Your REALTOR should be able to provide you with your tax rate. Be careful not to get caught up in semantics. Though it is true that Eastvale is not set up as a Mello Roos District, much of the area is subject to "Special Assessments". These assessments are substantial in some neighborhoods and and nominal in others. But as I said, your REALTOR has access to Real List tax Data and will be able to provide you with the information that you are requesting.
And, even though Mello Roos fees are technically not the same, they have one important thing in common, and that is that they can add substancially to your home operating expenses.
Definitely check with the city and county to be sure, but there are pockets of areas all throughout Corona, especially in the 92882 area where there are extra Mello Roos taxes and homeowners associations.
I lived in the southern section of the 92882 part of Corona and it was a great neighborhood. I dont think you will go wrong with any areas in Corona as long as you look ahead of time and do your homework along with your realtor.
If you have any questions or if I can be of any further assistance, please feel free to contact me.

Remember to also check to see if the neighborhood you're interested in has an HOA fee.
