12 MILLFIELDS 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 12 MILLFIELDS sales from April 2013 and November 2015 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 April 2013 sale was for 22% below the HPI. So the extrapolation line tracks at 22% below the HPI over time, until the November 2015 sale, where it rises to 37% above the HPI. The line then continues to track at 37% above the HPI.

What might 12 MILLFIELDS be worth now?

12 MILLFIELDS might now be worth an estimated £323,931.

This is based on house price inflation of 43.2%, between November 2015 and February 2025, 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 43.2% inflationary increase is applied to the most recent sale price for 12 MILLFIELDS of £226,250 on 18th November 2015. For the value to have increased from £226,250 to £323,931 over the ten years and nine months to February 2025, the following assumptions must hold true:
