Deducting mortgage interest for primary home with secondary unit rental

Hi, my wife and I have a mortgage for our primary home which includes a secondary unit on the property that we short term rent. The secondary unit is managed by our LLC which in turn pays us a lease fee for the secondary unit. How do we handle our mortgage interest deduction? Does a portion of the interest get assigned as an expense on Schedule E where we list the lease income from the LLC?  Do property taxes work similarly?
