My first reaction as well. Secaucus and Rutherford fall squarely into the “nothing to do” category, not just Palisades Park. Does not sound like your realtor knows what they are talking about.

As a young woman living alone for first time after college on 57k, I’d lean more towards the Heights or BL with roommate(s) than JSQ alone though. A better realtor can help with this.

Also consider getting a bike for transportation.

Edit: yes, 30 is young!
