Tax Lien

A tax lien is a legal claim placed on real property by a county, municipality, or other taxing authority when the property owner fails to pay their property taxes. Tax liens occupy a unique position in the lien hierarchy: they carry super-priority status, meaning they sit ahead of every private lien on the property — including first-position mortgages and deeds of trust. For mortgage note investors, unpaid property taxes represent one of the most dangerous and most preventable risks in the business.

How Tax Liens Work

When property taxes go unpaid, the taxing authority follows a predictable escalation sequence:

1. Taxes become delinquent. The property owner misses one or more annual or semi-annual tax payments.
2. A tax lien is recorded. The county places a lien against the property for the unpaid amount plus penalties and interest.
3. A tax sale occurs. The county sells either a tax lien certificate (the right to collect the debt) or the property itself at auction, depending on state law.
4. A redemption period runs. The property owner — and in many states, lien holders of record — have a statutory window to pay the delinquent taxes plus fees and redeem the property.
5. A tax deed is issued. If no one redeems, ownership transfers to the tax sale purchaser free and clear of all prior liens, including mortgages.

That final step is what makes tax liens catastrophic for note investors. When a tax deed is issued, your promissory note becomes unsecured — the collateral that backed your investment is gone.

Tax Lien States vs. Tax Deed States

The mechanics of how a county collects delinquent taxes vary by jurisdiction. Understanding which system applies in the state where your collateral is located directly affects your risk assessment.

Why Tax Liens Matter for Note Investors

Tax liens outrank every private lien regardless of recording date. A $450 delinquent tax bill can — and does — wipe out a $7,000 non-performing loan investment backed by a $33,000 property. This is not theoretical; it is one of the most common ways note investors suffer total losses. The amounts involved are almost always small relative to the value being destroyed.

The Priority Stack

First Liens vs. Junior Liens

Counterintuitively, first-position note holders are more exposed to tax wipes than junior lien holders. When you hold a second-position note, the senior lien holder typically monitors and pays delinquent taxes to protect their own collateral — indirectly protecting yours. When you hold a first-position note, there is no one in front of you watching the tax status.

How to Protect Your Investment

Tax foreclosure losses are entirely preventable. Build these practices into your workflow:

• Check tax status during due diligence. Verify the property's tax status through the county tax portal before you bid. Look for delinquent balances, sold certificates, and approaching redemption deadlines.
• Monitor taxes on every asset you own. Confirm that your servicer is tracking tax status. On non-performing notes where no escrow payments are being collected, no one is paying the taxes unless you advance the funds yourself.
• Pay delinquent taxes immediately. Add the amount to the borrower's outstanding balance. The cost of advancing a few hundred dollars in taxes is negligible compared to losing your entire investment.
• Respond to tax sale notices as a top priority. If a tax certificate has been sold, you typically have a redemption window to pay the delinquent amount plus penalties and interest. Once that window closes, the right to redeem is gone.
• Prioritize deceased borrower accounts. A living borrower with equity has every incentive to pay a small tax bill. A deceased borrower cannot. These accounts require active monitoring and faster resolution timelines.
