There are longer version examples available from some of the yellow letter companies, but I don't think you need to go into too many details on why you are mailing them, or being compassionate for their loss(that should come during the phone call if they tell you why they are interested in selling).If they are truly motivated they will contact you from a relatively basic letter, and that may be a better way to approach someone in this situation than an email or phone call if they are still grieving.

Once you've exhausted those avenues, then find a small balance commercial broker that will close it.
