The below graph shows the average semi-detached house price in the Harrow local authority area over time, sourced from the HPI. The two 18 THE GREENWAY sales from January 1995 and May 1997 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 1995 sale was for 4% below the HPI. So the extrapolation line tracks at 4% below the HPI over time, until the May 1997 sale, where it rises to 2% above the HPI. The line then continues to track at 2% above the HPI.
18 THE GREENWAY might now be worth an estimated £697,372.
This is based on house price inflation of 509.1%, between May 1997 and June 2025, for semi-detached houses, in the Harrow local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 509.1% inflationary increase is applied to the most recent sale price for 18 THE GREENWAY of £114,500 on 9th May 1997. For the value to have increased from £114,500 to £697,372 over the 27 years and eleven months to June 2025, the following assumptions must hold true:
