Project the Income Tax Consequences of a Refinance or Property Tax Appeal
Homeowners everywhere are working on applying for a lower property tax bill on the basis of the last few years' decline in their home's value. Those who have equity have flocked en masse to refinance their 7% home loans into the 4% to 5% rates of the last few months. These strategies offer some of the heftiest household savings out there for the corresponding investment in time and money they take. But here's a caveat for savvy homeowners who slash these costs: remember that property taxes and mortgage interest, the very costs you're minimizing, are also the basis for the major tax benefits of being a homeowner. So plan ahead for your income tax deductions to go down along with your taxes and interest.
