They would throw trash all over the property and cut garbage bags.

Whereas when I do this in a market where I'm invested and some others I'm interested in, there are maybe a few dozen listings at best, and 80-90% of what's not booked is either garbage or too expensive. 

If you're buying small multi family (an option i recommend), look for markets with cheap water/sewer/garbage bills in the event they're owner paid.

Garbage?

I would have taken photos and given  her a bill that day for repair.The plumbing clogs, give her written notice that this sink is not a garbage disposal, and that grease and rice, was reason the drain clogged per your plumber and future plumbing issues of this type will be charged back to her.Same with toilet, provide her a plunger and advise excess of toilet paper is her responsibility for and plumbing calls.

I would look at 2017-2019 and use those years to compare and throw 2020-2022 in the garbage as those years are artificially inflated

We hired guys to take out the garbage.

As a result, the city as a whole, was cleaned up but at the expense Kensington, which saw an influx of drugs, garbage, and homeless encampments.  

Its the stove the city cracks down on, as you can work around this by installing a wet bar which can include a sink and fridge,does not include a stove, built-in microwave, dishwasher, a garbage disposal, or a gas line.With the second kitchen your house would act more like a duplex with two units rather than a house with roommates, in practice the pwnership experience is pretty different when you have a separate entrance and separate dwelling units. 

Same with loud music at parties, parking on the street and a really big one is the garbage recycling.
