The very fact that a second "Sex and the City" movie exists is proof that the lessons of the sharp economic downturn -- both in Manhattan real estate and, um, everything else -- haven't totally sunken in with everybody out there. But while it's usually not a good idea to look to NYC real estate for signs of rational, level-headed thought, a recent poll by the National Apartment Association indicates that perhaps those looking for Manhattan rental apartments have internalized the lessons of the economic demi-disaster better than, say, whoever green-lit "Sex and the City 2: The Grievous Miscalculation." The NAA poll finds that 76 percent of people prefer to rent apartments, as opposed to owning them. That's a five percent increase since 2008, and it is, in its way, kind of heartening.
