You state that you must display the full name of (up to 4) tenants and the full address of the property. Must this information be displayed at all times, or only when the user is making their selection?
If the full information that you described need only be displayed when the user is making a selection, then abbreviated information might be used in a list (perhaps with radio buttons), while the full information might be visible with a mouse-over. If it can be used, abbreviated information should be distinctive enough to at least give the user a "hint" so they can discriminate somewhat between choices and confirm their choice via the additional "mouse-over" info.
It would also be possible to display the full information of the chosen option, once selected, and abbreviated information about the remaining options, with the full info being available via mouse-over.
