What to Ask the listing agent for Duplex

[Jared Baker]

Hello BP.
Easy question for you all.  I am scrounging realtor, zillow, and other listing sites to get an idea of the market.  I want to contact the listing agent to get a better understanding of the listing because not all the information is always there, so when I contact them, what are key pieces of information that I should ask about to make sure I will have a good understanding of the area.  One thing that I have heard from other sources is ask for the trailing 12 (if I am understanding that it is the last 12 months of income/expense reports), is that something to ask the listing agent on a duplex?  I would like to find out what the current owner is renting the units at and the expenses that are accurate so I can evaluate on actual numbers and not guessing.

Thanks BP!
