The list price of £500,000 for a one-bedroom, one-bathroom flat of approximately 390 sqft in Marylebone is relatively competitive but not exceptional value. While comparable properties in the area command higher prices, reflecting the prime location, the age and condition of the property, as well as the absence of outdoor space, suggest the pricing is reasonable, though not a bargain. Nearby comparable properties are considerably more expensive, however, the lack of key details from these listing prevents any firm conclusion on the price per sqft.

Based on the provided photos, the property appears to be in reasonably good condition, though not luxurious. The bathroom and kitchen show some signs of wear and tear, and could benefit from some modernization to elevate the overall condition. The living space appears presentable but not recently renovated. Therefore, a mid-range score is assigned to reflect this moderate state of repair.

The property is located in Marylebone, a highly desirable area of London known for its upscale amenities, excellent schools, and convenient transport links. Proximity to Marylebone station (Chiltern Railways) and easy access to other central London locations via other nearby stations significantly boosts its appeal and justifies a high location score. The presence of well-regarded schools within walking distance further enhances its desirability for families and professionals.

The property listing explicitly states a plot size of 0.00 sqft, indicating no garden or significant external land. This lack of outdoor space warrants the lowest score for land.
