Important Information
Research Before You Invest!
The sale of these properties should not, in any way, be equated to real estate sales by licensed salesmen, brokers and realtors. The Auditor-Controller/Treasurer-Tax Collector cannot guarantee the condition of the property nor assume any responsibility for conformance to codes, permits or zoning ordinances.
You should inspect the property before investing. The burden is on the purchaser to thoroughly research before the sale, any matters relevant to his or her decision to purchase, rather than on the county, whose sole interest is the recovery of back taxes. Any research on these properties will need to be facilitated by the purchaser. The county offices provide information during regular business hours.
It is recommended that bidders consult with the Zoning Department of any city within which a particular parcel lies, or the Zoning Section of the County Planning Department for an unincorporated area parcel.
Should the successful purchaser desire a survey of the property, this must be done at the purchaser's own initiative and expense. No warranty is made by the county, either expressed or implied, relative to usability, the ground location, or property lines of the properties. The exact location, desirability and usefulness of the properties must be determined by the prospective purchaser prior to the sale.
Tax-defaulted property will be sold on an AS-IS basis. This is a “Buyer Beware” situation and ALL SALES ARE FINAL.
