Not yet addicted to the Multiple Listing Service Web site? Here's a new reason to get on it: There's a new mapping feature where a little red dot indicates -- just like a push pin on a real map -- the locations of houses for sale. It'll take a few clicks through some layers to get down to your desired location, but it's an easy process, and once you're there, wow! Every house listed has a little red dot, and when you roll over it, an info box pops up with a photo of the house and a link to its listing page. Don't like the look of the house on that street? Mouse over to the next street. You can quickly compare house prices from one street to the next or one area to the next. Once you've clicked on each link, you'll get the same listing page with all the same type of info as before. A gentle warning, though: It's even more addictive than the original.
