15 MONK AVENUE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the York local authority area over time, sourced from the HPI. The three 15 MONK AVENUE sales between December 2005 and August 2020 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 August 2006 sale was for 22% above the HPI. So the extrapolation line tracks at 22% above the HPI over time, until the August 2020 sale, where it rises to 29% above the HPI. The line then continues to track at 29% above the HPI.

What might 15 MONK AVENUE be worth now?

The 25.2% inflationary increase is applied to the most recent sale price for 15 MONK AVENUE of £340,000 on 28th August 2020. For the value to have increased from £340,000 to £425,702 over the five years and two months to June 2025, the following assumptions must hold true:
