Renting Out Primary Residence for Less Than Half the Year

[Zack Friedenberg]

I recently purchased a Condo in Summit County, CO as a primary residence. After purchasing the Condo, my Fiancé and I decided to keep our Denver rental and split our time living in Summit County for a little more than half of the year. 

Am I able to rent my Condo out on Air Bnb for the 40% of the year that I will not be living there? Fannie/Freddie guidance on what constitutes a primary residence is the "majority" of the year owner occupied which will be the case. This seems like a grey area and I have gotten mixed guidance on how to proceed. Any advice on the subject is appreciated!
