31 AMBROSE 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 31 AMBROSE LANE sales from July 2006 and May 2018 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 2006 sale was for 8% above the HPI. So the extrapolation line tracks at 8% above the HPI over time, until the May 2018 sale, where it rises to 14% above the HPI. The line then continues to track at 14% above the HPI.

What might 31 AMBROSE LANE be worth now?

31 AMBROSE LANE might now be worth an estimated £1,416,460.

This is based on house price inflation of 20%, between May 2018 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 20% inflationary increase is applied to the most recent sale price for 31 AMBROSE LANE of £1,180,000 on 4th May 2018. For the value to have increased from £1,180,000 to £1,416,460 over the seven years and three months to February 2025, the following assumptions must hold true:

  • The value of 31 AMBROSE LANE has moved in line with the HPI for detached houses in the St Albans local authority area.
  • The May 2018 sale price of £1,180,000 represented a fair market value for the property.
  • The size, condition, and specification of 31 AMBROSE LANE has not materially changed since May 2018.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
