I paid all of my utility bills.

One of them hired a landscape guy, well, the landscape guy never came so I was paying $140 per month for nothing for about 7 months.The other property manager didn't tell the tenants they were responsible to replace the ac filter, that bill was $1000 to replace the AC fan motor.I am really afraid of blowing off the money.

If that person were to get hurt somehow and then expect you to pay the medical bills or become disgruntled in some way it is just a phone call to DOR, OSHA or L&I. 

Quote from @Bill B.: I agree with that advice.

They billed us or overcharged us tohelp them have an income.

I like to stay in the working class areas as they make enough to pay the rent and bills, but don't have the financial discipline to save enough to purchase their own home. 

@David Woodside The 500-hour rule allows you to treat rental losses as active, enabling you to offset other income and reduce your tax bill significantly.

If in 20 years the house you purchased is worth 2-3X what you paid for it, and has been paying you cash flow per month that is equivalent (or better) than what the principal would generate for you, are you even going to care that you had a bigger tax bill one year 2 decades ago?

Include your business card with the bill at a restaurant.

And, when you see your next tax bill, your heart will stop.
