Tax Sale vs Sheriff Sale: What's the Difference for Investors?

If you're looking to buy property at a discount, you'll encounter two main types of auctions: tax sales and sheriff sales. They sound similar — both sell real estate to the highest bidder — but the underlying mechanics, risks, and opportunities are very different. Choosing the wrong auction type for your strategy can be an expensive mistake.

Starting bid	Amount of delinquent taxes owed	Outstanding mortgage balance (usually)
Typical discount	60–90% below market value	10–30% below market value
Redemption period	0–3 years (varies by state)	0–12 months (varies by state)
Competition level	Moderate	High (banks, hedge funds, flippers)
Capital needed	$100–$5,000 per lien/deed	$10,000–$200,000+
Interior access	No (buy sight-unseen)	No (buy sight-unseen)

What Is a Tax Sale?

A tax sale happens when a property owner fails to pay their property taxes for a period of time (typically 1–5 years, depending on the state). The county government needs that tax revenue, so it sells either the delinquent tax debt (as a tax lien certificate) or the property itself (as a tax deed) to investors at public auction.

Tax Lien Sales

In roughly 30 states, the county sells the tax debt as a certificate. You pay the back taxes, and the owner owes you the amount plus interest (8–36% depending on state). If the owner doesn't pay within the redemption period, you can foreclose and take the property.

Tax Deed Sales

In the remaining states (including Texas, Georgia, and California), the county sells the property itself. Bidding typically starts at the amount of delinquent taxes owed. In Texas, the winning bidder receives a redeemable deed — the owner has 6 months to 2 years to buy the property back at a 25–50% penalty. Other states issue absolute deeds with no redemption.

Key advantage of tax sales: The starting bid is based on taxes owed, not the mortgage balance or property value. This means a $200,000 house with $5,000 in back taxes could theoretically sell for as little as $5,000. In practice, competitive bidding pushes prices higher, but discounts of 50–90% are common.

What Is a Sheriff Sale?

A sheriff sale (also called a foreclosure sale or trustee's sale) happens when a homeowner defaults on their mortgage. The lender files a foreclosure action in court, and if the court approves, the property is sold at a public auction conducted by the county sheriff.

How it works:

1. Borrower stops making mortgage payments (typically 3–6 months of missed payments)
2. Lender files a lis pendens (notice of pending litigation) and begins foreclosure proceedings
3. Court grants a judgment of foreclosure
4. Property is advertised and sold at public auction by the sheriff
5. Winning bidder receives a sheriff's deed

Key difference: The opening bid at a sheriff sale is typically the outstanding mortgage balance plus legal fees. If the owner owes $180,000 on a $200,000 house, the opening bid is around $180,000 — not the $5,000 in back taxes. This dramatically changes the economics.

Price Comparison: What You'll Actually Pay

Property Value	Tax Sale Starting Bid	Sheriff Sale Starting Bid
$100,000	$1,500–$8,000 (taxes owed)	$75,000–$95,000 (mortgage balance)
$200,000	$3,000–$15,000	$150,000–$190,000
$500,000	$5,000–$30,000	$350,000–$480,000

The discount at sheriff sales typically comes from properties where the market value has dropped below the mortgage balance, or where the property needs significant repairs that reduce its value below the opening bid. When no third-party bidder meets the opening bid, the lender takes the property back (becoming an REO — real estate owned) and may sell it later at a discount.

Which Liens Survive Each Sale?

This is one of the most critical and misunderstood aspects of property auctions:

Tax Sales

Tax liens have super-priority — they generally wipe out all other liens, including mortgages. When you buy at a tax sale, you typically receive the property free and clear of most encumbrances. Important exceptions:

• IRS federal tax liens (120-day redemption right)
• Some HOA liens (varies by state)
• Environmental liens (CERCLA)
• Certain government liens (special assessments)

Sheriff Sales

Sheriff sales only wipe out liens junior to the foreclosing lien. If a first mortgage forecloses, junior liens (second mortgages, HELOCs, judgment liens) are wiped out. But if a junior lienholder forecloses, the senior mortgage survives — and you're now responsible for it.

Critical warning: If you buy at a sheriff sale where a second mortgage is foreclosing, the first mortgage (which could be $200,000) stays on the property. You just bought a house with a $200,000 loan you didn't know about. This mistake has destroyed investors.

Risk Comparison

Risk Factor	Tax Sale	Sheriff Sale
Title issues	High — quiet title often needed	Lower — court-supervised process
Hidden liens	Low — tax liens have super-priority	High — senior liens may survive
Redemption risk	Moderate — 6 months to 3 years	Low to moderate — 0 to 12 months
Property condition	High risk — often long-abandoned	Moderate — recently occupied
Occupant issues	Moderate — may need eviction	Moderate — may need eviction
Overpaying risk	Low — starting bids are small	Higher — starting bids near market value

Which Is Better for Your Strategy?

Choose Tax Sales If:

• You have limited capital ($500–$10,000)
• You want to build a portfolio of lien certificates earning interest
• You're comfortable with longer timelines (1–3 years for redemption/foreclosure)
• You're willing to deal with title cleanup work
• You want access to properties at the steepest discounts

Choose Sheriff Sales If:

• You have significant capital ($50,000+)
• You want properties you can flip or rent quickly
• You prefer court-supervised transactions with clearer title
• You have experience with rehab and property management
• You're buying in a market where property values are stable or rising

Can You Do Both?

Absolutely, and many experienced investors do. A common strategy is to use tax lien certificates as your "fixed income" allocation — earning 8–16% on relatively safe certificates — while selectively pursuing sheriff sale properties for larger one-time profits.

The two markets don't compete with each other for your attention either. Tax sales happen on a fixed annual schedule (usually once per year per county), while sheriff sales happen continuously throughout the year as individual foreclosures are processed by the courts.

How to Find Properties for Each Auction Type

Tax sale properties:

• County treasurer/tax collector websites (official delinquent lists)
• LienSuite county database — tax delinquent properties with property data, owner info, and scoring
• Online auction platforms (Bid4Assets, GovEase, RealAuction)

Sheriff sale properties:

• County sheriff's office website
• Legal newspapers and public notices
• Auction.com, Hubzu, and similar foreclosure platforms
• Court records (lis pendens filings)

The Bottom Line

Tax sales and sheriff sales are both legitimate paths to discounted real estate, but they require different strategies, different capital, and different risk tolerance. Tax sales offer deeper discounts and lower barriers to entry, while sheriff sales offer properties in better condition with cleaner title.

If you're just getting started, tax sales are generally easier to learn with less money at risk. You can start researching tax delinquent properties for free on LienSuite to understand what's available in your area before committing capital to your first auction.
