For households debating whether to rent or buy around North Atlanta, the monthly math has become increasingly difficult to ignore.

A new Zillow analysis found that across metro Atlanta, the typical renter pays about $1,853 a month, while the typical new homebuyer faces a monthly payment of about $3,122 including mortgage, property taxes and insurance. That is a difference of $1,269 a month, or $15,228 over a year.

Move north from Atlanta, however, and the calculation changes. Rents are not necessarily dramatically higher in the suburbs, but home values often are.

In Alpharetta, Zillow puts the typical home value at about $716,600 while its rental index is about $2,137 a month. Johns Creek has a typical home value of roughly $695,000 and rent of about $2,548. Roswell stands at approximately $653,100 for a typical home and $1,724 for rent.

The pattern continues farther north and east. Cumming’s typical home value is about $595,100, with rent around $2,253. Suwanee is almost identical on the ownership side at roughly $594,700, while rent averages about $1,915. Duluth, where home values are considerably lower, sits at approximately $437,800 with rent around $1,658.

Sugar Hill’s typical home value is about $440,400 and its rental index is $1,968. Peachtree Corners presents one of the more striking contrasts: a typical home value near $542,900 while Zillow’s rental measure is about $1,487.

What today’s mortgage rate does to the calculation

The financing side makes those suburban home prices more significant. Freddie Mac reported an average 30-year fixed mortgage rate of 6.95% as of Sept. 17.

Using that rate, a 20% down payment and Zillow’s typical home value as a simple benchmark, North Atlanta Star estimates that principal and interest alone would run about $3,795 a month in Alpharetta and $3,681 in Johns Creek. In Cumming and Suwanee, it would be roughly $3,150 a month. Duluth comes in around $2,318 and Sugar Hill around $2,332.

Those figures do not include property taxes, homeowners insurance, HOA fees, maintenance or closing costs, meaning the actual cost of ownership would be higher.

For comparison, using the same calculation on Atlanta city’s typical home value of about $381,900 produces principal and interest of roughly $2,023 a month. Zillow’s city rental index is about $1,944.

That helps explain an important distinction hidden inside the broader Atlanta numbers. Renting in North Atlanta can cost as much as, or sometimes more than, renting in the city. But buying a typical home in many northern suburbs requires financing a property worth hundreds of thousands of dollars more.

The suburbs are not one housing market

There are substantial differences even within North Atlanta. Alpharetta and Johns Creek combine relatively high rents with home values approaching $700,000. Cumming and Suwanee remain expensive to buy even though rents are closer to the metro norm. Duluth and Sugar Hill provide a noticeably lower entry point for buyers, while Peachtree Corners has an unusually large spread between Zillow’s rental measure and typical home value.

There is an important limitation to the comparison. Zillow’s rental index represents the rental market, which includes many apartments, townhomes and smaller properties. Its home-value index covers the broader ownership market. A family comparing the same four-bedroom house for rent and for sale may see a very different gap.

The numbers nevertheless capture the broader choice facing many North Atlanta households this fall. Buying can still provide equity, stability and protection from future rent increases. Renting provides flexibility and, in today’s market, can leave considerably more money available each month.

With mortgage rates again close to 7% and typical home values around $600,000 to $700,000 in several of North Atlanta’s most sought-after communities, the old assumption that renting is simply money thrown away has become a much more complicated argument.

Put against local incomes, renting has the easier monthly math

The difference becomes sharper when housing costs are compared with what local households actually earn. Median household income, rather than an individual salary, is the more useful measure because many North Atlanta homes depend on two earners. The latest Census figures put median household income at about $160,100 in Johns Creek, $147,600 in Alpharetta and $143,800 across Forsyth County. It falls to roughly $107,400 in Sugar Hill, $103,300 in Suwanee and $95,300 in Duluth. Atlanta city is about $85,700.

Using the rent and home-price figures above, the typical rent consumes only about 17% of median household income in Alpharetta, 19% in Johns Creek and South Forsyth, 21% in Duluth and roughly 22% in Suwanee and Sugar Hill. Atlanta is different: typical rent takes about 27% of the city’s median household income.

Buying changes the picture quickly. At the mortgage rate used in our calculation, principal and interest alone equal about 31% of median household income in Alpharetta, 28% in Johns Creek, 26% in South Forsyth, 37% in Suwanee, 29% in Duluth and 26% in Sugar Hill. Those numbers are before property taxes, homeowners insurance, HOA fees and maintenance. HUD generally considers a household housing-cost burdened when total housing expenses exceed 30% of gross income.

Another way to see it is through salary. A household earning $100,000 a year has about $8,333 in gross monthly income, putting the 30% housing line at roughly $2,500. That is enough to cover the typical rent in all of the communities in this comparison. It is not enough to cover the estimated mortgage principal and interest on a typical home in Alpharetta, Johns Creek, South Forsyth or Suwanee, even before taxes and insurance are added.

At $150,000 in annual household income, the 30% line rises to $3,750 a month. Buying becomes much more plausible in Duluth, Sugar Hill and parts of South Forsyth, but the full cost of owning a typical Alpharetta or Johns Creek home can still push beyond that level once taxes, insurance and other expenses are included.

For households deciding strictly on today’s monthly cash flow, renting therefore has the advantage across most of North Atlanta. The region’s higher salaries help, but they have not completely caught up with home prices and borrowing costs. Buying becomes more financially competitive for households bringing a large down payment, earning well above the local median or planning to remain in the home long enough for equity and future appreciation to outweigh the higher near-term cost.
