I’d love to see ZipRealty and Zillow merge. All the information could be integrated into a single report. For example if a buyer knew that a seller was underwater and the house’s been sitting for 180 days, he could make a better educated guess on what to offer. Also, if a person could see all the listings as well as all the sales in a neighborhood, that person could better determine the value of a home.

I understand that this information is available now, but an inexperience lay person may not know how to access it all. A single source of info would be great for the consumer.
