15 BLATCHES CHASE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Southend-on-Sea local authority area over time, sourced from the HPI. The two 15 BLATCHES CHASE sales from May 2009 and February 2025 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 2009 sale was for 10% below the HPI. So the extrapolation line tracks at 10% below the HPI over time, until the February 2025 sale, where it rises to 4% below the HPI. The line then continues to track at 4% below the HPI.

What might 15 BLATCHES CHASE be worth now?

15 BLATCHES CHASE might now be worth an estimated £392,643.

This is based on house price deflation of 1.8%, between February 2025 and June 2025, for semi-detached houses, in the Southend-on-Sea local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 1.8% deflationary decrease is applied to the most recent sale price for 15 BLATCHES CHASE of £400,000 on 13th February 2025. For the value to have decreased from £400,000 to £392,643 over the eight months to June 2025, the following assumptions must hold true:

• The value of 15 BLATCHES CHASE has moved in line with the HPI for semi-detached houses in the Southend-on-Sea local authority area.
• The February 2025 sale price of £400,000 represented a fair market value for the property.
