Resultly is a website and mobile app for streaming results. Resultly allows you to follow virtually any interest you have from across the internet and be notified in realtime of new information or changes about your interest.
Resultly makes it possible to look once, and never look again. By adding something to your interest list, you can be notified, literally to the minute, as soon as something is posted on the web that matches your interest and the criteria you specified. It of course works not only for housing searches but many different categories. It also takes into account your location and social graph.
