Johnston County

Johnston County sits at a gross rent-to-price ratio of 6.19%, which lands it squarely in the middle of the cash-flow-versus-appreciation spectrum, leaning slightly toward the cash-flow side without delivering on either end particularly well. The 4.02% cap rate is the clearest summary of where this market stands: better than many appreciation-driven metros but not the 6-7% territory where cash flow becomes reliably positive. Run the standard 20% down underwrite at a 6.85% rate and the picture sharpens quickly: a $339,986 purchase generates a $1,782 monthly mortgage, $614 in estimated expenses, and only $1,753 in median rent, producing a projected cash-on-cash return of negative 9.87% and roughly negative $643 per month. That is a materially negative carry at current financing costs, and any investor who needs the property to service itself from day one will find Johnston difficult to pencil. Home prices are essentially flat, down 0.59% year over year, which removes near-term appreciation as a compensating factor.

The investor profile this market fits is narrow at current rates. A cash buyer or an operator with a cost basis well below the median, through value-add acquisition or off-market sourcing, can close the gap meaningfully: remove the mortgage and the cap rate of 4.02% becomes the actual return floor, with upside from rent growth if the Raleigh metro's gravitational pull continues to push tenants eastward into Johnston. An appreciation buyer buying at the median and hoping for price gains faces a flat price trend and an affordability index of only 57, meaning the pool of potential buyers is already strained, which limits near-term price appreciation. The market is not structured for a passive, leveraged buy-and-hold at full retail price right now, but a value-add operator who can acquire at a 10-15% discount and push rents modestly has a clearer path to positive cash flow.

Johnston County's rental demand story is tied directly to its position on the southeastern edge of the Raleigh-Durham metro. A population of 219,042 represents meaningful household depth, and the county has benefited from residents priced out of Wake County seeking lower-cost alternatives while remaining commutable to Research Triangle employment centers. That dynamic is real and has driven Johnston's price appreciation cycle over the prior decade, but it also explains the current affordability strain: prices moved faster than local incomes, and now the market is digesting that gap.

The combined monthly tax and insurance burden on a median-priced acquisition comes to $317, which is built into the $614 expense estimate above. The underlying property tax rate used here is 0.84% (a state-average effective rate from Tax Foundation 2024, with the standard caveat that actual Johnston County and township rates will differ). That rate is flagged as normal, and it is, sitting comfortably below the national average and not a material drag relative to other carrying costs. Insurance at 0.28% is similarly unremarkable. Neither figure creates an outsized headwind, which is a modest positive relative to high-tax states where combined tax and insurance alone can consume 40-50% of gross rent.

The primary risk in Johnston is concentration, specifically the dependence on commuter demand from the Raleigh-Durham employment base. If remote work patterns shift back toward office, that is a positive for Johnston demand. If a major Triangle employer contracts, Johnston is more exposed than a county with diverse local job creation. Price-to-rent compression is also a risk: at a 6.19% ratio, there is not enough margin at current financing costs to absorb rent softness without turning a bad cash-flow position into a worse one. There is no vacancy or regulatory data provided here, so no claims are made on those dimensions.

Against its neighbors, Johnston's 6.19% rent-to-price ratio is the strongest in the comparison set. Franklin County sits at 6.03% with a higher median price of $354,406, Moore County at 5.44% with a $406,616 median, and Union County at 5.55% with a $445,007 median. Tyrrell and Chowan carry lower medians but lack rent data and score at 54 and 53 overall respectively, one point below Johnston at 54. On a pure yield basis, Johnston beats every named neighbor with rent data. The case for choosing Johnston over Franklin is straightforward: slightly better rent-to-price ratio at a lower price point with a comparable overall score. The case for Johnston over Moore or Union is even cleaner on yield, though both of those counties likely carry different appreciation dynamics tied to their respective markets. An investor optimizing for the best attainable rent-to-price ratio in this part of North Carolina, while keeping the purchase price below $350,000, should put Johnston at the top of the shortlist, with the clear-eyed understanding that positive leveraged cash flow still requires either a below-market purchase or patient rate-environment improvement.
