Buyer, Consult a Real Estate Pro like me to look out for your interests. Why would any buyer try and do what we do everyday?? We don't cost the buyer a penny.
But, again negotiate to suit your needs. Good Luck to you.
(1) It's all negotiable.
(2) Often, the buyer and seller try to pattern the fees after what's the norm in their area. And those norms or customs can vary.
If you're the buyer, hopefully you have a Realtor who can inform you about what's typical in your area, and then help you negotiate so you get at least that and perhaps more.
Hope that helps.
Of course, I am assuming you are using a Buyer's Agent. If you don't have one I am sure your loan officer can refer you to a good one!
Of course the topic of FSBO can be dicey.....that's why so many FSBOs eventually turn to a Realtor.
