In a monthly survey of REALTORS®, respondents reported that properties were typically on the market for 42 days (36 days in October 2018; 40 days in November 2017), according to the November 2018 REALTORS® Confidence Index Survey. Properties are staying longer on the market due to slower demand with mortgage rates rising and with new home construction steadily, though modestly, rising.
During September–November 2018, properties typically stayed on the market for 31 to 45 days in California, Oregon, Arizona and Texas, a slower pace compared to less than one month in previous months (Map 1). However, properties continue to sell in less than 31 days in the District of Columbia (28 days) and in 16 states such as Washington (28 days), Nevada (28 days), Utah (23 days), Colorado (26 days), and Massachusetts (27 days).
Properties typically stayed longer on the market in September-November 2018 compared to the same period in 2017 (blue areas) in the District of Columbia and in 22 states such as California, Washington, Oregon, Nevada, Colorado, Massachusetts, and Texas (Map 2).
Properties are staying longer on the market due to the combination of lower demand and the steady increase in new home construction. In states such as California, Oregon, Colorado, Texas, Virginia, North Carolina, and South Carolina, the number of building permits increased during November 2017-October 2018 compared to the prior 12-month period (Map 3).
 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.
