The below graph shows the average detached house price in the Winchester local authority area over time, sourced from the HPI. The five 17 KNOWLE AVENUE sales between June 2002 and February 2019 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 18% below the HPI. So the extrapolation line tracks at 18% below the HPI over time, until the February 2019 sale, where it rises to 14% below the HPI. The line then continues to track at 14% below the HPI.
17 KNOWLE AVENUE might now be worth an estimated £661,507.
