The list price of £800,000 is difficult to assess without knowing the exact size of the land and the permitted development opportunities. Nearby property prices vary significantly, ranging from below £400,000 to over £1 million. The price appears to be within the general range for the area, considering that this is a plot for development. However, the lack of square footage information and potential planning permission complications prevents a definitive conclusion on its value.

The aerial images show the land is largely undeveloped. There is no visible structure apart from what looks like potentially a previous structure that could be in need of significant work. While the land itself might be in good condition, the lack of any structure or detail prevents a higher score.

Warlingham is a desirable residential area in Surrey, known for its good schools, relatively easy access to London via train, and green spaces. The proximity to various amenities, including schools (Hamsey Green Primary, Warlingham School, and Warlingham Village Primary School are all within a reasonable distance) and train stations (Upper Warlingham, Whyteleafe, and others) makes it an attractive location. However, the exact location of the plot within Kingswood Lane isn’t specified in the data, so I cannot determine if it has any particular advantages or disadvantages within the area. A general location score is given based on the reputation of the area itself.

The plot appears to be reasonably sized based on the aerial image provided, suitable for potential development. It has a good depth, which is advantageous. However, the exact dimensions are not given which prevents a more precise assessment. The score reflects this uncertainty.
