11A SLEWINS LANE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Havering local authority area over time, sourced from the HPI. The two 11A SLEWINS LANE sales from April 2010 and January 2016 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 April 2010 sale was for 19% below the HPI. So the extrapolation line tracks at 19% below the HPI over time, until the January 2016 sale, where it rises to 12% below the HPI. The line then continues to track at 12% below the HPI.

What might 11A SLEWINS LANE be worth now?

11A SLEWINS LANE might now be worth an estimated £701,109.

This is based on house price inflation of 33.5%, between January 2016 and December 2024, for detached houses, in the Havering local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 33.5% inflationary increase is applied to the most recent sale price for 11A SLEWINS LANE of £525,000 on 15th January 2016. For the value to have increased from £525,000 to £701,109 over the seven years and one month to December 2024, the following assumptions must hold true:

• The value of 11A SLEWINS LANE has moved in line with the HPI for detached houses in the Havering local authority area.
• The January 2016 sale price of £525,000 represented a fair market value for the property.
