13 FIRS 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 13 FIRS AVENUE sales from February 2003 and April 2007 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 February 2003 sale was for 50% below the HPI. So the extrapolation line tracks at 50% below the HPI over time, until the April 2007 sale, where it rises to 49% below the HPI. The line then continues to track at 49% below the HPI.

What might 13 FIRS AVENUE be worth now?

This is based on house price inflation of 98.7%, between April 2007 and February 2025, for detached houses, in the Barnet local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 98.7% inflationary increase is applied to the most recent sale price for 13 FIRS AVENUE of £400,000 on 11th April 2007. For the value to have increased from £400,000 to £794,857 over the eighteen years and two months to February 2025, the following assumptions must hold true:
