Notes

Colorado tax-lien (certificate) county, not a direct deed auction. Weld County Treasurer sells Tax Lien Sale Certificates of Purchase online at weld.coloradotaxsale.com. Next tax lien sale November 5, 2026. Certificates earn statutory interest; after ≥3 years a lawful holder may apply for public auction of Certificate of Option for Treasurer’s Deed (post-HB 24-1056 process). Separate deed auctions use RealAuction wire deposits. Certificates issued after Jan 1, 2026 expire after 7 years per county materials.

Deposit rules

Register online with W-9, ACH authorization, and buyer-beware acceptance. Deposit minimum 10% of planned lien spend via ACH before bidding; final ACH settlement for won liens. Deed-option auctions: wire ≥10% of anticipated high bid to RealAuction by 4 p.m. MT day before auction.

Title risk

Liens that survive the sale

Certificate is a lien only — not ownership. Other liens remain until Treasurer’s Deed process completes. Federal liens and certain interests can survive. Research Recorder and Assessor records before bidding.

Quiet title

Deed path requires statutory public auction of option and post-sale steps; title insurers typically require completed Treasurer’s Deed process (and often quiet title review) before insuring.

Colorado assesses residential property at two rates since SB24-233. For school district purposes the 2026 residential rate is 7.05% of actual value; for local government purposes 6.95% is applied to actual value less the lesser of 10% of actual value or $70,000 as adjusted for inflation, an effective rate near 6.26% below $700,000. Commercial and agricultural property is 25% for 2026, down from 27% in 2025. This entry uses the school rate, the higher of the two residential figures.
