Before you offer on a home on Castle Way: the checks to raise with your surveyor and conveyancer, whether an asking price stands up against what sold nearby, how prices here have moved since 1995, what it costs to run a home, and a buyer's report for every home on the street.
Checks tied to a spot (flood, radon, ground, noise, distances) are measured at ME19 5HF, where most of the street's homes are. A long street can differ from end to end: open a postcode for its own buying page.
Radon: up to 5–10% of homes above the action levelThis 1 km square includes a radon affected area. Ask whether the home has been tested; a three-month test is simple and cheap, and only a test shows a home's level (UKHSA/BGS).

Values: sales since 2021 of homes with an energy certificate (bedrooms estimated from its rooms), carried to today on the local price index; the cheaper quarter is what a quarter of them go for under. Rents are estimates: the council's typical private rent (ONS) adjusted for how values here compare. Gross yield = a year's rent ÷ value, before costs. Compare it with other places
