ROSEVEAN 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 ROSEVEAN sales between June 2004 and October 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 May 2012 sale was for 122% above the HPI. So the extrapolation line tracks at 122% above the HPI over time, until the October 2018 sale, where it rises to 136% above the HPI. The line then continues to track at 136% above the HPI.

What might ROSEVEAN be worth now?

ROSEVEAN might now be worth an estimated £1,030,396.

This is based on house price inflation of 28%, between October 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 28% inflationary increase is applied to the most recent sale price for ROSEVEAN of £805,000 on 12th October 2018. For the value to have increased from £805,000 to £1,030,396 over the seven years and eight months to February 2025, the following assumptions must hold true:

• The value of ROSEVEAN has moved in line with the HPI for detached houses in the Cornwall local authority area.
• The October 2018 sale price of £805,000 represented a fair market value for the property.
• The size, condition, and specification of ROSEVEAN has not materially changed since October 2018.
