Do you cover broken blinds as part of unit maintenance.
Ex. Tenant calls saying a 4year old blind is broke and wants fixed or replaced.
I would replace it. It should have been an inexpensive set to begin with unless you're talking a high-end house, in which case you'd replace it because it's a high-end house. The blinds I buy cost less than $10 per, and if they last 4 years I'd be happily surprised.
