Hi Christopher. yes, if you hire your realtor they will have to split the commission. true, everything is negotiable. As for the %, it really depends on the scope of work to be rendered, and more importantly, the quality of the service and the overall process experience. You may always hire another realtor to represent your interest if you think there is at the very least risk of compromising a fair outcome. also, at the end of the day, we do business with people who we like. Hope it turns out well for you!
