48 THIRLMERE Price Paid vs. HPI Average

The below graph shows the average detached house price in the North Hertfordshire local authority area over time, sourced from the HPI. The three 48 THIRLMERE sales between December 1999 and December 2018 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 2018 sale was for 34% below the HPI. So the extrapolation line tracks at 34% below the HPI over time, until the December 2018 sale, where it falls to 39% below the HPI. The line then continues to track at 39% below the HPI.

What might 48 THIRLMERE be worth now?

48 THIRLMERE might now be worth an estimated £475,131.

This is based on house price inflation of 12.7%, between December 2018 and February 2025, 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 12.7% inflationary increase is applied to the most recent sale price for 48 THIRLMERE of £421,500 on 10th December 2018. For the value to have increased from £421,500 to £475,131 over the seven years and ten months to February 2025, the following assumptions must hold true:

• The value of 48 THIRLMERE has moved in line with the HPI for detached houses in the North Hertfordshire local authority area.
• The December 2018 sale price of £421,500 represented a fair market value for the property.
