If you could get a COMPLETE list of the actives, pendings and recent solds in your zip area you could probably get a pretty good idea on what listing price would result in a sale.
If it were me, I’d look to see which agents’ names came up most often among the closed sales and get their opinions, if not retain them outright. Your odds usually improve when you retain and listen to a proven winner.
As an appraiser, the only time I accept assignments that involve recommending listing prices is when the property is unusual enough that the realty agents are referring their clients to me. For most properties it usually goes the other way; I usually refer these people to the active realty agents.
Appraisers generally look to see what the property value would “probably” be like as of a transaction closing today. A good realty agent looks forward a bit in anticipation of a closed sale in the near future. There is a distinction between the two and for that reason I’m not a big advocate of retaining appraisers to suggest listing prices under most circumstances. Appraisers are observers of market participants, they don’t actually participate themselves.
