Cobb County, Georgia Tax Sale Investing Guide
Cobb County holds monthly redeemable tax deed auctions on the first Tuesday of each month at the county courthouse in Marietta. Georgia's unique system gives winning investors an actual deed — not a lien certificate — subject to the former owner's 12-month right to redeem by paying the purchase price plus a 20% penalty.
Cobb County tax sales are held on the first Tuesday of each month at 70 Haynes Street at Flournoy Park, Marietta GA 30090. Properties are advertised in Marietta Daily Journal for four consecutive weeks. The winning bidder pays the county and receives a redeemable deed. The former owner has 12 months to redeem by paying the investor back plus a 20% penalty. If unredeemed after 12 months, the investor can begin barment to permanently extinguish the redemption right and pursue marketable title through quiet title action.
Cobb County Market Overview
Cobb County is a major Georgia county with a consistently active tax sale program. Georgia's redeemable deed system is a hybrid between tax lien and tax deed states — investors receive immediate deed ownership at auction, but the former owner retains a statutory right to reclaim the property for 12 months. This structure creates two potential outcomes: a 20% flat return if the owner redeems, or full property ownership if they do not.
Cobb County is a consistently strong suburban market with among the highest residential property values in the Atlanta metro area. Communities like East Cobb, Vinings, and Smyrna have well-established values and strong redemption rates. The Cobb County Tax Commissioner publishes a Real Property Tax Sales booklet with detailed investor guidance — one of the most helpful county-level investor resources in Georgia. After the 12-month redemption period, barment notices for Cobb properties follow the standard O.C.G.A. § 48-4-45 process. Code violations in Marietta, Smyrna, and Kennesaw are tracked by each city separately from county records.

The Auction Process in Cobb County
Cobb County Tax Sales are held on the first Tuesday of each month on the steps of the Superior Courthouse at Flournoy Park in Marietta, between 10 AM and 4 PM. The Cobb County Tax Commissioner's office at cobbtax.gov is an excellent resource — they publish a Real Property Tax Sales booklet that explains the sale process, investor rights, and post-sale procedures in detail. Obtain this before attending your first Cobb auction. The sale list is advertised in the Marietta Daily Journal for four consecutive weeks.
Before the auction, the county must publish the sale notice in Marietta Daily Journal for four consecutive weeks. This publication is your signal that a sale is upcoming — monitor the legal notices section to identify sale dates and the properties being offered. The advertisement includes the owner's name, property description, and the amount of tax due.
The 20% Penalty: Your Return on Investment
Georgia's 20% penalty is a flat return — not an annualized rate. Under O.C.G.A. § 48-4-2, the redeeming owner must pay: the full auction purchase price, plus any subsequent taxes the investor paid on the property, plus a 20% penalty on the aggregate total. Here is what that looks like on a typical property:
Year 1 Redemption Example
After Year 1, an additional 10% penalty per year accrues until barment is completed. This escalating structure incentivizes early redemption and rewards investors who hold longer if the owner delays.
Restrictions During the 12-Month Redemption Period
Even with a deed in hand, Georgia law imposes significant restrictions during the redemption period. You cannot take physical possession, evict occupants, demolish structures, or make improvements. The deed functions as a lien equivalent until barment is complete. Violating these restrictions can create legal liability and jeopardize your ownership position.
Barment and Quiet Title in Cobb County
After 12 months from the sale date, you may begin the barment process under O.C.G.A. § 48-4-45. This requires: (1) a title search to identify all parties with recorded interests, (2) certified mail notice to the former owner, occupants, and all lienholders, (3) publication in Marietta Daily Journal for four consecutive weeks, and (4) a 30-day waiting period after notice. Record the completed barment in county records.
Following successful barment, a quiet title action through Georgia Superior Court is typically required before a title insurance company will insure the property. This is necessary for conventional financing or resale. The full process from auction to marketable title on a non-redeemed property typically takes 18–24 months minimum. Plan your capital accordingly.

Frequently Asked Questions — Cobb County
Cobb County tax sales are held on the first Tuesday of each month at 70 Haynes Street at Flournoy Park, Marietta GA 30090, 10 AM–4 PM. Not every month has a sale — check the legal notices in Marietta Daily Journal and the county's official resources to confirm upcoming dates. The property list is advertised for four consecutive weeks before each sale.
In Florida (a tax lien state), you buy a certificate representing the right to collect a debt — you earn interest while the owner retains the property. In Georgia (a redeemable deed state), you buy an actual deed to the property. The former owner has 12 months to buy it back by paying you plus a 20% penalty. If they don't, you pursue full ownership through barment and quiet title. Georgia's system is faster to potential ownership but requires more capital at auction and more legal work to obtain marketable title.
If the owner redeems, the process ends at redemption — you collect your 20% and the deed is cancelled. If the owner does not redeem, the minimum timeline is: 12 months (redemption period) + 2–3 months (barment process) + 3–6 months (quiet title action) = approximately 17–21 months from auction to marketable title. Always consult a Georgia real estate attorney and account for this timeline in your investment planning.
