Any Efficient Process to Organize your Rental Properties?

[Sam Mathew]

I am request assistance from a wise rental property sage on how best to organize rental property paperwork.  I have out-of-state properties with property management companies to manage them, but still I have closing docs, titles, insurance, mortgages, HOAs, expenses, etc....some permanent records, some ongoing monthly accounts with updates.  Some reason I have no effective folder system, excel spreadsheet, or online softward to help me keep track.  Yes, slightly embarrassed to even type this out but if you might be able to help, please let me know.  Thank you Bigger Pockets' members.
