Maybe operate it as a mid-term/short-term rental?

If your rent is significantly below market for the area, you are essentially operating a charity.  

I am looking for some current operators in Sandbridge to chime in on this one.

I have also managed the day-to-day operations which involved me ensuring all amenities were stocked, coordination with the cleaning staff, and handling communication with challenging guests.My Remote work skills have proven me to be a great asset for my property owner who was not much involved in running their airbnb rental but was well-informed by me. 

If you really want to go down that path, I suggest that you apply to work for a syndicator or RE Private Equity shop as an analyst or operator for a year or two, and browse through 100+ deals over that time period, underwriting each one, and trying to figure out, over that time, which ones you were "right" about, and which ones you were "wrong" about, as best you can.

400+ flips, nearly a billion in transactions and over 4K units under management, experience/operations in 27 states, 5 countries, 3 continents.....

With an Operating Agreement, separate bank account, etc.? 

Angela Harding TPM Realty  Sorry my english not good I from ukraine, what it means "rent a broker's" Rent a brokers mate is when the officer of your company is a licensed broker so you can legally operate.$1,000 per violation and per day if you manage properties without a broker.I know if folks managing thousands illegally in Toledo.If only I was a whistle blower hehe10% fee from the total fine isn't a bad pay day, right...?

I personally just attend 1 to 3 auctions in my home state of SC.Personally, I attend as many auctions as I can :)I actually have my list of favorite states and counties, but with good organization and a detailed plan there are no limits if you operate online.

Both of those neighborhood (all of City of Boston in fact) would need for you to be an owner occupied operator, are you planning on moving to NE?
