13 St James Street, Monmouth, NP25 3DL

13 St James Street is a three-bedroom mid-terrace house in Monmouth (NP25 3DL). It has a recorded floor area of 85 m² (around 915 sq ft), construction records dating it to before 1900 and council tax band E. It is a listed building, which means external alterations are tightly controlled but it may qualify for heritage tax reliefs. The latest certificate (September 2015) shows an E (score 48), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 77), a 2-band jump. The latest certificate is from September 2015, so improvements made since then won't be reflected.

Held since September 1998 — that's 28 years off the open market, well above the local norm. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £276,000 sits 392.9% above the 1998 sale of £56,000. On a £-per-square-foot basis, the last sale (£61/sq ft) was about 69.1% below the postcode norm. It lags the bulk of the postcode on energy efficiency (less efficient than 81% of similar EPCs).
