Pick listings for a client, add a comment to each and send one link. You see which homes they like.
In search results or on a listing page, press the list button to add a home to a selection. Add a word about each listing and send the client one link under your name.
The client marks each home Interested or Not for me and can comment. You get an email when they answer and see a counter in your dashboard. Selections also have a table view and a CSV export.
