As much as you defend yourself; PRICE is 98% of the problem, 98% of the time.
Have your Agent do a new CMA.
If you are in a good urban area, you should be able to find a lot of good comps; use a lot, and narrow it down to LIKE houses.
How is the Curb Appeal?
How is the neighborhood?
How has the weather been?
Has anything been happening to distract the would-be buyers?
Have you eliminated the CLUTTER?
Have you removed the PERSONAL items like family pictures?
Does the house SMELL? Ask a stranger; you may not sense your familiar smells.
Consider the PRICE again; you should be UNDER the Comp's to attract multiple offers!
Good luck and may God bless
