This article Using Tumblr.com as a Single Property Website led me to a *duh* moment. It mentions using blogger.com as a way to have a unique URL for every listing. I already have two blogs on blogger.com, so just added a third one – all of them are free.
So my 38 acre listing in Monroe now has its own web site at http://woodscreekpreserve.blogspot.com/
Look for the Eco-Chic Cottage on Meridian blog page soon!
