I even had this problem in my personal home and a steam mop handled the issue,

It involves ground work, gravel, possibly concrete pads or blocks.

Does it need to go in a BUSINESS savings account or can it go into a PERSONAL savings account? 

Build relationships and don't treat every person as a transaction, and these types of things won't happen to you.We lend to plenty of investors who use the same wholesalers time and time again and don't try to do any of these things because the numbers work for everyone.Build a quality book of business and none of these things will be issues.

I really like the equation, though, because it does encourage/provide the idea that house hacking can truly increase your personal net worth and be a better option than for example  (having a relatively higher income in town A but you rent versus lower income in town B but you house hack -- the NWROI may tell you house hack in town B!

Rely upon your own attorney's advice, and not personal opinions from others.  

House hacking will also give you some personal "property management" experience.

All my personals are never less then 15% most avg 20% NET Good luck
