Property Tax Lien

A property tax lien is a lien that a local government places on real estate when the owner fails to pay property taxes. It secures the unpaid taxes against the property and, crucially, almost always holds super-priority — meaning it ranks ahead of essentially all other liens, including a first-lien mortgage or deed of trust. Because a property tax lien can leapfrog even the most senior private lien, it is one of the most important risks for anyone holding or buying a mortgage note.

How property tax liens arise and are enforced

• Automatic attachment: In most jurisdictions, unpaid property taxes become a lien on the property by operation of law, often as of a set date each year — no court action required.
• Tax sale / tax deed: If taxes stay unpaid, the government can ultimately sell the tax debt (a tax lien certificate) or the property itself (a tax deed) at a public auction to recover what's owed. In some states the delinquent owner has a redemption right to reclaim the property by paying the taxes plus interest and costs.
• Priority: Because government depends on tax revenue, statutes give property tax liens priority over private liens regardless of recording date.

Why property tax liens are so dangerous to note holders

The super-priority is the heart of the issue. Even a holder of a pristine first-lien note can be wiped out — or forced to pay the back taxes to protect its position — if the borrower stops paying property taxes and a tax sale proceeds. This is exactly why many mortgage notes require an escrow/impound account for taxes, and why lenders monitor tax payment status. An unpaid property tax lien quietly erodes the equity that protects the note and can, in a worst case, eliminate the lien entirely through a tax foreclosure.

Why it matters when you buy or sell a note

Property tax status is a top item in note due diligence:

• Verify taxes are current. A title search and a tax certificate confirm whether property taxes are paid. Delinquent taxes are a senior claim that a buyer must price in — or require to be cured before closing.
• Check for an escrow. Notes with a tax escrow are lower-risk because taxes are paid automatically from the borrower's payments.
• Watch redemption timelines. If a tax sale has occurred, the redemption window and amounts matter for whether the lien can be saved.

For a note seller, demonstrating that property taxes are current — ideally with an escrow in place — directly supports a higher price and a faster sale. Delinquent taxes are among the fastest ways to lower a note's value.

Example

A note buyer is reviewing a $175,000 first-lien note. The tax certificate shows two years of unpaid property taxes totaling $9,000, with a tax sale approaching. Because the property tax lien is senior to the note's first lien, the buyer either requires the seller to bring the taxes current before closing or reduces the offer by the tax amount plus a risk buffer. Left unpaid, the taxes could lead to a tax foreclosure that extinguishes even this first-lien note.
