Tax Lien Sale

General Information

An annual Tax Lien Sale will be held the on Thursday, November 6, 2025 to collect the unpaid property taxes. These taxes are purchased by investors and become a lien against the property. The investor earns interest on the tax lien against these properties. The interest amount (paid on the tax lien, but not on the premium) is determined September 1st every year and is nine percent above the federal discount rate (rounded up). The rate for 2025 is 15%. The amount of the individual tax lien purchased includes the amount of taxes, delinquent interest, advertising, internet auction, and certificate fees. Generally a successful bidder pays a premium price above the tax liens that are sold in order to purchase a tax lien certificate.
Three weeks prior to the tax sale, a list of the properties that have the potential to go to sale will be available to view at RealAuction. This list is updated daily until the tax sale date.
It should be noted that the property owner may redeem the property from the tax lien certificate holder at any time subsequent to the tax lien sale and up to the issuance of a Treasurer’s Deed.
Per Colorado State Statute C.R.S. 39-11-151 no tax lien shall be sold to county officials or employees or to a member of the immediate family of such individuals.

Element of Risk

Please conduct your own investigation in order to reduce the risk.

Lien Redemption

An email will be sent to the investor with a Certificate of Redemption for each redeemed property. Redemption funds are sent via ACH within three weeks after the redemption.
