Should we invest in a service?

[Corey Birger]

We have come across a few different opportunities from the "the latest softwares and tricks" to franchise offers.  I am wondering if we need to get involved with them or just sit on our money and work things on our own. We have experience in different areas of real estate and construction but we are starting new in wholesaling, so we would love to get your insight. 

We are looking into:

Connected Investors

Real Alliance

Flipping Formula

Again, all comments, suggestions and advice are welcome.
