Vacant home, owners passed away, may be in probate? How to make an offer?

[Emily Snapp]

I am a new investor, haven't even purchased my first property. I found a home in a great neighborhood that is vacant. The neighbor was out in the yard so I stopped and asked him about the house. He said it's been vacant for around a year, the elderly couple passed away. He said the kids keep the grass cut and thought the home might be in probate. Some of our counties records are online but not probate. How should I proceed? I'd like to find the owner and make an offer. The property is in Spartanburg South Carolina.
