12 RIVER AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Merthyr Tydfil local authority area over time, sourced from the HPI. The three 12 RIVER AVENUE sales between April 2014 and June 2024 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 May 2016 sale was for 40% above the HPI. So the extrapolation line tracks at 40% above the HPI over time, until the June 2024 sale, where it falls to 15% above the HPI. The line then continues to track at 15% above the HPI.

What might 12 RIVER AVENUE be worth now?

12 RIVER AVENUE might now be worth an estimated £273,618.

This is based on house price deflation of 6%, between June 2024 and February 2025, for detached houses, in the Merthyr Tydfil local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 6% deflationary decrease is applied to the most recent sale price for 12 RIVER AVENUE of £291,000 on 14th June 2024. For the value to have decreased from £291,000 to £273,618 over the one year and four months to February 2025, the following assumptions must hold true:
