Home price appreciation is an important topic in today’s economy. Using data from the American Community Survey (ACS), we can analyze the gains and losses of property values over time. I estimated the median property values by state in 2017 using the FHFA index and the median property values from the (ACS). I then calculated the growth rate from 2005 -2017. 
The states with the highest estimated median property values in 2017 are Hawaii ($637,892), District of Columbia ($605,756), California ($522,431), Massachusetts ($396,992), and Colorado ($342,967).
The states with the lowest estimated median property values in 2017 are Alabama ($141,714), Oklahoma ($137,387), Arkansas ($129,902), West Virginia ($122,791) and Mississippi ($118,019).
On a regional level, the estimated price growth appears to be the strongest in the South, West, and Midwest. Price growth is weakest in the Northeast states. Overall, all regions are displaying growth in property values with only a few states showing no growth or loses. Below is a breakdown of the Census four regions by state.
- In the South, which typically leads all regions in sales, Texas led the region with 63 percent estimated price growth from 2005 to 2017. Although Florida experienced strong price growth since 2012, home prices have only increased by 14 percent since 2005 when house prices were still generally at peak levels.
- In the West, the least affordable region, Montana led all states with 71 percent price growth from 2005 to 2017. Despite the strong price growth in California since 2012, prices have only increased by 9 percent since 2005. Nevada shows a negative 5 percent price change over this time.
- In the Midwest where affordability is most favorable, North Dakota led all states with 111 percent price growth from 2005 to 2017. The increase is likely due to the boom in shale oil production up until 2014 when oil prices started collapsing. Illinois, while having the smallest growth in the region had an estimated 7 percent price growth over this time.
- In the Northeast where price growth is typically slow, Pennsylvania lead the region with a 40 percent price growth from 2005 to 2017. Rhode Island was the only state to have a decline of negative 4 percent price change over this time.
 I used the FHFA expanded data set, not seasonally adjusted data.
