11 THORNTON GARTH Price Paid vs. HPI Average

The below graph shows the average detached house price in the Stockton-on-Tees local authority area over time, sourced from the HPI. The two 11 THORNTON GARTH sales from July 2001 and September 2016 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 July 2001 sale was for 135% above the HPI. So the extrapolation line tracks at 135% above the HPI over time, until the September 2016 sale, where it falls to 107% above the HPI. The line then continues to track at 107% above the HPI.

What might 11 THORNTON GARTH be worth now?

This is based on house price inflation of 28.5%, between September 2016 and December 2024, for detached houses, in the Stockton-on-Tees local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 28.5% inflationary increase is applied to the most recent sale price for 11 THORNTON GARTH of £440,000 on 28th September 2016. For the value to have increased from £440,000 to £565,460 over the seven years and nine months to December 2024, the following assumptions must hold true:
