41A BELSIZE LANE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Camden local authority area over time, sourced from the HPI. The three 41A BELSIZE LANE sales between January 2006 and August 2021 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 March 2011 sale was for 72% above the HPI. So the extrapolation line tracks at 72% above the HPI over time, until the August 2021 sale, where it falls to 29% above the HPI. The line then continues to track at 29% above the HPI.

What might 41A BELSIZE LANE be worth now?

This is based on house price deflation of 3%, between August 2021 and December 2024, for semi-detached houses, in the Camden local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 3% deflationary decrease is applied to the most recent sale price for 41A BELSIZE LANE of £2,610,000 on 13th August 2021. For the value to have decreased from £2,610,000 to £2,531,647 over the two years and eight months to December 2024, the following assumptions must hold true:

• The value of 41A BELSIZE LANE has moved in line with the HPI for semi-detached houses in the Camden local authority area.
• The August 2021 sale price of £2,610,000 represented a fair market value for the property.
