1B MORTIMER ROAD 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 two 1B MORTIMER ROAD sales from September 2004 and March 2021 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 2004 sale was for 22% below the HPI. So the extrapolation line tracks at 22% below the HPI over time, until the March 2021 sale, where it falls to 25% below the HPI. The line then continues to track at 25% below the HPI.

What might 1B MORTIMER ROAD be worth now?

1B MORTIMER ROAD might now be worth an estimated £602,221.

This is based on house price inflation of 17.5%, between March 2021 and April 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 17.5% inflationary increase is applied to the most recent sale price for 1B MORTIMER ROAD of £512,500 on 31st March 2021. For the value to have increased from £512,500 to £602,221 over the four years and eleven months to April 2026, the following assumptions must hold true:

  • The value of 1B MORTIMER ROAD has moved in line with the HPI for detached houses in the North Hertfordshire local authority area.
  • The March 2021 sale price of £512,500 represented a fair market value for the property.
  • The size, condition, and specification of 1B MORTIMER ROAD has not materially changed since March 2021.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
