74% of homes put up for sale were built before 1930, against 24% across England and Wales. For older homes RICS suggests a Level 3 survey: see which survey you need.
With 35% built before 1900, ask early whether a home is listed or in a conservation area, which limits the work you can do: see buying a listed building and buying in a conservation area.
