How to choose home warranty?

[Yonna Wu]

As a new investor, I just bought a 2b rental condo. The HVAC is relatively old, while it is still working, it may stop functioning in some point. I am considering buying a home warranty to cover such case. Will it be a good choice? Any recommendations? I currently quote Liberty Home Guard and their price is around $408/ year if purchased 6 years at one time, or 550/year if purchased 3 years at a time. For American Home Shield, their price is almost $900/year.
