26 DECOY AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Barnet local authority area over time, sourced from the HPI. The two 26 DECOY AVENUE sales from July 1999 and October 1999 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 July 1999 sale was for 46% below the HPI. So the extrapolation line tracks at 46% below the HPI over time, until the October 1999 sale, where it rises to 36% below the HPI. The line then continues to track at 36% below the HPI.

What might 26 DECOY AVENUE be worth now?

The 289.6% inflationary increase is applied to the most recent sale price for 26 DECOY AVENUE of £260,000 on 20th October 1999. For the value to have increased from £260,000 to £1,012,969 over the 26 years and three months to July 2025, the following assumptions must hold true:
