It's true that apartments are expensive in NY, but they're also similarly expensive in San Francisco, and parts of Silicon Valley (Palo Alto).
There's a lot of affordable co-working spaces in NYC if you want some sort office to start, but the most ideal space might be your apartment anyway.
You can also choose to live a little further out of the way if you're trying to save money - like in Queens, Brooklyn, or Jersey City. Depending on proximity to the subway etc, it can be just a 15 minute commute to Manhattan from any of these areas.
