PENINNIS 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 PENINNIS sales from October 2015 and January 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 October 2015 sale was for 19% below the HPI. So the extrapolation line tracks at 19% below the HPI over time, until the January 2018 sale, where it rises to 11% below the HPI. The line then continues to track at 11% below the HPI.

What might PENINNIS be worth now?

PENINNIS might now be worth an estimated £388,412.

This is based on house price inflation of 31.7%, between January 2018 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 31.7% inflationary increase is applied to the most recent sale price for PENINNIS of £295,000 on 24th January 2018. For the value to have increased from £295,000 to £388,412 over the six years and eleven months to February 2025, the following assumptions must hold true:

• The value of PENINNIS has moved in line with the HPI for detached houses in the Cornwall local authority area.
• The January 2018 sale price of £295,000 represented a fair market value for the property.
• The size, condition, and specification of PENINNIS has not materially changed since January 2018.
