Good Morning Thankful,
I too, am a business owner. When I submitted my paperwork to the NACA, they requested the last 6 months of bank statements for my personal and business accounts. Please make sure when you send your bank statements, you send each page, front and back in chronological order. They also asked for an itemized list of my monthly business expenses.
They did request a statement for property taxes and my Homeowner's Declaration page from my insurance policy, even though they were escrowed into my mortgage payments.
Hope this helps.
