21 TRELAWNEY AVENUE 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 21 TRELAWNEY AVENUE sales from August 2017 and October 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 August 2017 sale was for 21% above the HPI. So the extrapolation line tracks at 21% above the HPI over time, until the October 2017 sale, where it falls to 18% above the HPI. The line then continues to track at 18% above the HPI.

What might 21 TRELAWNEY AVENUE be worth now?

21 TRELAWNEY AVENUE might now be worth an estimated £517,257.

This is based on house price inflation of 32.6%, between October 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 32.6% inflationary increase is applied to the most recent sale price for 21 TRELAWNEY AVENUE of £390,000 on 24th October 2017. For the value to have increased from £390,000 to £517,257 over the eight years and eight months to February 2025, the following assumptions must hold true:

  • The value of 21 TRELAWNEY AVENUE has moved in line with the HPI for detached houses in the Cornwall local authority area.
  • The October 2017 sale price of £390,000 represented a fair market value for the property.
  • The size, condition, and specification of 21 TRELAWNEY AVENUE has not materially changed since October 2017.
