Going to call on my first property, what should I ask?

[Tony Iaconelli]

Hey BP,

So my wife and I are currently renting a condo, and I take my dogs for walks around the neighborhood daily. I have been walking by the same condo for over a year now, and it looks like it has been vacant for quite a while. It is not the same complex we live in, but right down the road. I have always thought to my self, whether or not this place is for sale. Well, today on my walk, I noticed there was a sign in the window that said "For Sale, Seller Financing Available!" I took a picture of the sign and am interested in calling on it. I have never done a deal yet so I am unsure of what I should ask. Now I would like to purchase it, fix it up if need be, and live in it and rent it down the road. Or, just fix it up and rent it out, if it has potential to be a good deal. Any tips on what I should say when I call? 

Thanks in advance!
