The list price of £650,000 seems reasonably competitive based on the provided data of similar properties. While precise square footage is missing, comparing it to other three-bedroom semi-detached houses in the area, with similar features, the price falls in line with general market trends for Carshalton. The lack of square footage data prevents a more precise analysis of price per square foot.

Based on the provided photos, the property appears to be in good overall condition. The extension appears modern, suggesting recent renovations, and the internal décor is contemporary. While there is evidence of wear and tear, such as some minor garden maintenance needed, there is nothing significant to bring down the score substantially.

The property is located in Carshalton, a suburban area in Greater London. Carshalton benefits from good transport links to London via train stations (Wallington, Carshalton, Carshalton Beeches being relatively close), and also has well-regarded schools within a reasonable distance, as indicated in the provided data. The proximity to amenities and green spaces adds to its appeal, making it a desirable location for families and commuters. However, it’s not in central London, hence a score less than 10.

The property has a garden, which is a positive aspect, particularly in a suburban setting. However, the size and landscaping are not specified, and based on the photographs it appears to be a moderately sized garden that could benefit from some improvements; this is not exceptionally large compared to others in the area.
