Is pursuing a duplex a lost cause in this area?

Furthermore, I fortunately had a visit planned to the US right around closing time so I was able to have everything notarized there.

Denny Crane Never Lost Never will.   

You also need to accommodate tenant schedules for showings.Relisting later might reset your listing's visibility, but delaying could cost you more in lost income.

Indian Rocks Beach amended their law quietly and someone caught it and they lost their whole entire law.Hillsborough County passed an (illegal) 7 day minimum in 2017 (or 2019 I forget) and they do not enforce it. 

If thats the case, I am afraid they get delayed or even lost in the mailing.

This amounts to lost opportunity because if you had purchased RE, at the closing it can start producing return. 5) ADUs detract from the existing structure whether this is privacy, a garage, or just yard space. 6) this is related to number 1, but there are many more buyers looking to purchase homes for their family than there are RE investors looking to purchase small unit count properties.

This buyer's agent and I are working towards the same end goal, fortunately.

He also lost his licenses in Arizona.

I thought all was lost.
