The docs you see complaining are the ones working like dogs cause they have no other hobbies or interests outside of medicine and act like they are forced to work day in/day out.If I can continue to practice medicine for free someday, because my investments are able to float my lifestyle, I would.

For me, this would mean asking about pets (we don't allow cats of any kind, or aggressive breed dogs, or dogs over a certain weight in our condo units that have HOAs that prevent it). 

Then they bring in a bunch of people, promise them they can make tons of money, work them like dogs, and then kick them to the curb if they don't produce.  

I didn’t make a fuss of things because 1) the utilities that I covered remained consistent and didn’t cost me more, and 2) neighbors didn’t complain about the dog. 

Use a good dog or live an let live.

I've done a credit check and application for the prospective roommate, and she has pretty bad credit with multiple collection accounts plus a dog (she says her ex spouse ran up the bills) -- which would make 3 dogs for the apartment (current tenant has two very small dogs).I'm struggling with what to do.

Current tenants are willing to sign early termination because they want a dog. 

In exchange for free rent/utilities/internet/streaming services, they would buy food, cook and help me take care of my dogs. 

I have a tenant moving out, they have been with me for 5 years the carpet was not new when they moved in but they have a dog paid $250 pet deposit.

Secondly, I don't think a 1031 into anything is going to be your best move unless your properties are dogs.
