Part-time "small business owner" impact on the loan?

It was the current account at Netbank. The Münchener Hypothekenbank wanted to know why there is an account there. This is only to separate the regular income and household from the small business. It is a free business account.

Question from the bank:

"
- According to Schufa of Mr. XY, there is a "business current account (for self-employed and small business owners)" - is there self-employment here?
"

Well, you have no self-employment and during routine checks the bank finds a business account of yours. What would you do now as the decision-maker regarding the financing commitment?

First check, the rest will follow.
