Yes you do, undoubtedly someone with more tax experience will give you better information than I will, but yes, 10k in mortgage interest will be 100% tax deductible from your gross earnings.

In order for this to be realistically beneficial for you, the combination of the mortgage interest along with your other deductions such as state income taxes and childcare expenses and -- what is the third major deduction people take? I'm drawing a blank.

Those deductions need to be larger than the standard deduction the IRS gives you, whether you are single, HOH, or married. If you paid 10k in interest, then it will likely work out for you, as this amount is larger than the Standard deduction for any type of filer.

p.s. Property taxes is the other deduction I think is applicable here.
