Deep-dive analysis
Dekalb market analysis
DeKalb County sits at a gross rent-to-price ratio of 6.37% and a 4.14% cap rate, which tells you most of what you need to know before you run a single spreadsheet line. That places it squarely in appreciation-leaning territory, not the cash-flow end of the spectrum, but not deep appreciation country either. The cash-flow score of 64 sounds encouraging until you look at the actual investment estimate: at a $332,528 purchase price with 20% down and a 6.85% rate, the modeled monthly mortgage sits at $1,743. Add $618 in estimated expenses and you're carrying $2,361 in monthly costs against $1,764 in median rent, producing a negative $597 monthly cash flow and a cash-on-cash return of -9.37%. Median home prices are also down 1.82% year-over-year, so you are not being compensated on the appreciation side to offset the carry loss. The affordability index of 59 and the overall score of 54, ranking 528th out of 1,000 counties nationally and 85th out of 159 in Georgia, confirm that this is a middle-of-the-road market with a real negative carry problem at current financing costs.
The investor this market suits is not a traditional cash-flow buyer running conventional financing at 6.85%. The numbers don't support that thesis at the median price point. The more realistic buyer here is either a value-add operator who can force appreciation or rental upside well above the $1,764 median, or an investor paying meaningfully below median to shift the rent-to-price ratio into workable territory. At a purchase price closer to $270,000 to $280,000, the math starts to breathe, though break-even rather than positive cash flow remains the realistic base case. A pure appreciation buyer would need conviction that DeKalb's price trend reverses, which the -1.82% YoY data does not currently support. The 761,209 population does give the market depth and liquidity that smaller counties cannot offer, meaning exit options are real, but that is a consolation for the trader, not a fix for the landlord running negative monthly.
The combined monthly tax and insurance burden runs $355 on the median-priced asset, which is material but not punishing. The state-average effective property tax rate used here is 0.92%, flagged as "normal," which means it is not the headline risk in your underwrite the way a 1.7%-plus rate would be in some Midwest markets. Annual property tax on the median asset is estimated at $3,059 and annual insurance at $1,197, for a combined $4,256 per year. That figure is already baked into the $618 estimated expense figure, so there is no hidden multiplier here, but it's worth noting as a state-average estimate only. The honest caveat is that Georgia county and municipal millage rates vary considerably, and DeKalb's actual rate may differ from the 0.92% state average in either direction. Pull the actual millage rate for the specific township before you close.
On the risk side, the data most directly flags a concentration concern: this is a large, single metro-adjacent county where rental demand is tightly linked to the broader Atlanta labor market. No specific economic anchors or employer data were provided, so no employer-level commentary is warranted, but the implication of a 761,000-person urban county adjacent to Atlanta is that demand is real but so is competition from institutional landlords and a continuously expanding apartment supply base. The -1.82% YoY price movement suggests that softening is already underway at current interest rate levels, which matters both for entry price negotiation and for assumptions about terminal cap rate when you exit.
Compared to the neighboring counties in the data, DeKalb's competitive position is mixed. Rockdale County to the southeast is the clearest alternative worth modeling: median home price of $299,702, nearly identical median rent at $1,760, but a rent-to-price ratio of 7.05% versus DeKalb's 6.37%. That 68-basis-point difference in gross yield is meaningful at scale and, all else equal, Rockdale gets you closer to break-even on a conventional 20% down loan with fewer dollars at risk. Walton County shows a higher median rent of $1,929 but a lower rent-to-price ratio of 6.05% on a $382,605 median price, making it a worse cash-flow proposition than DeKalb despite the higher nominal rent. Heard County's $267,133 median is the lowest in the comparison set, which could open up better entry yields if rents are even partially supportable, but rent data wasn't provided so no ratio can be calculated. Morgan and Pickens Counties carry higher prices, $451,534 and $382,716 respectively, without accompanying rent data, so they cannot be evaluated on yield terms. The case for choosing DeKalb over Rockdale comes down to liquidity and depth: DeKalb's 761,000-person population dwarfs Rockdale's, and if portfolio size, tenant pool access, or future resale velocity matter to your strategy, DeKalb wins on those dimensions. If your primary constraint is making the monthly cash flow work at current rates, Rockdale's 7.05% gross yield is the better starting point.

The Bottom Line
Dekalb County in Georgia scores 54/100, ranking #528 of 1,000 US counties (top 67%). At 20% down and current rates, a median-priced rental loses about $597/month; the 6.37% gross rent-to-price ratio doesn't survive debt service. The thesis here is appreciation, value-add, house hacking, or all-cash.
