40 COPTHORNE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Luton local authority area over time, sourced from the HPI. The three 40 COPTHORNE sales between March 2003 and September 2008 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 2004 sale was for 27% above the HPI. So the extrapolation line tracks at 27% above the HPI over time, until the September 2008 sale, where it falls to 16% above the HPI. The line then continues to track at 16% above the HPI.

What might 40 COPTHORNE be worth now?

40 COPTHORNE might now be worth an estimated £546,855.

This is based on house price inflation of 85.4%, between September 2008 and May 2026, for detached houses, in the Luton local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 85.4% inflationary increase is applied to the most recent sale price for 40 COPTHORNE of £294,995 on 5th September 2008. For the value to have increased from £294,995 to £546,855 over the eighteen years and four months to May 2026, the following assumptions must hold true:

• The value of 40 COPTHORNE has moved in line with the HPI for detached houses in the Luton local authority area.
• The September 2008 sale price of £294,995 represented a fair market value for the property.
• The size, condition, and specification of 40 COPTHORNE has not materially changed since September 2008.
