BOSWYN 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 BOSWYN sales between December 1995 and September 2017 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 September 2003 sale was for 24% above the HPI. So the extrapolation line tracks at 24% above the HPI over time, until the September 2017 sale, which was also at 24% above the HPI.

What might BOSWYN be worth now?

BOSWYN might now be worth an estimated £543,637.

This is based on house price inflation of 33.7%, between September 2017 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 33.7% inflationary increase is applied to the most recent sale price for BOSWYN of £406,500 on 15th September 2017. For the value to have increased from £406,500 to £543,637 over the eight years and seven months to February 2025, the following assumptions must hold true:

• The value of BOSWYN has moved in line with the HPI for detached houses in the Cornwall local authority area.
• The September 2017 sale price of £406,500 represented a fair market value for the property.
• The size, condition, and specification of BOSWYN has not materially changed since September 2017.
