18 CALDERMERE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the County Durham local authority area over time, sourced from the HPI. The two 18 CALDERMERE sales from September 2016 and February 2022 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 September 2016 sale was for 8% below the HPI. So the extrapolation line tracks at 8% below the HPI over time, until the February 2022 sale, where it rises to 11% above the HPI. The line then continues to track at 11% above the HPI.

What might 18 CALDERMERE be worth now?

18 CALDERMERE might now be worth an estimated £150,625.

This is based on house price inflation of 15.9%, between February 2022 and December 2024, for semi-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 15.9% inflationary increase is applied to the most recent sale price for 18 CALDERMERE of £129,950 on 18th February 2022. For the value to have increased from £129,950 to £150,625 over the one year and two months to December 2024, the following assumptions must hold true:

• The value of 18 CALDERMERE has moved in line with the HPI for semi-detached houses in the County Durham local authority area.
• The February 2022 sale price of £129,950 represented a fair market value for the property.
• The size, condition, and specification of 18 CALDERMERE has not materially changed since February 2022.
