Getting a retail loan for a business requires an acceptable personal credit score. A low credit score caused by late payments and high personal debts can disqualify you for financing. On average, commercial retail lenders look for a credit score 680 or higher. Some lenders may approve you with a lower score. Regrettably, the lower your personal score, the higher the interest rate on the retail loan. A higher loan rate can greatly increase the retail loan payments. Cleaning up your credit first and then applying for financing not only helps you qualify for financing, but also helps you qualify for a favorable commercial interest rate..
