When I try to make any changes to a listing, on any computer, I get a red message saying: "there are errors with your submission please see areas marked in red below", and the "additional remarks" section shows with a red box around it, and a message in red appears under the box saying "You must enter no more than 100 Characters for null" and then I have to delete all the extensive MLS listing information in that box before I am able to save my open house or other modificaton to the listing. This takes a lot of time to scroll through and delete, PLUS presumably I am now deleting all this info from the listing. After deleting the info, I am allowed to save my changes. It is extremely annoying, cumbersome and non-functional. Zillow has been no help, even though as a customer of zillow, I pay about $1000 a month.
You are most likely to get a good offer if you price the home at or slightly below the current appraised value.
