Is it important for investors to partner with real estate agents?

[Linda May Wacker]

Hi there, I'm brand new - just listening to podcasts and webinars so far.  I'm curious about whether/how investors and agents work together. Some investors seem to find their own deals and just work with realtors when it's time to list if they are flipping properties. I think I am missing something! Can someone describe how they partner with realtors as an investor, and what I should be looking for? Thank you!
