Freddie Mac, a taxpayer-owned mortgage company, is supposed to make homeownership easier. One thing that makes owning a home more affordable is getting a cheaper mortgage.
But Freddie Mac has invested billions of dollars betting that U.S. homeowners won't be able to refinance their mortgages at today's lower rates, according to an investigation by NPR and ProPublica, an independent, nonprofit newsroom.
Millions of homeowners are finding out that their property taxes are either holding steady or climbing, even as their house may be worth much less. There may not be much they can do about it.
In Ohio, Cuyahoga County's fiscal officer, Wade Steen, has been taking many calls from unhappy homeowners. He says they most often live in a community where voters passed a recent levy. That's a property tax measure that boosts funding for things such as schools and libraries.
Mitt Romney's tax returns and the tax rate he paid on his income have been hot issues in the recent Republican primaries.
"What's the effective rate that I've been paying? It's probably closer to the 15 percent rate than anything because my last 10 years, my income comes overwhelmingly from investments," the GOP front-runner recently told reporters.
So why does a multimillionaire pay just 15 percent on his income? After all, the top income tax rate is 35 percent and many middle-class people pay over 20 percent.
