They will try and sell it quick as possible as opposed to get the most bang for your buck so you must be stern with the sale price
As a realtor, in my market there hasn't been a better time for a home buyer to puff their chest out and price their home above fair market value based on local comps within the last 120 days since 2007.
Unless, you have a cash buyer, you can only sell your home for the amount a bank is willing to loan a buyer, as most buyers get a mortgage, especially at sub 4% mney.
Interview a few agents, ask them to show you the comps from the last 120 days in your neighborhood/local area. The one that impresses you the most and you feel most comfortable with is te ne i would move forward with.
