I like your Mortgage Market Place idea. People need real appraisals for personal reasons, not just mortgage lending. Is it possible for Zillow to offer real appraisal services?
I believe it is a natural for Zillow to be the front end of a "comp check" for value. However, lenders will not accept Zillow values for lending purposes. Lenders are rescinding home equity loans because of declining markets. To challenge that, an appraisal is necessary.
