I don’t understand, why would a brokerage not want to work with a FSBO if the seller is willing to pay them? Or even better for realtor to be dual and I pay them a larger commission?

In my case the potential buyer found my listing, contacted me directly, and came alone to view the house, liked it, and wanted to pursue it. We had a discussion where I disclosed that I would indeed cooperate with a realtor and pay the commission, if that is what they the buyer felt more comfortable with. Being me, I informed them up front of the cost of typical commission say 5% would be ~$22,000. I told them if they chose to go direct to an attorney I would split that difference with them and we would both benefit. They felt more comfortable using a realtor, who IF I agree to a 2.5% commission stands to make $11,000….. For what? I can use a real estate attorney to review the offer and help me counter, process all the paperwork, and it will cost me, assuming no issues come up, ~$1000, that is a difference of $10,000!

Of course they may never make an offer and I will list traditionally in the spring and humbly admit I was wrong and there is much more to selling my home than I acknowledged today.
