20 HARPER GROVE Price Paid vs. HPI Average

The below graph shows the average detached house price in the County Durham local authority area over time, sourced from the HPI. The two 20 HARPER GROVE sales from August 2017 and June 2021 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 1% below the HPI. So the extrapolation line tracks at 1% below the HPI over time, until the June 2021 sale, where it falls to 15% below the HPI. The line then continues to track at 15% below the HPI.

What might 20 HARPER GROVE be worth now?

This is based on house price inflation of 17.7%, between June 2021 and December 2024, for detached houses, in the County Durham local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 17.7% inflationary increase is applied to the most recent sale price for 20 HARPER GROVE of £170,000 on 25th June 2021. For the value to have increased from £170,000 to £200,086 over the two years and six months to December 2024, the following assumptions must hold true:

• The June 2021 sale price of £170,000 represented a fair market value for the property.
