Larimer County at a Glance
Larimer County centers on Fort Collins, home to Colorado State University, alongside Loveland and the mountain gateway communities of Estes Park. The local economy blends higher education, a nationally recognized craft brewing scene (New Belgium, Odell, Fort Collins Brewery), technology employers, and agriculture along the Front Range's northern edge. This diversification supports steadier demand than resort-dependent mountain counties, while competition remains meaningfully lower than Denver Metro.
Larimer's moderate competition rating translates directly into better achievable rates. While Denver's conventional residential parcels get bid down to 3-6% by institutional buyers, comparable Larimer County parcels typically settle in the 7-14% range — a substantial difference over a 3-year hold with subsequent tax payments factored in.
CSU creates a distinct rental submarket in Fort Collins. Properties near campus turn over on academic-year cycles and can have different delinquency drivers than owner-occupied housing elsewhere in the county — often tied to absentee landlord issues rather than owner hardship. Research ownership patterns separately for this submarket.
Loveland and the eastern county see somewhat less competition than Fort Collins proper, while Estes Park and the mountain gateway communities carry high property values with correspondingly motivated redemption — a useful combination for interest-focused strategies.
Larimer County's tax lien sale is held annually in October, conducted by the Larimer County Treasurer. The delinquent property list is published several weeks before the sale — contact the Treasurer's office directly to confirm the current year's registration deadline and deposit requirement, as these details can change year to year.
Bidding starts at the current year's statutory maximum rate and moves downward as investors compete. With moderate rather than high competition, individual investors have more realistic room to hold a defensible floor rate on desirable parcels than in Denver or Arapahoe. Arrive with a researched parcel list and your maximum acceptable rate set in advance for each.
The variable statewide rate applies here too — always verify the current year's figure at dola.colorado.gov/dpt before finalizing your bid strategy, since it changes annually with the federal discount rate.
How Larimer County's Tax Lien Sale Works
Bid-Down Auction
Larimer County holds its annual tax lien sale in October, run by the Larimer County Treasurer. Register in advance with a deposit. The delinquent list is published ahead of the sale. Bidding starts at the current annual maximum rate (verify at dola.colorado.gov/dpt each year). Bring a researched parcel list rather than bidding on the fly.
Variable Rate — Bid Down From Max
The current rate is the federal discount rate + 9% — approximately 15% in recent years but changes annually. Larimer's moderate competition typically allows better achieved rates than Denver Metro. Payment is due promptly after winning — confirm the deadline with the Treasurer's office. Interest accrues from the sale date.
Redeem or Apply for Deed After 3 Years
Owners have 3 years to redeem by paying the certificate amount plus accrued interest. You may pay subsequent delinquent taxes and earn the same rate. After 3 years unredeemed, apply to the Larimer County Treasurer for a treasurer's deed (C.R.S. § 39-11-128). No court action required in most cases.
