Johnston County has been one of North Carolina's fastest-growing counties for years, but the construction pipeline that fed that growth is showing signs of a significant pullback. Builders pulled permits for nearly 12 percent fewer housing units in the first half of 2026 compared to the same period in 2025, according to local building department data. For buyers considering a home in Clayton — and especially a premium resale property like 297 Bonaventure Dr in Portofino — this trend has direct implications for pricing, competition, and timing.
Why Construction Is Slowing
The slowdown is not a demand problem. Johnston County's population continues to grow as families and professionals seek more space and better value than Wake County offers. The issue is on the supply side: builders are facing a convergence of headwinds that have made launching new projects less attractive.
- Elevated mortgage rates. With rates remaining higher than the historic lows of 2020 and 2021, builders are seeing slower presales on new phases. Many buyers are waiting for rate relief before committing to a new construction timeline.
- Rising material and labor costs. Lumber prices have fluctuated, and skilled labor remains expensive and hard to find in a market where construction demand across the Triangle is still elevated. Builders are compressing margins to keep prices competitive, and some are choosing to slow their pace rather than build at thinner margins.
- Tighter lending conditions. Commercial construction financing has become more restrictive as banks and credit unions reassess their exposure to residential development. Smaller builders in particular are finding it harder to secure the capital needed to start new phases.
- Lot availability. Developed lots in desirable communities like Portofino are finite. As the best locations are built out, remaining lots in new communities may be less desirable or more expensive to develop.
How the Slowdown Affects the Resale Market
When new construction slows, the pressure shifts to the existing resale market. Buyers who might have purchased a new home in a developing community are instead competing for move-in-ready properties in established neighborhoods. For Clayton, this dynamic benefits well-maintained homes in desirable communities like Portofino for several reasons:
Reduced Competition From New Inventory
If builders are not adding new supply at the same rate, the overall inventory of homes for sale grows more slowly — or shrinks relative to demand. In a county that is still adding population, that imbalance supports resale prices. Existing homes become the primary option for buyers who cannot wait for new construction that may be delayed or never built.
Premium on Move-In Readiness
New construction homes often come with their own timeline: three to six months from contract to completion, plus the uncertainty of supply chain delays. For buyers who need to relocate by a specific date — for a job, a school start, or a lease expiration — a move-in-ready home like 297 Bonaventure Dr becomes the more practical choice. And in a market where new supply is tightening, the willingness of buyers to pay a premium for immediate occupancy increases.
Finished Lots Gain Value
One of the overlooked consequences of a construction slowdown is that finished lots in established communities appreciate faster than raw land in developing areas. A half-acre lot in Portofino — with mature trees, utility connections, and a fully finished home already in place — holds inherent value that a raw lot in a yet-to-be-developed subdivision does not. As the cost of developing new lots rises, the relative value of existing developed lots increases.
What This Means for Portofino Homeowners
For owners of homes in Portofino, the construction slowdown is, on balance, a positive signal. It means less competition from fresh inventory in the immediate area. It means that the premium finishes, gated setting, and resort amenities that set Portofino apart are not being replicated in new developments at the same rate. And it means that the scarcity of large homesites — the half-acre lots that define the community — is becoming more pronounced with every passing quarter.
For buyers considering 297 Bonaventure Dr specifically, the timing is worth noting. The home is being offered at a moment when new construction in Johnston County is pulling back, when mortgage rates are elevated but showing signs of eventual stabilization, and when the community amenities — pools, trails, equestrian center — are in their prime summer season. Buyers who act now are purchasing into a market where the supply dynamics are moving in their favor as long-term owners, even if the short-term rate environment is not ideal.
Looking Ahead: 2027 and Beyond
Construction cycles are cyclical by nature. The current slowdown is likely to be a period of adjustment rather than a long-term contraction. Johnston County's fundamentals — population growth, job creation, infrastructure investment, and quality of life — remain strong. When interest rates eventually ease and builder confidence returns, new construction will pick back up. But the homes built during the current slowdown may carry higher price tags to account for accumulated cost increases, which would further support the value of existing homes purchased now.
For buyers who are weighing the decision to purchase in Clayton, the construction data adds one more piece of evidence in favor of acting sooner rather than later. The supply of premium homes in gated communities with half-acre lots is not growing — and in the current environment, it is effectively shrinking.
