77A CASSIOBURY AVENUE 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 77A CASSIOBURY AVENUE sales between May 2002 and February 2019 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 July 2006 sale was for 56% below the HPI. So the extrapolation line tracks at 56% below the HPI over time, until the February 2019 sale, which was also at 56% below the HPI.

What might 77A CASSIOBURY AVENUE be worth now?

77A CASSIOBURY AVENUE might now be worth an estimated £423,732.

This is based on house price inflation of 14.5%, between February 2019 and December 2024, 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 14.5% inflationary increase is applied to the most recent sale price for 77A CASSIOBURY AVENUE of £370,000 on 15th February 2019. For the value to have increased from £370,000 to £423,732 over the four years and two months to December 2024, the following assumptions must hold true:

• The value of 77A CASSIOBURY AVENUE has moved in line with the HPI for detached houses in the Hounslow local authority area.
• The February 2019 sale price of £370,000 represented a fair market value for the property.
