Overview

About 12 Cymmer Street

A plain-English summary derived from public records, EPC certificates, sold prices and local data.

12 Cymmer Street is a three-bedroom mid-terrace house in Cardiff (CF11 7AB). It has a recorded floor area of 96 m² (around 1035 sq ft), construction records dating it to before 1900 and council tax band E. The latest certificate (June 2009) shows an E (score 48), well below the UK norm with real room to improve. The recommended improvements would push it to D (score 61). The latest certificate is from June 2009, so improvements made since then won't be reflected. Period features are noted in the property record.

Today's modelled estimate of £304,000 is 48.3% above the 2016 sale price. On a £-per-square-foot basis, the last sale (£198/sq ft) was about 21.8% above the typical sold price in the postcode. Last sold in June 2016, so it's been off the market for around 10 years.

Where sold prices come from
Sold prices are HM Land Registry Price Paid Data, which covers residential sales in England and Wales since 1995. 2 sales are recorded for 12 Cymmer Street. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
