18 GRASMERE ROAD 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 18 GRASMERE ROAD sales between March 1998 and May 2016 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 April 2002 sale was for 91% above the HPI. So the extrapolation line tracks at 91% above the HPI over time, until the May 2016 sale, where it rises to 114% above the HPI. The line then continues to track at 114% above the HPI.

What might 18 GRASMERE ROAD be worth now?

18 GRASMERE ROAD might now be worth an estimated £1,028,337.

This is based on house price inflation of 40.7%, between May 2016 and December 2024, 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 40.7% inflationary increase is applied to the most recent sale price for 18 GRASMERE ROAD of £731,000 on 11th May 2016. For the value to have increased from £731,000 to £1,028,337 over the seven years and five months to December 2024, the following assumptions must hold true:

• The value of 18 GRASMERE ROAD has moved in line with the HPI for detached houses in the Castle Point local authority area.
• The May 2016 sale price of £731,000 represented a fair market value for the property.
• The size, condition, and specification of 18 GRASMERE ROAD has not materially changed since May 2016.
