I agree with MVP in that it is pretty easy to eliminate the querystring from your pages by using inheritence. We had originally designed our pages to each pass an ID in the querystring but then realized that this didn't go over very well with the search engines. We spent a day or two and set it up so that we have a separate page for each of the hundreds of properties listed on our site but we actually only have one set of code behind the scenes that generates all of these pages. Whether or not it will actually help to not have the querystring in the URL is anyone's guess - but it doesn't hurt to get rid of it.
