No matter how nice PMs are, you have to inspect what you expect or they will eat your cash flow alive!

I own 2 STRs in Gatlinburg and definitely see massive returns but I don’t want to put all my eggs into one market so I’m looking to branch out.

The general rule of thumb is the management fees for a property manager are going to eat up your profits and you'll end with the same profits you would as a LTR. 

(Am open to class B neighborhood, but high prices & prop tax will certainly eat away at         cashflow)2:  Any insight on what cashflow investment markets in Raleigh, Nashville, & Austin are like? 

Biggest issue is the tenant population after you get a good exterminator.If they like to leave half-full boxes of cereal open on the counters, you can gas the place and they'll come right back since you can get rid of living ones, but not the eggs so much.Does the exterminator see anything else unusual about the place to make it a breeding ground?

If you don't have any sort of nest egg, you may want to question this purchase or identify alternative forms of financing so you have a buffer in case things don't go as planned from a cash flow perpsective. 

Now the rates are low enough that it is probably worth it to eat the prepayment penalty and refinance. 

Pro and cons for keep the property:pro: 1. we are not losing much money on the rental property2. although appreciation increase ~5% for the past few years, potential is good3. familiar with local, we know real estate/loan agents, handyman, friends could help us handle any cases.cons:1. we could get tax deduction to sell it next year since it qualified for our primary house.2. remote management is frustrated. but hire manager to manage it almost eat all our cashflow2. the house is too large, not a good invest property for 5% increase per year, cash out and invest in something else MAYBE betterIt really cause me headache whether or not we should sell the property, it is on the line of making/losing money.

Taxes are eating me up...

However, you as the owner have an obligation to make sure heat/hot water is working but all the while they can break things and making formal complaints about the condition of the home that will be documented against you.Unfortunately you will likely have to eat some sh*t pie and let them leave.
