How to approach off Market deal

[Jared Baker]

Hello BP!

I am very excited to make this post as I might have an opportunity to make my first deal. I found an ad on craigslist about someone looking to retire and sell their duplex. I believe this is considered an off market deal as it is not on the MLS or Zillow that I can see. So I figure I would inquire about the property, but want to know what I should ask. They provided the annual income of $11,100 and taxes of $2714. Eventually I will go look at the property, but it is a several hour drive so I want to get some information before taking the 2 hour drive. So what is information to know before going to look?

Thanks BP
