21 MARCONI CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Cornwall local authority area over time, sourced from the HPI. The two 21 MARCONI CLOSE sales from November 1999 and January 2016 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 1999 sale was for 19% above the HPI. So the extrapolation line tracks at 19% above the HPI over time, until the January 2016 sale, where it falls to 8% below the HPI. The line then continues to track at 8% below the HPI.

What might 21 MARCONI CLOSE be worth now?

This is based on house price inflation of 41.7%, between January 2016 and February 2025, for detached houses, in the Cornwall local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 41.7% inflationary increase is applied to the most recent sale price for 21 MARCONI CLOSE of £284,000 on 5th January 2016. For the value to have increased from £284,000 to £402,535 over the eight years and eleven months to February 2025, the following assumptions must hold true:

• The value of 21 MARCONI CLOSE has moved in line with the HPI for detached houses in the Cornwall local authority area.
• The January 2016 sale price of £284,000 represented a fair market value for the property.
