About 21 Carmarthen Street
21 Carmarthen Street is a two-bedroom mid-terrace house in Gloucester (GL1 4SX). It has a recorded floor area of 71 m² (around 764 sq ft), construction records dating it to 1900-1929 and council tax band A. The latest certificate (April 2009) shows a D (score 63), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 73). The latest certificate is from April 2009, so improvements made since then won't be reflected.
It hasn't traded since July 2001, a hold of 25 years that's notably long for the area. 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 £153,000 sits 209.1% above the 2001 sale of £49,500. On a £-per-square-foot basis, the last sale (£65/sq ft) was about 41.8% below the postcode norm.
