The below graph shows the average detached house price in the Barnsley local authority area over time, sourced from the HPI. The five 19 MORTIMER HEIGHTS sales between November 2000 and March 2025 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the October 2017 sale was for 21% above the HPI. So the extrapolation line tracks at 21% above the HPI over time, until the March 2025 sale, where it rises to 32% above the HPI. The line then continues to track at 32% above the HPI.

19 MORTIMER HEIGHTS might now be worth an estimated £346,716.
