I’ve Been Advising Wealthy Families, Time for 100-Year Plans

As 2026 unfolds, the world of family offices is recalibrating how it bets on real estate. A broad market shift—rising rates, tighter lending standards, and a sweeping transfer of wealth across generations—has many portfolio managers asking whether a 100-year plan still holds up in a fast-changing economy. The answer, officials say, is yes—but with sharper guardrails and a more disciplined approach to risk, liquidity, and governance.

Market Backdrop: A Turbulent Start to 2026

Across high-net-worth circles, the refrain is similar: the landscape has shifted from a decade of easy credit and steady appreciation to a period of selective opportunities and structural headwinds. Real estate remains a cornerstone for many families, yet the path forward isn’t a straight line. Office and retail spaces are correcting in some markets, while demand for multifamily housing and certain industrial assets remains resilient. The net effect is a more nuanced real estate cycle, where timing and location matter as much as leverage and cost of capital.

Industry executives say the Great Wealth Transfer is accelerating portfolio recalibrations. Generational change means new priorities—preserving capital, funding philanthropy, and sustaining intergenerational wealth over a century—are taking center stage. In effect, today’s market requires more than a static blueprint; it demands a living thesis that can bend without breaking when external shocks hit the economy.

The 100-Year Plan in a Shifting World

The notion of a 100-year plan has long appealed to family offices for its emphasis on patient capital, governance, and disciplined rebalancing. When markets gyrate or a crisis hits, a long horizon can shield portfolios from knee-jerk reactions and allow for opportunistic moves when dislocations appear. However, long horizons require ongoing review. As leaders of these offices explain, a 100-year plan is not a fixed schedule but a living framework that must adapt to changing risk, liquidity needs, and macro trends.

“i’ve been advising wealthy families for decades,” says a veteran advisor who has guided several multigenerational pools of capital, “and the market today is a reminder that a static plan is a recipe for underperformance. The 100-year framework is valuable, but it only works if you refresh your thesis with every cycle.”

The retrenchment in some real estate markets is a critical test for these plans. Asset allocations must withstand higher borrowing costs, more stringent underwriting, and slower cap-rate compression in certain sectors. That combination can squeeze returns if the plan relies too heavily on a single cohort of assets or a single funding source. Yet the same forces can unlock opportunities in others—especially segments with durable income streams and strong demographic tailwinds.

Real Estate’s Role: Cornerstone With New Guardrails

Real estate has long served as a stabilizing ballast for family offices because it blends tangible value with potential inflation hedging and income generation. A 2025 Citi Private Bank report highlights why the asset class remains attractive: direct real estate accounts for roughly 10% to 15% of total family office assets, and for those managing at least $500 million, real estate is among the fastest-growing allocations. The data suggest real estate is not a passing phase but a strategic anchor—albeit one that must be managed with an eye toward evolving financing, risk tolerance, and estate planning considerations.

That said, the portfolio implications are nuanced. Office- and retail-focused properties in certain markets are undergoing structural adjustments—from shifting commuter patterns to evolving consumer behavior. On the other hand, well-located multifamily developments and logistics centers continue to draw capital because they offer shorter-income lifespans and robust demand. The interplay between these segments is shaping a rebalanced real estate program that emphasizes diversification by asset class, geography, and investment stage.

Borrowing costs remain a central stress test. With lenders applying tougher standards post-pandemic and inflation slowly retreating, debt terms have grown more selective. That reality tilts the risk-return calculus toward longer hold periods, higher equity cushions, and a willingness to fund value-add strategies with longer time horizons. In practice, this can translate into more private deals, partnerships with public entities, and a greater appetite for development within a carefully staged risk framework.

Key Data Points for 2026 Real Estate Plans

• Direct real estate allocations in family offices: roughly 10%–15% of total assets, per Citi Private Bank’s 2025 findings.
• Asset growth: real estate is among the fastest-growing categories for offices managing $500 million or more, signaling persistent demand for tangible, income-generating assets.
• Market mix: office and retail assets in flux in several regions, while residential development and logistics assets show resilience in demand.
• Debt environment: lending standards have tightened, with longer diligence periods and higher equity cushions preferred by lenders and lenders’ partners.
• Long-horizon planning: 100-year plans emphasize governance, diversified sources of capital, and adaptable investment theses rather than fixed, time-bound bets.

What Families Should Do Now: Practical Steps for a Longer View

For families executing a 100-year plan, the current climate demands a balanced, resilient playbook. The goal is to preserve capital while maintaining the flexibility to capitalize on structural shifts and new opportunities. Below are action items being discussed in private offices around the country.

• Revisit the thesis regularly. Implement quarterly reviews that test assumptions against macro data, municipal budgets, and demographic projections. It’s not enough to set a thesis and forget it; the plan must bend without breaking.
• Stress-test liquidity and contingencies. Build liquidity buffers that can weather interest-rate spikes or liquidity squeezes in private markets. Consider alternative financing strategies that reduce reliance on conventional lenders during tightening cycles.
• Optimize debt and equity mix. Use conservative leverage and layered financing structures to protect downside while preserving upside from value-add plays in well-chosen markets.
• Diversify across geographies and sectors. A mix of urban cores, secondary markets, and logistics corridors reduces exposure to a single local shock and broadens the set of potential exits.
• Strengthen governance and transparency. Multi-generational families require robust decision rights, dispute resolution mechanisms, and clear policies on liquidity events and charitable allocations.
• Integrate climate and resilience into every deal. Physical risk assessments, insured protection, and adaptive reuse strategies can cushion portfolios against weather-related losses and regulation shifts.
• Plan for successor leadership and education. Proactive grooming and clear transition plans help avoid misalignment among heirs and ensure the investment thesis travels across generations.

Balancing Opportunity With Caution

The drive to protect and grow wealth across generations means embracing a pragmatic optimism. The 100-year plan remains a powerful lens through which to view real estate and other illiquid assets. It encourages patience, discipline, and a bias toward high-quality holdings with durable cash flows. But it also demands humility: markets will surprise, cycles will deviate, and unforeseen events will test even the best-laid strategies.

One advisor summarized the sentiment as 2026 moves forward: “The wealth transfer isn’t just about passing capital—it’s about passing a way of thinking.” The key, he added, is to ensure the plan supports the family’s values, preserves dignity, and creates opportunities for descendants to participate in the decision-making process. In practice, that means treating the 100-year plan as a living document—one that adapts to regulatory shifts, rising sustainability expectations, and a marketplace that rewards those who stay patient without becoming complacent.

Closing Thoughts: A Revised Blueprint for Generations

Real estate will continue to anchor many family offices as they navigate a world of higher financing costs and evolving demand. The big question remains: can a 100-year plan withstand the pressures of today’s economy while remaining flexible enough to absorb tomorrow’s shocks? The early answer from industry veterans is affirmative—with a caveat: the plan must be routinely reevaluated, backed by rigorous data, and anchored in clear governance. For i’ve been advising wealthy clients for decades, the exercise isn’t about predicting every twist of the market. It’s about building a framework that endures, even as markets rewrite the rules along the way.
