NETHERHILL 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 NETHERHILL sales from December 2008 and October 2025 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 2008 sale was for 4% above the HPI. So the extrapolation line tracks at 4% above the HPI over time, until the October 2025 sale, where it rises to 30% above the HPI. The line then continues to track at 30% above the HPI.

What might NETHERHILL be worth now?

NETHERHILL might now be worth an estimated £551,233.

This is based on house price deflation of 2%, between October 2025 and April 2026, 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 2% deflationary decrease is applied to the most recent sale price for NETHERHILL of £562,250 on 24th October 2025. For the value to have decreased from £562,250 to £551,233 over the one year and six months to April 2026, the following assumptions must hold true:

• The value of NETHERHILL has moved in line with the HPI for detached houses in the Cornwall local authority area.
• The October 2025 sale price of £562,250 represented a fair market value for the property.
• The size, condition, and specification of NETHERHILL has not materially changed since October 2025.
