2. Your landlord might be charging you illegally high rent
If your apartment is rent-stabilized, your landlords cannot charge you whatever amount they pull out of a hat and multiply by two. They can only charge you the legal regulated rent, which is set so that living in New York City is not exclusive to hedge-fund-droids and finance-bots. This is what makes rent-stabilized apartments so great. You can figure out what your legal regulated rent is by going to DHCR and checking the rent history register. If it’s lower than what you’re paying, you are being overcharged.
However, some New York City landlords have the cunning of hungry rats, and might register fraudulent rent with DHCR. There are ways to determine if the registered rent is fraudulent, but the analysis is a little complex. A rent-stabilized landlord can only increase the rent under certain circumstances, for example, when a new tenant moves in, when an existing tenant renews the lease, or if the apartment is given a major renovation.
