The below graph shows the average semi-detached house price in the Doncaster local authority area over time, sourced from the HPI. The two 18 COULMAN STREET sales from December 2016 and June 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 December 2016 sale was for 27% below the HPI. So the extrapolation line tracks at 27% below the HPI over time, until the June 2017 sale, where it rises to 12% above the HPI. The line then continues to track at 12% above the HPI.

18 COULMAN STREET might now be worth an estimated £184,184.
This is based on house price inflation of 45.1%, between June 2017 and July 2025, 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 45.1% inflationary increase is applied to the most recent sale price for 18 COULMAN STREET of £126,950 on 9th June 2017. For the value to have increased from £126,950 to £184,184 over the seven years and eleven months to July 2025, the following assumptions must hold true:
