The below graph shows the average semi-detached house price in the Arun local authority area over time, sourced from the HPI. The two 21 MALLON DENE sales from August 2012 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 August 2012 sale was for 10% above the HPI. So the extrapolation line tracks at 10% above the HPI over time, until the September 2014 sale, where it falls to 5% above the HPI. The line then continues to track at 5% above the HPI.
21 MALLON DENE might now be worth an estimated £376,525.
This is based on house price inflation of 50.6%, between September 2014 and March 2025, for semi-detached houses, in the Arun local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 50.6% inflationary increase is applied to the most recent sale price for 21 MALLON DENE of £250,000 on 22nd September 2014. For the value to have increased from £250,000 to £376,525 over the eleven years and six months to March 2025, the following assumptions must hold true:
