I think given Jackson Heights' demographics and the high percentage of immigrants who likely also have higher ownership rates, the neighborhood will not change at the same pace and in the same dramatic fashion as, Brooklyn, for example. At least I hope so anyway.
One of the reasons why I decided to move here, in addition to the convenience of transportation, square footage and layout of apartments for the $, is that it is truly a very diverse neighborhood with access to South American, Southeast Asian, South Asian and East Asian groceries and restaurants. And I think if they need to raise prices to sustain a living, so be it, I would think people who can afford to pay more than half a million for an apt can afford to pay more a few dollars more for an entree especially if those same people happily pay $30 for glorified adult Lunchables (charcuterie).
