@Whitey - They go off our website when they go under contract. Once they go off they will never return so we serve a 404 page. They aren't necessarily replaced but anytime a new listing hits the market, they are added to our website. A lot of churn with our pages, and currently we have 5,000+ errors in WMT due to these pages.
The feed is called an IDX and it's provided by an MLS. MLS's are controlled by Realtor's and the only way to access this data is to be a Realtor, or like the big real estate websites, they have to pay an enormous amount of cash for the feed.
Just for our feed in my state that covers about 20 counties out of 28 counties, it costs us $6,000 a year. Plus we have to pay an additional $200 a year to pay auditors to check our site once in a while for compliance.
The long standing content we have on our pages are city/county/neighborhood pages. Each of these pages are designed for one or two keywords, but the listings that sit on those pages recycle out a lot.
