It sucks but that's what is required when you own property.

The only reason I got an LLC was to buy a commercial property because it was a requirement of the lender.

While they generated some cash flow, I found the effort required to manage them wasn’t worth the return.

My contract with my property managers requires my approval for any expense over $500.

If they sell them on amazon, they likely don't require any special handling.

Just my personal opinion - get a mentor or a person who already has good experience running STR business, preferably in your area (but not 100% required). 

The seller requires a cash purchase & I’m exploring creative ways to structure the deal.

I have two options 6.625% 30 year or 6.15% 15 yearI want to invest aggressively in the near future on more propertiesThe loan is only $110k and the monthly payment for 15 year is $563 and $750I will earn 2-3k a month in gross rental revenueThe property is in a declining population areaRecently rennovated, and all major things were relatively recently improved such as plumbing, the roof, a/c, electric, etc.Will require a lot of management as it is rent by the room so I may switch to a normal rental after 10 yearsI'm trying to find what will mathematically net me the most money in the long run.

If you ask the manager to justify a fee and he starts hemming and hawing, move on or require them to remove the fee.

These types of properties require experienced management to navigate the challenges effectively.
