16 BLACKDOWN GROVE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Oldham local authority area over time, sourced from the HPI. The three 16 BLACKDOWN GROVE sales between June 2002 and September 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 October 2010 sale was for 6% above the HPI. So the extrapolation line tracks at 6% above the HPI over time, until the September 2021 sale, where it rises to 9% above the HPI. The line then continues to track at 9% above the HPI.

What might 16 BLACKDOWN GROVE be worth now?

This is based on house price inflation of 21.6%, between September 2021 and December 2024, for semi-detached houses, in the Oldham local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 21.6% inflationary increase is applied to the most recent sale price for 16 BLACKDOWN GROVE of £200,000 on 30th September 2021. For the value to have increased from £200,000 to £243,222 over the two years and nine months to December 2024, the following assumptions must hold true:
