Valuation method in detail
How the estimate is made
The estimate for Ty Isaf Farm is modelled from its 178 m² EPC floor area, its 3 recorded sales and recent sales of comparable homes in CF15 7JQ. It is an automated estimate, not a survey or mortgage valuation: condition, layout and improvements that aren't on record can move the real figure either way.
Where sold prices come from
Sold prices are HM Land Registry Price Paid Data, which covers residential sales in England and Wales since 1995. 3 sales are recorded for Ty Isaf Farm. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
Reading the EPC
Energy Performance Certificates rate homes from A (most efficient) to G and last 10 years. The latest one for Ty Isaf Farm was lodged in July 2012 at band D and expired in July 2022, so a new one is needed to sell or let. Floor area, heating and insulation details on this page come from it.
Planning records
Planning applications are collected from local authority registers through PlanIt. 2 applications are matched to Ty Isaf Farm. Councils sometimes file applications under a different address format, and applications on neighbouring land aren't listed here; the report covers both.
Area figures
Crime is police-recorded street-level data over the last 13 months, which places each incident at an approximate point. Schools and stops are measured in a straight line from CF15 7JQ.
Council tax band
Ty Isaf Farm is in council tax band G. Bands are set by the Valuation Office Agency from historic values (1 April 1991 in England, 1 April 2003 in Wales), not today's price; the amount you pay depends on the council's rate for the band.
