Considering the property’s size, condition, and location in St. Mellons, the list price of £290,000 appears reasonably competitive, given the average price of similar properties on Willow Grove which is stated as £247,500. While the lack of precise square footage data for comparable properties makes precise per-square-foot analysis impossible, this price is still justifiable given that it is a 3-bedroom detached house. The price is therefore at the higher end of the market but not excessively so. This indicates good value for money compared to similar properties in the area.

Based on the provided photos, the property appears to be in good, well-maintained condition. The interior shows recent renovations or updates, particularly the kitchen and flooring. However, some areas such as one bedroom appear less updated and slightly cluttered, preventing a higher score.

The property is located in St. Mellons, Cardiff, a generally popular residential area. Its proximity to several primary schools (within approximately 1 km) and its relatively close distance to Cardiff city centre via road links (information not explicitly given but inferred from the context) contributes to a favorable location score. However, the lack of specific details on local amenities and the distance to key transport hubs (other than train stations at a considerable distance) prevents a higher score.

The property has a garden of reasonable size, as shown in the photos. While not extensive, it offers sufficient outdoor space for a family home. This justifies the above-average score compared to other properties in the area.
