KING JOHN COTTAGE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Castle Point local authority area over time, sourced from the HPI. The two KING JOHN COTTAGE sales from January 2003 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 January 2003 sale was for 9% below the HPI. So the extrapolation line tracks at 9% below the HPI over time, until the August 2021 sale, where it rises to 25% above the HPI. The line then continues to track at 25% above the HPI.

What might KING JOHN COTTAGE be worth now?

KING JOHN COTTAGE might now be worth an estimated £578,971.

This is based on house price inflation of 5.3%, between August 2021 and February 2025, for detached houses, in the Castle Point local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 5.3% inflationary increase is applied to the most recent sale price for KING JOHN COTTAGE of £550,000 on 25th August 2021. For the value to have increased from £550,000 to £578,971 over the four years and six months to February 2025, the following assumptions must hold true:

• The value of KING JOHN COTTAGE has moved in line with the HPI for detached houses in the Castle Point local authority area.
• The August 2021 sale price of £550,000 represented a fair market value for the property.
