18 HASLEMERE GARDENS 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 five 18 HASLEMERE GARDENS sales between September 1995 and February 2020 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 November 2007 sale was for 71% above the HPI. So the extrapolation line tracks at 71% above the HPI over time, until the February 2020 sale, where it falls to 18% above the HPI. The line then continues to track at 18% above the HPI.

What might 18 HASLEMERE GARDENS be worth now?

18 HASLEMERE GARDENS might now be worth an estimated £1,898,418.

This is based on house price inflation of 15.8%, between February 2020 and August 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 15.8% inflationary increase is applied to the most recent sale price for 18 HASLEMERE GARDENS of £1,640,000 on 3rd February 2020. For the value to have increased from £1,640,000 to £1,898,418 over the four years and six months to August 2025, the following assumptions must hold true:

  • The value of 18 HASLEMERE GARDENS has moved in line with the HPI for detached houses in the Barnet local authority area.
  • The February 2020 sale price of £1,640,000 represented a fair market value for the property.
  • The size, condition, and specification of 18 HASLEMERE GARDENS has not materially changed since February 2020.
