If you are thinking about buying a rental house in Johnston County, you are looking in a market with real momentum. This county is growing fast, sits along key highway corridors, and offers a mix of commuter convenience and suburban space that many renters want. If you want to understand where the numbers look strongest, what risks to plan for, and how to evaluate towns like Clayton, Smithfield, Selma, Benson, and Four Oaks, this guide will help you sort through it. Let’s dive in.

Why Johnston County draws rental demand

Johnston County continues to benefit from growth tied to the greater Raleigh area. Census QuickFacts estimates the county population at 256,448 in 2025, which is up 18.7% from the April 1, 2020 base. County materials also note that US 70, I-95, and I-40 run through the county, which helps explain why commuter-oriented housing remains important here.

That growth matters for single-family rental investors because it supports a broader renter pool. QuickFacts reports 85,591 households, a 76.1% owner-occupied housing rate, and a median household income of $83,384. That income figure sits above the North Carolina median of $72,388, which can support rent-paying capacity in many parts of the county.

Family-oriented housing also stands out in the local demand picture. Johnston County Public Schools says it serves more than 37,000 students and has been adding about 500 students per year, with some schools capped because of growth. For investors, that points to ongoing demand for practical detached homes that offer space and predictable access to major commuting routes.

Employment trends add another layer of support. The county had 4,151 employer establishments and 49,067 total employment in 2023, with employment up 3.8% year over year. Public data also highlights health care and social assistance, retail, and transportation and warehousing as notable sectors, which fits a market where stable, commuter-friendly rentals can perform well.

What the countywide numbers say

Johnston County's current public benchmarks suggest a market that can work for small-scale rental investing, but only with careful math. Zillow's public data shows a typical home value of $344,260, a median sale price of $343,667, and an average asking rent of $1,800. Homes are also going pending in around 26 days, which tells you purchase-side competition can still be meaningful.

It is important to compare the right numbers. Census QuickFacts reports a lower median gross rent of $1,146 for 2020 to 2024, but that is not the same as current asking rent. If you are underwriting a deal today, current asking rent is the more useful starting point, while older rent measures can help provide broader context.

Using those countywide public benchmarks, rough gross rent yield comes out around 6.3%. That is only a headline number before vacancy, property taxes, insurance, maintenance, repairs, and capital expenses. In other words, the market can make sense, but not every listing will pencil out.

Best Johnston County towns to compare

Clayton: scale and commuter appeal

Clayton is the largest town in this public comparison set, with a 2024 Census estimate of 31,732 residents. It also carries the highest home-value benchmark among the towns reviewed, with a typical home value of $366,558 and an average rent of $1,919. Public rental inventory is also the deepest here, with 293 rentals shown in current public data.

For you as an investor, Clayton often means stronger commuter appeal and more visible rental activity, but the tradeoff is tighter price-to-rent math. Rough gross yield is about 6.3%, which is solid but not especially forgiving if your maintenance budget, vacancy assumptions, or financing costs run high. Clayton may appeal more if you value scale, newer housing choices, and broad renter demand over maximum yield.

Smithfield: balanced entry point

Smithfield offers a middle-ground option for many small investors. The town's 2025 population estimate is 13,114, and public benchmarks show a typical home value of $294,547 with an average rent of $1,799. Homes in this range can offer a more approachable entry point than Clayton while still sitting in a meaningful local hub.

The rough gross yield here is about 7.3%, which is one of the stronger figures in the county data set. That does not guarantee better returns, but it does suggest that Smithfield can offer more breathing room in your numbers if you buy carefully. For an investor who wants a stable, manageable single-family rental without stretching too far on price, Smithfield deserves a close look.

Selma: lower price, stronger headline yield

Selma sits toward the lower-cost end of the county comparison. Public benchmarks show a typical home value of $276,411 and an average rent of $1,650. The rough gross yield works out to about 7.2%, which puts it near the top of the towns reviewed.

That can make Selma attractive if your goal is stronger income potential relative to purchase price. At the same time, lower-cost markets require disciplined review of property condition, likely repair needs, and realistic vacancy assumptions. A strong headline yield only helps if the home is rentable and ongoing costs stay within reason.

Benson: moderate pricing and moderate rents

Benson falls into a more middle-of-the-pack range. Public data shows a typical home value of $319,127 and an average rent of $1,595. That produces a rough gross yield near 6.0%, which is lower than Smithfield or Selma based on the current benchmarks.

That does not mean Benson should be ruled out. It means you may need to be especially selective about purchase price, property updates, and target rent. In a market like this, your individual deal matters more than the town average.

Four Oaks: affordable entry with careful screening

Four Oaks shows a typical home value of $312,747 and an average rent of $1,695. Rough gross yield comes out around 6.5%, which places it between the county average and the stronger-yielding towns in the set. Public rental inventory appears smaller here, with only five rentals shown in the current snapshot.

For you, that may mean less visible competition but also less market depth. In a smaller rental pool, tenant screening, home condition, and pricing discipline become even more important. Four Oaks can be worth considering if you find a well-positioned property at the right basis.

How to think about yield versus stability

One of the biggest mistakes new investors make is chasing the highest gross yield without thinking about the full picture. Lower-cost towns like Smithfield and Selma can look better on paper, and right now the public numbers support that view. Still, gross yield does not capture turnover, deferred maintenance, taxes, or the risk of overestimating rent.

Clayton shows the opposite pattern. It tends to offer stronger scale and commuter-family appeal, but its higher acquisition costs can compress returns. If you prefer a market with broader rental inventory and a larger local population, you may accept a tighter yield in exchange for that demand profile.

The right fit depends on your goals. If you want better headline cash flow, lower-cost submarkets may stand out. If you want a broader renter base and are comfortable with thinner margins, Clayton may still deserve a place on your list.

Costs that can change your cash flow

Property taxes

Johnston County's FY 2025-26 property tax rate is $0.52 per $100 of assessed value. The county says tax bills are mailed in July and due September 1, and revaluation took effect January 1, 2025. Municipal or fire district taxes can increase the effective bill depending on where the property sits.

This matters because tax changes can shift your monthly cash flow more than many new investors expect. A property that looked acceptable under older tax assumptions may feel tighter after reassessment. Before you buy, make sure you model taxes using current local information rather than old listing estimates.

Repairs and maintenance

In North Carolina, keeping a rental home in good and safe working order is not optional. The North Carolina Department of Justice says landlords must keep units in good and safe working order and follow state and local codes. For single-family homes, that means you should expect routine repair costs and plan for larger items over time.

This is especially important in a growing county with new and older housing competing side by side. If your rental is older or has not been updated, newer subdivision inventory can put pressure on pricing and tenant expectations. A conservative repair budget helps protect you from that risk.

Security deposit rules

North Carolina's Tenant Security Deposit Act sets clear rules for residential security deposits. Deposits must be held in a trust account, the tenant must be notified within 30 days where the deposit is held, and deposits for leases longer than month-to-month are capped at two months' rent. If you plan to self-manage, these rules need to be part of your setup from day one.

Operational mistakes can turn a decent investment into a stressful one. Even if your property is in a strong rental pocket, poor systems can create avoidable problems. Investors who treat compliance and recordkeeping seriously usually put themselves in a better position.

A simple way to underwrite a deal

If you are evaluating a Johnston County rental, keep your process straightforward and conservative. Public data can help you identify likely rent bands and compare towns, but your final decision should come down to the specific house, its condition, and your all-in cost. The safest approach is to use today's asking-rent environment and leave room for vacancy, repairs, and competition from newer homes.

A basic review should include:

• Estimated purchase price
• Expected market rent based on current local asking ranges
• Property tax estimate using current Johnston County rates
• Insurance estimate
• Vacancy allowance
• Repair and maintenance reserve
• Any expected upfront improvements
• Your target monthly cushion after core expenses

That framework helps you avoid buying based on optimism alone. In a county that is planning for continued growth over the next 25 years, supply and competition will remain part of the investment picture. A property only works long term if the numbers still make sense after you account for real-world costs.

What type of investor fits Johnston County best

Johnston County looks most appealing for the small-scale investor who wants a commuter-suburban single-family rental, not a highly speculative play. Public benchmarks point to purchase prices mostly in the high-$200,000s to mid-$300,000s and asking rents mostly in the mid-$1,500s to low-$1,900s. That profile can work well if you want a manageable house in a growth-oriented county and are willing to buy with discipline.

This market is less about chasing a perfect one-size-fits-all formula and more about choosing the right town and the right property. Smithfield and Selma may offer stronger yield at first glance. Clayton may offer broader renter demand and scale. Benson and Four Oaks can still make sense when price, condition, and rent line up.
