<prompt> Human: Asking for my older co-worker who just accepts it...She says this year her landlord increased it 2X this year, once 100 and the other time an additional 150  <response>: Unless its a rent controlled apartment , Its their house they can charge whatever they want. They have to honor the current lease until expiration but when a lease expires they have the right to not renew it, renew for the same, ask for double ... The market dictates the rules not any laws
