Buying a Duplex as a second/vacation home

[Dewayne Lanier]

I am thinking of purchasing a duplex as a vacation home in another state. First, can I do this? Second, can I rent out one half full time and Air BnB the other half when I'm not using it? Also, is this type f property subject to the same 2 year owner occupied restrictions when selling the property to avoid capital gains? In other words could I sell this property after 2 years and avoid cap gains tax without doing a 1031 exchange?
