Freddie Mac's results of its Primary Mortgage Market Survey® shows that "The uncertainty and volatility in financial markets is heavily impacting mortgage rates. Our survey indicates that the range of weekly rate quotes for the 30-year fixed-rate mortgage has more than doubled over the last year. This means that for the typical mortgage amount, a borrower who locked-in at the higher end of the range would pay several hundred dollars more than a borrower who locked-in at the lower end of the range. The large dispersion in rates means it has become even more important for homebuyers to shop around with different lenders."
