18 MERLIN GROVE 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 18 MERLIN GROVE sales from November 1999 and September 2001 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 November 1999 sale was for 10% below the HPI. So the extrapolation line tracks at 10% below the HPI over time, until the September 2001 sale, where it falls to 16% below the HPI. The line then continues to track at 16% below the HPI.

What might 18 MERLIN GROVE be worth now?

18 MERLIN GROVE might now be worth an estimated £398,040.

This is based on house price inflation of 176.4%, between September 2001 and February 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 176.4% inflationary increase is applied to the most recent sale price for 18 MERLIN GROVE of £144,000 on 14th September 2001. For the value to have increased from £144,000 to £398,040 over the 24 years and seven months to February 2025, the following assumptions must hold true:

• The September 2001 sale price of £144,000 represented a fair market value for the property.
