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.

- In the South, which typically leads all regions in sales, The District of Columbia led the region with 76 percent estimated price growth from 2005 to 2018. Maryland experienced 1 percent annual price growth and since 2005, home prices have grown 21 percent.
- In the West, the least affordable region, Montana led all states with 88 percent price growth from 2005 to 2018. Despite the strong price growth in California since 2012, prices have only increased by 19 percent since 2005. Nevada shows a 9 percent price change over this time turning around any previous loss in value.
- In the Midwest where affordability is most favorable, North Dakota led all states with 115 percent price growth from 2005 to 2018. Illinois, while having the smallest growth in the region had an estimated 12 percent price growth over this time.
- In the Northeast where sales and price growth is typically slow, Pennsylvania lead the region with a 48 percent price growth from 2005 to 2018. Rhode Island, while having the smallest gain of all states, increased 6 percent price change over this time. Rhode Island is one of two states that turned around a negative property value over this time compared to 2017.

In the monthly REALTORS® Confidence Index Survey, the National Association of REALTORS® asks members “In the neighborhood or area where you make most of your sales, what are your expectations for residential property prices over the next year?”
Among the REALTOR® respondents who responded to the January 2018 survey, the median expected price change for the next 12 months was 3.6 percent, according to the January 2018 REALTORS® Confidence Index Survey. In December 2017, the median expected price change was 3.1 percent. Strong buyer traffic amid low supply of homes coming into the market continues to push up home prices. In January 2018, the median price of existing homes sold rose to $240,500, up six percent from one year ago.
The map below shows the median expected price change of the respondents in the next 12 months at the state level based on surveys conducted during November 2017—January 2018. The highest median expected price growth of more than five to seven percent was in Washington, Nevada, and Wyoming.
In Oregon, Idaho, Utah, Arizona, Colorado, and Florida, the median expected price growth was four to five percent. REALTORS® reported stronger buyer traffic in these states compared to one year ago, based on the RCI Buyer Traffic Index, while the number of homes for sale has remained essentially unchanged, based on the RCI Seller Traffic Index.
In states with high property tax rates or property prices, such as New York, New Jersey, Connecticut, and California—states which are the most affected by the Tax Cuts and Jobs Act that put a cap on total itemized deductions property and state and local taxes — the median expected price change among respondents was two to three percent.
Lack of supply amid strong buyer interest continues to push prices up. At the metro area level, data on the number of active listings on Realtor.com indicates how serious the lack of supply is. Of the 500 metro areas tracked by Realtor.com, active listings are lower compared to one year ago in 395 out of 500 metro/micro areas, 80 percent. Areas in red show active listings are lower compared to one year ago, while areas in blue have more active listings.
 To increase the number of observations for each state, NAR uses data from the last three surveys.
 To note, the median expected price change is based on data collected from October—December 2017, while the Trump administration released its proposed tax measures only in November 2017, and the Tax Cuts and Jobs Act was signed by President Trump on December 22, 2017, so October survey responses may not factor in the effect of tax reform measures on price expectations.
In a monthly survey of REALTORS®, respondents are asked “Compared to the same month last year, how would you rate the past month’s traffic in neighborhood(s) or area(s) where you make most of your sales?” Respondents rate buyer traffic as “Stronger” (100), “Stable” (50), or “Weaker” (0) and the responses are compiled into a diffusion index. An index greater than 50 means that more respondents reported “stronger” than “weaker” conditions.
The chart below shows buyer traffic conditions in October–December 2017 compared to conditions one year ago, according to the December 2017 REALTORS® Confidence Index Survey. Except for four states, REALTORS® reported that buyer conditions were “stable” (unchanged) to “very strong” compared to conditions one year ago. Respondents from Texas and Florida, states which were hit by hurricanes Harvey and Irma, generally reported “strong” buying activity compared to one year ago. On the other hand, Alaska, North Dakota, Louisiana, and West Virginia respondents generally reported “weak” buyer traffic compared to one year ago, and this may be related to the effect of the slump in oil prices since 2015, though oil prices have started to firm up again in 2017 as OPEC cut its oil production.
Supply conditions in October –December 2017 is improving but supply is still tight, with only 26 states having seller traffic conditions that are “stable” (unchanged) or “strong” compared to conditions one year ago. Most of the states with stable or improving seller activity in October-December 2017 are in southern area of the United States.
Nationally, the REALTORS® Buyer Traffic Index registered at 66, while the REALTORS® Seller Traffic Index was at 47. An index above 50 indicates that more respondents reported stronger than weaker conditions compared to one year ago, so the data indicates that homebuying demand continues to outpace supply.
The REALTORS® Buyer Traffic Index as Leading Indicator of Contracts and Sales
The REALTORS® Buyer Traffic Index is a leading indicator of future contracts (pending home sales sales) and closings (existing home sales). The REALTORS® Buyer Traffic Index tends to lead pending home sales by one month and existing home sales by two months. The uptick in the November and December 2017 Buyer Traffic Index indicates a continued uptick in sales on a month-to-month basis in January and February 2018.
 In generating the indices, 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. For graphical purposes, index values from 25.01 to 45 are labeled “Weak,” values of 45.01 to 55 are labeled “Stable,” values of 55.01 to 75 are labeled “Strong,” and values greater than 75 are labeled “Very Strong.”
