18 SIDMOUTH CLOSE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Middlesbrough local authority area over time, sourced from the HPI. The four 18 SIDMOUTH CLOSE sales between July 2005 and July 2025 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 February 2022 sale was for 1% below the HPI. So the extrapolation line tracks at 1% below the HPI over time, until the July 2025 sale, which was also at 1% below the HPI.
