11 MARTINGALE 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 three 11 MARTINGALE sales between April 2004 and November 2015 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 August 2013 sale was for 73% above the HPI. So the extrapolation line tracks at 73% above the HPI over time, until the November 2015 sale, where it falls to 58% above the HPI. The line then continues to track at 58% above the HPI.

What might 11 MARTINGALE be worth now?

This is based on house price inflation of 44.5%, between November 2015 and April 2026, 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 44.5% inflationary increase is applied to the most recent sale price for 11 MARTINGALE of £535,000 on 20th November 2015. For the value to have increased from £535,000 to £772,858 over the eleven years and seven months to April 2026, the following assumptions must hold true:

• The value of 11 MARTINGALE has moved in line with the HPI for detached houses in the Castle Point local authority area.
• The November 2015 sale price of £535,000 represented a fair market value for the property.
