17 DOWNING CLOSE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Arun local authority area over time, sourced from the HPI. The four 17 DOWNING CLOSE sales between December 1999 and April 2019 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 October 2018 sale was for 6% below the HPI. So the extrapolation line tracks at 6% below the HPI over time, until the April 2019 sale, where it falls to 15% below the HPI. The line then continues to track at 15% below the HPI.

What might 17 DOWNING CLOSE be worth now?

This is based on house price inflation of 20.5%, between April 2019 and May 2026, 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 20.5% inflationary increase is applied to the most recent sale price for 17 DOWNING CLOSE of £250,000 on 18th April 2019. For the value to have increased from £250,000 to £301,181 over the six years and eleven months to May 2026, the following assumptions must hold true:

• The value of 17 DOWNING CLOSE has moved in line with the HPI for semi-detached houses in the Arun local authority area.
• The April 2019 sale price of £250,000 represented a fair market value for the property.
