18 GREENWAY 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 four 18 GREENWAY sales between May 2001 and December 2022 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 2015 sale was for 1% below the HPI. So the extrapolation line tracks at 1% below the HPI over time, until the December 2022 sale, where it rises to 6% above the HPI. The line then continues to track at 6% above the HPI.

What might 18 GREENWAY be worth now?

This is based on house price deflation of 0.5%, between December 2022 and June 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 0.5% deflationary decrease is applied to the most recent sale price for 18 GREENWAY of £1,265,000 on 16th December 2022. For the value to have decreased from £1,265,000 to £1,259,296 over the three years and six months to June 2025, the following assumptions must hold true:

• The value of 18 GREENWAY has moved in line with the HPI for detached houses in the St Albans local authority area.
• The December 2022 sale price of £1,265,000 represented a fair market value for the property.
• The size, condition, and specification of 18 GREENWAY has not materially changed since December 2022.
