FlyRig.com is a reasonably new (launched very late last year) NYC apartment rental listing service. The site has some of the best google maps API implementation i’ve ever seen.

After selecting the area you want to live in (Manhattan for example) you’re taken to a page clearly listing information on the different properties in that area. When you mouse over the different apartments google maps smoothly zooms to the apartments location on the map. It’s a wonderfully clear and concise way of looking for a place to live.

We’re trying to improve the rental process here in New York. The tight market
results in misinformation and opportunities for unscrupulous agents – things
that are frustrating to both renters and agents who work hard to build trust
with their clients. In addition, there lacks a modern solution for finding
apartments in the city – the most popular listing services either lack mapping
capabilities or supporting information commonly needed when deciding on a place
to live.

FlyRig was self funded by Adrian Liang. He works on the site full time along with one other part-time employee and two occasionally used contractors. Since launching in December 2007 they’ve signed up over 250 brokers from some of the largest agencies in the city.

It’s a really nice little service. The system could presumably be expanded into other cities without too much effort.
