Weehawken non owner occupied two unit with tenant

[Jimmy Hanson]

Hi I’m purchasing a home in weehawken that currently has a tenant in smaller upstairs unit not renovated. First floor is renovated and vacant. I requested to have property vacant upon closing however the sellers tenant is refusing to leave because he lives in a non owner occupied unit. Is it possible to evict him before closing? I don’t want to lose my mort rate. Can they even be evicted if in rent controlled apartment in non owner occupied? Wondering if I should walk because this seems like it will take forever.
