51 THE KNOLL Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the City of Plymouth local authority area over time, sourced from the HPI. The three 51 THE KNOLL sales between November 1996 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 June 2007 sale was for 10% above the HPI. So the extrapolation line tracks at 10% above the HPI over time, until the August 2021 sale, where it rises to 21% above the HPI. The line then continues to track at 21% above the HPI.

What might 51 THE KNOLL be worth now?

51 THE KNOLL might now be worth an estimated £317,105.

This is based on house price inflation of 17.4%, between August 2021 and December 2024, for semi-detached houses, in the City of Plymouth local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 17.4% inflationary increase is applied to the most recent sale price for 51 THE KNOLL of £270,000 on 13th August 2021. For the value to have increased from £270,000 to £317,105 over the two years and eight months to December 2024, the following assumptions must hold true:

• The value of 51 THE KNOLL has moved in line with the HPI for semi-detached houses in the City of Plymouth local authority area.
• The August 2021 sale price of £270,000 represented a fair market value for the property.
