Riding a bus is easier than being packed into an over crowded subway like a sardine. 

Not crammed in like sardines with urban core but not out in the middle of nowhere with no civilization to be found like rural.

You're got five people living like sardines in a small house in a high humidity part of the country.Gail

The smallest building is 340 with its kitchen, bathroom, living area, and entrance but it's like sardines in a can.

When a landlord has great occupancy and slightly above market rents it's because they screen properly.They also have good tenants lined up at the door to rent even though rent is slightly higher.The reason is the landlord builds a rep for taking care of their buildings and when a problem arises the landlord fixes it quick.Just like bad tenants you get slumlord landlords out there who don't want to fix anything and pack people in like sardines which is against city code health and fire ordinances.So it all comes down to if you run your properties right and have bought them right to begin with then good tenants will find you.If you have a run down piece of crap you will invite gangs,drugs,no pays,high turnover and everything else under the sun.I believe at their core most tenants want a nice,clean place to live for an affordable rate.

There simply are so many places I'd rather be, with people not stacked one on top of another like sardines :) 

They are packing them in like sardines. 

* "Is it even worth it suffer in a room packed like a sardine in order to invest?"

. , it's not a standard subdivision home, ete. where it's like sardines packed in.

I have seen multiple houses where they create unsanitary living conditions, pack people in the home like sardines and attract crime.
