THORNDON 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 THORNDON sales from November 2016 and September 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 November 2016 sale was for 14% above the HPI. So the extrapolation line tracks at 14% above the HPI over time, until the September 2018 sale, where it rises to 48% above the HPI. The line then continues to track at 48% above the HPI.

What might THORNDON be worth now?

THORNDON might now be worth an estimated £655,302.

This is based on house price inflation of 30.3%, between September 2018 and December 2024, 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 30.3% inflationary increase is applied to the most recent sale price for THORNDON of £503,000 on 11th September 2018. For the value to have increased from £503,000 to £655,302 over the five years and nine months to December 2024, the following assumptions must hold true:

• The value of THORNDON has moved in line with the HPI for detached houses in the Cornwall local authority area.
• The September 2018 sale price of £503,000 represented a fair market value for the property.
• The size, condition, and specification of THORNDON has not materially changed since September 2018.
