The following map depicts the value trends of residential property through an 11 year period from 2007 to 2017. When the recession hit in December 2007, home values throughout much of the county began to decline. The map clearly depicts this change as the red, indicating value increases, slowly fades from 2008 thru 2010. Over this same timeframe, the green, indicating decreases in value, becomes more prevalent. From 2011 thru 2012, property values remain mostly unchanged. The road to recovery begins in 2013 with property values rising, first in the southeastern part of the county and then county wide in 2014 and 2015. In 2016 and 2017, values start to stabilize as a greater number of values remain unchanged.
Appraisal districts are required by law to appraise property at 100 percent of its market value as of January 1. This map follows and illustrates the market trend through the recession. Red specifies increasing values, green indicates decreasing values, and yellow shows no change in value.
This map shows a comparison of the average percent change and the average market value by market area for the previous four years. This includes the changes from 2013 to 2014, 2014 to 2015, 2015 to 2016, and 2016 to 2017.
