Question
Can you deduct mortgage insurance premiums on rental property?
Answer
In general, you can deduct mortgage insurance premiums in the year paid. However, if you prepay the premiums for more than one year in advance, for each year of coverage you can deduct only the part of the premium payment that will apply to that year. Report the deduction on line 9 of Schedule E (Form 1040 or 1040-SR), Supplemental Income and Loss.
