I have applied for my citizenship and am researching the real estate industry here.

Consider cleaning, lawn care, snow removal and supplies as well as utilities  in your calculations.  

The main thing being: giving up a property that appears to have appreciated pretty well is just a touch pill to swallow and I've regretted a few moves I've made when put in a similar situation to yours, and I had less equity in mine.It sounds like you're moving to Raleigh in the near future and want to buy a multifamily to househack.

The property jumped another 100k less than a year after the sell as well as rents went up to support what would have been the new monthly debt if I refinanced and held. 

This Wikipedia page gives different wall types and how well they block sound.  

I intend to add a closet to the den and make it a 3 bedroom adding value as well as remodel the entire unit.

I also agree that Akron is a viable area as well, but Im still finding the best deals in and around Cleveland.

If I am hell bent on renting by the room (I don't think that is a good LONG-TERM strategy, will elaborate later), I can do that on both sides of my duplex as well.  

Ask them to update your photos and put your best foot forward.If the market is doing well and your PM is marketing poorly, then you have a case for complaint and/or moving to a new manager.

With your background in real estate (STRs and assisted living), commercial MAY make more sense and then if there are any residential deals you can take them as well.
