Even if the "Houses, Condos" etc. icons are supposed to work in the future, I think they're too huge and don't really add anything visually.
When I search for a rental, I think the map takes up too much space. I think I would prefer to decide which results to focus on based on the information returned first. The search results page kinda pisses me off because I can barely see the first result since it's taken up by this gigantic search box with so much space around the "Filters" drop-down menu.
On the "Browse Rentals" page...what's the purpose of this page? Why should I want to browse all the rentals available on your site when I'm only interested in some locations I have in mind already?
Otherwise, I think it is a good idea since people might start renting more and would like to know what they're getting into beforehand, but the site just looks really busy right now. Too many different colors; you have a million different shades of blue for example.
