JOLIEBON 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 two JOLIEBON sales from February 2018 and March 2025 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 2018 sale was for 14% below the HPI. So the extrapolation line tracks at 14% below the HPI over time, until the March 2025 sale, where it rises to 9% below the HPI. The line then continues to track at 9% below the HPI.

What might JOLIEBON be worth now?

JOLIEBON might now be worth an estimated £430,703.

This is based on house price inflation of 0.6%, between March 2025 and June 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 0.6% inflationary increase is applied to the most recent sale price for JOLIEBON of £428,000 on 31st March 2025. For the value to have increased from £428,000 to £430,703 over the nine months to June 2025, the following assumptions must hold true:

• The value of JOLIEBON has moved in line with the HPI for detached houses in the West Northamptonshire local authority area.
• The March 2025 sale price of £428,000 represented a fair market value for the property.
• The size, condition, and specification of JOLIEBON has not materially changed since March 2025.
