If you are asking questions like this, you probably shouln't be wholesaling and tying up properties unless you are working hand-in-hand with a very experienced wholesaler. 

The cash flow can help you quit your W2 or if you start flipping and wholesaling enough to replace that salary, that is a great option as well.

I mainlyplan to flip and hold rentals, but I’ll also be wholesaling whatever deals don’t workfor me or I can’t close on.

Yes, your education, and don't fall for online classes on wholesaling.

But I listened to one podcast where he admitted to earning his living with RE commissions and wholesaling.   

Since I've been wholesaling I've just used forms out of books I've read or templets from random web sites, and i feel like I'm about to transition to buy and holds or even brrrs, so i feel better put together paperwork would be better.

I'm just getting started in the wholesaling and possible flip space. 

For properties that I know will attract many investors, I explain wholesaling to seller at listing, that they are likely to be inundated if they don't limit it, and then have seller state in writing, up front, that I should not send them anything under a certain price or with certain terms like fully assignable.

Also a good idea to search for Facebook pages in your area related to wholesaling and general real estate.

Ultimately our main goal build a portfolio of multiple different types of investment properties, buy and holds, rental properties, and fix/flips; but the wholesaling side of real estate seems like an attractive venture as we are just starting with little capital and it could provide us with a revenue stream to become a cash buyer.
