So far, we've looked into things like septic, property taxes, disaster insurance, plowing/cleaning, cell/internet availability, propane, mold, foundation, roof, airbnb stats, and water supply.

As a mom with teenage boys when I want to relax in a bath the last thing I want to do is clean their tub out lol.

Is that the kind of thing that can be cleaned up easily?

Are you doing the management and cleaning?

As in, nightly rent + cleaning fees + other fees.

My property manager has our cleaning fee set to $260 per stay. 

Everyone pays their portion of the rent on time and apartments are generally clean.  

However I’ve read threads where the landlord/owner has been cleaning the tenants’ mess in order to pass inspection 🤷🏻‍♀️

HOA fee - If HOA fees are not paid, the business will incur fines, so it is necessary to make a profit in the business.8) Marketing expense and advertising9) Cleaning and maintenance10)Commission (Expenses like commission, abstract fees, recording fees to obtain your mortgage are not deductible but rather capitalized )11) Insurance12)Legal and other professional fees(Tax preparation for business, not personal part)13)Management fee if applicable14) Points- you generally cannot deduct the full amount the first year but have to deduct them over the term of the loan.15) Repairs (Note always do repairs rather than improvements to rental because repairs are deductible right away and do not have to depreciate over a few years as done for improvements.

I agree about liability protection at some point, you might get an attorney to clean things up with your LLC, quitclaim deed the properties in, etc.
