Deductions & credits

@Anonymous_ 

I have only vacation home. The cases are just for discussion.

 

When you say "You can deduct your refinancing costs provided the property is in service for rental use.",

 

for case 1, the year the refinancing happened had no rental, but the year before and after I rented my house, can I still deduct the refinancing closing cost for the year after refinancing.

 

for case 2, let's say I rented my house for the first 7 months and in the 8th month, I did the refinancing, can I deduct the refinancing closing cost the this year?

 

Thank you very much!
