In mid-April, mortgage interest rates on 30-year fixed-rate loans increased to 5.21 percent, an eight-month high and a reminder that low interest rates won’t last forever.

Interest rates are expected to be higher at the end of 2010 than they are now, perhaps in the 5.5 percent to 6 percent range, according to sources like Fannie Mae and the National Association of Realtors. Between now and then, rates are likely to be volatile.
