Considering the average house price in the area is significantly higher, and the property is a plot of land with no building, the asking price of £20,000 appears reasonable. However, without knowing the exact plot size in square feet, a more precise assessment of the price-per-square-foot value is not possible. This lack of precise data prevents a higher score.

The images show an overgrown and unkempt plot that requires significant work before it can be used effectively. The presence of debris and the overall state of disrepair contribute to the lower score.

Several primary schools are within a reasonable distance, but other amenities like transportation links are not mentioned. The proximity to schools is a positive factor, but the lack of readily available information on other local amenities prevents a higher score.

The plot is relatively small, as evidenced by the aerial and plot plan images. While it offers space for development or a garden, its size is a limiting factor.
