SUNNYSIDE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Darlington local authority area over time, sourced from the HPI. The four SUNNYSIDE sales between July 1995 and December 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 August 2014 sale was for 292% above the HPI. So the extrapolation line tracks at 292% above the HPI over time, until the December 2016 sale, where it rises to 313% above the HPI. The line then continues to track at 313% above the HPI.

What might SUNNYSIDE be worth now?

SUNNYSIDE might now be worth an estimated £696,139.

This is based on house price inflation of 31.3%, between December 2016 and December 2024, for semi-detached houses, in the Darlington local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 31.3% inflationary increase is applied to the most recent sale price for SUNNYSIDE of £530,200 on 16th December 2016. For the value to have increased from £530,200 to £696,139 over the eight years to December 2024, the following assumptions must hold true:

• The value of SUNNYSIDE has moved in line with the HPI for semi-detached houses in the Darlington local authority area.
• The December 2016 sale price of £530,200 represented a fair market value for the property.
• The size, condition, and specification of SUNNYSIDE has not materially changed since December 2016.
