20 JAMESON ROAD Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the St Albans local authority area over time, sourced from the HPI. The two 20 JAMESON ROAD sales from December 1997 and December 2014 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 December 1997 sale was for 36% above the HPI. So the extrapolation line tracks at 36% above the HPI over time, until the December 2014 sale, where it rises to 67% above the HPI. The line then continues to track at 67% above the HPI.

What might 20 JAMESON ROAD be worth now?

20 JAMESON ROAD might now be worth an estimated £1,223,578.

This is based on house price inflation of 39.8%, between December 2014 and June 2025, for semi-detached houses, in the St Albans local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 39.8% inflationary increase is applied to the most recent sale price for 20 JAMESON ROAD of £875,000 on 16th December 2014. For the value to have increased from £875,000 to £1,223,578 over the eleven years and six months to June 2025, the following assumptions must hold true:
