AI Summary
This is a spacious, well-presented extended detached home in an affluent Cardiff suburb, offering over 300 sqm of living space with a south-facing garden, garage, and modern interior finishes. However, the asking price of £419,950 sits notably above the local comp median of £367,500, and the pre-1900 solid stone construction with an oil boiler presents ongoing running cost and EPC upgrade challenges. Buyers should commission a full structural survey given the age and construction type, and negotiate with the price premium in mind.
