I was promised a low interest rate of 1%-2.5% as a widowed disabled woman, on my purchase of my home in 2008. First bill came. Rate was above nation average @ 7.75%. And every year my house payment is increased. Why? My personal credit has always been high/Very good 730+. I feel used. How can I get out of this USDA mortgage? In ten years @$423 + I have only received 1,000 a year off my balance.
