ROSIE 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 three ROSIE sales between August 1997 and October 2022 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 February 2002 sale was for 8% below the HPI. So the extrapolation line tracks at 8% below the HPI over time, until the October 2022 sale, where it rises to 4% below the HPI. The line then continues to track at 4% below the HPI.

What might ROSIE be worth now?

ROSIE might now be worth an estimated £425,973.

This is based on house price deflation of 4.3%, between October 2022 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 4.3% deflationary decrease is applied to the most recent sale price for ROSIE of £445,000 on 7th October 2022. For the value to have decreased from £445,000 to £425,973 over the one year and ten months to December 2024, the following assumptions must hold true:

• The value of ROSIE has moved in line with the HPI for detached houses in the Cornwall local authority area.
• The October 2022 sale price of £445,000 represented a fair market value for the property.
• The size, condition, and specification of ROSIE has not materially changed since October 2022.
