Quick table you can screenshot

Prices and affordability: what changed from last year

Prices moved up again, but not in a way that removes negotiation entirely.

• The median sold price was $463,750 in December, up 4.21% year over year.

• The average sold price was $554,750, up 3.86% year over year.

Why do median and average both matter? The median is often the best “typical” price point. The average can swing more when higher-priced homes close in pockets like Vinings, East Cobb, and parts of the Cumberland area near Truist Park.

The list-to-sold price ratio landed at 97.8%, slightly lower than last year. That is a small shift, but it is meaningful. It suggests buyers are negotiating a bit more than they did last December.

What this means if you are selling

If you list a home that is priced correctly and looks move-in ready, you can still expect strong activity. If you list above the best comparable sales, you may get showings but fewer clean offers. In this market, pricing is not a “set it and forget it” decision. It is the start of your marketing plan.

What this means if you are buying

Rising year-over-year prices do not eliminate opportunity. They change how you win. The best approach is to focus on home condition, days on market, and terms. In many situations, buyers are finding value through credits, repairs, and closing timing, not just a lower price.

Listings and sales: supply vs demand in plain English

New listings rose to 528 in December, up 10.69% from last year. More inventory is usually good news for buyers, especially in popular corridors like:

• Marietta near Marietta Square

• Smyrna near The Battery Atlanta

• Kennesaw near Kennesaw Mountain

• Mableton near access points to the Silver Comet Trail

• Acworth with quick access to I-75 and Lake Allatoona areas

At the same time, sold listings fell to 520, down 9.57% year over year.

That combination often points to a market where buyers have more choices, but they are making decisions carefully. Some are waiting for the right fit. Others are being selective on condition and total monthly payment. Either way, it puts more emphasis on preparation and positioning.

If you are selling, this is where small details matter. Clean photos, a strong first-week plan, and a realistic list price tend to separate the listings that move from the ones that sit.

If you are buying, a higher pace of new listings can create better selection windows. That matters if you are trying to stay close to major hubs like Cumberland, Downtown Marietta, or the Smyrna and Vinings areas that connect quickly into Atlanta.

Days on market and negotiation: how deals are getting done

Median days on market stayed at 32 days in December. Average days on market stayed at 46 days. That stability tells a story.

Homes are still moving on a predictable timeline when they are priced well and presented clearly. At the same time, negotiation is showing up more often in the details of the contract.

Here is the year-to-date context for 2025:

• YTD median days on market: 22 (up from 16 last year)

• YTD average days on market: 39 (up from 32 last year)

That suggests 2025 required more patience than 2024 overall, even as prices edged higher. It also hints that buyers had more time to compare options in many price bands.

Practical negotiation notes

• Sellers: Expect more inspection focus and more requests for credits unless the home is turnkey.

• Buyers: Ask for what matters, but stay realistic on the best listings. Homes that show well and are priced right can still attract multiple offers.

Neighborhood context across Cobb County

Countywide numbers are a helpful baseline, but your results depend on the micro-market. Cobb County has a wide mix of home styles, lot sizes, HOAs, and commute patterns. That is why the same “median” can feel very different from one area to another.

A few examples of what tends to drive differences:

• Vinings and river-adjacent areas: higher price bands and more month-to-month variation.

• East Cobb: wide spreads based on updates, floor plan, and subdivision demand.

• Smyrna: strong demand near The Battery Atlanta, with a mix of townhomes and older renovated homes.

• Marietta: diverse inventory from near the Square to newer builds farther out.

• Kennesaw and Acworth: a range of resale options, with demand shaped by access to I-75 and local parks.

A real scenario we see often

A homeowner in West Cobb lists slightly above the most recent closed comps because they have upgrades. The listing gets traffic, but offers come in under list and include credit requests. After a targeted price adjustment and a stronger weekend showing plan, the seller lands a cleaner offer with fewer concessions.

The lesson is simple. Upgrades help, but buyers still anchor to comparable sales and total monthly payment.

Next steps for buyers, sellers, and investors

If you are buying

1. Pick 2 to 3 target areas, then track days on market for your price band for two weeks.

2. Use your offer terms strategically. Closing flexibility can matter as much as price.

3. Focus inspections on major systems first. Roof, HVAC, plumbing, electrical, and foundation items carry the most risk.

If you are selling

1. Price to your competition, not the highest sale you saw online.

2. Plan your first 7 days like a launch. Photos, showings, and clean disclosures matter.

3. Consider pre-list improvements that reduce buyer objections, especially paint, lighting, and minor repairs.

If you are investing

1. Track negotiation room. A small shift in list-to-sold can change returns.

2. Evaluate HOA rules early when townhomes or condos are involved.

3. Build your exit plan before you buy. Know your likely resale buyer and your holding timeline.
