43 PROSPECT LANE 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 43 PROSPECT LANE sales from April 1995 and March 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 April 1995 sale was for 109% above the HPI. So the extrapolation line tracks at 109% above the HPI over time, until the March 2014 sale, where it rises to 111% above the HPI. The line then continues to track at 111% above the HPI.

What might 43 PROSPECT LANE be worth now?

43 PROSPECT LANE might now be worth an estimated £2,606,527.

This is based on house price inflation of 58%, between March 2014 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 58% inflationary increase is applied to the most recent sale price for 43 PROSPECT LANE of £1,650,000 on 7th March 2014. For the value to have increased from £1,650,000 to £2,606,527 over the eleven years and one month to February 2025, the following assumptions must hold true:

• The value of 43 PROSPECT LANE has moved in line with the HPI for detached houses in the St Albans local authority area.
• The March 2014 sale price of £1,650,000 represented a fair market value for the property.
• The size, condition, and specification of 43 PROSPECT LANE has not materially changed since March 2014.
