13 GRASMERE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Wiltshire local authority area over time, sourced from the HPI. The two 13 GRASMERE sales from June 2015 and August 2025 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 2015 sale was for 39% below the HPI. So the extrapolation line tracks at 39% below the HPI over time, until the August 2025 sale, which was also at 39% below the HPI.

What might 13 GRASMERE be worth now?

13 GRASMERE might now be worth an estimated £311,675.

This is based on house price inflation of 0.5%, between August 2025 and April 2026, for detached houses, in the Wiltshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 0.5% inflationary increase is applied to the most recent sale price for 13 GRASMERE of £310,000 on 8th August 2025. For the value to have increased from £310,000 to £311,675 over the one year and four months to April 2026, the following assumptions must hold true:

• The value of 13 GRASMERE has moved in line with the HPI for detached houses in the Wiltshire local authority area.
• The August 2025 sale price of £310,000 represented a fair market value for the property.
• The size, condition, and specification of 13 GRASMERE has not materially changed since August 2025.
