CARNFORTH 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 CARNFORTH sales between January 1998 and June 2002 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 July 2000 sale was for 23% below the HPI. So the extrapolation line tracks at 23% below the HPI over time, until the June 2002 sale, where it rises to 21% below the HPI. The line then continues to track at 21% below the HPI.

What might CARNFORTH be worth now?

CARNFORTH might now be worth an estimated £332,116.

This is based on house price inflation of 161.5%, between June 2002 and July 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 161.5% inflationary increase is applied to the most recent sale price for CARNFORTH of £127,000 on 10th June 2002. For the value to have increased from £127,000 to £332,116 over the 23 years and eleven months to July 2026, the following assumptions must hold true:

  • The value of CARNFORTH has moved in line with the HPI for detached houses in the Cornwall local authority area.
  • The June 2002 sale price of £127,000 represented a fair market value for the property.
  • The size, condition, and specification of CARNFORTH has not materially changed since June 2002.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
