Requesting further Info from RE Agents and owners

[Steve Burt]

Hi all, in about 6-8mos time, I will be investing in my first property. Likely a small SFR for my brother to live in while at college just to get a feel for the buying and PM process. That being said, I will have the capital to potentially acquire something larger. It would be tremendously valuable to me if I were able to contact realtors now get some info on properties (income statement, rent roll etc) and then analyze them. I would then be able to see what they sold for and get some practice in before gearing up for the real thing. My question is would Real Estate agents be willing to allow me to sign an NDA and get these docs? I don't want to indicate buying interest because as of now that is not likely and I of course value their time.
