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.
I used to have more access but our illustrious legislators have restricted ANY services that the title companies provide to realtors without charging us. Somewhere they believed that title companies providing those services created a loyalty with between title companies and realtors that hurt the general public. ..... that garbage has hurt us all. (sorry I digress)
Hope that helps.
