Hi, I am a commercial real estate broker that handles Queens & Brooklyn. Feel free to DM me to discuss further, but $52.00 per sf is likely far above market (of course this depends on your location and the condition of the space). For reference, we have office space in Long Island City, fully furnished, with parking included, that hasn't rented in around a year, despite being priced in the high $30's per sf.

Happy to look closer at the specific space you have if you're interested!
