The below graph shows the average detached house price in the Hounslow local authority area over time, sourced from the HPI. The two 28 OSTERLEY ROAD sales from December 1996 and February 2008 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 December 1996 sale was for 31% above the HPI. So the extrapolation line tracks at 31% above the HPI over time, until the February 2008 sale, which was also at 31% above the HPI.

What might 28 OSTERLEY ROAD be worth now?
