Spurring Business in Communities Act of 2017 (Sec. 2) This bill amends the Small Business Investment Act of 1958 to: require the Small Business Administration (SBA), in reviewing and processing a small business investment company's (SBIC's) application, to give first priority to an SBIC applicant located in an underlicensed state (i.e., a state in which the number of licensees per capita is less than the median number of licensees per capita for all states) with below median financing; and exempt applicants in underlicensed states from certain SBA capital requirements.
