This week we review changes in property market values and tax base for 25 cities in Dallas County since 2007. This builds on the analysis throughout the last month focusing on the property tax and its importance to local cities. Last week we looked at the structure of the tax base in our 25 cities on the eve of the Great Recession in 2007. Since then, there has been substantial change in the local economy.
Total Taxable Value
Our 25 cities saw their combined tax bases grow by 30 percent between 2007 and 2016. The average change for these cities was 45 percent and the median change was 27 percent. The largest and smallest changes were 308 percent and 3 percent, respectively.
Residential and Commercial Changes
Because of some changes in reporting over the period, it is difficult to calculate an accurate change in tax base by commercial and residential categories. Instead, we can present the changes in market value for these categories.
The combined residential market values for the 25 cities grew 29 percent from 2007 to 2016. The average of the individual city changes was 24 percent and the median of the city changes was 27 percent. There was considerable variation across the cities, with the largest increase being 143 percent and a decline of 8 percent on the other end of the scale. The changes for the 25 cities in shown in Figure 1.
On the commercial side, the total change for all 25 cities combined was 43 percent. The average of the city changes was 76 percent and the median was 43 percent. There was a very wide range of growth rates across the cities. The largest increase was 533 percent and the smallest increase was 16 percent. The change in commercial market value is shown in Figure 2.
Change in Commercial Share of Market Value
Between 2007 and 2016, most cities saw the share of total market value in commercial property increase. That is, commercial property grew in importance compared to residential property. The average change for the 25 cities was a 5-percentage point increase in the share held by commercial property. The median increase was 3-percentage points. The largest shift was a 26-percentage point increase in commercial property’s share of total market value. The largest decrease in share of commercial property was 1 percentage point. The change in the share of property values in commercial property are shown in Figure 3.
