Let's start with what the housing is. Yes, it is instanced; lairs can't be constructed willy-nilly throughout the world. However, the housing is accessed from realistic points within the world, not some artificial housing hub. For instance, if you have the sewer lair, you select a manhole cover somewhere in the streets of Gotham or Metropolis. If you prefer a penthouse, you choose from select rooftops.
Now, not every single manhole cover or rooftop will have access to a lair, but there will be a good variety of choices in different parts of each town, so players can actually place their lair entrances close to locales of their favorite gameplay. Once your entrance is selected, that remains your entrance. Exits, on the other hand, are randomly generated in a general area to prevent people from camping it.
