Your best resource would be your realtor, ask for a tax disclosure report that they can obtain from the assessor's records. Each property is unique, true we are all graced with the Jarvis-Gann Prop. 13 that dictates we have a maximum of 1% of the assessed value. It is the local governments that add on Mello Roos, or we vote for additional bonds and issues that add to the bottom line for each community. Ergo, each property is unique unto itself, some can carry their tax basis from one property to another over the age of 55 in the same county...so many variables can affect. Again, check with your favorite realtor, they will provide priceless resources to assist you in making your own final decisions.
