GRAY CORNERS Price Paid vs. HPI Average

The below graph shows the average detached house price in the St Albans local authority area over time, sourced from the HPI. The three GRAY CORNERS sales between July 1999 and July 2024 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 2019 sale was for 68% above the HPI. So the extrapolation line tracks at 68% above the HPI over time, until the July 2024 sale, where it rises to 107% above the HPI. The line then continues to track at 107% above the HPI.

What might GRAY CORNERS be worth now?

GRAY CORNERS might now be worth an estimated £2,577,932.

This is based on house price inflation of 6.3%, between July 2024 and December 2024, for 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 6.3% inflationary increase is applied to the most recent sale price for GRAY CORNERS of £2,425,000 on 22nd July 2024. For the value to have increased from £2,425,000 to £2,577,932 over the seven months to December 2024, the following assumptions must hold true:

• The value of GRAY CORNERS has moved in line with the HPI for detached houses in the St Albans local authority area.
• The July 2024 sale price of £2,425,000 represented a fair market value for the property.
• The size, condition, and specification of GRAY CORNERS has not materially changed since July 2024.
