Cost of Living in Kennesaw, GA: A Real 2026 Monthly Budget
What does it actually cost to live in Kennesaw, Georgia? Online cost-of-living calculators give you vague numbers. They don't tell you what a family of five pays for power in a hot Georgia summer, what homes really cost by ZIP code, or why out-of-state buyers get surprised by car tags, speeding fines, and property tax bills after they move.
I've lived in Cobb County since 1993 and help families relocate here every year. Below are the real numbers for housing, taxes, utilities, transportation, and food in Kennesaw, including figures from my own household.
The short answer
For a family buying a $450,000 home in Kennesaw, expect a baseline housing cost of about $4,250 a month (mortgage, taxes, insurance, utilities, trash, and HOA) before groceries, gas, or entertainment.
Housing costs by ZIP code
Housing is the biggest monthly expense. The median home price in Kennesaw sits around $420,000 to $450,000 depending on the time of year, but it changes a lot by ZIP code:
- 30152 (West Cobb side): about $400,000 is the entry point for a single-family home. Most updated homes run $450,000 to $650,000+.
- 30144 (east side, near KSU and historic downtown): you can still find options in the high $300s to low $400s.
Mortgage: on a $450,000 home with 10% down, principal and interest runs about $2,700 to $2,900 a month, depending on your rate.
Renting first? Expect about $1,800 to $2,200 a month for a standard two-bedroom apartment or townhome.
HOA fees: most swim and tennis neighborhoods run $500 to $900 a year. Townhomes often run $150 to $300 a month, which usually covers exterior maintenance.
Property taxes (and the senior exemption trap)
Cobb County's effective property tax rate is around 1%. On a $450,000 home, that's about $4,500 a year, or $375 a month. File for the homestead exemption once you move in to lower it.
Here's the detail that trips up out-of-state buyers every single year: the senior exemption trap.
In Cobb County, homeowners 62 and older get a 100% exemption from the school portion of their property tax bill. That cuts their bill dramatically. Buyers look at Zillow, see the seller paid $1,800 a year in taxes, and assume theirs will be the same. But if you're under 62, that exemption goes away when you buy, and your taxes jump to the full rate.
Always budget taxes based on your own situation, not the previous owner's tax bill. I run this number for every client before they make an offer.
Real utility bills for a family of five
Online calculators always undercount utilities. Here's what a family of five in a typical Kennesaw home really pays:
| Utility | Typical monthly cost |
|---|---|
| Power (Cobb EMC or Georgia Power), peak summer | $250 to $300 |
| Natural gas (yearly average on a budget rate) | $100 to $120 |
| Water and sewer | $150 to $200 |
| Trash (private hauler, about $100 per quarter) | about $33 |
| Fiber internet + 4 cell lines | about $300 |
| Total | about $800 to $950 |
A few notes: summers are hot and humid, so your A/C runs a lot. Gas runs higher if you heat with gas or have a heated pool, like I do. Water adds up if you irrigate a lawn or fill a pool. Trash pickup in Kennesaw is handled by private companies like Waste Pro and Republic, so you'll set that up yourself.
Transportation and two costs that surprise newcomers
Kennesaw isn't a walkable city. Unless you live right downtown, you'll drive everywhere. A short Uber ride across town runs about $20 to $25. Gas prices in Georgia are usually below the national average.
Georgia's TAVT (title tax) on your cars
Georgia doesn't charge a yearly car tax. Instead, when you move here and register a car from out of state, you pay a one-time Title Ad Valorem Tax (TAVT) of 3% of the vehicle's value. Bring two cars worth $50,000 combined and expect to pay about $1,500 at the tag office.
Georgia's Super Speeder law
People drive fast on I-75, but Georgia State Patrol and Cobb County officers don't mess around. Under Georgia's Super Speeder law, if you're caught going 85 mph or faster (or 75 mph or faster on a two-lane road), the state adds an extra $200 fine on top of your regular ticket. Don't pay it within 120 days and your license gets suspended.
Local tip: to avoid Barrett Parkway traffic, learn the back roads off the Big Shanty Connector. Once you know them, you can skip most of the retail traffic.
Food, groceries, and taxes at the register
Take a family of five to a sit-down restaurant around Kennesaw and you're not walking out for less than $100. Fast food adds up fast, too. That's why a lot of locals, including me, cook at home more. I love grilling my own steaks and burgers. Kennesaw has great grocery options, from Publix and Kroger to local markets.
Georgia has a flat state income tax of about 5%, and sales tax in Kennesaw is 6% (4% state plus 2% Cobb County), lower than some surrounding counties.
A full monthly budget for a $450,000 home
| Expense | Monthly |
|---|---|
| Mortgage (principal and interest, 10% down) | ~$2,800 |
| Property taxes | ~$375 |
| Home insurance | ~$125 |
| Utilities and connectivity | ~$850 |
| Trash and HOA | ~$100 |
| Baseline housing cost | ~$4,250 |
That's before groceries, gas, and entertainment. Even with home prices up, lower property taxes, below-average gas prices, and a 6% sales tax keep Kennesaw very competitive with other major metro areas.
