Average Days On Market is about 100. However, your profile says you are a home seller.
If you are selling your home with a REALTOR, ask them to provide you with the number of homes like yours that, since your property hit the market, have:
Come onto the market
reduced their price
The truth is that home that sell first usually sell for closest to asking price. The longer a home sits, the greater the gap. In your area, that means if the homes sell in a month, they average about 98% of asking. At 120 DOM that drops to about 93%. With home values declining about 1% per month, there is no value in pricing a home above market value.
The best way to get market value is to UNDER PRICE the home and start a bidding contest.
