During the crash there was an abundance of unwanted properties.

Aka a crash in the markets.

As far as timing, I don't see a crash or correction coming anytime soon to DFW so you may just have to suck it up and know you won't get the deals you would have a year or two ago.  

Since the housing market crashed, the owner foreclosed. 2)- I bought for %60 less than the foreclosure price.

We were founded at the height of the market crash and specialize in off market, discounted properties.

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.
