Flat fee broker or traditional agent for a flip?

[Brent Tomczak]

Hello,

I'm preparing to list my first flip, and I'm debating how I should go about this. When I was about 98% done w/ the rehab, I put a sign out front just to see if I get lucky, no real serious offers. There is no doubt this house will sell within first month, if it is on the MLS, on all the real estate apps, and priced right. I'm just trying to maximize my profit, but perhaps I'm being greedy. I really do not want to give someone 5-6% for all of my hard work.

I was strongly considering going with a flat fee broker to save $7-8000, and just handle the buyer agents.  I was hoping to get some advice whether this could be a strong way to go, pros and cons. 

How much more marketing can an agent do besides listing on MLS, and the real estate apps? Is it WORTH it, or is a flat fee broker a solid way to go?

Thanks!
