Elektra - the Bona Vacania list does not give the value of the estates any more. Heir Hunters have to try to establish the value by finding out if a person owned the property they lived in (by checking with the Land Registry), and by looking at the 2003 Electoral Roll (the last one that was published). They can then allocate 'tiers' based on presumed values. Of course, this is not infallible, as borne out by the man on today's show who had £40,000 cash stashed inside his council home.
