TY FFYNNON Price Paid vs. HPI Average

The below graph shows the average detached house price in the Monmouthshire local authority area over time, sourced from the HPI. The two TY FFYNNON sales from April 2000 and May 2002 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 April 2000 sale was for 13% below the HPI. So the extrapolation line tracks at 13% below the HPI over time, until the May 2002 sale, where it falls to 40% below the HPI. The line then continues to track at 40% below the HPI.

What might TY FFYNNON be worth now?

TY FFYNNON might now be worth an estimated £299,211.

This is based on house price inflation of 199.2%, between May 2002 and July 2026, for detached houses, in the Monmouthshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 199.2% inflationary increase is applied to the most recent sale price for TY FFYNNON of £100,000 on 16th May 2002. For the value to have increased from £100,000 to £299,211 over the 23 years and ten months to July 2026, the following assumptions must hold true:

• The value of TY FFYNNON has moved in line with the HPI for detached houses in the Monmouthshire local authority area.
• The May 2002 sale price of £100,000 represented a fair market value for the property.
• The size, condition, and specification of TY FFYNNON has not materially changed since May 2002.
