11 SALISBURY AVENUE 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 two 11 SALISBURY AVENUE sales from December 2006 and October 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 December 2006 sale was for 325% above the HPI. So the extrapolation line tracks at 325% above the HPI over time, until the October 2024 sale, where it falls to 183% above the HPI. The line then continues to track at 183% above the HPI.

What might 11 SALISBURY AVENUE be worth now?

This is based on house price inflation of 0.2%, between October 2024 and February 2025, 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 0.2% inflationary increase is applied to the most recent sale price for 11 SALISBURY AVENUE of £3,500,000 on 28th October 2024. For the value to have increased from £3,500,000 to £3,507,425 over the one year and eight months to February 2025, the following assumptions must hold true:
