The below graph shows the average semi-detached house price in the Middlesbrough local authority area over time, sourced from the HPI. The three 121 TRIMDON AVENUE sales between March 2002 and July 2022 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 September 2013 sale was for 15% above the HPI. So the extrapolation line tracks at 15% above the HPI over time, until the July 2022 sale, where it falls to 3% below the HPI. The line then continues to track at 3% below the HPI.

121 TRIMDON AVENUE might now be worth an estimated £145,070.
This is based on house price inflation of 7.5%, between July 2022 and May 2026, for semi-detached houses, in the Middlesbrough local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 7.5% inflationary increase is applied to the most recent sale price for 121 TRIMDON AVENUE of £135,000 on 15th July 2022. For the value to have increased from £135,000 to £145,070 over the four years and two months to May 2026, the following assumptions must hold true:
