What these numbers mean for buyers and investors

Costilla County is currently showing a very tight tax-delinquent market. The County Treasurer has identified 1 property in active tax delinquency status as of late June 2026. This low count reflects either strong property tax compliance across the county or a small residential and commercial footprint, or both. For comparison, the same snapshot shows 2 properties entering the property auction pipeline and 1 property in preprobate proceedings, suggesting a modest but steady flow of distressed or transitional real estate.

The convergence of these three signals tells an important story. A single tax-delinquent property against a backdrop of 2 auctions and 1 preprobate case indicates that Costilla County's property distress is not concentrated in unpaid taxes alone. Buyers and investors should understand that opportunities here are sparse and competitive advantage comes from speed, local relationships, and willingness to pursue the full range of county-court dockets, not just the tax-delinquent roster.

For small investors or first-time buyers, the low volume is a double-edged sword. The lack of many tax-delinquent properties means less choice and potentially higher valuations when one does appear on the County Treasurer's list. However, the same thinness also means less competition at auction, and any property that does go to tax sale may represent genuine opportunity if due diligence is thorough. This is a county where patience, persistence, and familiarity with the County Treasurer's office pay off.

How to get the official Costilla County tax-delinquent list

The authoritative source for Costilla County tax-delinquent properties is the County Treasurer. This office maintains and publishes the official list of properties in tax delinquency and schedules all tax sales.

To access the list, contact the County Treasurer directly and request the current tax-delinquent property roster. Ask specifically for the date of the list to ensure you have the most recent version. The Treasurer will inform you of upcoming sale dates, property locations, tax amounts owed, and any other conditions relevant to each listing. Many Colorado county treasurers now publish lists online or provide them in digital format upon request, so inquire about the most current publication method when you call.

Once you have the list, verify every address, legal description, and outstanding tax balance with the County Treasurer before proceeding. Ask whether the property is owner-occupied, what liens or judgments attach to the title, and whether the property is in or out of statutory redemption (meaning whether a prior owner or lien holder can still reclaim it after a tax sale). The County Treasurer can also direct you to the County Assessor, who holds property value and parcel information, and to the County Clerk and Recorder, who maintains the official deed and lien records.

Request written confirmation of the redemption period, any upcoming sale dates, and the opening bid amount. Having these details in writing prevents misunderstandings and allows you to plan your bidding strategy in advance. The County Treasurer is your starting point and your ongoing point of reference throughout the process.

How Colorado's tax sale and redemption process works

Colorado law provides a formal, multi-step process for collecting delinquent property taxes. Understanding this process is essential before bidding at a Costilla County tax sale.

A property enters tax delinquency when the owner fails to pay property taxes by the statutory deadline. The County Treasurer then issues notice to the owner and any known lien holders. If the taxes remain unpaid, the property is scheduled for sale by the County Treasurer.

At the tax sale, bidders compete by offering prices above the opening bid, which is typically the amount of back taxes, interest, and administrative costs owed. The highest bidder wins the property and receives a tax certificate or deed, depending on the stage of the process and Colorado's redemption law.

Colorado law grants the original owner and other parties with liens or interest in the property a statutory right to redeem, or reclaim, the property after the tax sale. The redemption period and the mechanism by which redemption works depend on the type of sale and the property's history. During redemption, the original owner may pay off the winning bid amount plus interest and costs to recover the property.

If the redemption period expires without redemption, the County Treasurer issues a deed to the tax sale purchaser, and that purchaser gains clear title (subject to existing liens and encumbrances that survived the tax sale, and subject to any rights of occupancy or possession owed to tenants or resident owners).

For exact redemption periods, opening bid amounts, and sale dates specific to Costilla County properties, you must confirm these details with the County Treasurer. Colorado law sets the statutory framework, but application to your particular property requires county-level verification.

Due diligence and risks

Buying at a Colorado tax sale carries significant risks. A thorough due-diligence process is not optional; it is the only defense against purchasing a property with hidden liabilities or unfinished business.

Before you bid, search the county records for all liens, judgments, HOA assessments, and special assessments against the property. The County Clerk and Recorder's office holds these records and can provide certified title searches. A property may have junior tax liens, mortgage liens, or judgment liens that do not disappear in a tax sale and will attach to your ownership after the sale.

Visit the property in person. Determine whether it is occupied. If tenants are present, their lease or occupancy rights may survive the tax sale, and you may inherit their tenancy. If the property shows signs of code violations, environmental hazards, or severe structural damage, calculate whether the cost of remediation justifies the purchase price.

Research the property's tax history with the County Assessor. A pattern of delinquency suggests cash-flow problems or abandonment. Check local criminal and civil court records to see whether the property has been the subject of code enforcement, nuisance abatement, or other government action.

Confirm the redemption period and the exact date on which redemption expires. If the original owner redeems after you have taken possession, you must vacate and return the property. Some properties in redemption are occupied by the original owner or a tenant, creating uncertainty about when you will actually gain possession.

Verify utility connections and easements. Ask the County Treasurer whether the property has access to county water and sewer or relies on a well and septic system. Confirm that no utility easements or rights-of-way will interfere with your use or resale.

Frequently Asked Questions

How do I get Costilla County's tax-delinquent property list?

Contact the County Treasurer directly. Request the current tax-delinquent property list and ask how the office publishes and updates it. The Treasurer can also provide information about upcoming sale dates, property addresses, and the opening bid amounts. The Treasurer is the official source and the only office that can give you verified, authoritative information about delinquent properties in the county.

When is the next property auction scheduled in Costilla County?

The County Treasurer schedules tax sales and will provide you with the date when you request the delinquent property list. Currently, 2 properties are in the auction pipeline as of June 2026, but you must contact the County Treasurer to learn the specific sale date for the property or properties you are interested in. Sales dates may change, so always confirm directly with the Treasurer before the scheduled date.

How long is the redemption period in Colorado, and can the original owner take back the property after I buy it?

Yes. Colorado law grants the original owner and certain lien holders a statutory right to redeem the property after a tax sale. The exact length of the redemption period depends on the circumstances and must be confirmed with the County Treasurer for your specific property. During redemption, the original owner can reclaim the property by paying the winning bid amount plus interest and costs. Once the redemption period expires, you receive a deed and own the property free from the tax title, subject to surviving liens and occupancy rights.

Is buying a tax-delinquent property in Costilla County worth the risk?

It depends on the specific property, its condition, its liens and encumbrances, and your investment timeline. Costilla County currently has only 1 property in active tax delinquency, meaning opportunities are rare and competition will be minimal when one does come to auction. The low volume may allow you to negotiate directly with owners or to acquire a property without fierce bidding. However, you must perform thorough due diligence, inspect the property, search the title, and confirm all legal and financial terms with the County Treasurer before committing funds. For most buyers, the risks are manageable only if you do the work up front.
