Whenever I go on a listing appointment, I pull up an Archive search to see the listing history of the property. Whenever a buyer wants to write an offer on a property, I again pull up an archive search on the property. Many times, agents think that if they just relist a house, the listing will refresh itself and gain a lot more activity.
This is true, to an extent. It'll get more lookers, but when they pull up the history, you better be prepared for questions as to why the house hasn't sold yet. Last year, I finally cancelled a listing that had been on the market for a year and a half. We were priced about $20k lower than the builders same floorplan, but couldn't compete with the builder's incentives. Plus, the seller required a 4 hour notice for showings, and she denied 4 out of every 5 showing requests... how does that sell a house?
So, I started getting calls from agents wondering why the house was priced so low and what was wrong with it. Nothing is wrong with it, except the seller won't let people in to see it... we would go in circles.
Make sure you pull up the property history so you know more questions to ask if you see the property has been listed with 3 different agents in a 6 month span... you might not want to work with the seller as it's not always the agent at fault for a house not selling!!
