The below graph shows the average semi-detached house price in the Telford and Wrekin local authority area over time, sourced from the HPI. The two 18 UNION STREET sales from December 2013 and July 2018 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 2013 sale was for 24% below the HPI. So the extrapolation line tracks at 24% below the HPI over time, until the July 2018 sale, where it rises to 12% above the HPI. The line then continues to track at 12% above the HPI.

18 UNION STREET might now be worth an estimated £227,652.

The 45.5% inflationary increase is applied to the most recent sale price for 18 UNION STREET of £156,500 on 13th July 2018. For the value to have increased from £156,500 to £227,652 over the seven years to July 2025, the following assumptions must hold true:
