Properties are sold "AS IS"
The sale of these properties should not, in any way, be equated to real estate sales by licensed salespeople, brokers or realtors. The County of San Mateo makes no guarantee, expressed or implied, relative to the title, location or condition of the properties for sale. Property taxes currently due will be paid from the proceeds of the sale.

Important Disclaimer
The County of San Mateo is not liable for the failure of any device that is not owned, operated, and managed by the state or county, that prevents a person from participating in any sale. A “device” includes, but is not limited to, computer hardware, a computer network, a computer software application, or a computer web site. The County of San Mateo assumes no liability for any other possible liens, encumbrances or easements, recorded or not recorded.

Please Note
Prospective purchasers are advised that some bonds and/or assessments levied by agencies or offices, other than the Treasurer-Tax Collector’s Department, may still be outstanding after the tax sale and that the Internal Revenue Service has the option of redeeming, within 120 days after the sale, any property on which there is an I.R.S. lien recorded.
