The asking price of £650,000 seems relatively reasonable considering comparable properties in the area; nearby properties are listed at around the same price. However, without specific square footage data for comparable properties, it’s difficult to give a definitive price-per-square-foot assessment. The fact that several other properties in the same street are listed for the same price makes the list price seem justified.

The property appears to be in good condition based on the provided photographs. The kitchen and bathroom seem recently renovated and modern. While some areas like the garden shed show signs of disuse, the overall presentation is well maintained and suggests a recent refurbishment, earning a high score in the condition category.

Hadley Highstone is a desirable area in Barnet, known for its Victorian charm and proximity to good schools and transport links. While the provided data does not show exact distances from the property to amenities, the nearby streets data suggests a reasonable location score, with Warwick Gardens, an area noted for high average house prices, being in close proximity. The presence of several highly-rated schools within a reasonable distance also contributes to a higher location score.

The property benefits from a garden, as evidenced by the photos, which is a significant advantage in a London location. Although the exact plot size is not stated, the images show a relatively well-sized garden for a terraced house in the area; a modest size but sizable enough to give it a decent score above average for the location.
