A reader asked: "I’m moving out of my rent-stabilized apartment in Brooklyn and I provided my landlord with a suitable replacement, a friend of a friend who needs a new place after ending a relationship. When I told my landlord that I needed to end my lease early and that I had a replacement for him, he responded that it would be fine as long as she worked with his broker. His broker is charging a large fee and asking for a guarantor that makes 80 times the rent. Is 80 times the rent typical And why would she have to pay a broker’s fee here"
