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 2018 using the FHFA index and the median property values from the (ACS). I then calculated the growth rate from 2005 -2018. 
The states with the highest estimated median property values in 2018 are The District of Columbia ($677,473), Hawaii ($649,272), California ($566,311), Massachusetts ($428,161) and Washington ($384,740).
The states with the lowest estimated median property values in 2018 are Alabama ($148,827), Oklahoma ($139,385), Arkansas ($135,733), Mississippi ($123,586) and West Virginia ($120,720).
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 strong to moderate growth in property values. Below is a breakdown of the Census four regions by state.
- 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.
 I used the FHFA expanded data set not seasonally adjusted data.
