Home warranty for duplex

[Michelle Crochet]

I am wondering if it's really worth it to keep a home warranty on our duplex in phoenix?  Often they won't cover things that seem like they should be covered, and it's $900 per year, so not cheap.  Also, it seems prudent in some ways to have it.

Appreciate feedback from those with many rentals who may have had success or failure using a home warranty.
