25 GWYNNE GARDENS Price Paid vs. HPI Average

The below graph shows the average detached house price in the Mid Sussex local authority area over time, sourced from the HPI. The two 25 GWYNNE GARDENS sales from March 2008 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 March 2008 sale was for 22% below the HPI. So the extrapolation line tracks at 22% below the HPI over time, until the September 2014 sale, where it rises to 18% below the HPI. The line then continues to track at 18% below the HPI.

What might 25 GWYNNE GARDENS be worth now?

This is based on house price inflation of 44.5%, between September 2014 and December 2024, for detached houses, in the Mid Sussex local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 44.5% inflationary increase is applied to the most recent sale price for 25 GWYNNE GARDENS of £420,000 on 30th September 2014. For the value to have increased from £420,000 to £606,859 over the nine years and nine months to December 2024, the following assumptions must hold true:

• The September 2014 sale price of £420,000 represented a fair market value for the property.
