Guidance for "pitching" a decedent' family

Hi, 
I got a lead on a property today for a vacant home. The homeowner died and the children (older adults) have ownership but haven't done anything with it. What would you suggest is the best way to approach or "solicit" the owners while still being empathetic to their loss of family member? Does anyone have an example of how they approached this scenario? 
The current owners have a local business and I had thought sending a personal letter directly to the business might be a possibility or researching where they live and sending letter directly to their house (which seems a bit stalker style). I appreciate your thoughts and suggestions for this. Thanks!
