156A HARPENDEN ROAD 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 156A HARPENDEN ROAD sales from May 2005 and February 2019 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 2005 sale was for 22% below the HPI. So the extrapolation line tracks at 22% below the HPI over time, until the February 2019 sale, where it rises to 22% above the HPI. The line then continues to track at 22% above the HPI.

What might 156A HARPENDEN ROAD be worth now?

156A HARPENDEN ROAD might now be worth an estimated £1,518,279.

This is based on house price inflation of 23.9%, between February 2019 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 23.9% inflationary increase is applied to the most recent sale price for 156A HARPENDEN ROAD of £1,225,000 on 21st February 2019. For the value to have increased from £1,225,000 to £1,518,279 over the four years and two months to December 2024, the following assumptions must hold true:

• The value of 156A HARPENDEN ROAD has moved in line with the HPI for detached houses in the St Albans local authority area.
• The February 2019 sale price of £1,225,000 represented a fair market value for the property.
