21 THE AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The three 21 THE AVENUE sales between November 2000 and September 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 March 2002 sale was for 33% above the HPI. So the extrapolation line tracks at 33% above the HPI over time, until the September 2019 sale, where it falls to 18% above the HPI. The line then continues to track at 18% above the HPI.

What might 21 THE AVENUE be worth now?

This is based on house price inflation of 21.7%, between September 2019 and March 2025, for detached houses, in the West Northamptonshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 21.7% inflationary increase is applied to the most recent sale price for 21 THE AVENUE of £460,000 on 19th September 2019. For the value to have increased from £460,000 to £559,980 over the six years and six months to March 2025, the following assumptions must hold true:

• The value of 21 THE AVENUE has moved in line with the HPI for detached houses in the West Northamptonshire local authority area.
• The September 2019 sale price of £460,000 represented a fair market value for the property.
