You'll have a lot less space than in Tennessee. For the same actual quality of living, you can expect to pay far far more, and in many cases, it may not be possible at all (you simply can't get decent single family homes around NYC without a long long commute).
From cost of living calculators, Manhattan is about 25% more expensive than the other most expensive places to live in America (Boston, San Francisco, Los Angeles, etc.), though the outer boroughs aren't as bad.
