Inspection cost? and do you need them

$600 - $1,000.

And yes, an inspector should look at new builds as well as old. If you're willing to pay $400K, or $500K, or way more for a one bedroom, you're foolish not to invest the $750 +/- for an inspection. And follow the inspector around - you'll learn a great deal about your building in particular, and things to know about/look for in general.

I would never think of buying a single family home without an inspection so I guess, yes, it's probably a good idea for an inspection on an expensive NYC property, too. Yes, accompany the inspector & carry a flashlight & a legal pad & pen, too, for notes. You're paying for it, don't miss a thing!
