I was recently made aware of a great new site called Housing Widgets. It is dedicated to real estate related widgets and tools. There is a great collection of tools available for real estate blogs and sites. The site also allows anyone to add a widget for free. If you are looking for new tools to add to your site or if you have an interesting tool you may want to visit the site. It is fairly new so I expect the number of tools available to increase so I will continue to check back often.
