15 THE KNOWLE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Basildon local authority area over time, sourced from the HPI. The two 15 THE KNOWLE sales from December 2017 and June 2018 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 2017 sale was for 24% below the HPI. So the extrapolation line tracks at 24% below the HPI over time, until the June 2018 sale, where it rises to 16% below the HPI. The line then continues to track at 16% below the HPI.

What might 15 THE KNOWLE be worth now?

The 17.3% inflationary increase is applied to the most recent sale price for 15 THE KNOWLE of £467,500 on 19th June 2018. For the value to have increased from £467,500 to £548,424 over the five years and six months to December 2024, the following assumptions must hold true:
