Broker not showing my home to buyers unless I sign an agreement

[Joseph Escamilla]

Hey everyone - I currently have my primary home listed FSBO. I had 2 open houses this weekend, got a ton of interest and even a full price offer.

Of course I keep getting calls from Agents telling me they "have buyers interested in my property", but when they show up to look at the house it just ends up being them trying to pitch me to let them list my house. It is what it is - annoying but of course I have to respect the hustle. 

One Broker in particular is telling me that they have preapproved buyers and that I can remain a FSBO as long as I sign an agreement with them stating their buyer will pay them a separate commission and I pay them nothing.

This seems sketchy to me since I am already offering 2% buyer's agent fee. If you have buyers why wouldn't you just bring them to my property and try to get the 2% commission? Their response to that is "Oh well because then my buyer may go to you directly behind my back" . In my eyes that has nothing to do with me that has to do with your agreement with your buyer - I have had plenty of agents show up with their buyers and make offers.

The strangest thing is I lookup this guy's reviews and they are mostly positive! So I'm wondering if this is really too good to be true or if I am missing out on a decent deal? 

For reference I have attached their flyer they sent me.
