The below graph shows the average terraced house price in the North Northamptonshire local authority area over time, sourced from the HPI. The three 25 HILLSIDE AVENUE sales between May 1998 and February 2004 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 2002 sale was for 23% above the HPI. So the extrapolation line tracks at 23% above the HPI over time, until the February 2004 sale, where it falls to 12% above the HPI. The line then continues to track at 12% above the HPI.

25 HILLSIDE AVENUE might now be worth an estimated £228,312.
This is based on house price inflation of 141.6%, between February 2004 and May 2026, for terraced houses, in the North Northamptonshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 141.6% inflationary increase is applied to the most recent sale price for 25 HILLSIDE AVENUE of £94,500 on 18th February 2004. For the value to have increased from £94,500 to £228,312 over the 21 years and nine months to May 2026, the following assumptions must hold true:
