The below graph shows the average detached house price in the Bexley local authority area over time, sourced from the HPI. The two 21 ROWANWOOD AVENUE sales from February 2000 and April 2014 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 February 2000 sale was for 91% above the HPI. So the extrapolation line tracks at 91% above the HPI over time, until the April 2014 sale, where it falls to 80% above the HPI. The line then continues to track at 80% above the HPI.
21 ROWANWOOD AVENUE might now be worth an estimated £1,267,931.
