COLNEFORD COTTAGE 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 COLNEFORD COTTAGE sales from November 2010 and September 2021 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 November 2010 sale was for 41% below the HPI. So the extrapolation line tracks at 41% below the HPI over time, until the September 2021 sale, where it rises to 18% above the HPI. The line then continues to track at 18% above the HPI.

What might COLNEFORD COTTAGE be worth now?

This is based on house price inflation of 8.9%, between September 2021 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 8.9% inflationary increase is applied to the most recent sale price for COLNEFORD COTTAGE of £1,350,000 on 13th September 2021. For the value to have increased from £1,350,000 to £1,469,519 over the two years and nine months to December 2024, the following assumptions must hold true:
