I am curious about something that came up in this question: Can a realtor show my apartment at will, with notice?.
In the linked question a comment for an answer states: "The realtor IS the landlord due to being the landlord’s agent - it’s highly unusual for a landlord to attend a showing." I understand this comment to mean that both the management company representative (the person who fixes things here) and the realtor are the landlord's agents. I.e. both have access to the apartment with or without consent, and the later can bring in third parties (prospective buyers).
Can the property owner/landlord (in general, not just in my case) appoint representatives at will, who will have access to the property they are leasing out? Or is there a definite legal definition of a representative and how they are appointed?
