21 OSTERLEY CRESCENT Price Paid vs. HPI Average

The below graph shows the average detached house price in the Hounslow local authority area over time, sourced from the HPI. The three 21 OSTERLEY CRESCENT sales between May 2002 and September 2007 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 January 2004 sale was for 21% below the HPI. So the extrapolation line tracks at 21% below the HPI over time, until the September 2007 sale, where it falls to 27% below the HPI. The line then continues to track at 27% below the HPI.

What might 21 OSTERLEY CRESCENT be worth now?

This is based on house price inflation of 81.1%, between September 2007 and February 2025, for detached houses, in the Hounslow local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 81.1% inflationary increase is applied to the most recent sale price for 21 OSTERLEY CRESCENT of £407,500 on 18th September 2007. For the value to have increased from £407,500 to £737,801 over the eighteen years and seven months to February 2025, the following assumptions must hold true:
