It would cost more than $8 million to live in Downton Abbey and run it like an aristocratic BOSS for one whole year, but you’re good for it, aren’t you? Of course, as long as you stock the mansion with some official Downton soaps, you should be able to keep costs manageable.
Weren't such places intended as self-sustaining estates which supported local, rural populations? I understand why that wouldn't be viable in modern times, but I've gotten the impression these weren't money pits in the 18th and 19th centuries. Could be wrong though. I'm no historian.
