From page 15 of IRS Publication 535, "Business Expenses":
You can deduct interest on a debt only if you meet all the following requirements.
• You are legally liable for that debt.
• Both you and the lender intend that the debt be repaid.
• You and the lender have a true debtor-creditor relationship.
From the same page:
Mortgage.
Generally, mortgage interest paid or accrued on real estate you own legally or equitably is deductible.
