The below graph shows the average terraced house price in the Epping Forest local authority area over time, sourced from the HPI. The two 14 ONSLOW GARDENS sales from June 2006 and May 2012 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 June 2006 sale was for 43% above the HPI. So the extrapolation line tracks at 43% above the HPI over time, until the May 2012 sale, where it falls to 34% above the HPI. The line then continues to track at 34% above the HPI.

14 ONSLOW GARDENS might now be worth an estimated £628,926.
This is based on house price inflation of 82.3%, between May 2012 and August 2025, for terraced houses, in the Epping Forest local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
