19 NEWTON CLOSE 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 19 NEWTON CLOSE sales from August 1996 and April 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 August 1996 sale was for 29% below the HPI. So the extrapolation line tracks at 29% below the HPI over time, until the April 2019 sale, where it falls to 40% below the HPI. The line then continues to track at 40% below the HPI.

What might 19 NEWTON CLOSE be worth now?

19 NEWTON CLOSE might now be worth an estimated £740,037.

This is based on house price inflation of 23.3%, between April 2019 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 23.3% inflationary increase is applied to the most recent sale price for 19 NEWTON CLOSE of £600,000 on 12th April 2019. For the value to have increased from £600,000 to £740,037 over the six years and two months to February 2025, the following assumptions must hold true:

• The value of 19 NEWTON CLOSE has moved in line with the HPI for detached houses in the St Albans local authority area.
• The April 2019 sale price of £600,000 represented a fair market value for the property.
• The size, condition, and specification of 19 NEWTON CLOSE has not materially changed since April 2019.
