Valuation method in detail
How the estimate is made
The estimate for 4 Tai Dyffryn is modelled from its 121 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in CF15 7TS. 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. 2 sales are recorded for 4 Tai Dyffryn. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
Reading the EPC

Planning records
Planning applications are collected from local authority registers through PlanIt. None is matched to 4 Tai Dyffryn. Councils sometimes file applications under a different address format, and applications on neighbouring land aren't listed here; the report covers both.

Council tax band
4 Tai Dyffryn is in council tax band D. 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.
