I lived in NYC about 17 years ago and the whole idea of "lofts" was a movement to gentrify old brick factory buildings downtown by housing artists inexpensively.
More recently, here in San Francisco, this "loft" idea, which features live/work zoning, was a building style that took advantage of light industrial zoning to build residential units - and make a profit for the developer. I have looked at buildings such as 200 Brannan, when some are advertised as lofts, and others as condo, on the mls, and I see little difference in sales price. Most "lofts" in our City are condos (which are simply a form of ownership), with "lofts" being a type of layout of the unit. As Jed has pointed out, there are buyers who love the loft layout, and others who prefer a "separate bedroom," that point out a weakness in the loft floor plan for families. Think of demographics ... we're a City with lots of young workers at the moment who do, perhaps like yourself, enjoy the City *loft* lifestyle. Location will trump your loft question.
