Although it's tempting to shell out a million or two on a stately home (like a historic castle in Scotland), since it seems like you're getting way more for your money, it's the repair and maintenance fees that can be insane.

This chateau, on the other hand, appears to be in good condition and I reckon that much of the costs would involve hiring gardeners and landscapers to keep the property in good shape.

Edit: I can't imagine what the heating bills are like.
