42 SAUNCEY 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 42 SAUNCEY AVENUE sales from August 2009 and April 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 August 2009 sale was for 44% above the HPI. So the extrapolation line tracks at 44% above the HPI over time, until the April 2021 sale, where it rises to 76% above the HPI. The line then continues to track at 76% above the HPI.

What might 42 SAUNCEY AVENUE be worth now?

This is based on house price inflation of 18%, between April 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 18% inflationary increase is applied to the most recent sale price for 42 SAUNCEY AVENUE of £1,860,000 on 28th April 2021. For the value to have increased from £1,860,000 to £2,195,625 over the two years and four months to December 2024, the following assumptions must hold true:
