15 MILL LANE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the North Somerset local authority area over time, sourced from the HPI. The two 15 MILL LANE sales from May 2010 and November 2010 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 May 2010 sale was for 19% above the HPI. So the extrapolation line tracks at 19% above the HPI over time, until the November 2010 sale, where it rises to 28% above the HPI. The line then continues to track at 28% above the HPI.

What might 15 MILL LANE be worth now?

15 MILL LANE might now be worth an estimated £427,329.

This is based on house price inflation of 80.3%, between November 2010 and December 2024, for semi-detached houses, in the North Somerset local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 80.3% inflationary increase is applied to the most recent sale price for 15 MILL LANE of £237,000 on 5th November 2010. For the value to have increased from £237,000 to £427,329 over the thirteen years and eleven months to December 2024, the following assumptions must hold true:

• The value of 15 MILL LANE has moved in line with the HPI for semi-detached houses in the North Somerset local authority area.
• The November 2010 sale price of £237,000 represented a fair market value for the property.
• The size, condition, and specification of 15 MILL LANE has not materially changed since November 2010.
