1 OLD BOSTON Price Paid vs. HPI Average

The below graph shows the average detached house price in the St Helens local authority area over time, sourced from the HPI. The four 1 OLD BOSTON sales between April 1995 and January 2020 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 March 2016 sale was for 113% above the HPI. So the extrapolation line tracks at 113% above the HPI over time, until the January 2020 sale, where it falls to 99% above the HPI. The line then continues to track at 99% above the HPI.

What might 1 OLD BOSTON be worth now?

This is based on house price inflation of 42.8%, between January 2020 and February 2025, for detached houses, in the St Helens local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 42.8% inflationary increase is applied to the most recent sale price for 1 OLD BOSTON of £403,500 on 31st January 2020. For the value to have increased from £403,500 to £576,106 over the four years and eleven months to February 2025, the following assumptions must hold true:

• The value of 1 OLD BOSTON has moved in line with the HPI for detached houses in the St Helens local authority area.
