Considering the location and the need for modernisation, the list price of £500,000 seems reasonably priced. While there is a lack of precise square footage data for comparable properties, the nearby sales prices and overall market trends in the area suggest the price is within the range of expectations for a three-bedroom semi-detached house requiring some updating. However, further information on the precise size and quality of the property is necessary to give a more precise valuation.

Based on the photographs, the property appears to be in fair condition, but it is in need of some updating and modernisation. The interior shows dated features, worn carpets, and requires some cosmetic work throughout. While the structure appears sound, the overall condition is not excellent, hence the moderate score.

The property is situated in Clifton Gardens, Hillingdon, which benefits from proximity to several highly-rated schools such as Swakeleys School for Girls (Outstanding Ofsted rating) and St Bernadette Catholic Primary School (Good Ofsted rating). The location also offers relatively easy access to transport links, although they are not within walking distance. The average house prices in nearby streets suggest the area is desirable, contributing to the higher score.

The property includes a garden, which is a positive feature. However, based on the images, the garden seems relatively small and requires maintenance. This is reflected in the mid-range score. The lack of a precise plot size in the provided data makes a definitive judgment on garden size more challenging.
