Lenders can’t answer that question directly. Good credit is great but we need the specific score, we need the loan program, we need to know how much down, and what your debt ratio is. Right now it could be anywhere from 3.5% to 4.25% for most fixed rate programs.
I have investors that don't use a credit score for your rate. So if you have good credit you may get the same low rate as someone with excellent credit. I've seen a 580 score get the same rate as a 760 credit score. This investor may be right for you.
That is too general of a question. More info is needed, such property type? Down payment? Occupancy, to name few along with have "good" credit. Feel free to contact me for a no obligation mortgage consultation.
