21 PARKSTONE AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Havering local authority area over time, sourced from the HPI. The two 21 PARKSTONE AVENUE sales from September 2013 and May 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 September 2013 sale was for 112% above the HPI. So the extrapolation line tracks at 112% above the HPI over time, until the May 2019 sale, where it rises to 283% above the HPI. The line then continues to track at 283% above the HPI.

What might 21 PARKSTONE AVENUE be worth now?

This is based on house price inflation of 17%, between May 2019 and December 2024, for detached houses, in the Havering local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 17% inflationary increase is applied to the most recent sale price for 21 PARKSTONE AVENUE of £2,600,000 on 17th May 2019. For the value to have increased from £2,600,000 to £3,042,359 over the four years and five months to December 2024, the following assumptions must hold true:
