Via zillow.com Mortgage rates first started being tracked in 1971. Since then, they have ranged from a high of 18.63 percent in the early 80′s to a low of 3.20 percent in late 2013. Currently, rates are still relatively low and for many prospective home buyers, low rates can greatly affect the affordability of a home and the monthly mortgage payment. However, the low-lows of the 2010s are not expected to hold out for long. "Federal Reserve has announced plans to begin winding down its stimulus program, which has helped keep rates low while the economy was still fragile, we expect rates will rise above 5 percent in 2014 as the economic recovery gains steam," said Erin Lantz, director of Zillow Mortgage Marketplace.
