Let me just add some clarification for everyone's consideration: These contractors have not been messy or rude in the past and are on time the majority of time that I've worked with them. The tenant requested the repairs due to smoke stains on the ceiling. I figured that I'd add an exhaust fan while I'm replacing the ceiling for proper ventilation (also the tenant signed the lease acknowledging that smoking is not allowed). This is an inherited tenant (my first one) on a property I bought about 4 months ago. She routinely fails to pay her rent on time, and I just received a complaint from the downstairs neighbor because she leaves her trash outside for the rodents to feast on. She's terrible at communication (barely responds to my messages).
Also, while I'm in this business to make money I'm also in it to provide affordable and safe housing for my tenants as I grew up in the safe neighborhood and none of the landlords that I know out there are ethical.
