Owner Selling Portfolio

[Robert Hamilton]

So tonight I was going through Realtor.com and checking out multi-families and come across a listing in which the owner wants to sell two of his properties as a package. While reading the description, it states that the owner would like to sell them as a package if possible; that he/she is selling his/her portfolio. For whatever reason, I check out the tax assessors website on this particular address and find that this owner has at least 50-60 properties. I did count them all. I'm thinking if the owner is selling off the portfolio, this could be lucrative. So, being that I am a newbie, I don't want to sound like a total dunce when I call the broker. Any advice?
