Routt County, CO
Online lien sale via Zeus Auction, registration closes Oct 29
Routt County's annual online tax lien sale, covering unpaid 2025 property taxes on real property and severed mineral interests, runs October 30 through Zeus Auction. Registration opens October 2 and closes at 2:00 p.m. MST the day before the sale — bidders need a completed W-9 and bank account on file before bidding is enabled, since all payment runs through ACH only.
Colorado's rate is set annually at 9 points above the federal discount rate (13% for certificates sold from October 1, 2026) and doesn't get bid down — instead, competition happens through a cash premium bid on top of the lien, which isn't returned with interest if the lien redeems, only the face amount is. Routt's own sale page also flags a recent Colorado law requiring a secondary auction after a certificate holder applies for a treasurer's deed, specifically to make sure the original owner gets fair value if the property is actually deeded.
Colorado rules at a glance
Colorado's rate is nine points above the federal discount rate, set each September 1 by the State Bank Commissioner (C.R.S. 39-12-103): 13% for liens sold from October 1, 2026. Bidders compete on a premium that goes to the county and earns no interest (C.R.S. 39-11-115). From August 1 of the third calendar year after the sale the holder can apply for a treasurer's deed, which now means a public auction (C.R.S. art. 11.5); the owner can redeem until seven days before it.

Property & tax profile
The median homeowner in Routt County pays $2,736 a year in property tax — above the Colorado median of $2,602 (U.S.: $3,119). That is roughly what a typical home here owes after one missed year — about the face value of a one-year certificate, before interest, fees and any premium. Homes with a mortgage pay a median of $2,706; homes owned outright, $2,829.
On a home with a mortgage, the lender has its own reason to pay a delinquent tax bill: the tax lien outranks the mortgage, and a tax deed can wipe out the loan. On a home owned outright, nobody but the owner — or the heirs — has that reason. In Routt County, 33.9% of owner-occupied homes are owned outright (Colorado: 30.6%, U.S.: 39.4%). That is more than the state as a whole, so a larger share of the delinquent bills here have no lender behind them.
34.3% of all housing units in Routt County are vacant. 25.3% of all units are seasonal or vacation homes, empty by design rather than abandoned. The figure that matters for a lien buyer is the Census “other vacant” category — not for rent, not for sale, not a holiday home, but a catch-all that includes foreclosures, homes held up by legal proceedings or family reasons, homes needing repairs, and abandoned ones. Here it is 2.9% of all units (Colorado: 1.7%, U.S.: 3.6%). That is above the state rate, so expect more empty properties on the delinquent list: the ones least likely to redeem, and the most likely to need work if the deed ends up yours. Drive by before you bid.
Half of the homes in Routt County were built in or before 1993 (Colorado: in or before 1988). The typical tax bill is 2.6% of the median household income of $106,489 (Colorado: 2.7%).
