The list price of £850,000 for a 3-bedroom, 1-bathroom semi-detached house in N10 appears reasonable given its location and updated condition. The lack of precise square footage data for the property itself and comparable properties makes a conclusive price-per-square-foot analysis impossible. However, considering comparable properties in the area, and the evident refurbishment of some rooms, the price seems competitive, albeit not exceptionally high-value.

Based on the provided photos, the property appears to be in good condition. The kitchen and bathroom have been recently renovated or updated, showing modern fixtures and finishes. The living areas are presented well. While not perfect, the property does not seem to require extensive repair or renovations.

The property is located in The Vale, Coppetts, Barnet, a desirable area in North London. Its proximity to well-regarded schools like Coppetts Wood Primary School (Outstanding Ofsted rating) significantly enhances its desirability. The presence of nearby green spaces adds to its appeal. While transport links might not be directly on the doorstep, the relatively short distances to several stations on the Great Northern line provide reasonable access to central London.

The property has a garden, which is a positive. However, based on the photos, the garden size appears to be relatively small for a family home in London. More information on its precise dimensions and usable space is needed for a more accurate assessment.
