Reading the Lien Stack Before a Bexar County Constable Sale: A San Antonio Investor's Pre-Auction Checklist

The $87,000 Lesson at the Bexar County Courthouse

In March 2023, an investor bid $87,000 on a single-family home at the Bexar County constable sale held on the first Tuesday of the month at the county courthouse steps. The property had been foreclosed by the HOA for $4,200 in delinquent assessments. The investor assumed—incorrectly—that the HOA foreclosure would function like a tax sale and wipe the existing mortgage. Six weeks after recording the constable's deed, the investor received notice that Wells Fargo intended to proceed with its own foreclosure on the $142,000 first-lien deed of trust that remained fully intact.

The investor had failed to read the lien stack. The HOA's assessment lien, while enforceable through judicial foreclosure under Texas Property Code Chapter 209, held junior priority to the recorded deed of trust. The constable sale conveyed only the borrower's equity of redemption—which was underwater. The investor walked away from $87,000 plus closing costs.

This scenario plays out regularly in San Antonio. Bexar County processes hundreds of constable sales annually, arising from various judgment creditors: HOAs, credit card companies, mechanics' lien claimants, and ad valorem tax authorities. Each sale type carries different consequences for what liens survive. Understanding the lien stack before you bid is not optional—it's the difference between acquiring a property and acquiring a lawsuit.

How Constable Sales Work in Bexar County

A constable sale in Texas is the execution phase of a judgment. After a creditor obtains a court judgment and a writ of execution, the constable seizes the debtor's property and sells it to satisfy the judgment. In Bexar County, these sales occur on the first Tuesday of each month between 10:00 AM and 4:00 PM at the designated location—typically the Bexar County Courthouse at 100 Dolorosa Street in San Antonio.

Under Texas Property Code § 34.01 and the Texas Rules of Civil Procedure (specifically Rules 646 and 646a), the constable must post notice of sale at the courthouse door and file it with the county clerk at least 21 days before the sale date. The Bexar County Constable's Office—Bexar has eight constable precincts—maintains lists of pending sales, though the posting requirements and actual notice quality vary.

Critically, a constable sale conveys only the interest of the judgment debtor. Under Texas law, this is known as the debtor's "right, title, and interest" in the property. If the debtor's interest is encumbered by senior liens, those liens survive the sale and remain attached to the property. The winning bidder takes subject to all liens that are senior in priority to the judgment being executed.

This is fundamentally different from a tax foreclosure. Under Texas Tax Code § 34.01(n), a tax sale extinguishes all liens except for federal tax liens (which have a 120-day redemption period under 26 U.S.C. § 7425). A constable sale for a private judgment, however, does not have this sweeping effect.

The Lien Priority Framework in Texas

Texas follows a "first in time, first in right" priority system for most liens, with several critical exceptions. To read a lien stack on a Bexar County property, you must understand the priority rules that deviate from pure recording chronology.

Ad Valorem Tax Liens: The Permanent Senior Position

Under Texas Tax Code § 32.01, ad valorem property tax liens attach to property on January 1 of each year and are automatically senior to all other liens, regardless of when other liens were recorded. This means a 2024 tax lien is senior to a deed of trust recorded in 2015. If you purchase at a constable sale and the property has delinquent ad valorem taxes, you will owe those taxes plus penalties and interest, or the taxing authorities can foreclose.

In Bexar County, property taxes are collected by the Bexar County Tax Assessor-Collector for multiple taxing entities: Bexar County, the City of San Antonio (if applicable), various independent school districts (Northside ISD, North East ISD, San Antonio ISD, etc.), and special districts like the University Health System and San Antonio River Authority. Each entity's delinquent amount must be calculated separately.

As of 2024, Bexar County's combined tax rate in the City of San Antonio typically ranges from approximately $2.40 to $2.70 per $100 of assessed value, depending on the school district. A property assessed at $200,000 with two years of delinquent taxes could easily carry $10,000 or more in tax debt plus 12% per annum penalties under Texas Tax Code § 33.01.

Deed of Trust Priority: The Recording Date Controls

Mortgages in Texas are secured by deeds of trust, which are recorded in the Bexar County Clerk's Official Public Records. The priority of a deed of trust is determined by its recording date and time. A first deed of trust recorded on March 1, 2018 is senior to a second deed of trust recorded on June 15, 2020.

When you bid at a constable sale, you must identify every deed of trust recorded against the property and determine whether it is senior or junior to the judgment being executed. A senior deed of trust survives the constable sale. A junior deed of trust is extinguished—but only if the foreclosing creditor's lien was senior to it.

Mechanics' and Materialmen's Liens: The Relation-Back Doctrine

Texas Property Code Chapter 53 governs mechanics' and materialmen's liens, which secure payment for labor and materials furnished to improve real property. These liens have a "relation-back" priority under § 53.124: they relate back to the inception of the project (when visible work began or materials were first delivered), regardless of when the lien affidavit was recorded.

This creates a hidden priority issue. A contractor may record a lien affidavit in 2024, but if the work commenced in 2022—before the current deed of trust was recorded—the mechanics' lien may be senior to the mortgage. In Bexar County, where new construction and renovation activity is substantial, this doctrine can upend assumptions about lien priority.

HOA Assessment Liens: The Limited Super-Lien

Under Texas Property Code § 209.0091 (for subdivisions) and § 82.113 (for condominiums under the Texas Uniform Condominium Act), HOA and condominium associations have assessment liens that attach to a unit automatically upon delinquency. However, Texas does not grant these liens super-priority over first-lien deeds of trust.

The HOA assessment lien is junior to a recorded first deed of trust unless the HOA lien was recorded first—which almost never occurs in practice, since HOA liens arise from covenants that post-date the original financing. This is why the investor in the opening scenario lost $87,000: the HOA's judicial foreclosure via constable sale only conveyed the homeowner's equity, not the property free and clear of the mortgage.

An HOA assessment lien in Texas does have priority over junior liens (second mortgages, judgment liens) and can be enforced through either judicial foreclosure or, in some cases, non-judicial foreclosure under Property Code § 209.0092—but that enforcement does not eliminate senior encumbrances.

Judgment Liens and Abstract of Judgment

A judgment creditor who records an abstract of judgment in the Bexar County Clerk's Office creates a lien against all non-exempt real property the debtor owns in Bexar County. Under Texas Property Code § 52.001, this lien attaches as of the date and time of recording.

Multiple judgment creditors may have recorded abstracts. When a constable sale occurs to satisfy one judgment, you must determine whether other judgment liens are senior or junior to the foreclosing judgment. Senior judgment liens survive; junior judgment liens are extinguished.

Federal Tax Liens: The 120-Day Wild Card

If the IRS has recorded a Notice of Federal Tax Lien against the property owner, that lien has priority based on its recording date under 26 U.S.C. § 6323. However, federal tax liens have a critical exception: under 26 U.S.C. § 7425, the IRS has a 120-day redemption right after any non-federal sale. If the IRS exercises this right, it pays the sale price plus interest and takes the property.

In Bexar County, you must search for federal tax liens both in the county records and the state records, as liens can be filed in either location.

The Step-by-Step Lien Stack Review for Bexar County Constable Sales

Step 1: Identify the Foreclosing Party and Judgment

Obtain the case number from the constable's sale posting. In Bexar County, constable sales may arise from Bexar County District Court judgments, County Court at Law judgments, or Justice of the Peace judgments. Each court has separate records.

Search the Bexar County District Clerk's online records at apps.bexar.org/districtclerk to find the underlying case. Identify the judgment creditor, the judgment amount, and—critically—the nature of the lien securing the judgment. An HOA assessment lien judgment is treated differently than a judgment obtained by a credit card company with no underlying security interest.

Step 2: Pull the Chain of Title

Access the Bexar County Clerk's Official Public Records to review all recorded documents against the property. The Clerk's online search at apps.bexar.org/countyclerk allows searches by property address, legal description, or grantor/grantee name.

Identify:

All deeds of trust (current and released)
All assignments of deeds of trust
All subordination agreements
Any recorded mechanics' lien affidavits
Any abstracts of judgment
Any federal tax lien notices
Any lis pendens (indicating pending litigation affecting the property)

Step 3: Verify Tax Status

Access the Bexar County Tax Assessor-Collector's website at bexar.org/tax to search the property by account number or address. The tax record will show:

Current assessed value
Taxing entities
Delinquent amounts by year
Whether the property is in an active tax suit (a judicial proceeding for tax foreclosure)

If the property is already in a pending tax foreclosure, the constable sale on a private judgment may be irrelevant—the tax foreclosure will eventually extinguish your interest unless you pay the delinquent taxes.

Step 4: Check for Municipal Liens

The City of San Antonio's Code Compliance Services may have recorded liens for demolition, board-up, mowing, or other nuisance abatement. Under Texas Local Government Code § 214.001, these liens are enforceable against the property and have priority based on recording date. However, under § 214.0015, some municipal liens may have special priority over certain other encumbrances.

Contact the City of San Antonio's Development Services Department to request a lien search. As of 2024, there is no comprehensive online database for San Antonio municipal liens, so a direct inquiry is necessary.

Step 5: Identify Active Litigation

Search for any lis pendens recorded against the property. A lis pendens provides constructive notice of pending litigation that may affect title. If the property is subject to a partition suit, a divorce proceeding, or a fraudulent transfer action, your constable deed may be subject to the court's ultimate ruling.

Additionally, search Bexar County's district court and federal court (Western District of Texas, San Antonio Division) records for any bankruptcy filings. If the property owner has filed bankruptcy, the automatic stay under 11 U.S.C. § 362 may have prohibited the constable sale, making your deed voidable.

Step 6: Build the Priority Stack

Once you have all recorded encumbrances, arrange them in priority order:

Ad valorem taxes (always first, regardless of recording date)
Federal tax liens (by recording date, with 120-day redemption right)
First deed of trust (by recording date)
Mechanics' liens (by relation-back to work commencement date)
Second deed of trust or HELOC (by recording date)
Judgment liens (by abstract recording date)
HOA assessment lien (typically junior to the first deed of trust)

Determine where the foreclosing creditor's lien falls in this stack. Everything senior to that lien survives the sale. Everything junior is extinguished.

Real-World Scenario: Reading the Stack on a San Antonio Property

Consider a property at 4521 Quiet Valley Drive in San Antonio (a fictional but representative example). The constable is selling the property on behalf of a judgment creditor who obtained a $12,000 judgment for unpaid credit card debt. The abstract of judgment was recorded on August 14, 2022.

Your lien stack research reveals:

Delinquent 2022 and 2023 ad valorem taxes: $6,400 (senior to all)
First deed of trust to Freedom Mortgage: Recorded December 3, 2019, original amount $185,000 (senior to judgment lien)
Federal tax lien: Recorded February 22, 2021, amount $18,500 (senior to judgment lien)
Abstract of judgment (foreclosing creditor): Recorded August 14, 2022, amount $12,000
Second abstract of judgment (unrelated creditor): Recorded November 30, 2022, amount $8,000 (junior to foreclosing judgment—extinguished)

If you purchase at the constable sale, you acquire the property subject to:

$6,400 in delinquent taxes (plus accruing 2024 taxes)
$185,000 first deed of trust (approximately $172,000 remaining balance)
$18,500 federal tax lien (plus the IRS's 120-day redemption right)

The total encumbrance burden is approximately $196,900 before you consider the purchase price at auction. If the property's market value is $195,000, you would be acquiring negative equity. Any bid above a nominal amount would be economically irrational.

This is precisely the analysis that most novice auction bidders fail to conduct.

What TitlePin Would Have Shown

A TitlePin report on this property, pulled before the constable sale, would have flagged the critical priority issues that transform this auction from an opportunity into a trap.

TitlePin aggregates data from Bexar County's recorded documents, tax assessor records, federal lien filings, and court records into a single lien stack analysis. The report would have shown:

The first deed of trust remaining open with an estimated balance
The federal tax lien with its exact recording date and amount
The delinquent ad valorem taxes by taxing entity
The junior position of the judgment creditor's lien
A calculated "bid ceiling"—the maximum economically rational bid given surviving encumbrances

Instead of conducting six separate searches across multiple county and federal databases, the investor would have seen a unified title picture showing that the foreclosing creditor's judgment lien was fifth in priority, subordinate to nearly $200,000 in senior encumbrances.

TitlePin's pre-auction reports are specifically designed for constable sales, tax sales, and trustee sales—situations where standard title insurance underwriting (which occurs post-acquisition) cannot protect you from overpaying at auction.

Common Errors at Bexar County Constable Sales

Assuming All Foreclosure Sales Work Like Tax Sales

Tax sales under Texas Tax Code Chapter 34 extinguish most liens. Constable sales under Rules of Civil Procedure 646 and 646a do not. This fundamental distinction causes more investor losses than any other misunderstanding.

Ignoring Federal Liens

Investors often search only county records and miss federal tax liens filed at the state level or IRS redemption rights. The 120-day redemption period means your ownership is contingent for four months after acquisition.

Failing to Calculate the Realistic Balance on Deeds of Trust

The original loan amount on a recorded deed of trust does not reflect the current balance. A $200,000 loan from 2015 may have a current balance of $165,000—or it may have been refinanced without the new lender recording a release. You must verify whether the deed of trust is still active and estimate the current balance.

Missing Mechanics' Liens

Mechanics' lien affidavits can be recorded up to four months after the last work (or up to three months for certain retainage claims under Property Code § 53.057). A constable sale may occur while a contractor still has time to perfect a lien that relates back to a date senior to other encumbrances.

Disregarding Municipal Code Violations

A property with active code violations may have unreleased municipal liens or pending demolition orders. In San Antonio, a structure deemed "dangerous" under § 214.001 can be demolished by the city, with costs becoming a lien on the land.

Key Takeaways

A Bexar County constable sale conveys only the judgment debtor's interest, subject to all senior liens. Unlike a tax sale, it does not extinguish mortgages, senior judgments, or federal liens.
Ad valorem tax liens are always senior in Texas, regardless of recording date. Check the Bexar County Tax Assessor-Collector's records before every auction.
HOA assessment liens in Texas do not have super-priority over first deeds of trust. An HOA foreclosure via constable sale transfers only the homeowner's equity—not the property free of the mortgage.
Federal tax liens carry a 120-day IRS redemption right under 26 U.S.C. § 7425. Your title is contingent until that period expires.
Build the complete lien stack before bidding. Aggregate data from the county clerk, district clerk, tax assessor, city code compliance, and federal records to determine the true cost of acquisition.
