First time homeowner - Buy duplex without seeing both units?

[Andrew Bissada]

I am looking into buying my first property to house hack. I am looking at both SFH and Duplexes. I like that I could have privacy with a Duplex(live on one side, rent out the other), but it has its own challenges.

One thing I am wondering about: How common is it to buy a duplex after only getting to see one of the two units? AND not having pictures(or only having pictures of one of the 2 units)?

It seems like there are a lot of cases where one unit is vacant, and they have pictures of that. But they have no pictures of the occupied unit. If the vacant unit is remodeled, then I don't actually know what the occupied unit looks like/what condition it is in.

To me, at a minimum if I can't see the unit, I should at least be able to see pictures for both units. This is a big decision and I want to be as informed as possible. 

What are y'alls thoughts? Do you agree with my thinking, or are there details I am missing for why I shouldn't worry?
