18 BACK STREET Price Paid vs. HPI Average

The below graph shows the average detached house price in the Dorset local authority area over time, sourced from the HPI. The two 18 BACK STREET sales from September 2001 and June 2006 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 September 2001 sale was for 53% above the HPI. So the extrapolation line tracks at 53% above the HPI over time, until the June 2006 sale, where it falls to 47% above the HPI. The line then continues to track at 47% above the HPI.

What might 18 BACK STREET be worth now?

18 BACK STREET might now be worth an estimated £775,908.

This is based on house price inflation of 70.5%, between June 2006 and February 2025, for detached houses, in the Dorset local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 70.5% inflationary increase is applied to the most recent sale price for 18 BACK STREET of £455,000 on 28th June 2006. For the value to have increased from £455,000 to £775,908 over the nineteen years and four months to February 2025, the following assumptions must hold true:

• The value of 18 BACK STREET has moved in line with the HPI for detached houses in the Dorset local authority area.
• The June 2006 sale price of £455,000 represented a fair market value for the property.
• The size, condition, and specification of 18 BACK STREET has not materially changed since June 2006.
