Buying tax delinquent property in Texas can be one of the most profitable real estate strategies—if you know the process. Properties sell at 20-50% below market value, but the path from finding a property to owning it has specific steps that trip up newcomers.

This guide walks you through exactly how to buy tax delinquent property in Texas, from initial research through closing. Follow these steps and you'll be prepared for your first tax sale.

Overview: Two Paths to Tax Delinquent Property

There are two main ways to acquire tax delinquent property in Texas:

1. Buy at Tax Sale (Auction)

Properties with unpaid taxes are sold at public auction on the courthouse steps. You bid against other investors, pay that day, and receive a deed. This is the most common method.

2. Buy Directly from Owner (Pre-Foreclosure)

Contact owners of tax delinquent properties before the tax sale and negotiate a direct purchase. You pay off the taxes as part of the deal. This avoids auction competition but requires more outreach.

This guide covers both approaches, with emphasis on the tax sale process since that's where most investors start.

Step 1: Find Tax Delinquent Properties

Before you can buy, you need to find properties. Here's where to look:

County Tax Assessor-Collector Websites

Each Texas county posts tax sale lists before monthly auctions. These lists show:

Property address and legal description
Amount owed (minimum bid)
Owner name
Sale date and time

Tax sales occur the first Tuesday of each month in most counties. Lists are typically posted 21 days before the sale.

County Appraisal District Data

For broader research beyond just upcoming sales, use county appraisal district (CAD) data:

Harris County (HCAD) — hcad.org
Dallas County (DCAD) — dallascad.org
Tarrant County (TAD) — tad.org
Bexar County (BCAD) — bcad.org
Travis County (TCAD) — traviscad.org

These sites provide property values, ownership history, and tax status. Many offer bulk data downloads for serious researchers.

Delinquent Tax Rolls

Some counties publish complete lists of all delinquent properties, not just those scheduled for sale. This is gold for finding pre-foreclosure opportunities where you can approach owners directly.

Property Data Aggregators

Services like Liensuite aggregate data from multiple counties, normalize it into searchable format, and help identify the best opportunities. This saves dozens of hours compared to manual county-by-county research.

Pro Tip: Look Beyond the Sale List

Properties on the tax sale list have the most competition. For better deals, identify properties that are delinquent but not yet scheduled for sale. Contact owners directly—many will sell to avoid foreclosure.

Step 2: Research Properties Thoroughly

Never bid on a property you haven't researched. Due diligence before the auction prevents expensive mistakes after.

Title Research

A tax sale doesn't wipe out all liens. Before bidding, check for:

Federal tax liens (IRS) — Survive tax sale for 120 days
Other tax liens — State, municipal
HOA liens — May survive in some cases
Mortgage liens — Usually wiped out, but verify
Judgment liens — Usually wiped out

Order a title search or check deed records at the county clerk's office. For properties you're serious about, a preliminary title report from a title company costs $150-300 and is worth every penny.

Property Research

Understand what you're buying:

Property type — Residential, commercial, land, etc.
Size and features — Square footage, lot size, bedrooms/baths
Condition — Drive by or view on Google Street View
Occupancy — Is someone living there? (Adds complexity)
Flood zone status — Check FEMA maps
Zoning — Verify permitted uses

Value Analysis

Determine what the property is worth:

Comparable sales — What have similar properties sold for?
CAD appraised value — Starting point, often below market
Repair estimates — Factor in needed work
ARV (After Repair Value) — What's it worth fixed up?

Calculate Your Maximum Bid

Work backwards from value to determine your ceiling:

Calculation	Example
After Repair Value (ARV)	$150,000
Less: Repair costs	-$20,000
Less: Holding costs (6 months)	-$5,000
Less: Selling costs (8%)	-$12,000
Less: Desired profit	-$30,000
Maximum bid	$83,000

Set this number before the auction and don't exceed it, no matter how competitive bidding gets.

Step 3: Understand the Redemption Period

Texas gives former owners a chance to reclaim their property after a tax sale by paying the purchase price plus a penalty. This is called the redemption period.

Redemption Periods by Property Type

Property Type	Period	Penalty to Redeem
Homestead (owner-occupied)	2 years	25% (year 1) or 50% (year 2)
Agricultural use	2 years	25% (year 1) or 50% (year 2)
Non-homestead residential	180 days	25%
Commercial/other	180 days	25%

What This Means for You

During the redemption period:

You own the property (have the deed)
You cannot take possession or make improvements
You cannot rent it out
You're essentially holding a secured note

If the owner redeems:

You get your purchase price back
Plus the 25% or 50% penalty
Guaranteed return with no property risk

If the owner doesn't redeem:

You take full possession after the period expires
You can then improve, occupy, or sell

Strategic Implications

Some investors prefer redemption—a guaranteed 25-50% return is excellent. Others specifically target non-homestead properties for the shorter 180-day period. Know your strategy before bidding.

Step 4: Prepare for the Auction

Tax sales in Texas happen at the county courthouse on the first Tuesday of each month. Here's how to prepare:

Registration Requirements

Each county has slightly different rules, but generally you need:

Valid government ID
Completed bidder registration form
Some counties require pre-registration

Check with the specific county's tax office for their requirements. Arrive early on sale day—registration often closes before bidding starts.

Payment Requirements

Texas tax sales require payment the same day, typically within hours of winning. Accepted forms of payment vary by county but usually include:

Cash
Cashier's check or money order
Certified funds

Personal checks and credit cards are not accepted. Come prepared with enough funds to cover your maximum bid on all properties you're interested in.

What to Bring

Government-issued ID
Certified funds / cashier's checks
Your property research notes
List of properties and maximum bids
Calculator
Patience (auctions can take hours)

Scout the Location

Visit the courthouse before sale day to know:

Where the auction is held
Where to park
Where to register
The general flow of the process

Step 5: Bid at the Auction

Auction day. Here's what to expect and how to succeed:

How the Auction Works

Properties announced — Auctioneer reads property info and minimum bid
Bidding opens — Starts at minimum bid (taxes + penalties + fees)
Competitive bidding — Bidders raise until one remains
Property sold — Highest bidder wins
Payment due — Winner pays immediately or within hours

Bidding Strategies

Start strong or wait? Different investors have different approaches:

Aggressive opening — Bid your maximum immediately to discourage competition
Wait and see — Let others bid, jump in only if it stays below your max
Incremental — Bid in small increments to not reveal your ceiling

There's no universally "best" approach. What matters is knowing your maximum and not exceeding it.

Common Auction Mistakes

Auction fever — Getting caught up and overbidding
Bidding on unresearched properties — "It seemed like a good deal"
Insufficient funds — Winning but can't pay
Wrong property — Bidding on the wrong parcel number

If You Win

After winning a bid:

Complete payment as directed (usually within 1-2 hours)
Receive your receipt
The deed will be prepared and recorded (takes days to weeks)
You'll receive the recorded deed by mail

If You Don't Win

Don't force it. If properties go above your maximum, let them go. There's another sale next month. Patience beats desperation.

Step 6: After the Sale

You won the auction and paid. Now what?

Wait for Your Deed

The county prepares and records the Sheriff's Deed (or Constable's Deed). This typically takes 2-4 weeks. You'll receive a copy once recorded.

Start the Redemption Clock

The redemption period begins from the date of sale (not when you receive the deed). Track this date carefully.

During the Redemption Period

Remember: you cannot take possession during this time. However, you can:

Monitor the property (from public areas)
Research title issues for post-redemption clearing
Line up contractors for future work
Plan your exit strategy

If the Property Is Redeemed

The former owner (or someone on their behalf) pays the county. The county then:

Notifies you of the redemption
Sends you a check for purchase price + penalty
The deed is essentially voided

Redemption isn't failure—you earned 25-50% return with minimal risk.

If Not Redeemed

Once the redemption period expires:

You have full ownership rights
You can take possession
You may need to evict occupants (separate legal process)
Clear any remaining title issues
Proceed with your investment strategy

Step 7: Clear Title Issues

Tax sale deeds don't always provide perfectly clean title. Common issues to address:

Quiet Title Action

A lawsuit that establishes your clear ownership. Recommended for properties with:

Heir property complications
Unknown prior claims
Any title company concerns

Cost: $3,000 - $10,000
Time: 6-12 months

Affidavit of Heirship

If the prior owner died and you're dealing with heir issues, this sworn document can help establish the ownership chain.

Curative Title Work

Various documents and procedures to clean up specific defects. Work with a real estate attorney experienced in tax sales.

Title Insurance

Most title companies won't immediately insure a tax sale deed. After clearing issues (or waiting several years), you can obtain title insurance, which is necessary for resale to conventional buyers.

Alternative: Buy Directly from Owners

Instead of competing at auction, you can purchase directly from owners of tax delinquent property before the sale.

Finding Owners

Use delinquent tax lists to identify properties, then:

Send direct mail to owners
Skip trace to find contact information
Door knock (if local)
Search for heirs if owner is deceased

The Pitch

Owners of tax delinquent property are often motivated:

They can't afford the taxes
They've inherited property they don't want
They've moved away
They're facing foreclosure

Offer to solve their problem: you buy the property, pay off the taxes, and they walk away with cash.

Structuring the Deal

Typical direct purchase structure:

Negotiate purchase price with owner
Sign purchase agreement
Pay delinquent taxes at closing
Receive warranty deed (stronger than tax deed)
Get title insurance (much easier than tax sales)

Advantages of Direct Purchase

No auction competition — You set the price
Warranty deed — Better than Sheriff's deed
Title insurance available — Easier to resell
No redemption period — Immediate possession possible
Can negotiate terms — Seller financing, delayed closing, etc.

Disadvantages

More work — Finding and contacting owners takes time
Lower response rates — Many owners don't respond
Negotiation required — You're dealing with people, not an auction

Common Mistakes to Avoid

1. Skipping Due Diligence

The biggest mistake. Never bid on a property you haven't researched. That "great deal" might have a $50,000 IRS lien or be in a flood zone.

2. Ignoring the Redemption Period

Planning to flip a homestead property in 6 months? You can't—there's a 2-year redemption period. Know the timeline before bidding.

3. Overbidding

Auction psychology is real. Set your maximum before the sale and stick to it. There will always be another property.

4. Underestimating Title Work

Budget for title clearing. A quiet title action can cost $5,000-$10,000. Factor this into your maximum bid.

5. Forgetting About Occupants

If someone is living in the property, you'll need to deal with them. Eviction in Texas takes 1-3 months and costs $1,500-$3,000. Factor this into your analysis.

6. Not Having an Exit Strategy

Before you bid, know your plan: flip, rent, wholesale, or hold. Each strategy has different requirements for property type and condition.
