rentslam.com lets you be the first to respond to newly posted listings. Being one of the first people to view an apartment helps you find the best deals as soon as they go online. The apartment I now live in was posted the same day as I did the viewing and it meant the number of candidate tenants I was competing with was quite small. My Colleagues were surprised I found an apartment so fast and I do not have to feel like I settled. Thanks RentSlam.
