1A DEVONSHIRE 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 1A DEVONSHIRE ROAD sales from April 2007 and September 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 April 2007 sale was for 104% above the HPI. So the extrapolation line tracks at 104% above the HPI over time, until the September 2018 sale, where it falls to 96% above the HPI. The line then continues to track at 96% above the HPI.

What might 1A DEVONSHIRE ROAD be worth now?

1A DEVONSHIRE ROAD might now be worth an estimated £1,488,906.

This is based on house price inflation of 18.2%, between September 2018 and May 2026, 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 18.2% inflationary increase is applied to the most recent sale price for 1A DEVONSHIRE ROAD of £1,260,000 on 3rd September 2018. For the value to have increased from £1,260,000 to £1,488,906 over the eight years and four months to May 2026, the following assumptions must hold true:

  • The value of 1A DEVONSHIRE ROAD has moved in line with the HPI for semi-detached houses in the St Albans local authority area.
  • The September 2018 sale price of £1,260,000 represented a fair market value for the property.
  • The size, condition, and specification of 1A DEVONSHIRE ROAD has not materially changed since September 2018.
