1) was personal use of the property more than the greater of (1) 14 days or (2) 10% of the days rented?
Any day rented to anyone at less than a fair rental price is considered a personal use day. Any day rented to family members is a personal use day unless fair rental is charged and the unit is the family member's main home IRC Sec 280A(d) (3)
I'll assume the answer is yes then the next question
2) was the property rented less than 15 days? Any day rented to anyone at less than a fair rental price is considered a personal use day. Any day rented to family members is a personal use day unless fair rental is charged and the unit is the family member's main home
I'll assume the answer is yes. since both are yes the IRS says this is a second residence. taxes and interest go on schedule A. There is a cap on mortgage acquisition debt
