20 LANGLEY WAY 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 20 LANGLEY WAY sales from August 2011 and September 2017 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 2011 sale was for 54% above the HPI. So the extrapolation line tracks at 54% above the HPI over time, until the September 2017 sale, where it falls to 29% above the HPI. The line then continues to track at 29% above the HPI.

What might 20 LANGLEY WAY be worth now?

This is based on house price inflation of 11.4%, between September 2017 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 11.4% inflationary increase is applied to the most recent sale price for 20 LANGLEY WAY of £1,030,000 on 20th September 2017. For the value to have increased from £1,030,000 to £1,147,327 over the six years and nine months to December 2024, the following assumptions must hold true:
