TREYNWYNS 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 TREYNWYNS sales between March 1997 and May 2019 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 2011 sale was for 25% above the HPI. So the extrapolation line tracks at 25% above the HPI over time, until the May 2019 sale, where it falls to 24% above the HPI. The line then continues to track at 24% above the HPI.

What might TREYNWYNS be worth now?

TREYNWYNS might now be worth an estimated £551,161.

This is based on house price inflation of 32.8%, between May 2019 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 32.8% inflationary increase is applied to the most recent sale price for TREYNWYNS of £415,000 on 17th May 2019. For the value to have increased from £415,000 to £551,161 over the four years and five months to December 2024, the following assumptions must hold true:

• The value of TREYNWYNS has moved in line with the HPI for detached houses in the Cornwall local authority area.
• The May 2019 sale price of £415,000 represented a fair market value for the property.
• The size, condition, and specification of TREYNWYNS has not materially changed since May 2019.
