66 UNION STREET Price Paid vs. HPI Average

The below graph shows the average detached house price in the Rotherham local authority area over time, sourced from the HPI. The two 66 UNION STREET sales from May 2001 and July 2003 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 2001 sale was for 103% above the HPI. So the extrapolation line tracks at 103% above the HPI over time, until the July 2003 sale, where it rises to 160% above the HPI. The line then continues to track at 160% above the HPI.

What might 66 UNION STREET be worth now?

This is based on house price inflation of 142.8%, between July 2003 and February 2025, for detached houses, in the Rotherham local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 142.8% inflationary increase is applied to the most recent sale price for 66 UNION STREET of £299,000 on 4th July 2003. For the value to have increased from £299,000 to £725,958 over the 22 years and five months to February 2025, the following assumptions must hold true:
