The below graph shows the average semi-detached house price in the Barnsley local authority area over time, sourced from the HPI. The two 21 MARAN AVENUE sales from September 2015 and December 2018 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 September 2015 sale was for 15% below the HPI. So the extrapolation line tracks at 15% below the HPI over time, until the December 2018 sale, where it rises to 14% below the HPI. The line then continues to track at 14% below the HPI.

21 MARAN AVENUE might now be worth an estimated £141,635.
This is based on house price inflation of 41.6%, between December 2018 and August 2025, for semi-detached houses, in the Barnsley local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 41.6% inflationary increase is applied to the most recent sale price for 21 MARAN AVENUE of £100,000 on 10th December 2018. For the value to have increased from £100,000 to £141,635 over the seven years and four months to August 2025, the following assumptions must hold true:
