When a condo owner defaults on property taxes, the county records a tax lien against the unit, interest and penalties start accruing immediately, and the lien jumps ahead of the mortgage and the condo association’s claim for unpaid dues. If the debt isn’t paid, the unit can be sold at a tax sale, and that sale can wipe out both the mortgage and the association’s assessment lien. The owner can lose the unit entirely, and the fallout often reaches the other owners in the building.
The Lien Forms Fast, and It Grows
Each condo unit is its own parcel of real property, and the tax bill goes directly to the unit owner. The association has no responsibility for it. Miss the statutory deadline and penalties and interest start running on the unpaid balance. Annual interest on delinquent property taxes ranges from roughly 8% to as high as 36% depending on the jurisdiction, with most states falling between 10% and 18%. Some places tack on flat penalties as well.
The taxing authority then records a formal tax lien against the unit’s legal description in the county records. That converts an unsecured debt into a secured claim against the unit. The lien covers the delinquent taxes plus all accrued interest, penalties, and administrative fees, and it follows the property regardless of who owns it. No buyer, lender, or title company will close on a unit carrying an outstanding tax lien, so the owner is effectively locked out of selling or refinancing until the debt is cleared.
One thing the lien does not do anymore: show up on a credit report. The three major credit bureaus removed tax liens from consumer credit files by April 2018.1Consumer Financial Protection Bureau.

Why the Tax Lien Beats the Mortgage
Property tax liens sit at the top of the priority ladder. They are senior to first mortgages, second mortgages, judgment liens, and the condo association’s lien for unpaid assessments. Even the federal government defers: under federal statute, a real property tax lien that has priority under local law over prior security interests also takes priority over a federal tax lien.2Office of the Law Revision Counsel. 26 USC 6323 – Validity and Priority Against Certain Persons If the lien beats the IRS, it beats everyone.
For the mortgage lender, this means a tax lien can leapfrog a loan the bank made years earlier. For the condo association, the government gets paid first out of any forced sale, before the association sees a cent. Some states grant associations a limited super-priority lien for a few months of unpaid dues that can leapfrog a first mortgage, and the Federal Housing Finance Agency has challenged these provisions when they threaten mortgages held by Fannie Mae or Freddie Mac.3Federal Housing Finance Agency. Statement of the Federal Housing Finance Agency on Certain Super-Priority Liens Even where that super-priority exists, it only runs against mortgages. The government’s tax lien still comes first.
What the Mortgage Lender Does
Most owners with a mortgage never touch property tax payments. Federal regulations require servicers to pay tax disbursements from escrow on time, and the servicer must advance funds to avoid a penalty even if the borrower’s payment is up to 30 days overdue.4Consumer Financial Protection Bureau. 12 CFR 1024.17 – Escrow Accounts When escrow is working, a tax default is nearly impossible.
The system breaks in two ways. The escrow account may be underfunded because the tax bill jumped beyond what the servicer collected. The servicer still has to pay, then raises the monthly mortgage payment to make up the shortage. Federal rules allow the shortage to be spread over at least 12 months, but the owner’s housing cost goes up either way.4Consumer Financial Protection Bureau. 12 CFR 1024.17 – Escrow Accounts
The other scenario is simpler and more common: the borrower stopped paying the mortgage. Once the mortgage payment is more than 30 days overdue, the servicer is no longer required to advance escrow disbursements. The taxes go unpaid, and the lien clock starts. Failing to pay property taxes is itself a breach of the mortgage contract, independent of any missed mortgage payments. Standard mortgage agreements include a covenant to keep taxes current, and violating it gives the lender grounds to accelerate the full loan balance.
In practice, lenders usually pay the delinquent taxes themselves rather than let a tax lien threaten their collateral. The lender adds the amount to the loan balance and raises the escrow going forward. That protects the lender, but it can push the owner’s monthly payment past what they can afford, feeding the same spiral that leads to mortgage default and foreclosure.
Tax Sales and Redemption
If the delinquent taxes stay unpaid after the lien is recorded, the local government moves to force a resolution. The mechanism varies, but it generally takes one of two forms.
In a tax lien certificate sale, the government auctions the right to collect the debt to a private investor. The investor pays the taxes and receives a certificate entitling them to collect what’s owed, with interest, from the owner. The investor does not get the unit, the right to occupy it, or the right to collect rent. They hold a debt instrument. The owner keeps using the unit while the redemption clock runs.
In a tax deed sale, the government sells the property itself. This is more drastic and usually happens after the redemption period has expired, or in jurisdictions that skip the certificate stage. The buyer receives actual ownership, though they may still need legal action to take physical possession if the unit is occupied.
The redemption period is the owner’s final window to reclaim the unit by paying the full amount owed, including the original tax debt, accumulated interest, and any fees charged by the purchaser. These windows vary dramatically. Some jurisdictions allow as little as 60 days. Others provide one to three years, and a few extend to four. Roughly half the states that conduct tax deed sales offer no redemption period at all, meaning the sale is final immediately.
Anyone with a financial interest in the unit can redeem, not just the owner. The condo association can redeem to protect its assessment lien. The mortgage lender can redeem to protect its security interest. If no one redeems within the statutory window, the purchaser can petition the court for a tax deed. That deed extinguishes all junior liens on the unit, including the first mortgage and the association’s assessment lien. The owner loses the unit. The lender and the association lose their secured claims against it. The former owner may still owe the mortgage balance as unsecured personal debt, but the collateral is gone.
What It Costs the Rest of the Building
The association is never directly liable for a unit owner’s property tax debt. The taxing authority has no claim against the association’s operating fund or reserves. The indirect damage is another matter.
An owner who defaults on property taxes is often behind on association dues as well. The association records its own lien for the unpaid assessments, but it sits below the tax lien in priority. If the tax debt consumes all available equity in the unit, a forced sale may generate enough to satisfy the government and nothing more. The assessment lien gets wiped out, and those unpaid dues are gone for good.
The lost revenue still has to come from somewhere. The budget assumed every owner would pay their share. When one doesn’t, the board either cuts services and maintenance, draws down reserves, or levies a special assessment on everyone else. The paying owners end up subsidizing the defaulter. In a ten-unit building, a single default shifts roughly 10% of the operating budget onto the other nine. In smaller buildings, the math gets ugly quickly.
Ways Out for the Owner
Before the delinquency escalates, there are two realistic avenues worth considering.
The first is challenging the assessment itself. If the assessed value of the unit doesn’t reflect actual market value, the owner may be paying more in property taxes than the law requires. Every jurisdiction provides a formal process for contesting an assessment. The typical process involves filing a written application with the local tax commission or board of review within a set deadline, usually 30 to 90 days after the assessment notice is published. Grounds generally include an assessed value that exceeds fair market value, an assessment ratio applied incorrectly, or an exemption the assessor failed to apply. Evidence usually means comparable sales data, an independent appraisal, or documentation of conditions that reduce value. A successful challenge won’t erase taxes that are already delinquent, but it reduces the going-forward obligation and may make the outstanding balance manageable.
The second is paying the redemption amount within the statutory window after a tax sale. Interest and fees will have piled on top of the original debt, and the amount is often substantial, but redemption is the only way to pull the unit back once a tax lien certificate or deed has been issued. If the owner can’t come up with the money, the mortgage lender or the condo association may do it to protect their own positions. That rescues the unit from the tax purchaser, but the amount the lender or association advances comes right back onto the owner’s balance.
Once the redemption period closes without payment, the options are gone. The deed transfers, the junior liens are extinguished, and whatever claims the owner once had against the property end with them.
