I did the same move as you a few years ago. I assume your job is in manhattan? Edit: you said jc sorry

I find JC a great compromise between nyc while still having the option to head out from the city fairly easily.

One perk of New Jersey over New York is that you can swapa UK Driving Licence for a NJ one without having to do a road test. This is much quicker and easier. Also council tax here (property tax) is much more expensive (2% of the value per year) and is included in rent.

If you choose to live in New York City you'll pay an additional "city tax" which will increase how much you pay income tax. Worth bearing in mind.
