My daughter lives in Salt Lake City. Her rent is $1,500; if she's one day late, the late charge is $250. And, as an earlier poster mentioned, an additional fee for each additional day. She missed some work, knew they were going to be a couple days late, and called her landlord ahead of time. He laughed and said that's just in the lease for the "hard cases" -- grifters, liars, chronic bad payers. He wouldn't charge her a late fee because she's a good renter with no record of late payment.
Never hurts to ask!
My rent is $250 a month for 2 bedroom, 2 bath (with 2 car garage) house. I've been in this house for 12 years. I've probably been late 12 times. I have OFFERED a late fee every time, and my landlord just smiles and says it's not necessary. In ten years, he's never raised rent, either.
I LOVE Nebraska!
