7 ROSECOMB Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the North Hertfordshire local authority area over time, sourced from the HPI. The two 7 ROSECOMB sales from March 2016 and September 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 March 2016 sale was for 10% above the HPI. So the extrapolation line tracks at 10% above the HPI over time, until the September 2021 sale, where it falls to 4% above the HPI. The line then continues to track at 4% above the HPI.

What might 7 ROSECOMB be worth now?

7 ROSECOMB might now be worth an estimated £501,428.

This is based on house price inflation of 14.6%, between September 2021 and April 2026, for semi-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 14.6% inflationary increase is applied to the most recent sale price for 7 ROSECOMB of £437,500 on 24th September 2021. For the value to have increased from £437,500 to £501,428 over the five years and five months to April 2026, the following assumptions must hold true:

• The value of 7 ROSECOMB has moved in line with the HPI for semi-detached houses in the North Hertfordshire local authority area.
• The September 2021 sale price of £437,500 represented a fair market value for the property.
• The size, condition, and specification of 7 ROSECOMB has not materially changed since September 2021.
