12 HILLSIDE 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 12 HILLSIDE sales between September 2000 and January 2009 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 September 2001 sale was for 20% below the HPI. So the extrapolation line tracks at 20% below the HPI over time, until the January 2009 sale, where it falls to 33% below the HPI. The line then continues to track at 33% below the HPI.

What might 12 HILLSIDE be worth now?

12 HILLSIDE might now be worth an estimated £315,460.

This is based on house price inflation of 83.4%, between January 2009 and December 2024, 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 83.4% inflationary increase is applied to the most recent sale price for 12 HILLSIDE of £172,000 on 16th January 2009. For the value to have increased from £172,000 to £315,460 over the fourteen years and one month to December 2024, the following assumptions must hold true:

• The value of 12 HILLSIDE has moved in line with the HPI for detached houses in the West Northamptonshire local authority area.
• The January 2009 sale price of £172,000 represented a fair market value for the property.
• The size, condition, and specification of 12 HILLSIDE has not materially changed since January 2009.
