17 ANCASTER ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Bromley local authority area over time, sourced from the HPI. The four 17 ANCASTER ROAD sales between December 1996 and September 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 August 2013 sale was for 17% above the HPI. So the extrapolation line tracks at 17% above the HPI over time, until the September 2025 sale, where it falls to 11% above the HPI. The line then continues to track at 11% above the HPI.

What might 17 ANCASTER ROAD be worth now?

This is based on house price deflation of 0.8%, between September 2025 and July 2026, for detached 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 0.8% deflationary decrease is applied to the most recent sale price for 17 ANCASTER ROAD of £1,196,640 on 30th September 2025. For the value to have decreased from £1,196,640 to £1,187,570 over the one year and two months to July 2026, the following assumptions must hold true:

• The value of 17 ANCASTER ROAD has moved in line with the HPI for detached houses in the Bromley local authority area.
• The September 2025 sale price of £1,196,640 represented a fair market value for the property.
