The below graph shows the average detached house price in the North Hertfordshire local authority area over time, sourced from the HPI. The four 58 THIRLMERE sales between August 2000 and July 2010 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 June 2007 sale was for 10% below the HPI. So the extrapolation line tracks at 10% below the HPI over time, until the July 2010 sale, where it falls to 16% below the HPI. The line then continues to track at 16% below the HPI.

58 THIRLMERE might now be worth an estimated £671,841.
This is based on house price inflation of 84.1%, between July 2010 and May 2026, for detached houses, in the North Hertfordshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 84.1% inflationary increase is applied to the most recent sale price for 58 THIRLMERE of £364,995 on 23rd July 2010. For the value to have increased from £364,995 to £671,841 over the sixteen years and two months to May 2026, the following assumptions must hold true:
