55 LANSDOWNE AVENUE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Slough local authority area over time, sourced from the HPI. The four 55 LANSDOWNE AVENUE sales between February 1996 and June 2010 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 October 2004 sale was for 37% above the HPI. So the extrapolation line tracks at 37% above the HPI over time, until the June 2010 sale, where it rises to 41% above the HPI. The line then continues to track at 41% above the HPI.

What might 55 LANSDOWNE AVENUE be worth now?

This is based on house price inflation of 103.7%, between June 2010 and February 2025, for semi-detached houses, in the Slough local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 103.7% inflationary increase is applied to the most recent sale price for 55 LANSDOWNE AVENUE of £325,000 on 14th June 2010. For the value to have increased from £325,000 to £662,000 over the fifteen years and four months to February 2025, the following assumptions must hold true:
