12B GROSVENOR SQUARE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Oldham local authority area over time, sourced from the HPI. The two 12B GROSVENOR SQUARE sales from December 2006 and September 2014 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 December 2006 sale was for 56% below the HPI. So the extrapolation line tracks at 56% below the HPI over time, until the September 2014 sale, where it rises to 53% below the HPI. The line then continues to track at 53% below the HPI.

What might 12B GROSVENOR SQUARE be worth now?

This is based on house price inflation of 79.8%, between September 2014 and December 2024, for 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 79.8% inflationary increase is applied to the most recent sale price for 12B GROSVENOR SQUARE of £90,500 on 30th September 2014. For the value to have increased from £90,500 to £162,749 over the nine years and nine months to December 2024, the following assumptions must hold true:
