Simple he said/she said situation and Suzie will have to deal with her temporary "guest".If there is a official lease in the possession of the new tenant then it is again Suzie's problem not yours.

I'm hoping to make this trailer a temporary home for me and my kids.Again, I just want to know what I have to do, to get them out once I have the deed.

and I'm hopeful we can in 2022 (after 1.5 yr. lease is up).To the millennial demand I agree on that point too, I think a lot of people are worried about there being some sort of housing crash but right now I see 1) millennials are buying their first homes driving up demand and this will continue for years, 2) people are moving out of urban areas (I see this as temporary for the majority of people but there will definitely be a large portion that never move back), 3) interest rates are at historic lows, and 4) inflation is around the corner (maybe not this year, but 2022-2023 I could see it as the government needs to inflate away its debt).

Are you seeing a --temporary-- dip in prices starting now? 

I'm hoping this current rent collection headache will only be temporary.

Quote from @Frank Jennings: You can give your Tenants written, detailed, temporary authorization to contact the contractors in your absence if there is an emergency maintenance issue.

One thing I have added is that no portable/temporary washing machines or dishwashers are allowed in units.

Is it a temporary problem like a car repair, failure to prioritize rent, or a money management issue?

.:) Some day I'll tell you my squatter story, but for now...think I'll keep that one behind " lock & key " Thanks again Aaron for your views on the lockbox quandary & seriously, now in my 50's, the thought of seeing myself crawling through a dirty window possibly falling onto a nasty,stinky ,bacteria breeding carpet remnant scares me as much as the thought of who might be taking up temporary residence on that nasty, stinky....

Ive hired a temporary Property manager for the 8 or so months that I am gone every year, and I take back over during the summer months.
