8 SIBLEY AVENUE 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 8 SIBLEY AVENUE sales from August 2008 and May 2014 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 2008 sale was for 7% below the HPI. So the extrapolation line tracks at 7% below the HPI over time, until the May 2014 sale, where it rises to 38% above the HPI. The line then continues to track at 38% above the HPI.

What might 8 SIBLEY AVENUE be worth now?

8 SIBLEY AVENUE might now be worth an estimated £1,036,593.

This is based on house price inflation of 59.5%, between May 2014 and February 2025, 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 59.5% inflationary increase is applied to the most recent sale price for 8 SIBLEY AVENUE of £650,000 on 29th May 2014. For the value to have increased from £650,000 to £1,036,593 over the eleven years and three months to February 2025, the following assumptions must hold true:

• The value of 8 SIBLEY AVENUE has moved in line with the HPI for semi-detached houses in the St Albans local authority area.
• The May 2014 sale price of £650,000 represented a fair market value for the property.
