46 THE WARREN Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Hounslow local authority area over time, sourced from the HPI. The four 46 THE WARREN sales between April 2003 and September 2017 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 February 2006 sale was for 2% above the HPI. So the extrapolation line tracks at 2% above the HPI over time, until the September 2017 sale, where it rises to 7% above the HPI. The line then continues to track at 7% above the HPI.

What might 46 THE WARREN be worth now?

46 THE WARREN might now be worth an estimated £734,923.

This is based on house price inflation of 22.5%, between September 2017 and February 2025, for semi-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 22.5% inflationary increase is applied to the most recent sale price for 46 THE WARREN of £600,000 on 21st September 2017. For the value to have increased from £600,000 to £734,923 over the eight years and seven months to February 2025, the following assumptions must hold true:

• The value of 46 THE WARREN has moved in line with the HPI for semi-detached houses in the Hounslow local authority area.
• The September 2017 sale price of £600,000 represented a fair market value for the property.
• The size, condition, and specification of 46 THE WARREN has not materially changed since September 2017.
