Amid strong demand and tight supply, REALTORS® reported that properties that sold in May–July 2017 were typically on the market for less than 31 days in 29 states and in the District of Columbia, according to the July 2017 REALTORS® Confidence Index Survey. Properties sold quickly in states such as Washington (20 days), Colorado and Kansas (21 days), and California (22 days). Only in seven states did properties typically stay on the market for two months or more: Wyoming, Louisiana, Mississippi, Alabama, West Virginia, Vermont, and Connecticut.
Nationally, properties typically stayed on the market for 30 days in July 2017 days (28 days in June 2017; 36 days in July 2016). For comparison, properties were typically on the market for 97 days in 2011.
 In generating the median days on market at the state level, NAR uses data for the last three surveys to have close to 30 observations. Small states such as AK, ND, SD, MT, VT, WY, WV, DE, and D.C., may have fewer than 30 observations.
The survey asks, “For the last house that you closed in the past month, how long was it on the market from listing time to the time the seller accepted the buyer’s offer?” The median is the number of days at which half of the properties stayed on the market.
 Days on market usually refers to the time from listing date to contract date.
