15 SYDENHAM HILL Price Paid vs. HPI Average

The below graph shows the average detached house price in the Southwark local authority area over time, sourced from the HPI. The three 15 SYDENHAM HILL sales between September 1996 and September 2024 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 2006 sale was for 75% above the HPI. So the extrapolation line tracks at 75% above the HPI over time, until the September 2024 sale, where it falls to 61% above the HPI. The line then continues to track at 61% above the HPI.

What might 15 SYDENHAM HILL be worth now?

This is based on house price deflation of 4.6%, between September 2024 and December 2024, for detached houses, in the Southwark local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 4.6% deflationary decrease is applied to the most recent sale price for 15 SYDENHAM HILL of £2,700,000 on 20th September 2024. For the value to have decreased from £2,700,000 to £2,576,318 over the nine months to December 2024, the following assumptions must hold true:

• The value of 15 SYDENHAM HILL has moved in line with the HPI for detached houses in the Southwark local authority area.
• The September 2024 sale price of £2,700,000 represented a fair market value for the property.
