Law websites like nolo and others have said if the tenant in NJ has made partial payments then you have to give them 30-day notice before you begin the eviction process.

Know and obey the law.

If not, I most definitely would reach out to the tenant, introduce myself and ask if they are going to be out by the 31st or the 1st, I would communicate  to the tenant as if I know they were told they are expected to leave, otherwise you may find they "do not know" they need to leave even if they actually know they need to leave....In the case they claim they are not aware they need to leave, you would need to follow the laws in the state you purchased the property, usually you can find that info on the states judicial branch or speak with a landlord tenant attorney. 

I am doing my best to accommodate and fix the insulation as well as see if there are programs in place to lower the cost. however i want to be firm with tenant as they are not compliant with paying rent because of the cost of the utilities.

I'm not an SME on immigration law, but I know that you can get burned pretty badly if you run afoul of OFAC and AML stuff. 

A lot of the popular areas in Charleston proper that are not licensed under the old laws now require the owner to live on the premises to obtain an STR license.
