Made an offer, but starting to worry

[Michael Kim]

Hi everyone

My first time posting! I live in the SF Bay Area and would like to get into real estate investing for cash flow, and am targeting Indianapolis. That's where I'm from so I'm familiar with the area. 

I found an investor who has 3 properties and is wanting $60k for them each. I offered $50k cash for all the properties, contingent upon bank statements, lease agreements, maintenance history. Seems like the homes are already cash flowing at $750 per month each. I haven't heard back from the seller or broker yet. 

Questions: I'm not being represented by anyone, should I look for an agent who can represent me in these dealings?
