While not free, the component is overall worth the cost, considering the included support and unlimited licenses.
The component is easy to install and manage. Feature-wise, it has lots of details you can show for a real estate, which is nice. :) Beyond the poor Italian translation (which I improved), the component may see a few welcome additional features, such as a global map, a city selection dropdown, and especially full titles in each page (category/estate). The only real remark is that the search plugin, t least in the Pro package, should be included and not an add-on cost.
I've been in contact with their support team and it's been a pleasant experience: always polite and open to new ideas. :-D
With my background of Joomla! 1.5, working on this 2.5-ready component has not been a problem at all.
FW Real Estate is a good component.
