Overview

About 21 Lon Y Fro

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

21 Lon Y Fro is a four-bedroom detached house in Pentyrch, Cardiff, Cardiff (CF15 9TE). It has a recorded floor area of 97 m² (around 1044 sq ft), construction records dating it to 1967-1975 and council tax band F. The latest certificate (April 2016) shows a D (score 61), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 84), a 2-band jump. The latest certificate is from April 2016, so improvements made since then won't be reflected.

Today's modelled estimate of £480,000 is 49.1% above the 2016 sale price. On a £-per-square-foot basis, the last sale (£308/sq ft) was about 30.2% above the typical sold price in the postcode. Last sold in August 2016, so it's been off the market for around 10 years.
