So, rent a machine that removes odors - forget what it's called - but you can rent machines that do this - ozone machines?  

When I purchased the home it came with an older functioning washer machine that has been at the property.

Don’t forget the google machine for screening, you can even find ninjas on there if you look hard enough.

Put in coin operated machines.

Get your initial investments to an infinite return state, which will start to generate momentum for you to expand your wealth machine. 

It went from things like wanting me to let them have a washing machine in the unit even though the owner said no to them and after I explained it's because the pipes can't handle it and sorry, I'm not losing my job over it for you (in a very nice way) -- furious reaction, no more friendship.... to wanting me to tell their neighbor to stop having such loud sex (not kidding) and when I said I don't tell other tenants how to have sex (again in a very nice way, while giggling no doubt), I lost that friendship. 

I make home decor with my Cricut machine!

For instance, "I'm sorry, but our policy is that we don't allow portable washing machines in any of our units."

Sadly, you might need to explain to them how to use a washing machine and how much stuff you can put in it.
