I'm also asking for contractor, CPA, insurance, and legal references from the property managers and will speak with / cross-reference them before going forward with one. 

It's a factual and legal question.

Hey @Liz Zack I will start off by saying that I am not an attorney and this is not legal advice.I do not know all of the details here, but it sounds like you are going direct to seller on this deal.

I should have clarified some of the things you pointed out though as that is common practice buying a STR anywhere to verify what permits you need and how to operate legally in the city.

The only real way to create a "warning" is to pursue them legally to get an arrest or to get a money judgment - both of which will show on a background check.Although, all the tenant rights advocates are pushing to STOP landlords from being able to consider criminal history in tenant screening:(

My question is, can I legally rent this space?

(Also, caveat to make sure this is all legal in your state as each is different)One - they are going to move out and leave a ton of stuff behind.

It is working as intended and is not a way around things.Loophole-A way of avoiding or escaping a cost or legal burden that would otherwise apply by means of an omission or ambiguity in the wording of acontract or law.

It's also good for insurance and legal reasons, because you will need to indicate every adult and all persons, as well as details (like children, pets, etc.), on the lease.  

The question I have, is there a legal way to assume the mortgage since he has such a great rate?
