Growing optimism about the state of the economy was quickly erased with May’s employment report. The disappointing release caused an immediate flight to quality resulting in the 10-year Treasury yield dropping 10 basis points on Friday. The 30-year fixed-rate mortgage responded by falling 6 basis points to 3.60 percent. This week marks the 10th consecutive week the 30-year rate has averaged under 3.7 percent, allowing an extended window for homebuyers to take advantage of these historically-low borrowing costs.
