Refinement, elegance and world-class culture define this New York City area. The Upper East Side, long regarded as Manhattan's premier neighborhood. Upper East Side apartments in NYC run from East 60th Street to East 96th Street, from Fifth Avenue to the East River. In the East 60's and 70's, on or near Fifth and Park Avenues, you will find the city's "Gold Coast" - expensive coop and condominium buildings located in mansions and pre-war era buildings. This section of New York City may have the most expensive real estate in the country.
In recent years, pre-war, large white-glove coops have typically seen prices in the $3-30 million dollar range. Go a little uptown however, in the East 80's and 90's, and you can find many affordable apartments just east of Lexington Avenue. Many entry-level professionals and young families buy or rent their first home between Third and York Avenues; an area loaded with amenities and reasonably priced restaurants and supermarkets.
