Strategy for a Noob

[David S.]

Hi all,
I'm new to REI. I want to try investing with a subject-to strategy and hold the property for rental and long-term appreciation. I came across a multi-family (2 possible 3 with some work) that has 2 mortgages on it. The person is represented by a realtor, and I assume once I throw around terms, the realtor might get nervous and not deal with me. They also might not be willing to share how much is owed on each mortgage. What is the best way to go about obtaining this information. I don't want to waste 3 hours of my time going to see the property, etc... if i can very quickly assess if this deal is at all possible with some questions. How would you approach this with a phone conversation or email?
Thanks for your help. This is a geat forum.
