Mortgage rates tend to fluctuate day by day. So if you’re planning to buy a home, it’s a good idea to keep a close watch on interest rates and weigh various mortgage options. One common type of mortgage is a conventional loan with a 15-year fixed interest rate.

The Mortgage Bankers Association predicts that mortgage rates won't change much over the next three months. The trade association forecasts that the 30-year mortgage will average 6.8% from July through September, about the same as the average from April through June.
