This is a great deal if I can get it under contract but I'm not sure how that would work being that the owner has a realtor and also how could the realtor's commission affect the deal?

The harsh reality is, the listing agent isn't going to jump through a bunch of hoops for you if you are going to bring a buyer's agent in later in the process to collect half of the commission. 

Seller typically pays the buyer broker commission when you purchase a NNN property.

My time is valuable so making 10k for mentor ship or  consultant on a deal doesn't make sense  when my commission is generally six figures per deal.The main question is how much money do you have to invest?

@Dave Foster Yes you would still be wholesaling since you would be making the spread on the deal versus the standard 3% realtor commission but aside from that I agree with you.

Keep in mind that when you sell, you're going to spend a chunk of that equity in sales commissions, title insurance, termite clearance, and other little repairs that the buyer wants.
