There are signals that mortgage interest rates will go up in near future. Leading indicator for this trend is increase in yields for mortgage-bonds issued by Fannie Mae and Freddie Mac. Upward trend is quite strong as it is persistent since last five days.

On a $300,000 mortgage, the principle and interest payment, at today's average rate, would be about $1,594, compared to $1,825 a year ago, according to Erate's calculators. http://bit.ly/RK4nU
