All you need to move in is first month + security + hatred for James Bond.
#6. Hasard Cheratte
Located in the sleepy Belgian town of Cheratte at the very heart of Europe, this massive abandoned mine complex combines an ominous facade with a dignified title, much like Baron Destro, to form the perfect location for some old-fashioned continental terrorism. It offers all the amenities your villainous soul could desire, including a Gate of Evil, a mansion-like exterior, a looming Dark Tower, industrial equipment that could easily double as torture devices, and vast underground caverns over 1,300 feet deep for doomsday device/giant-mech-with-your-own-face parking.
