Know before you go
- Median home values in the Census Bureau’s 2020-2024 figures run from about $335,000 in Kennesaw to about $701,000 in Decatur.
- The county and school system an address sits in decide most of the property tax bill.
- Mean commute times sit between about 25 and 33 minutes across the places compared here.
Key takeaways
- There is no single answer to where to live in metro Atlanta; the right place depends on budget, commute and whether you rent or buy.
- Census Bureau figures show large gaps between places only a few miles apart, in home values more than in rents.
- The county, the city and the school district of an address set the tax rate, so check all three before you choose.
People moving to Atlanta often ask for the best part of town, as if one neighborhood suited everyone. A more useful question is which places fit your budget, your commute and the way you want to live. The metro is large: the Census Bureau estimates 529,110 people in the City of Atlanta alone in July 2025, and more than a million each in Fulton and Gwinnett counties. This guide compares a set of cities and counties using official numbers, so you can narrow the list before you start touring.
The numbers side by side
The table uses the Census Bureau’s QuickFacts, which draw on the American Community Survey for 2020-2024. These are medians across many homes and many years, so treat them as a sense of scale rather than today’s asking prices.
| Place | Median home value | Median gross rent | Mean commute (min) |
|---|---|---|---|
| Atlanta (city) | $439,600 | $1,711 | 26.5 |
| Decatur | $701,400 | $1,655 | 25.9 |
| Brookhaven | $692,700 | $1,882 | 25.1 |
| Alpharetta | $649,000 | $1,948 | 26.3 |
| Sandy Springs | $619,800 | $1,870 | 25.8 |
| Marietta | $448,500 | $1,586 | 27.5 |
| Cobb County | $407,200 | $1,730 | 29.4 |
| Gwinnett County | $380,900 | $1,810 | 32.8 |
| DeKalb County | $357,800 | $1,692 | 30.4 |
| Kennesaw | $335,400 | $1,845 | 28.6 |
Two things stand out. Home values swing far more than rents: the median value in Decatur is roughly double the one in Kennesaw, while the median rents differ by less than $200. And the places with the highest home values are not always the ones with the longest drive; Decatur, Brookhaven and Sandy Springs all show mean commutes near 26 minutes.
Start with the commute you will actually make
Write down where you will go most weekdays, then test the trip at the hour you would make it. Mean travel time is a county-wide or city-wide figure and hides big differences between streets. If rail matters to you, MARTA lists an average trip time from each of its 38 stations to the airport; North Springs, the last stop on the Red Line, shows 43 minutes, and Five Points downtown shows 16. Living near a station can change daily life more than living in a particular ZIP code. Our guide to MARTA and Commuting in Atlanta: Lines, Fares, Parking and Commute Times covers fares and parking.
County lines and school lines matter more than names
Many addresses carry a city name in the mailing address but sit in unincorporated county land, and the City of Atlanta itself crosses into DeKalb County. What decides the tax bill and the public schools is the county, whether the address is inside a city, and which school system serves it. Several cities run their own school systems, among them Atlanta, Decatur and Marietta. Elsewhere, the county school district usually serves the address. The details are in Atlanta-Area School Districts Explained: County Systems, City Systems and Your Tax Bill.
How much the tax rate changes
Georgia taxes homes on 40 percent of fair market value, and each mill is $1 per $1,000 of that assessed value. Using the 2026 rate sheets from the county tax commissioners, a $400,000 home before any exemptions would owe roughly $4,821 in unincorporated Cobb (30.13 mills), $5,578 in unincorporated Gwinnett (34.86 mills) and $7,054 in unincorporated DeKalb (44.090 mills). Homestead exemptions lower those numbers for owners who live in the home, but the gap between counties remains. See Atlanta-Area Property Taxes by County: 2026 Rates for DeKalb, Cobb, Gwinnett and Fulton for the full breakdown.
Renters and buyers read the map differently
If you rent, the narrow spread in median rents means you can try a part of the metro without paying much of a premium, and move later once you know the area. If you buy, the spread in values is where most of the money is, and the tax rate follows you every year.

Tip: Before you sign anything, look the address up on the county property records site. It shows the tax district, which tells you the county, city and school system in one line.
A short way to narrow the list
- Set a monthly budget first, including taxes and insurance if you buy.
- Draw a commute circle around work and test the drive or train ride at rush hour.
- Check the county, city and school district for each address you like.
- Compare the 2026 millage rate for that tax district.
- Visit on a weekday evening and a weekend, when traffic and noise differ.
Other things worth checking
The Census figures also show how settled each place is. In Johns Creek, 80.4 percent of homes are owner-occupied; in the City of Atlanta it is 46.4 percent, so a larger share of the city is rental housing. Households are smaller in the city, with 2.00 people per household against 2.98 in Gwinnett County. Neither is better; they describe different kinds of places, and they hint at what your street might feel like.
Growth is uneven too. Kennesaw’s population estimate rose 14.3 percent between April 2020 and July 2025, while Sandy Springs and Johns Creek show small declines over the same period. A fast-growing suburb can mean new homes and new traffic at the same time.
