4 THOROLD STREET Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Boston local authority area over time, sourced from the HPI. The five 4 THOROLD STREET sales between April 1997 and August 2021 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 November 2012 sale was for 44% above the HPI. So the extrapolation line tracks at 44% above the HPI over time, until the August 2021 sale, where it falls to 4% above the HPI. The line then continues to track at 4% above the HPI.

What might 4 THOROLD STREET be worth now?

4 THOROLD STREET might now be worth an estimated £174,499.

This is based on house price inflation of 12.9%, between August 2021 and August 2025, for semi-detached houses, in the Boston local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 12.9% inflationary increase is applied to the most recent sale price for 4 THOROLD STREET of £154,500 on 5th August 2021. For the value to have increased from £154,500 to £174,499 over the four years to August 2025, the following assumptions must hold true:

  • The value of 4 THOROLD STREET has moved in line with the HPI for semi-detached houses in the Boston local authority area.
  • The August 2021 sale price of £154,500 represented a fair market value for the property.
  • The size, condition, and specification of 4 THOROLD STREET has not materially changed since August 2021.
