I flipped a house that sold in 2020 as an investment property. Do I include the interest paid on borrowed money as part of the "cost basis" for the house? Or do I deduct it as investment interest Expense?

    No, mortgage interest CANNOT be added to the basis.

     

    It would be deducted as a business expense. 

    (There are no deductible "investment" expenses)

    Your house flipping should be reported as a business, thereby allowing you to expense material, labor, and the interest.

    Kris,

    I held this property for over 1 year and since it is my only flip I thought I would benefit from LT Capital Gains treatment as an investment. Wouldn't the cost of rehabilitation, materials and sub-contractor labor plus closing, attorney fees and realtor fees all go into the cost basis for the resale?

    Filing as a business would subject me to regular income tax and self employment tax, correct?

     

    What am I missing?

     

    Thanks

    A business with income would trigger the SE tax. This is not a business in your opinion, it was just a flip. The IRS may disagree with you. See Earning side income: Is it a hobby or a business? 

     

    Here are the options if not a business:

    • Mortgage interest is deductible on Sch A for your main home and a second home. If used as a second home.
    • Mortgage interest is deductible as interest paid on a business return.
    • Investment interest, see What Are Deductible Investment Interest Expenses

     

    The property was held over a year, long term gain.

    As for the basis, the cost to purchase plus improvements plus cost of sale all add together.

     

    The IRS does not allow a deduction for mortgage interest paid in the basis.
