How To Sell A House With Delinquent Property Taxes In Colorado

Delinquent property taxes don’t announce themselves. One year the property tax bill slips through the cracks, maybe during a job loss or a health crisis. By the time you catch it, two or three years of unpaid taxes are sitting on your property, and the weight only gets heavier. I’ve sat at a lot of kitchen tables across the Front Range with sellers in that exact spot. “I didn’t know it had gotten this bad,” they tell me, and they mean it.

Good news: you have more options than you think, and most of them don’t require a lawyer or a miracle.

What Is a Tax Lien Sale in Colorado?

Not long ago, I helped a family in Arvada sort through something that had been building quietly for two years. An elderly parent had moved into a memory care facility. The adult children were juggling jobs and kids of their own, and nobody caught the property taxes going unpaid. By the time they called me on a Thursday, the county had already sold the tax lien to a private investor at the annual sale. Ownership of the house still belonged to their parent. A clock was ticking, though, and redemption windows close quicker than families expect.

That’s the core of a tax lien sale in Colorado. When property taxes go unpaid, the county treasurer doesn’t just sit on the tax debt. Public tax lien auctions and redemptions are governed by Colorado Revised Statutes, Title 39, Articles 11 and 12. Every year, unpaid taxes on real estate, mobile homes, minerals, and special assessment properties are sold to investors. County coffers get their money. An investor gets a certificate of purchase. You still own your home, but someone else now owns the right to collect what you owe, with interest. Nothing about that sale changes whose name is on the deed.

Buying a tax lien at the sale gets an investor a property tax lien and nothing else. No property rights come with it, and the property still belongs to the assessed owner through the redemption period. That distinction matters. A lien investor isn’t your landlord and can’t move into your house. What they can do is wait, collect interest, and eventually apply for a Treasurer’s Deed if you never redeem.

How Do Colorado Tax Lien Sales Work?

Liens sold in Colorado this year carry an annual rate of 13%, which works out to 1.08% added every month the lien sits unpaid. The number isn’t fixed forever. Each year’s rate lands nine percentage points above the federal discount rate in effect on September 1, rounded to the nearest full percent. So it resets every fall. What you’d owe to redeem a lien in El Paso County today can differ from the rate riding on a certificate bought three years ago.

Sales happen county by county, on schedules each county treasurer sets. Adams County ran its 2025 sale from October 20 through 31, covering 2024 taxes payable in 2025. Denver, Jefferson, and other metro counties follow similar timelines, usually in the fall. Adams County’s tax lien sale is an internet sale, so bidders compete from wherever they have a laptop.

Here’s where plenty of articles get Colorado wrong. Investors don’t bid the interest rate down. The state sets the rate, and counties run premium auctions instead, where bidders offer more than the taxes owed to win the certificate. Premiums earn no interest and never come back. So the winning investor is betting you redeem, because that’s how the return shows up. Most lien holders want their money, not your house.

Colorado Delinquent Property Tax List: How to Find It

A seller once called me after finding her own address in the newspaper. She hadn’t known about the publication requirement until a neighbor mentioned it. The delinquent property tax list in Colorado really is that public. Plenty of owners only learn about the exposure once it’s already out there.

Most Colorado counties post the delinquent tax list on the treasurer’s website ahead of the sale, and some refresh it as often as nightly. The same list runs in local newspapers before properties reach the tax lien sale. In El Paso County, the taxes available at the tax lien sale are advertised for three consecutive weeks beforehand in the Colorado Springs Gazette.

Denver owners can pull payment history, due dates, and delinquencies from the Denver County Treasurer. The Colorado Department of Local Affairs Division of Property Taxation is the state-level resource for how assessment and collection actually work. In Jefferson County, ask the Treasurer’s office directly for the list of liens struck to the county. The annual tax lien sale there runs in November.

Colorado Tax Lien Sale Notices and Public Records

I used to assume a lien could sell at auction with no real warning to the owner. Colorado law requires public notice well before the sale, and the process is more transparent than people give it credit for.

On the income tax side, the Colorado Department of Revenue has to disclose a list of delinquent taxpayers who’ve owed more than $20,000 for longer than six months. Anyone who meets that description gets a letter first, warning that an unresolved tax delinquency could put their name on the list. That list is separate from the property tax lien process. It’s still a fair illustration of how openly Colorado tracks tax debt.

Property tax records work the same way, and they run the whole system. County assessor and treasurer records are public and legally binding, so the tax delinquency facts are what they are. The moment a lien certificate is issued, it becomes a public record attached to your title. Any title search will surface it. A buyer using a mortgage will have a lender pulling that information before closing. Check the Department of Revenue’s delinquent taxpayer disclosure page for the income tax side, and your county assessor’s site for property tax records. If you want to know how a lien actually gets cleared at the closing table, here’s what happens when you sell a house with a lien in Colorado.

What Are You Buying at a Colorado Tax Lien Sale?

Get this wrong, and you’ll spend years thinking you own something you don’t. Investors at a Colorado tax lien sale sometimes act like they bought the property. They didn’t.

A tax lien hands over no ownership, no possession, no right to use or improve the place, not even the right to walk onto it. The investor holds a Tax Lien Sale Certificate of Purchase, a recorded claim that earns interest. The original owner keeps title. The lien holder’s claim is purely financial. They paid the county, and they’re owed that money back with interest when you redeem. If you don’t, they can start the Treasurer’s Deed process.

Property tax liens outrank everything else on title. Mortgages and deeds of trust get wiped out if an owner loses the home at the end of a tax sale process. That’s the dangerous part. If you have a mortgage on a home with a delinquent property tax lien, your lender may pay the property taxes and roll the amount into your loan balance. Now you’ve got a bigger mortgage and an unhappy servicer. Lien priority isn’t a technicality. It’s why lenders watch this so closely.

What Happens After You Purchase a Tax Lien in Colorado?

Sellers ask me whether the window closes once an investor buys the lien. It doesn’t. The three-year redemption period is the whole point of the system.

You get three years from the tax lien sale to redeem. Redeeming means paying everything owed: the original delinquent taxes, any later taxes the certificate holder endorsed onto the certificate, plus interest accrued from the sale date through the day you pay. The investor then collects a check for what they put in plus what it earned, sometimes years later.

Colorado also gives the holder room to wait. A certificate of purchase stays good for 15 years, and each new year of unpaid property taxes can be endorsed onto it at the same rate. A lien on your property can sit quietly while the redemption balance climbs, then move quickly. Ask the county when the lien was sold and whether later property taxes have been endorsed onto it.

After three years, an unredeemed tax lien certificate lets the holder apply for a Treasurer’s Deed. Since House Bill 24-1056 took effect on July 1, 2024, that application no longer hands them your house. It triggers a public auction of the option for the deed, open to any bidder. If the bidding runs past the tax debt and the treasurer’s costs, the overbid goes first to junior lienholders who filed to redeem, and anything left goes to you. A U.S. Supreme Court ruling on excess proceeds forced that change. Your right to redeem also survives until the auction itself, which is later than most people assume. Selling before that date keeps you in charge instead of a bidder you’ve never met. I’d rather see you start early than late. It’s the same race against a calendar you’d face selling your house during foreclosure in Colorado, where moving before the auction date is what protects your equity.

What Are the Risks of Buying Tax Liens in Colorado?

On paper, it looks clean. Pay the delinquent property taxes, earn a guaranteed rate, then collect when the owner redeems or take a shot at the property after three years. Routt County’s own website compares the investment to a long-range certificate of deposit. In Routt County, eventual transfer of deed has happened in less than one percent of all liens bought. Most of the time, nobody gets a house out of it.

The complications are real, though. Properties can carry senior liens, environmental problems, or title defects that nobody sees until the deed process starts. Any subsequent property tax liens have to be brought current before a deed issues. An investor who paid a premium at auction can’t recoup it when you redeem, so overpaying carries no safety net. They also can’t inspect the property first. Walking onto it before a Treasurer’s Deed issues can count as trespassing, and several county treasurers say so in writing. For homeowners, the useful part is this: lien investors will often negotiate a payoff, accept a short sale, or work out terms that let you walk away clean. You can use that.

How to Sell a House with Delinquent Property Taxes in Colorado

Selling is usually the fastest and cleanest way out, precisely because the lien holder wants cash instead of your property. A property tax lien on title doesn’t block a sale of your Colorado home. It just has to be resolved at closing, and the sale proceeds normally cover it, which leaves the buyer with clear title.

As of July 2026, the Colorado median home price was $557,992, with homes sitting a median of 49 days on the market statewide. In the Denver metro, the median closed price was about $595,000 in August 2026, and homes went under contract in a median of 29 days. Prices like that mean plenty of Colorado homeowners hold equity even with tax debt stacked on top. Owe two or three years of property taxes on a home that’s appreciated, and you can often sell, clear the lien, cover closing costs, and still walk away with money.

Look at what’s sold near you before you trust a statewide number. Two homes carrying identical delinquent property taxes can leave two sellers with very different equity. Markets differ the same way across the Front Range, so if the house sits in Boulder County, here’s how we buy houses in Boulder, CO.

How you sell matters just as much. A traditional listing takes time: finding an agent, prepping the home, negotiating a contract, then waiting on the buyer’s lender. Three to four months is common. If your redemption window is short, that math deserves a hard look.

Worth knowing how the payoff lands. Your title company orders a redemption figure from the county treasurer, the amount shows up on the settlement statement, and the delinquent property taxes get paid out of sale proceeds the day you sign. Nobody hands you a bill to cover first. If the lien was sold to a private holder, that payoff goes to them instead of the county, and it includes the interest earned since the sale date.

Selling directly to a local home buyer like LVN Real Estate moves faster. We buy as-is, so there’s no repair list and no weekend of open houses. The lien gets paid at closing out of sale proceeds. I’ve watched sellers hold firm on price, lose the offer, and land somewhere worse six months later. A slightly lower cash offer that closes in two or three weeks, clears your lien, and stops the redemption interest clock usually beats the alternative.

Who Do You Contact About Tax Liens in Colorado?

Start with your county treasurer’s office. Not a website, not a forum. They hold the records, know what’s owed, and in most Colorado counties will give you a payoff figure over the phone or by email.

Every county in Colorado runs its own tax lien sale process and keeps its own records. The El Paso County Treasurer handles liens around Colorado Springs, and if that’s where your house sits, here’s how we buy houses in Colorado Springs. Jefferson County homeowners can call the treasurer’s office at the number on the county’s delinquent properties page. For Denver-area property, the Denver County Assessor and Treasurer is your first call.

If a private investor already holds your lien, the treasurer can usually tell you who holds the lien and what the current redemption amount runs. A real estate attorney can then check whether junior liens, HOA dues, or other encumbrances need handling before closing, so you’re not walking into title work blind. LVN Real Estate works through these situations regularly and can point you toward the right title company and legal help.

Calling your county treasurer costs nothing. Waiting three more months can cost thousands in interest.

Colorado Tax Lien Sale Quick Reference and Resources

Colorado’s tax lien sale calendar isn’t the same in any two counties, which trips up first-time buyers. Dates, bidding format, and the auction platform all vary. Counties use several different auction vendors, so Broomfield, Boulder, and San Juan County won’t look alike even though the statutes behind them match.

Public tax lien auctions and redemptions are administered by the treasurer’s office in each county under Title 39. Statewide rules, local procedures.

Here are the resources worth knowing:

• Colorado Department of Local Affairs Division of Property Taxation: state-level explanation of how property tax administration works across all 64 Colorado counties.
• El Paso County Treasurer Tax Lien Sale page: a detailed local example, including the interest rate formula.
• Adams County Tax Lien Sale: covers the northern Denver metro, with online registration details.
• Broomfield City and County Tax Lien Sale Information: useful on redemption and certificate mechanics.
• Nolo’s Colorado Delinquent Property Tax Guide: plain-language summary of the statutes and what happens at each stage.

Some owners find out late and by accident. A homeowner I worked with in Commerce City had been renting the place out and storing equipment in the garage for years, unaware the property taxes had lapsed. We sorted it out on a Tuesday. There was still enough equity to cover the lien, the back interest, and closing costs, with money left over.

Frequently Asked Questions

What Happens When You Buy a House with Delinquent Taxes?

Buying a home with delinquent property taxes means taking on the job of clearing them as part of the transaction. In most sales, the outstanding property taxes and interest get paid at closing from the seller’s proceeds, so the buyer receives clear title. If the taxes were already sold to a lien investor, the title company coordinates payoff to that certificate holder directly. Have your real estate attorney and title company confirm every tax obligation is resolved before the deed transfers to you.

How Long Can the State of Colorado Collect Back Property Taxes?

Colorado’s process is time-bound but not forgiving. Unpaid property taxes become eligible for a tax lien sale, and once that lien sells, you have three years before the certificate holder can apply for a Treasurer’s Deed. That three-year redemption period is the key window. It applies no matter how many years of back taxes are involved, so long as the original certificate stays unredeemed. Colorado doesn’t write off unpaid property taxes with age either. The lien keeps earning interest until somebody pays it or the property changes hands through a Treasurer’s Deed. Your county treasurer’s office can tell you where your property sits on that timeline.

Can I Sell a House If I Owe Back Taxes in Colorado?

Yes. Back taxes don’t prevent a sale in Colorado; they just have to be satisfied at or before closing. Usually the title company handles it, paying the lien holder from sale proceeds before anything reaches the seller. If what’s owed exceeds what the sale would net, that’s a harder situation, though a direct buyer or a negotiated short sale with the lien holder can still open a path.

Do I Have to Pay Capital Gains When I Sell My House in Colorado?

It depends on how long you’ve owned the home and how you’ve used it. The federal exclusion covers up to $250,000 in capital gains for single filers and up to $500,000 for married couples filing jointly. To qualify, the home has to be your primary residence. You also need two years of ownership within the five years before the sale, and you must have lived in the property for two of those five years. Without that exclusion, Colorado taxes capital gains as ordinary income at its flat rate of 4.4%. A tax professional can tell you whether any state-level exclusions fit your situation.
