Renting vs. Buying in Marietta, GA: The Real 2026 Math
Is It Cheaper to Rent or Buy in Marietta, GA Right Now?
At today's rates, buying a median-priced home in Marietta or Kennesaw with 20% down runs close to what you'd pay to rent a comparable single-family house in Cobb County, roughly $2,300 to $2,760 a month depending on your down payment. Renting a smaller apartment is cheaper month to month, but it isn't the same product as the house you'd be buying. The price-to-rent ratio in this market, generally 11 to 17 depending on the comparable used, sits well below the range where renting is the clear financial winner, which is the opposite of what the math often looks like in coastal California, New York, or South Florida.
TL;DR
- A $364,000 home in Kennesaw with 20% down and a 6.69% rate runs about $2,320 a month in principal, interest, taxes, and insurance, with no PMI.
- The same home with 10% down runs closer to $2,760 a month once PMI is added, since the loan balance and PMI premium both grow.
- Renting a comparable 3-bedroom house in Cobb County typically runs $1,760 to $2,850 a month, which puts owning and renting in the same range for a house-to-house comparison.
- Cobb County's price-to-rent ratio lands roughly between 11 and 17, a zone that generally favors buying, unlike the 20-plus ratios common in expensive coastal markets many relocation buyers are moving from.
- Renting still wins if you're staying under two years, aren't sure where you're landing yet, or don't have the cash for a down payment plus Georgia's closing costs.
Every week I talk with buyers relocating from California, New York, or Florida who assume renting for a year or two in Marietta is the obvious safe move while they get their bearings. It's not an unreasonable instinct. In a lot of the markets they're leaving, it's the correct one. But the numbers here don't tell the same story, and the gap between what people assume and what's actually true is exactly where I see relocation buyers leave money on the table.
The Real Cost of Renting vs. Buying in Marietta Right Now
Let's use a real number instead of a national average. The median sale price in Kennesaw is $364,000 (Redfin, three months ending June 2026), and it's a reasonable stand-in for Cobb County's broader market. The current 30-year fixed rate is 6.69% as of September 1, 2026, based on national rate tracking.
The 20% Down Payment Scenario
Put down 20% ($72,800) on a $364,000 home and you're financing $291,200. At 6.69%, that's:
- Principal and interest: about $1,877 a month
- Property taxes: about $303 a month, based on Cobb County's roughly 1.00% effective rate
- Homeowners insurance: roughly $140 a month
- PMI: none, because you're at 20% equity
- Estimated total (PITI): about $2,320 a month
The 10% Down Payment Scenario: What PMI Adds
Most relocation buyers don't walk in with 20% down sitting in a checking account, so let's be honest about the version most people actually run. Put down 10% ($36,400) and you're financing $327,600:
- Principal and interest: about $2,112 a month
- Property taxes and insurance: the same $303 and $140
- PMI: roughly $205 a month at a typical rate for this loan-to-value
- Estimated total (PITI): about $2,760 a month
Now compare that to renting. A three-bedroom apartment in Marietta averages about $1,648 a month (average-rent.com, 2026 data). But an apartment isn't what most relocation buyers are actually comparing themselves to. A three-bedroom single-family rental house in Cobb County typically runs $1,760 to $2,850 a month, with most listings clustering between $1,760 and $2,500 (RentCafe, 2026 data).
Line those up against the ownership numbers above and the gap mostly disappears. Renting a comparable house and buying one with 20% down land in almost the same monthly range. The apartment is genuinely cheaper, but it's also a different kind of housing, usually smaller, with different rules about pets, upgrades, and lease renewals.
Why the California and New York Math Doesn't Travel to Cobb County
This is the part of the conversation I have most often with buyers relocating from expensive markets, and it's where my background as a certified residential appraiser actually matters here, not just as a credential but as a way of thinking about value.
Appraisers and analysts use something called a price-to-rent ratio: take the home's price and divide it by what a year of rent would cost you for a comparable property. As a rough rule of thumb, a ratio under 15 tends to favor buying, 15 to 20 is closer to a toss-up, and north of 20 usually tips toward renting.
Run that math for Cobb County using the $364,000 median price:
- Against the low end of comparable house rent ($1,760/month, $21,120/year): ratio of about 17
- Against the midpoint of comparable house rent (roughly $2,300/month, $27,600/year): ratio of about 13
- Against the high end of comparable house rent ($2,850/month, $34,200/year): ratio of about 11
That range, roughly 11 to 17, sits in territory that generally favors buying, or at worst calls it close. In a lot of the coastal California, New York, and South Florida markets I hear about from relocation clients, price-to-rent ratios commonly run well north of 20, sometimes into the 25 to 35 range, which is exactly the zone where renting and investing the difference genuinely can outperform buying. That's the instinct relocation buyers are bringing with them. It's a correct instinct for the market they're leaving. It's not automatically correct here.
Closing costs are part of this math too, and they're not trivial. Between the loan estimate line items, attorney fees, and prepaids, buyers in Cobb County typically pay somewhere in the range covered in my breakdown of buyer closing costs. That upfront cost is the real reason the rent-versus-buy math only pays off if you're planning to stay long enough to amortize it, generally somewhere past the two to three year mark.
When Renting Still Makes More Sense in Cobb County
I'm not going to tell every relocation client to buy immediately, because that's not honest advice, and it's not what I'd tell a friend.
Renting still makes more sense if:
- You're staying under two years. Closing costs and the transaction cost of selling again eat most of the benefit of a short hold.
- You don't know where you're landing yet. If you're not sure whether you want Kennesaw, Marietta, or Acworth, renting for six months to a year while you learn the area is a completely reasonable move, and one I recommend to plenty of relocation clients.
- You don't have the down payment and closing cost cash together yet. Buying with nothing saved and stretching every dollar to close is a common way relocation buyers end up house-poor.
- Your job situation in Atlanta isn't settled. If there's a real chance you're transferred again within a year or two, renting removes that risk entirely.
If you already own a home elsewhere and you're weighing whether to buy here before you sell there, that's a related but different question, and I've walked through the financing and timing tradeoffs in my guide to buying before you sell in Cobb County.
Your specific number is going to depend on your down payment, your timeline, and what you're actually comparing the purchase to, which is exactly why this is a conversation, not a spreadsheet formula. That's the kind of question I walk relocation clients through before we ever tour a house.
Frequently Asked Questions
Is it cheaper to rent or buy in Marietta, GA in 2026?
It depends on what you're comparing. Renting a small apartment is cheaper month to month than owning, but renting a comparable single-family house runs close to the same monthly cost as buying one with 20% down at today's 6.69% rate. For Marietta and the surrounding Cobb County market, the house-to-house comparison is closer than most relocation buyers expect.
What is a price-to-rent ratio and how does it apply in Cobb County?
A price-to-rent ratio divides a home's price by a year's worth of comparable rent. A ratio under 15 generally favors buying, 15 to 20 is closer to neutral, and above 20 usually favors renting. Cobb County's ratio currently runs roughly 11 to 17 depending on the rental comparable used, which is meaningfully lower than the 25-plus ratios common in many expensive coastal markets.
How much down payment do I need to buy a house in Cobb County?
A 20% down payment on Kennesaw's roughly $364,000 median price is about $72,800, which avoids PMI entirely. Conventional loans allow as little as 3% to 5% down, and FHA loans allow 3.5%, though both options add monthly mortgage insurance until you build enough equity. You can see how these numbers layer with attorney fees and prepaids in my buyer closing costs breakdown.
Does renting make more sense if I'm not sure how long I'll stay in Georgia?
Generally, yes. Closing costs and the cost of selling again mean buying usually needs a holding period of at least two to three years to make financial sense. If you're not confident you'll stay that long, renting while you confirm the job and the area, whether that's Kennesaw, Acworth, or somewhere else in Cobb County, is often the smarter short-term move.
Can I buy a home in Marietta with no down payment?
Yes, if you qualify for a VA loan. Eligible veterans and active-duty service members can buy with 0% down, which changes the rent-versus-buy math significantly since there's no down payment to save toward. I cover the specifics, including the funding fee and property requirements, in my guide to VA loans for buyers in Marietta.
Whether you're weighing renting for another year or buying now, the honest answer depends on your timeline, your down payment, and what you're actually comparing your rent to. Relocating from California, New York, or Florida makes this decision harder, not easier, because the market you're used to and the market you're moving into don't run on the same math.
