<prompt> Human: Location: NYCBackground: I rent an apartment in an approximately 18 unit building in NYC. I have 3 other roommates and we collectively pay 6000 a month. Some of the units are owned and some of these units are rented out by a management company - this is the company I rent my apartment from. Since I moved in 3 years ago, I have known that the people who own their apartments have always wanted everyone in the building to own their apartment vs. having people renting and always moving in and out. Supposedly the management company had agreed to rent out a few of the apartments for a number of years and then was meant to sell the units at a certain point in time. They have not done this and continue to rent them to people like me. Clearly this does not make the other apartment unit owners happy and now they are in a separate law suit.Main point: Last night, my neighbor they own their apartment called me and told me during their time digging through documents with their lawsuit, they found out that my apartment is rent stabilized and the management companyowner of the apartment that I rent from have never reported the rent they are charging me. They sent me a document from the Division of housing and community renewal that shows that my apartment had the rent stabilized from 1985 to 1994 and then they stopped reporting it. They are now telling me that if I file this complaint with some department myself and my roommates could collect the difference between 6000 and what the rent should have been around 600 for the 3 years that we have been here.The thing is - no one gives out this information as charity. I know my neighbor has an agenda and it is my understanding that if I bring this to a lawyer and there is a legitimate case here that I would most likely be asked to leave my apartment. So the owners in our building would win by screwing over our management company and at the same time have the renters move out.My question is: who do I talk to to verify any of this? Do I just call a lawyer? What are my next steps? I dont just want to be a puppet in this whole ordeal  <response>: Calling a lawyer is never a bad idea
