Mortgage refinance rates are not the same as purchase interest rates. Generally, mortgage refinance rates will be slightly higher than purchase interest rates because a refinance is considered to be of slightly more risk to a lender than a purchase. In addition, there is generally a difference between mortgage refinance rates—a cash-out refinance will generally carry slightly higher rates than a regular refinance. Mortgage refinance rates are also determined by one’s credit score, debt-to-income ratio, geography, loan product, unit type, and loan-to-value.
