They had just had a pre-inspection the day prior from 10am-5pm and many walk throughs of their home.

It's cake walk after you go through the process. 

I want to do a full renovation and wanted a construction property manager to walk through the property with me and let me know of any major work that needs to be done.

I am looking to purchase my first duplex or quite possibly a single-family home with a walk-in basement for a house-hack. 

@Shion Queen the best is to visit the places you are looking at if you walk down the street and fear for your safety you don't want to invest there, think of your area, there are probably locations you wouldn't want to invest, these agents are thinking like that and trying to give you good advice, but without a frame of reference you feel like you aren't getting a full picture.

Bought it for $95k off market, planning to put in about $43k and sell for $190k.We walked through twice and the seller told us there was no basement and no crawl space. 

If you are new and have never ran a company before, I definitely recommend having a lawyer set up you first LLC, and have them walk you through all the necessary steps to maintain full protections. 

My wife and I are thinking of converting the carport to a master bedroom with a master bath and walk-in closet.

Learning to properly examining title takes time and experience, you can't just walk into a title plant and start examining title, and being an attorney doesn't give you a leg up. 

One thing you might add to your list of "to do's" is create a "Walk Through Form" for the tenant to sign when you give them possession so down the road there are no disagreements over the condition of the property when it is time to disperse their security deposits when they eventually move out.
