Rates change daily and sometimes more than once a day. They are dependent on term, you didn't indicate, down payment, you've got 20%, your score, 740 mid score usually qualifies for the best rates, the loan balance and the fee structure work out with your lender. Fees can be paid in cash or offset by a slightly higher rate. You can buy down a rate below market average or pay above market average and have lower fees.
Bottom line rates are outstanding, but more complicated than just quoting a number. Talk to two or three lenders with your specific requests to get a good feel for who will take the best care of you and give you an attractive price.
