How to approach a seller directly when property is on MLS

[Zachary Harrison]

I have come across a property that I am interested in that is currently listed on the MLS. From the county assessors website it appears the property is own a by trust. I found the potential members of the trust and am curious as to how I should reach out to them in regards to the property.

If it would help any it looks like a widow (late 70s or early 80s) and her kids are members of the trust and some of them live in the area.  Thanks and would love to hear different opinions.
