19 SYLVESTER AVENUE 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 two 19 SYLVESTER AVENUE sales from January 2007 and January 2015 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 January 2007 sale was for 15% above the HPI. So the extrapolation line tracks at 15% above the HPI over time, until the January 2015 sale, where it falls to 12% above the HPI. The line then continues to track at 12% above the HPI.

What might 19 SYLVESTER AVENUE be worth now?

19 SYLVESTER AVENUE might now be worth an estimated £1,180,715.

This is based on house price inflation of 38%, between January 2015 and February 2025, 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 38% inflationary increase is applied to the most recent sale price for 19 SYLVESTER AVENUE of £855,750 on 16th January 2015. For the value to have increased from £855,750 to £1,180,715 over the nine years and eleven months to February 2025, the following assumptions must hold true:

• The value of 19 SYLVESTER AVENUE has moved in line with the HPI for detached houses in the Bromley local authority area.
• The January 2015 sale price of £855,750 represented a fair market value for the property.
