Free Cobb County Tax Delinquent Property List: Where to Find It

Cobb County is one of the easier metro Atlanta counties to research for free -- the Tax Commissioner publishes both a delinquent tax list and an excess funds list, and both are refreshed monthly. But two structural quirks trip up almost every investor who pulls that data for the first time: Cobb only holds a couple of tax sales a year, and seven cities inside the county bill their own property taxes on a separate cycle the county list never sees.

This guide covers every free source of Cobb County tax delinquent data, what each one actually contains, the two blind spots that make the raw files misleading, and a practical workflow for turning scattered PDFs into a list you can work.

How Delinquency Works in Cobb County

Georgia runs a non-judicial tax sale system, and Cobb follows the standard statutory path. Understanding the timeline tells you which list a property should appear on and how much runway you have before it moves.

1. October 15 -- County property taxes are due. Anything unpaid after this date is considered delinquent and begins accruing interest and penalties.
2. 30-day late notices -- The Tax Commissioner's office mails late notices on all unpaid accounts after the October 15 deadline.
3. Tax execution (Fi.Fa.) -- If the account stays unpaid, the county issues a fieri facias, a tax execution that becomes a recorded lien against the property on the General Execution Docket at the Clerk of Superior Court.
4. Levy and advertisement -- The property is levied and advertised ahead of a scheduled tax sale.
5. Non-judicial tax sale -- The property is sold on the courthouse steps. The purchaser receives a tax deed immediately, subject to redemption.
6. 12-month redemption -- The owner (or any party with an interest) can redeem for 12 months after the sale.

The redemption price is the bid amount plus taxes paid after the sale, special assessments, sheriff and advertisement costs, plus a 20% premium for the first year or fraction of a year, and a 10% premium for each additional year. That 20% floor is why a redeemed Georgia tax deed is still a respectable outcome rather than a wasted year.

The Tax Commissioner's Two Free Lists

This is the primary free source, and it is genuinely good. The Cobb County Tax Commissioner publishes two separate lists, both updated monthly:

The Delinquent Tax List

A current list of accounts with unpaid taxes, available for viewing and refreshed monthly. This is the evergreen asset -- it is far larger than any tax sale list and it exists year-round, not just in the weeks before an auction. If you only take one file from Cobb, take this one.

One thing to know up front: the office notes that it cannot modify or reformat documents in response to requests, citing Georgia's open records statute. You get the file in the format the county produces it in. Nobody is going to hand you a clean CSV because you asked nicely -- the parsing work is yours.

The Excess Funds List

A monthly list of surplus proceeds from prior tax sales. Parcels that have been completely paid out are shaded on the listing, so you can visually separate live opportunities from closed ones. More on this below.

The Tax Sale List -- and the Timing Trap

Here is where Cobb differs from the metro Atlanta counties investors usually cut their teeth on. Georgia's framework contemplates sales on the first Tuesday of each month, and some counties do exactly that. Cobb does not run a sale every month. The 2026 calendar has two scheduled non-judicial tax sales: May 5 and November 3.

Sales are held at Superior Court Plaza, at Haynes Street and Washington Avenue, running from 10 a.m. to 4 p.m. The county also reserves the right to add or cancel sales according to its business needs, so the calendar is not a guarantee.

The practical consequence: tax sale lists only become available roughly four weeks before each scheduled sale. If you build your Cobb strategy around the sale list, you have two narrow windows a year and about 28 days of lead time in each to research, drive, skip trace, and make contact. That is not enough runway to do good work.

The counties where investors do well are the ones where they work the delinquent list continuously and treat the sale list as a deadline, not a discovery tool. In Cobb that distinction matters more than almost anywhere else in metro Atlanta.

If You Do Plan to Bid

• Pre-registration is mandatory for each sale, completed online before the sale date.
• Bidder cards are issued from 9:00 a.m. to 10:00 a.m. on the day of the sale, and valid photo ID is required.
• Payment in full is due at the conclusion of the sale, in cash or certified check. There is no financing window.
• The opening bid equals the tax due plus penalties and all applicable costs.

The Seven-City Blind Spot

This is the single most useful thing to know about Cobb data, and it is almost never mentioned in generic Georgia guides.

Seven municipalities inside Cobb County bill and collect their own city property taxes: Acworth, Austell, Kennesaw, Mableton, Marietta, Powder Springs, and Smyrna. A property inside one of those city limits is taxed by both the city and the county, and the owner receives two separate tax bills, from two separate offices, with different due dates and different millage rates.

What that means for your list:

Scenario	On the county delinquent list?	What you are missing
Delinquent to Cobb County only	Yes	Nothing -- this is the normal case
Delinquent to the city only	No	A genuinely distressed owner who is invisible in county data
Delinquent to both	Yes	The true severity -- county list understates total tax owed

Two takeaways. First, an owner who is behind on city taxes but current with the county never shows up in the file you downloaded -- and financial distress rarely stays confined to one bill for long, so these are early-signal leads. Second, for any property inside those city limits, the tax owed figure on the county list is not the total tax exposure. If you are underwriting off that number, you are underwriting off a fraction.

Checking seven separate city offices by hand is tedious, which is exactly why most investors skip it and why the leads sitting there stay uncontacted.

Excess Funds and the Interpleader Wrinkle

When a Cobb tax sale brings more than the taxes and costs owed, the surplus is excess funds -- and it legally belongs to the former owner and other interested parties in order of priority, not to the county.

Cobb's stated office policy is that excess funds, along with future excess funds, are interpled to the Cobb County Superior Court. That is a meaningful procedural detail. Once funds are interpled, the claim is resolved through a court action rather than an administrative request across the counter, which lengthens timelines and typically means competing claimants are sorted out by a judge.

Excess funds requests submitted to the office are answered within one to three business days, and the Levy office can be reached at (770) 528-8623 if a request goes unanswered past that window. Parcels already paid out in full are shaded on the published listing.

If surplus recovery is new to you, our guide to tax deed surplus funds covers how these claims work and where the real economics are. Georgia caps and rules differ from other states, and fee limits vary state to state -- never assume a flat national percentage applies.

Two More Free Offices Worth Joining

Cobb County Board of Tax Assessors

The assessor's site is your free source for property characteristics, assessed values, owner of record, and parcel data. The delinquent list tells you who owes; the assessor tells you what it is worth and what is actually there. A $4,000 tax bill means something very different on a vacant half-acre than on a 3,200-square-foot house.

Clerk of Superior Court -- Deeds and the General Execution Docket

The Clerk's office holds recorded deeds and the General Execution Docket where tax Fi.Fas. and other liens are recorded. Georgia's statewide clerks' search system consolidates deed and lien records across counties, which makes it possible to check a Cobb parcel's recorded chain and outstanding executions without a trip to Marietta. Cross-referencing here is how you catch the property that has a tax Fi.Fa. plus three other judgment liens -- a very different deal than the one with a clean docket.

What the Free Data Does Not Give You

Free county data is accurate and authoritative. It is also raw. Here is what it will not tell you:

• Whether the owner is alive. County records list the owner of record, not their status. Deceased-owner and heir-property situations are extremely common on long-delinquent parcels, and Georgia has not adopted the Uniform Partition of Heirs Property Act -- which makes heir situations here both more common and more consequential than in neighboring states.
• Where the owner actually is. The mailing address on a delinquent account is frequently the property itself, which is often exactly where the owner no longer lives.
• How to reach them. No phone numbers, no emails, no relatives.
• Cross-county or cross-city exposure. The seven-city problem above, plus owners holding delinquent parcels in multiple Georgia counties.
• Any prioritization. A 300-page PDF sorted by parcel number gives you no way to tell a 12-year delinquency with a dead owner from a first-year oversight on a well-maintained home.

The gap between "I downloaded the list" and "I have a working pipeline" is where almost everyone stalls. For the broader statewide picture, see our free Georgia tax delinquent property list guide, and for a county that does run monthly sales, compare the Gwinnett County guide.

A Practical Free-Data Workflow for Cobb

1. Pull the monthly delinquent list from the Tax Commissioner. This is your base file. Re-pull it monthly -- the refresh is the whole point.
2. Flag the city parcels. Separate properties inside Acworth, Austell, Kennesaw, Mableton, Marietta, Powder Springs, and Smyrna. Their county tax owed figure is incomplete by definition.
3. Join to assessor data for value, improvements, acreage, and owner of record. Kill anything where tax owed is not meaningfully below value.
4. Check the General Execution Docket on your shortlist for other recorded liens and executions before you invest research time.
5. Sort by years delinquent, not dollars. Duration is the strongest distress signal in tax data. A small balance carried eight years beats a large balance carried one.
6. Screen for deceased-owner and heir signals on the survivors. These are the deals with the least competition because they take the most work.
7. Skip trace the shortlist and start contact well before the four-week sale window, not during it.
8. Pull the excess funds list separately as its own opportunity stream, and note that Cobb interpleads to Superior Court.

Done by hand, steps 1 through 6 are a solid weekend of work every single month. That is the real cost of "free."

Frequently Asked Questions

Is the Cobb County delinquent tax list actually free?

Yes. Both the delinquent tax list and the excess funds list are published by the Tax Commissioner and updated monthly at no cost. The county will not reformat the files for you, so expect to do your own parsing.

How often does Cobb County hold tax sales?

Not monthly. The 2026 calendar has two scheduled non-judicial sales, May 5 and November 3, held at Superior Court Plaza. The county reserves the right to add or cancel sales, so confirm before planning around a date.

When does the Cobb tax sale list come out?

Roughly four weeks before each scheduled sale. This is why the year-round delinquent list is more useful than the sale list for anyone doing real owner outreach.

What happens if the owner redeems after I buy a tax deed?

You are repaid the bid amount, post-sale taxes, special assessments, and costs, plus a 20% premium for the first year or fraction of a year, and 10% for each additional year. Redemption runs 12 months from the sale.

Does the county list include city tax delinquencies?

No. Acworth, Austell, Kennesaw, Mableton, Marietta, Powder Springs, and Smyrna bill their own city property taxes separately. A property can be delinquent to a city while current with the county and never appear on the county list.
