Last two times I moved, I have found that once properly informed about BPs(max size, usual temperment, legality according to by-laws, housing and it's security, feeding habits aka dead rodent only for me, etc) all landlord except one had no issues at all. Most were neutral at the prospect once they figured they were harmless and would not damage their property or cause legal problems, it's when you start being less then honest that we end up as a hobby with a less then perfect reputation.
