Unless things have changed in the last year and I don't think they have, the tax base for most of the Retreat is at 1.1%. the last client I had in there had a mello roos of $3900 a year. Yes $3900! They are not all the same though. You can put in an address on this link and should be able to check taxes. https://taxpayments.co.riverside.ca.us/Search.aspx
It sounds like a lot of tax and in comparison to a lot of other places in Corona I guess it is much higher; however; consider the amminities and security and overall feeling you have of living in that type of community. There really in my opinion is no comparison to anything else out there. I believe it is a matter of "You Get What You Pay For" Absolutely beautiful community.
Payment on a $500K home with 20% down is about $2,604.00 PITI Plus the Mello Roos of about $325
**Total Approximately $2,929
**this is assuming your credit score qualifies you at 4.5% loan rate. and Mello Roos is at $3900
