Your site has a nice, clean look to it. More important, it does not look like a typical cookie-cutter site. Congrats on that one!
Navigation wise - it's easy to get around your site. Menus are clear and for the most part intuitive.
The one thing that jumped out at me was that I have no idea where you are selling property. OK, if I really look hard I can see that you're in CA.
From an engineering standpoint, you should take the time to
validate your HTML . When you validate you HTML and
validate your CSS it helps to ensure cross browser capability (although you may still need to tweak or hack your CSS).
From a content standpoint, there really is no content. Your site does not give me any insights to the communities that you service. Sure, there are outbound links - but that takes me away from your site. Now, if you had content with
your insights, that helps to let me know that you are a real estate expert in your area.
SEO wise - the site will not rank well or garner search engine traffic.
You have made a good start on your site.
