TRELAWNEY HOUSE 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 two TRELAWNEY HOUSE sales from October 1996 and November 2003 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 October 1996 sale was for 50% above the HPI. So the extrapolation line tracks at 50% above the HPI over time, until the November 2003 sale, where it rises to 63% above the HPI. The line then continues to track at 63% above the HPI.

What might TRELAWNEY HOUSE be worth now?

TRELAWNEY HOUSE might now be worth an estimated £711,839.

This is based on house price inflation of 92.4%, between November 2003 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 92.4% inflationary increase is applied to the most recent sale price for TRELAWNEY HOUSE of £370,000 on 18th November 2003. For the value to have increased from £370,000 to £711,839 over the 22 years and nine months to February 2025, the following assumptions must hold true:

• The value of TRELAWNEY HOUSE has moved in line with the HPI for detached houses in the Cornwall local authority area.
• The November 2003 sale price of £370,000 represented a fair market value for the property.
• The size, condition, and specification of TRELAWNEY HOUSE has not materially changed since November 2003.
