There are many different credit account types your business has the ability to maintain. These include, but are not limited to, real estate loans, auto loans, equipment loans, credit card loans, etc. While some types have bigger impacts to your credit score than others (i.e. Real estate loans), it is important that you maintain a mixture of different types. This shows potential lenders that your business is capable enough to manage multiple credit accounts. Also, try to limit the amount of loans to each type, such as limiting the number of real estate loans.
