This is one of my favorite features of Bigger Pockets especially for asking specific questions.

Depends on your source of funds.  

You could also use the source you mentioned; especially Craig's list.                             

With a few limited add-ins/subtractions for additional features like garage/deck...though, added nothing for my solar panels (whatever!). 

Agree that you should look at how stable the income source is (type, length, etc.).  

Split was not that good 60/40, but in order to have the foundations to build a good business, it was fine for me.Then, I move to a pops and mom, you know them there are tons of them out there, where the split is great, ( you get almost 100% commission), but marketing and support for you is none, I was doing my CE on my board and trying to get as much as I could from different sources, at that time, my income plateau, and then I realized in order for me to grow, I had to move.

I am thinking loud and please hear :I have contractors rehabbers and landlords on my buyers list , I also have access to good deals right on MLS and other sources . 

I use wholesalers, direct sale by owner, and MLS as sources.  

This would be a great feature though and I'm sure it will be around in the near future!
