While some real estate professionals believe open houses are more trouble than they are worth, others consider them highly valuable in that they generate interest in a property and introduce agents to prospective clients. “It gets a lot of traffic, and we’re for anything to shake the bushes and generate some business,” says REALTOR Robby Young of Mobile, Ala.-based Coldwell Banker United Realtors. Most open houses are held on Sundays, but some agents are opening the doors on weekday nights to meet the needs of potential buyers who work on weekends. Approximately 48 percent of buyers visited open houses as part of their home search in 2008, according to the National Association of Realtors, with newer listings, reasonably priced dwellings and easily accessible properties generating the most traffic.
