10 COSGROVE AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Southend-on-Sea local authority area over time, sourced from the HPI. The two 10 COSGROVE AVENUE sales from June 2011 and September 2014 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 June 2011 sale was for 24% above the HPI. So the extrapolation line tracks at 24% above the HPI over time, until the September 2014 sale, where it rises to 111% above the HPI. The line then continues to track at 111% above the HPI.

What might 10 COSGROVE AVENUE be worth now?

10 COSGROVE AVENUE might now be worth an estimated £1,315,086.

This is based on house price inflation of 64.4%, between September 2014 and February 2025, for 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 64.4% inflationary increase is applied to the most recent sale price for 10 COSGROVE AVENUE of £800,000 on 5th September 2014. For the value to have increased from £800,000 to £1,315,086 over the eleven years and seven months to February 2025, the following assumptions must hold true:

• The value of 10 COSGROVE AVENUE has moved in line with the HPI for detached houses in the Southend-on-Sea local authority area.
• The September 2014 sale price of £800,000 represented a fair market value for the property.
