In the world of NYC real estate, the term “affordable” is all relative. $575,000 for a one-bedroom apartment isn’t cheap by any means, but in New York, it is a good deal when we’re talking about a prime neighborhood of Manhattan. Cue this co-op apartment now up for sale at 173 East 74th Street on the Upper East Side. It’s a half-block from Lexington Avenue and three blocks from Central Park. While it isn’t a huge apartment, it’s well-kept and just spacious enough.
