Do I ask the realtor on Craigslist for a full listing?

[Dylan Hagen]

I was on Craigslist looking at multi family properties to do a possible 1031 exchange with.  I saw a duplex that I wanted more information on so I sent an email.  A realtor replied and answered my questions.  She also said she could send me a full list of multi-family investment properties for sale.

My question is, do I get a full listing from her?  What if I don't use her as a realtor?  I am new to this and don't want to do anything unethical.

Thank you,
Dylan
