Your comment reads as you don’t need a realtor as a buyer — and I agree to an extent. I always thought that the service was provided for the seller

Things our agent did I would not have done or not done properly on top of the paperwork and legal advice:

- got us in touch with home stylist and a photographer who were great

- had a phone book of prospective customers looking for a place like ours

- followed up with people who were interested and arranged a second showing

About the commissions, either it is very regional or we were lucky but we agreed on a flat fee plus some percent if and only if the price goes above some target.
