Rutherford County as a whole has seen slower numbers; so part of it is market. HOWEVER, usually low showings are caused by one or more of the following issues:
1. Not properly listed for agents to find. May be in an incorrect area or may not be mapping correctly.
2. Photos are either not present or the photos are poorly shot; or if the photos are good, the home wasn't properly staged for photography.
3. The home may have a poor overall internet presence. 84% of all homebuyers use the internet for their part of their home search process according to 2007 NAR statistics.
4. The MAJOR reason is that it could be priced in a range where there's either a lot of competition or its overpriced for the location and condition.
Ultimately, if you want more "traffic," there are tons of bogus things you/an agent can do to get people through the door. However, if you want quality traffic that attracts the RIGHT buyer, make sure you know your market absorption rates and price competition.
