Fun fact on homelessness, they actually invented a magical vaccination for that "disease" many MANY years back that has all but 100% effective rate.

Don't remove trees unless they're trash trees like gum balls or diseased. 

I had an autoimmune disease that went away just from fasting. but of course i lost weight too lol 

you are kind of dealing with three diffrent issues here, the thing about not being a legal three unit, super easy don't buy something that's not legal, and your agent really shouldn't be encouring you to break the law, the issues with properties being beat up, the vast majority of multi unit's that sell have some wear & tear that's often the reason for selling, being a tired landlord, if you want turn key, you are proably looking more single family homes or paying big dollars for a turn key multi if it even exists in your market, 3rd we can debate the pro's or con's of this this market but youve hired and agent and 99% of agents are going to tell you its a great time to buy, i'm usually more measured but that's because I have a deep psychological problem in which I care more about being intellectually honest than making money, most agent's however are not afflicted with this disease so your gonna have to make this decision for yourself before you hire any agent.

With larger multi-units, there's a common issue I call the "chronic disease of a fourplex": - One tenant might leave within a couple of months, with or without a valid lease

They are not checked for disease at the boarder, they are given airplane flights to your city with no TSA check, (they have no Identification) and are told to report to immigration processing two years from now which less than 1% follow that requirement.So, bottom line, I've bought houses from illegals, I've sold houses to illegals and I've hired illegals.

it's tax-free for something that you can't enjoy until someone is older enough to have a stroke,cancer and other diseases.

Maintain your hot tub properly so no one gets "hot tub rash" or Legionnaire's disease. 

In fact, it takes away value, like a disease. 

Last thing I'd want is a source of disease and other nastiness rotting away inside one of the walls.
