The list price of £300,000 seems reasonable given the apparent condition and the location in Leigh-on-Sea. However, the absence of square footage data for comparable properties and the lack of specific details regarding property type (house, flat, etc.) introduces some uncertainty. While nearby properties are substantially more expensive, this property is a smaller property. Therefore, a score of 7 is given accounting for the lack of comparative data.

Based on the provided photographs, the property appears to be in excellent condition. The photos showcase a recently renovated or refurbished interior with modern fixtures, fittings, and a fresh, clean aesthetic. There are no apparent signs of disrepair or deferred maintenance.

Leigh-on-Sea is a desirable coastal town with good transport links to London via c2c rail services. The proximity to schools, as noted in the data, adds to its family-friendly appeal. However, the specific location on Southsea Avenue may influence the score, as there is no information to assess the specific advantages or disadvantages of this particular street compared to other Leigh-on-Sea locations.

While the property includes a garden, the provided aerial photo shows it to be relatively small. It is not extensive enough to command a high score despite the presence of some garden space. The lack of precise plot size details in the provided data limits the scoring accuracy, hence this score reflects the visual assessment.
