SUNNYSIDE 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 four SUNNYSIDE sales between May 1998 and November 2023 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 April 2014 sale was for 5% below the HPI. So the extrapolation line tracks at 5% below the HPI over time, until the November 2023 sale, where it rises to 8% above the HPI. The line then continues to track at 8% above the HPI.

What might SUNNYSIDE be worth now?

SUNNYSIDE might now be worth an estimated £459,033.

This is based on house price deflation of 5.4%, between November 2023 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 5.4% deflationary decrease is applied to the most recent sale price for SUNNYSIDE of £485,000 on 24th November 2023. For the value to have decreased from £485,000 to £459,033 over the three years and seven months to April 2026, the following assumptions must hold true:

• The value of SUNNYSIDE has moved in line with the HPI for detached houses in the Cornwall local authority area.
• The November 2023 sale price of £485,000 represented a fair market value for the property.
• The size, condition, and specification of SUNNYSIDE has not materially changed since November 2023.
