11 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 three 11 SAUNCEY AVENUE sales between October 1996 and March 2015 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 July 2010 sale was for 86% above the HPI. So the extrapolation line tracks at 86% above the HPI over time, until the March 2015 sale, where it falls to 74% above the HPI. The line then continues to track at 74% above the HPI.

What might 11 SAUNCEY AVENUE be worth now?

This is based on house price inflation of 40.8%, between March 2015 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 40.8% inflationary increase is applied to the most recent sale price for 11 SAUNCEY AVENUE of £1,540,000 on 17th March 2015. For the value to have increased from £1,540,000 to £2,168,048 over the eight years and three months to December 2024, the following assumptions must hold true:

• The value of 11 SAUNCEY AVENUE has moved in line with the HPI for detached houses in the St Albans local authority area.
• The March 2015 sale price of £1,540,000 represented a fair market value for the property.
