7 year carpet and a curious quirk
Just talked with our local Multi-Family Housing council hotline in Portland, Oregon and he said the courts here support prorating carpet over 7 years.
But, he says if there is pet damage you are entitled to have the carpet replaced 100%, no prorating. He says the court supports that claim. Interesting.
If you have a council like this in your city I'd suggest joining. I have a vacancy coming up and he is sending me updates.
If 7 yrs works here don't see why you couldn't try it.
