Tired of being outbid on every Manhattan apartment you are interested in buying? Well, things are looking up. Overall, new home sales since Labor Day have been brisk in New York City. Openings of new luxury homes are already bustling this fall, and more supply means buyers are feeling less pressed to jump on a purchase than they may have been earlier this year. And with new supply on the rise, it seems many previous would-be buyers are now saying 'so long' to their rentals. But with the housing situation improving, purchasers may have a small window of opportunity to take advantage of still ultra-low interest rates.
