My family and I vacationed in Bryson City for 10 years before setting up an STR there in 2022.

However, I expect them to vacate in less than 14 days because they claim the rental is killing them.

You have $606 after tax dollars to spend on the rest of life's expenses, including investing, buying flowers for your significant other, cell phone bill, water/electric/vehicle expense/food/childcare/hair cuts/vacation. 

My current property manager wants to charge one month's rent (plus 10% of all rents) to manage a property newly vacated.

(Max vacated rents - your monthly mortgage payment) = +/- net cashflow.

All,It is my understanding that I can not use a 10% second home loan and put it in an LLC to reap the tax benefits if I STR the property most of the time. I am wondering if I create an LLC to use as a managment compan...

I can that STR'S are definitely riskier than a LTR.Everyone needs a place to live, everyone doesn't need to go on vacation or travel.

Indeed, it's a numbers game, considering that you're not gonna live in the property.Of course, if you want to buy a vacation home or a short-term rental that you can use for yourself, it's another story as it wouldn't be a pure investment.

Keep the deposit. tell them directly they have to vacate before end of the month and maybe see if you can charge some early termination fee.
