Confusing question about combining live-in flip and STR

[Ryan Cleary]

My fiancee and I are planning on continuing our live-in flips. However, since we are both going to be working remotely, we were thinking about living in our next home from September to January, then traveling in a van for the remainder of the year. Instead of leaving the house vacant, we are purchasing in a fantastic STR market, so we will prepare it for rentals and list it through Airbnb, etc.

Now, I am not sure how this STR income will affect us when we sell the house (completing the live-in flip). I am aware that if you buy a duplex with a long-term rental, you are only able to complete half of a live-in flip, but short-term rentals... I don't know how it would be looked at.
