Inherited tenant legal question

[Andre Taylor-Domville]

Hello all, I have a legal question for a property I’ve acquired with inherited tenants in Brooklyn. The property is a 2 family and both tenants have been in the property for over 10 years with no form of a written lease which to my knowledge places them legally as month to month tenants. They are severely below market and my plan is to present them with a written month to month agreement with an increase to bring them closer to market rents. My question is if they refuse the increase do I still have the option to terminate the tenancy given any legal changes due to COVID, and if I do how much notice is required? I’d obviously prefer not to take that route considering the times but I’d like to know my options going in. Also if anyone has a good landlord-tenant lawyer recommendation it would also be appreciated as this is my first property in the city.
