Insurance Companies

I’m still under my parents auto policy for car insurance, but I live on my own now in the same state. The auto insurance company we use sells renters insurance too. Can I get a renters policy through them to save on my rate even though I’m on my parents auto policy? I don’t want to get in trouble on my auto policy since I’m not living with my parents anymore.
To add information, I’m a 20 year old male and own a sports car. Putting my car on my parents insurance qualified us for the multi-car discount. I need renters insurance to cover things like my computers, hdtv, video game consoles, and other equipment associated with them as I could not easily afford to replace them.
Also, my current auto policy under my parents insurance is $63 a month for full coverage.

Any renters policy will be separate from the auto policy. You won’t be able to save. Renters insurance is not that expensive – just get it on your own.
