Tax Lien Sale Information

The Internet Tax Lien Sale will be held on November 7, 2013

The 2013 Tax Sale Interest Rate is 10%

Purchasing delinquent tax liens at sale is a popular form of investment.

Here are some facts to help you understand what a tax lien sale investment is, and what it is NOT:

  • When you purchase a tax lien sale certificate on property, you become a lien holder on the property. In essence, you loan funds to the owner to pay taxes.
  • You purchase the tax lien, NOT the property. In Douglas County, eventual transfer of deed has occurred in less than 1 percent of all purchases.
  • Investing in tax liens through purchase at tax lien sale is just that — an investment. The purchase can be thought of in terms of a potentially long range C.D.
  • The State Banking Commission determines the rate of return. The annual interest rate is set at nine points above the federal discount rate as of Sept. 1.

The Treasurer’s Office wishes to make it very clear that all sales are made with a “buyer beware” warning. While we make every effort to remove property with bankruptcies, FDIC or RTC connections, we cannot guarantee a property to be buildable or desirable.  In any legal proceeding involving a tax lien, Douglas county will not represent the investor.

    • The annual Tax Lien Sale will be conducted via an internet auction.
