If your house sits on the market for a few months, chances are, in a slow real estate market, it will sell for less than it would have when you first listed it.
A good real estate agent will be forthright about this fact in the beginning.
"If they demoralize you, it's a good sign," says Alan Sims, a forensic real estate appraiser and chief executive of the Center for Litigation and Consumer Real Estate Education. "If [the home] lingers on the market longer than three months, the owner needs a new analysis." Your agent should talk to you up front and throughout the sale process about where the market is and what you can do to help your home sell.
