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.

Now, however, prices in Dallas are higher than they were in 2009 before the crash, but a pretty good %.

After the crash RE was a natural contrarian investment and, after doing some flips and buying some rentals, first my wife and then I got our agents licenses.  

I'm not sure what you mean by flash factor, but I hope it's not related to the flash crash in the stock market.As far as up and coming neighborhoods, accurately predicting that is similar to actively predicting stocks that will go up...

In addition, last Fall the rental market in the area crashed and a ton of apartments went empty.

I did very well in the crash, too.

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.  

I'm not talking about the person who started a business and lost everything in the crash, or the guy who has been out on his luck with a major medical expense or similar emergency.
