Dear Ms. Santos: The answer to your question is five times since 2002. Earler then that data is not available to me through my sources. It appears that title transfers have been made by the owner into different entities. The last transfer was a Trustee Sale to the lender (foreclosure).
If you need information from 1998 through June 2002, I would suggest going to the Sacramento County Recorder's office. You can access this information at no cost to you and it is public record. They are located at
600 8th Street
Sacramento, CA 95814
If you have a relationship with a local title insurance company, they may be able to do the legwork for you, but it could cost you a fee.
I hope this helps.
