Considering the property’s location, size (1077 sqft), and the presence of a large garden, the list price of £520,000 appears relatively reasonable. Though there is a degree of required updating, this is offset by the desirability of the area and the substantial garden space. Comparables are limited in the provided data, with price per sqft unavailable due to missing data. However, a guide price of £520,000 - £550,000 suggests the listing price is on the lower end of the range and reflects the required modernisation, which is within reason.

The property shows some signs of wear and tear, and some rooms are sparsely furnished with existing fittings which may not appeal to all buyers. While the structure appears sound and the bathroom seems recently updated, there is room for improvement and modernization in many parts, particularly the kitchen which may require updates to appeal to most buyers. Overall, the condition of the property is acceptable but not exceptional.

Preston Park Avenue in Brighton is a highly desirable location known for its proximity to Preston Park, excellent schools (several within a kilometer radius boast ‘Good’ or ‘Outstanding’ Ofsted ratings), and good transport links. The nearby London Road station provides convenient access to Brighton city centre and beyond. This contributes to a high score for location.

The property boasts a significant rear garden, providing ample outdoor space. The garden is relatively mature but could benefit from some landscaping to enhance its overall aesthetic. The large size warrants a high score despite its current state of maintenance.
