The below graph shows the average terraced house price in the Three Rivers local authority area over time, sourced from the HPI. The two 148 PENROSE AVENUE sales from November 2012 and June 2021 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 November 2012 sale was for 22% above the HPI. So the extrapolation line tracks at 22% above the HPI over time, until the June 2021 sale, where it rises to 37% above the HPI. The line then continues to track at 37% above the HPI.

148 PENROSE AVENUE might now be worth an estimated £637,241.
This is based on house price inflation of 10.8%, between June 2021 and October 2025, for terraced houses, in the Three Rivers local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
