12 ARNE GROVE Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Bromley local authority area over time, sourced from the HPI. The four 12 ARNE GROVE sales between January 1997 and March 2025 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 2007 sale was for 2% above the HPI. So the extrapolation line tracks at 2% above the HPI over time, until the March 2025 sale, where it falls to 17% below the HPI. The line then continues to track at 17% below the HPI.

What might 12 ARNE GROVE be worth now?

12 ARNE GROVE might now be worth an estimated £417,344.

This is based on house price inflation of 3.8%, between March 2025 and July 2025, for terraced houses, in the Bromley local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 3.8% inflationary increase is applied to the most recent sale price for 12 ARNE GROVE of £402,000 on 25th March 2025. For the value to have increased from £402,000 to £417,344 over the eight months to July 2025, the following assumptions must hold true:

• The value of 12 ARNE GROVE has moved in line with the HPI for terraced houses in the Bromley local authority area.
• The March 2025 sale price of £402,000 represented a fair market value for the property.
