15 CASWELL CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the North Northamptonshire local authority area over time, sourced from the HPI. The three 15 CASWELL CLOSE sales between June 2008 and March 2021 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 December 2013 sale was for 18% above the HPI. So the extrapolation line tracks at 18% above the HPI over time, until the March 2021 sale, where it falls to 5% below the HPI. The line then continues to track at 5% below the HPI.

What might 15 CASWELL CLOSE be worth now?

The 17.7% inflationary increase is applied to the most recent sale price for 15 CASWELL CLOSE of £328,000 on 29th March 2021. For the value to have increased from £328,000 to £385,955 over the four years and one month to February 2025, the following assumptions must hold true:
