Hello expert advisors, I have a 3 family home in Union City NJ and have a very crafty tenants. They moved in in November 2020 and since then have never been able to pay rent. However, they have received multiple forms of rental assistance from the city/state/feds. Currently they are receiving rental assistance from the CARES Act. I receive the rent 4 months late but nonetheless, it comes in in chunks. I am less concerned about the rent but more about how crafty and authoritative this young couple is, I am trying to evict them but because of how friendly NJ is, I'm unable to do so, here are the following areas they are in breach of the yearly lease:

1. I had given them a payment plan to pay security deposit in three parts on move in, they paid the part that was required before move in but not the remaining two

2. They smoke in the house, however - I have no "proof" to prove that they do in the court of law except that I smell it and see a cloud of smoke arising from their unit every time I enter

3. They stated there would be 4 persons living in the unit and we have 4 names on the lease, however - how they've added two more adults - an ailing father and a child from maybe another parent they have custody over

4. The man is authoritative, rude and always talks with attitude when I want to discuss anything with him, nothing ever reaches commonground due to his tone and approach

5. I had given them a Notice to Quit back in august because we decided to go move in into that unit, but they called and let me know they "wouldn't move out so easily" and asked to take them to court

I am in such a difficult mindspace and need assistance here. Anyone, anything? I really need them out.

Thanks in advance!
