OOS "walking a property"

[Josh Raikin]

New to investing and looking to invest Out Of State (in CA, looking in OH). I found an amazing real estate agent to help me who is in the city I'm looking to invest in, but just read chapter 13: "Walking a Property-- what to look for" in the Multifamily Millionaire Vol 1, and it didn't address the best way to do so from out of state. 

If I'm unable to go to the city I want to invest in, what steps can I take to get to know a property as well as possible?
