud crash.

I live in a similar market (LA) and I buy out-of-state.As far as choosing markets and teams and such, well first for the markets-https://www.biggerpockets.com/renewsblog/out-of-st...Of the markets you mention- Dallas is really expensive now and returns are minimal (prices there are higher now than before the 2009 crash), Austin doesn't cash flow as far as I know, and Houston got pretty short on inventory over the years with all the investors buying it up and cash flow is squeezed there now too.

When this all comes crashing down in the next 5 years is what I assumed Dan was saying, yes. 

Constant App crashing, poor navigation features, missing/ non-contiguous data from web to mobile.
