Renewal dynamics outperform new-lease pricing
Aging America Forces New Math For Apartment Investors
Aging America is not just a macro theme; it is beginning to alter the way apartment demand and revenue behave across major U.S. markets, according to a recent LinkedIn post by Greg Willett, chief economist and author of LeaseLock’s Market Insights. Drawing on shifts in median age that have been building for decades, Willett argues that demographic dispersion is now material enough to influence both leasing velocity and the structure of returns at the property level.
The U.S. median age has been climbing steadily since 1980, rising two to three years with each decennial census and now sitting just over 39. That slow grind upward is well known, but Willett highlights how unevenly it is distributed across states and why that matters to investors focused on apartments.
Utah’s median age stands at 32.5, the youngest in the country, while Maine’s is just under 45, the oldest in the nation.
“Variation across geographies is more pronounced than you might expect,” he writes, framing a demographic spread that now runs more than a decade between the youngest and oldest states.
Where the young adults are
The connection to multifamily is straightforward but often underweighted in underwriting models: young adults—and in particular young singles living alone—still account for an outsized portion of the nation’s renter base. That means state-level age skews are a rough but useful proxy for future renter household formation and, by extension, for the depth of the demand pool for new and existing assets.
As Willett puts it, because these households form such a large share of renters, differences in median age “impact apartment demand volumes and property operational strategies.”
In his post, Willett points to Utah, Texas, Colorado and Georgia as examples of markets where rapid economic growth and a sizable young adult population are combining to produce comparatively strong rental housing demand. For owners and developers, this dynamic reinforces what many see on the ground: stronger absorption and more leasing activity in younger markets that are still in household formation mode.
The implication is less about discovering new growth stories than about how demographic age profiles can help investors calibrate expectations between, say, a Sun Belt market with a low median age and a slower-growth region with an older population base.
The other side of the age curve
The flip side of the story emerges in New England and parts of the Mid-Atlantic. Willett notes that a higher concentration of older residents translates into “more shallow demand for rentals” across New England, where the median age in Vermont, New Hampshire, Connecticut and Rhode Island is almost as high as Maine’s and into states such as Delaware and Pennsylvania.
For capital targeting pure volume growth and rapid lease-up, those demographics suggest a more constrained runway. The renter pool is simply not being replenished at the same pace as in younger states, which can leave new supply more exposed and mute turnover-driven rent-roll opportunities.
Yet Willett’s analysis stops short of writing off older markets altogether. While an older renter base tends to dampen apartment demand, he argues that more mature households can improve the property’s revenue profile. These residents are more likely to renew expiring leases and less inclined to move as frequently as their younger counterparts. For operators, that stickiness can translate into steadier cash flows, lower turnover expense and a more predictable path for embedded rent increases.

Renewals versus new-lease growth
One of Willett’s key observations is that renewal dynamics have quietly outperformed new-lease pricing in recent years. According to his post, renewal lease rent growth has tended to surpass the price increases on new move-in leases.
At the same time, operators in renewal-heavy portfolios avoid unit turn costs when residents stay, preserving margins even when headline rent growth appears modest. That combination—above-market renewal growth and reduced frictional costs—can be particularly powerful in older renter cohorts, where propensity to stay put is higher.
For investors, this raises a familiar trade-off in a slightly new guise. Younger markets can offer stronger top-line demand growth and absorption, but often at the cost of higher turnover, more frequent unit turns and a greater reliance on new-lease trade-outs to drive revenue.
Older markets may deliver thinner demand but can support a more annuity-like cash flow profile if renewal behavior holds. The question becomes how to weigh marginal differences in demand volume against potentially higher-quality, lower-volatility income streams generated by older renter households.
Operational strategy, not just market selection
Willett’s post also hints at the operational levers available to owners and managers as age compositions shift. In younger markets, strategies that lean into active leasing, amenity-driven differentiation and dynamic pricing on new leases will matter more, given the churn in the renter base. In older markets, there may be more value in resident retention programs, customer-service investments and measured renewal pricing that maximizes lifetime value without pushing long-term residents out.
In both cases, the age profile is less a static descriptor than a signal for where operational emphasis should lie.
Because Willett’s analysis is framed at a high level, it does not attempt to quantify exactly how much of current performance dispersion can be explained by median age alone. Nor does it resolve the interaction between age, income, migration flows and supply pipelines that also shape local outcomes. Instead, it offers a lens that investors can add to their existing frameworks: median age as a directional indicator of demand depth and revenue stability.
For commercial real estate investors already parsing job growth, supply additions and policy risk, the argument is less about reordering the playbook than about ensuring demographics by age are not an afterthought.
The next phase of underwriting
The takeaway from Willett’s LinkedIn post is that demographic nuance is tightening its grip on apartment fundamentals at both the market and asset levels. A national median age above 39 signals a renter base that is aging alongside the broader population, even as certain states remain significantly younger than others.
For multifamily investors, that pattern suggests different sources of value depending on where capital is deployed: velocity and scale in younger, fast-growing states, versus income durability and renewal-driven growth in markets with older renter populations. As underwriting grows more competitive, age distribution may become a more explicit input in how investors size both risk and opportunity.
