The below graph shows the average semi-detached house price in the Three Rivers local authority area over time, sourced from the HPI. The two 20 ROYCE GROVE sales from September 2001 and June 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 2001 sale was for 24% above the HPI. So the extrapolation line tracks at 24% above the HPI over time, until the June 2021 sale, where it falls to 5% above the HPI. The line then continues to track at 5% above the HPI.
20 ROYCE GROVE might now be worth an estimated £587,316.
This is based on house price inflation of 5.8%, between June 2021 and February 2025, for semi-detached houses, in the Three Rivers local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 5.8% inflationary increase is applied to the most recent sale price for 20 ROYCE GROVE of £555,000 on 28th June 2021. For the value to have increased from £555,000 to £587,316 over the four years and four months to February 2025, the following assumptions must hold true:
