AI Summary
This is a spacious, no-chain detached family home on a large corner plot in CF5, offering generous accommodation across three floors with a south-west facing garden and garage — features that are genuinely attractive for family buyers. However, the asking price of £400,000 sits above the 24-month comp median of £386,250, and the property requires a meaningful cosmetic renovation budget on top of purchase costs. Buyers should negotiate carefully, factor in £20,000–£30,000 for modernisation, and verify the attic conversion has the necessary building regulations sign-off.
