I am thoroughly excited to explore each response given to me, and the options you all have presented.

I did a thorough inspection and walk through of the property and tested everything 2004 build in excellent condition.

I would examine a particular neighborhood thoroughly, in research and on BP with other investors before you enter either of these markets.

Also not everyone who buys a duplex is an investor, some people buy them to live in and reduce their living costs without ever planning to do a house hack or crunching the numbers thoroughly. 

Trying to be extremely thorough, and maximize my success for my first go.

However, there are a couple ways to get around this.Depending on how long your lease is, I would do a thorough walk-through of the property in between each lease.

I would start by hiring a home inspector to do a thorough inspection.

When we complete similar deals for clients we'll be able to look at what rent they should expect along with any rehabs that will be needed prior to rental and have a more thorough timeline than if they were using separate entities for each. 

@Alexander Schloe a key item is I always have a very thorough partnership agreement mapping out to the n'th degree.

I know now I overpaid for the property and my due diligence process was not thorough enough.
