Mortgage rates hit the lowest level in decades for the seventh time in eight weeks. The average rate on a 30-year fixed mortgage was at 4.44 percent last week according to Freddie Mac. Some homeowners have refinanced for as low as 4 percent. For homeowners with solid finances, the opportunity to refinance below 4 percent is attracting some to consider a 15-year fixed loan. The average rates on a 15-year fixed loan dropped to 3.92 percent last week as well. More homeowners are choosing this option because it allows them to save more money in the long run, even though their monthly payments will be higher. According to Freddie Mac, almost a third of refinances from April to June picked 15-year or 20-year loans.
