21 RIDGEWOOD GARDENS 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 21 RIDGEWOOD GARDENS sales from May 2010 and March 2016 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 May 2010 sale was for 36% below the HPI. So the extrapolation line tracks at 36% below the HPI over time, until the March 2016 sale, where it falls to 37% below the HPI. The line then continues to track at 37% below the HPI.

What might 21 RIDGEWOOD GARDENS be worth now?

21 RIDGEWOOD GARDENS might now be worth an estimated £780,070.

This is based on house price inflation of 24.8%, between March 2016 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 24.8% inflationary increase is applied to the most recent sale price for 21 RIDGEWOOD GARDENS of £625,000 on 30th March 2016. For the value to have increased from £625,000 to £780,070 over the nine years and one month to February 2025, the following assumptions must hold true:

  • The value of 21 RIDGEWOOD GARDENS has moved in line with the HPI for detached houses in the St Albans local authority area.
  • The March 2016 sale price of £625,000 represented a fair market value for the property.
  • The size, condition, and specification of 21 RIDGEWOOD GARDENS has not materially changed since March 2016.
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.
