Hi, My name is (Name) and I wanted to chat about the home listed for sale at (Address). Are you the homeowner?
I work with (Company) and understand why you're listing by owner with homes going so quickly right now. Is it still available? How are things going?
(If "great" congratulate them, If not, ask what they're struggling with right now and listen to what they have to say).
I was calling because I might have some buyer who would like to see the property. Is that something you'd be interested in?
(if Yes)
I'd love to set up a time and iron out the details on that, is there a good time to meet? I'd want to see the property and talk with you more about getting it sold.
