38 CASSIOBURY PARK AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Watford local authority area over time, sourced from the HPI. The two 38 CASSIOBURY PARK AVENUE sales from August 2014 and November 2018 have been plotted on the graph.

For example, the August 2014 sale was for 48% above the HPI. So the extrapolation line tracks at 48% above the HPI over time, until the November 2018 sale, where it falls to 26% above the HPI.

This is based on house price inflation of 10.4%, between November 2018 and December 2024, for detached houses, in the Watford local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 10.4% inflationary increase is applied to the most recent sale price for 38 CASSIOBURY PARK AVENUE of £1,010,000 on 19th November 2018.
