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 21 CHELMSFORD AVENUE sales from June 1998 and November 2024 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 1998 sale was for 16% below the HPI. So the extrapolation line tracks at 16% below the HPI over time, until the November 2024 sale, where it rises to 5% above the HPI. The line then continues to track at 5% above the HPI.
21 CHELMSFORD AVENUE might now be worth an estimated £432,384.
This is based on house price deflation of 0.6%, between November 2024 and December 2024, 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 0.6% deflationary decrease is applied to the most recent sale price for 21 CHELMSFORD AVENUE of £435,000 on 13th November 2024. For the value to have decreased from £435,000 to £432,384 over the eleven months to December 2024, the following assumptions must hold true:
