31 HARTFIELD AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Hertsmere local authority area over time, sourced from the HPI. The two 31 HARTFIELD AVENUE sales from July 2000 and August 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 July 2000 sale was for 15% above the HPI. So the extrapolation line tracks at 15% above the HPI over time, until the August 2018 sale, where it rises to 18% above the HPI. The line then continues to track at 18% above the HPI.

What might 31 HARTFIELD AVENUE be worth now?

This is based on house price inflation of 8.6%, between August 2018 and June 2025, for detached houses, in the Hertsmere local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 8.6% inflationary increase is applied to the most recent sale price for 31 HARTFIELD AVENUE of £1,275,000 on 3rd August 2018. For the value to have increased from £1,275,000 to £1,384,401 over the seven years and two months to June 2025, the following assumptions must hold true:
