11 COTTINGHAM GROVE Price Paid vs. HPI Average

The below graph shows the average terraced house price in the County Durham local authority area over time, sourced from the HPI. The two 11 COTTINGHAM GROVE sales from June 2010 and August 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 June 2010 sale was for 59% above the HPI. So the extrapolation line tracks at 59% above the HPI over time, until the August 2017 sale, where it falls to 48% above the HPI. The line then continues to track at 48% above the HPI.

What might 11 COTTINGHAM GROVE be worth now?

This is based on house price inflation of 37.1%, between August 2017 and May 2026, for terraced 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 37.1% inflationary increase is applied to the most recent sale price for 11 COTTINGHAM GROVE of £122,500 on 18th August 2017. For the value to have increased from £122,500 to £167,952 over the nine years and three months to May 2026, the following assumptions must hold true:
