21 SAXON LANE 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 21 SAXON LANE sales from May 2010 and August 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 May 2010 sale was for 23% above the HPI. So the extrapolation line tracks at 23% above the HPI over time, until the August 2019 sale, where it rises to 35% above the HPI. The line then continues to track at 35% above the HPI.

What might 21 SAXON LANE be worth now?

The 20.3% inflationary increase is applied to the most recent sale price for 21 SAXON LANE of £525,000 on 21st August 2019. For the value to have increased from £525,000 to £631,649 over the four years and eight months to December 2024, the following assumptions must hold true:
