21 NEW LANE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Doncaster local authority area over time, sourced from the HPI. The two 21 NEW LANE sales from November 2006 and January 2026 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 November 2006 sale was for 184% above the HPI. So the extrapolation line tracks at 184% above the HPI over time, until the January 2026 sale, where it rises to 203% above the HPI. The line then continues to track at 203% above the HPI.

What might 21 NEW LANE be worth now?

21 NEW LANE might now be worth an estimated £516,195.

This is based on house price deflation of 0.7%, between January 2026 and May 2026, for semi-detached houses, in the Doncaster local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 0.7% deflationary decrease is applied to the most recent sale price for 21 NEW LANE of £520,000 on 19th January 2026. For the value to have decreased from £520,000 to £516,195 over the eight months to May 2026, the following assumptions must hold true:

• The value of 21 NEW LANE has moved in line with the HPI for semi-detached houses in the Doncaster local authority area.
• The January 2026 sale price of £520,000 represented a fair market value for the property.
