Wholesalers Holding and Flipping vs. Assigning

[Pat Arneson]

What are some reasons wholesalers either hold and flip vs. assigning out? I have a few wholesalers in my area who flip a ton of houses but also list some that they are willing to assign. My assumption is they avoid the headaches or have too many in their flip queue and would rather assign. Just seems odd why they wouldn't flip them all...
