Check out TheRentables.com
I was shown a promising new site called TheRentables, for people (I know at least 3) who are looking to rent an apartment. They say:
"The Rentables takes a fundamentally different approach to rental property listings to deliver the most relevant, accurate and comprehensive housing information to anyone at any time." (from About TheRentables)
I looked in Brooklyn, New York, and there were no listings (they are in the very early stages) But in Boston there were some listings. The site looks useful. Now the trick is to get landlords to enter their information.Technorati Tags: realestate, therentables, startups
