1 TRETHELLAN HILL 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 four 1 TRETHELLAN HILL sales between July 1995 and December 2018 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 February 2017 sale was for 34% above the HPI. So the extrapolation line tracks at 34% above the HPI over time, until the December 2018 sale, where it rises to 60% above the HPI. The line then continues to track at 60% above the HPI.

What might 1 TRETHELLAN HILL be worth now?

This is based on house price inflation of 30.3%, between December 2018 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 30.3% inflationary increase is applied to the most recent sale price for 1 TRETHELLAN HILL of £545,000 on 17th December 2018. For the value to have increased from £545,000 to £709,867 over the six years to December 2024, the following assumptions must hold true:

• The value of 1 TRETHELLAN HILL has moved in line with the HPI for detached houses in the Cornwall local authority area.
• The December 2018 sale price of £545,000 represented a fair market value for the property.
