4 NORTHFIELD AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Harrow local authority area over time, sourced from the HPI. The two 4 NORTHFIELD AVENUE sales from June 2015 and October 2018 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 June 2015 sale was for 14% above the HPI. So the extrapolation line tracks at 14% above the HPI over time, until the October 2018 sale, where it falls to 8% above the HPI. The line then continues to track at 8% above the HPI.

What might 4 NORTHFIELD AVENUE be worth now?

4 NORTHFIELD AVENUE might now be worth an estimated £1,295,655.

This is based on house price inflation of 14.7%, between October 2018 and February 2025, for detached houses, in the Harrow local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 14.7% inflationary increase is applied to the most recent sale price for 4 NORTHFIELD AVENUE of £1,129,912 on 10th October 2018. For the value to have increased from £1,129,912 to £1,295,655 over the seven years and eight months to February 2025, the following assumptions must hold true:

  • The value of 4 NORTHFIELD AVENUE has moved in line with the HPI for detached houses in the Harrow local authority area.
  • The October 2018 sale price of £1,129,912 represented a fair market value for the property.
  • The size, condition, and specification of 4 NORTHFIELD AVENUE has not materially changed since October 2018.
