21 OSPREY WAY Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Chelmsford local authority area over time, sourced from the HPI. The six 21 OSPREY WAY sales between September 1995 and May 2017 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 May 2007 sale was for 1% above the HPI. So the extrapolation line tracks at 1% above the HPI over time, until the May 2017 sale, where it falls to 2% below the HPI. The line then continues to track at 2% below the HPI.

What might 21 OSPREY WAY be worth now?

21 OSPREY WAY might now be worth an estimated £423,594.

This is based on house price inflation of 28.4%, between May 2017 and June 2025, for semi-detached houses, in the Chelmsford local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 28.4% inflationary increase is applied to the most recent sale price for 21 OSPREY WAY of £330,000 on 15th May 2017. For the value to have increased from £330,000 to £423,594 over the seven years and eleven months to June 2025, the following assumptions must hold true:

• The value of 21 OSPREY WAY has moved in line with the HPI for semi-detached houses in the Chelmsford local authority area.
• The May 2017 sale price of £330,000 represented a fair market value for the property.
