How long does it take for CSB to make a lending decision for business (commercial) loans?
Every situation is different although once we have all of the information needed for underwriting the applicant may expect a preliminary response within two-weeks. The process varies by loan request size and final processing can usually be completed within six-weeks. This requires approval by the bank’s loan committee or by its board of directors.
Does CSB participate in USDA and SBA assisted transactions?
A good place to start includes three-years business federal income tax return copies or CPA prepared financial statements for the company and three-years FIT returns for any individual that owns 20-percent or more of the company. We also ask for personal financial statement(s) for those > 20-percent owners and company accounts receivable, accounts payable and inventory listings. When you are starting a new enterprise (yes, we consider start-ups) we won’t expect historic company financials although well-explained 24 –month projections and a business plan will help. I send new entrepreneurs to the SBA’s website for business plan assistance and to the Michigan Small Business Development Center (michigansbdc.org).
