Avoiding the broker agency commissions

[Sri A.]

Hello there!! I'm just finishing rehabbing a property that I bought 6 months ago. I'm looking to sell this property soon but I really don't want to pay big chuck of commission to broker agents. So firstly, I wanna try put it "For Sale by Owner" but I haven't done this before so looking for some guidance, do's and don'ts etc. How to pull market report/comps (I already looked at comparables in zillow) and how to come up with right listing price cause I don't see many CMA's for fully rehabbed houses around lately?

I know zillow, trulia, realtytrac but are there any other websites that I can list it "For Sale by Owner" that can make this property visible to more buyers?

Secondly, if I choose to go with realtor then can I negotiate with agency on the commission percentage? If so how much is reasonable to ask? Are there any guidelines or better way of approaching this situation?

Truly appreciate your thoughts and suggestions.

Thanks
