I got burned in the crash of 2008, but never lost my affinity for real estate. 

It doesn't account for national-level issues, such as the bubble and resulting crash back on 06/07 where unemployment spiked.

The other part of wholesaling that is a possible red flag is Equity Stripping, AKA Illegal Flipping, this was heavily regulated till a few years ago by lenders, especially M.I. companies, they have relaxed the rules, but was a problem pre and post crash. seeing the increase in this activity seems eerily familiar,  like 2007 all over again. just be careful especially with your license, Disclose Early, Often, and in Writing, My license is too valuable to me to be involved in this type of transaction, so i steer clear. if my entity is on the contract, I am the one closing. period. 

I can think of several neighborhoods that continued to go up through the crash 6-8 years ago.

Then, the market crashes and rents go down 80% due to some varying factors...none of which you really had control over.  

Stupid investing is accelerating us toward the next crash.

I've been watching HGTV at home, I've also watched The big short (a movie about the 2008 house market crash), and also got an few books that I haven't gotten a chance to read yet.

If you look through BP threads of "omg when is the crash going to happen" it's overwhelmingly people who haven't done a single deal yet.So unless you have some systemic economic collapse of multiple systems and industries, market cycles aren't a big deal.

If you were investing at the time...- Were you investing right up to the crash?

I flipped a couple houses with my dad a few years back (right in the middle of the crash) we did ok on the first one but didn't make money in the second.
