“If over the last three to six months the average days on market has been increasing, it typically means that things are priced too high and a correction will need to help,” said Holden Andrews, founder of Helpful Home Group. “This metric is tied to days on market, because the longer the property is on the market, the more price reductions the property will have,” said Casey TeVault, Realtor and founder of Casey Buys Houses. When home prices drop due to foreclosures or short sales, this can drive down all prices in the area.
