They use a local agent to come to your house to meet with you, give you feedback on the listing, consult on pricing, etc. Basically everything an agent does except take a commission.
Flat-fee based on the level of service you want.... $2,500, $3,000, or $3,500 based upon the level of service you want. Came highly recommended from a friend of mine, so I recently signed up to use, but curious if others have any feedback as well. Especially on the higher end of prices, this pricing compared to a realtor commission is absurd.
