We verified with the police that the unwanted guest was indeed still living in the rental with the main tenant, and that the unwanted guest had had a case of an overdose just a month ago in the rental.

OR are you just wondering whether you should rent it out or do short term rental or something like that?

I'm a little confused, are you looking for a 2-4 unit or a single family rental (SFR)?

@Christopher Lynch  NH has some amazing area's for Short Term Rentals.

For flips or rental properties? 

I currently have 20+ units that serve short-term, mid-term, and long-term rentals.

Purchase price: $674,000 Cash invested: $134,000 Long term rental purchased in area that is under development and predicted to rise in value over the next 5 years - 2br 2bth

My goal, is tax saving with the STR loophole, but also some rental income.

Part of it depends on your goals-do you want to buy more rentals in which case would selling or refinancing give you the money to do that and get a higher return? 

Please pardon my "verbose - ness" lol warmest regards shannon  Price it as a room rental or consider short term rental as guests don't need a full kitchen for that.
