Neha15, Of the answers below Keri Ricci did best IMHO. Your question is ambiguous to some extent. Some look at the buyer's agent at the one who 'sold' the home - as opposed to the seller's agent that listed it. Keri's answer applied to listing agents. Since I'm an EXCLUSIVE BUYER AGENT I don't list. However, I do refer seller's (often my prior buyer clients) to listing agents. Before I do that - I research. I can obtain all the info on the agents in most South Jersey counties, including ratio of listings to sold and list price to sales price ratios and more by city, county, zip code and any other way the mls can be searched.
Anyone looking for a listing agent needs to know more than their marketing plan. They need to know their history - all of it.
By the way, as a buyer's agent - I research the seller's agent's history too. You have to know your opponent - without getting on their bad side preferably.
