Calculating savings from mortgage interest deduction vs. standard deduction?
Those choices aren't mutually exclusive.  Yes, most discussion of the mortgage interest deduction ignores the fact that for a standard itemizer, much, if not all of this deduction can be lost.  For 2011, the std deduction for a single is $5,800. It's not just mortgage interest that's deductible, state income tax, realestate tax, and charitable contributions are among the other deductions. If this house is worth $350K, the property tax is about $5K, and since it's not optional, I'd be inclined to assume that it's the deduction that offsets the std deduction. Most states have an income tax, which tops off the rest. You are welcome to toss this aside as sophistry, but I view it as these other deductions as 'lost' first.  I'm married, and our property tax is more than our standard deduction, so when doing the math, the mortgage is fully deductible, as are our contributions.  In your case, the numbers may play out differently. No state tax? Great, so it's the property tax and deductions you'd add up first and decide on the value the mortgage deduction brings.  Last, I don't have my mortgage for the deduction, I just believe that long term my other investments will exceed, after tax, the cost of that mortgage.
