When to Transition from Single-Family to Multi-Family Offices
Weigh costs, specialist access, scalability and liquidity events to decide if moving from an SFO to an MFO is right for your family's wealth.
Transitioning from a single-family office (SFO) to a multi-family office (MFO) can save costs, improve access to expertise, and provide better scalability for families managing wealth. SFOs work well for families with assets over $200 million but can become costly and inefficient for smaller portfolios. MFOs, on the other hand, offer shared resources, broader investment opportunities, and access to specialized services, making them a better fit for families with $25–$100 million in assets.
Key Takeaways:
- Costs: SFOs cost 1–2% of assets annually, while MFOs reduce costs by pooling resources.
- Expertise: MFOs provide access to specialists (e.g., tax, estate planning) that SFOs may lack.
- Investment Opportunities: MFOs offer institutional-grade investments unavailable to smaller SFOs.
- Scalability: MFOs adapt quickly to growing family needs or major financial events.
When to Switch:
- Asset Size: If your assets fall below $200 million, MFOs are often more cost-effective.
- Family Complexity: Expanding family structures strain SFOs, making MFOs a better option.
- Financial Events: Business sales or inheritances often require the resources of an MFO.
Problems with Single-Family Offices
High Operating Costs
Running a single-family office (SFO) doesn't come cheap. Operational expenses typically range from 0.5% to 1.5% of assets under management each year. When you add external advisors and other services, those costs can climb to 1% to 2% annually [9][3]. For context, personnel costs alone make up 50%–60% of the budget [9]. A seasoned investment manager earns at least $300,000 annually, and if they have private equity experience, that number increases significantly. Even a small team - say, two professionals and four support staff - can cost close to $2 million a year [10].
The Citi 2025 Global Family Office Report shows that about 27% of family offices spend more than 1% of their assets under management annually. For a family with $200 million in assets, this translates to $1 million to $3 million annually [9].
Things get even pricier when families expand their services to include philanthropy, concierge services, or next-generation education. These add-ons drive up legal, technology, and monitoring costs [9]. Some functions, like tax preparation, also face seasonal inefficiencies, with periods of intense activity followed by downtime [10]. For families looking to switch to multi-family offices, managing these ballooning costs often becomes a top priority.
And it’s not just about the money - these high costs also make it harder to scale expertise.
Difficulty Scaling and Finding Specialized Expertise
Single-family offices often operate in a staffing gray zone: they’re too small to attract top-tier experts but too complex to rely on generalists. Over 60% of SFOs have fewer than five employees, and 52% operate with just one to three staff members [6][9]. This lean setup creates a major vulnerability - if a key professional leaves, retires, or is unavailable, critical functions can grind to a halt [6].
"A single-family office is born out of strength, but it can quietly become a point of weakness if left to stand alone." – Justin Bakewell, Head of Client Strategy, Pitcairn [6]
Recruiting and retaining talent is another uphill battle. Many SFOs struggle to compete with larger firms that offer clear career paths and professional development opportunities [6][12]. Hiring full-time specialists for niche areas like international tax planning or private equity is often cost-prohibitive, and relying on generalists can leave expertise gaps [10]. Small teams also risk falling into "intellectual cocoons", as Douglas McCreery, CEO of CM Wealth, puts it. This isolation can lead to groupthink and decisions influenced by family biases rather than objective analysis [10][13].
The staffing challenges don’t stop there - they also limit access to premium investments.
Restricted Investment Access
Single-family offices often miss out on top-tier investment opportunities. Without the pooled resources of multi-family offices, SFOs typically lack access to institutional-grade deals and high-quality private equity or venture capital investments [7].
"For smaller SFOs, no one will answer the phone, let alone let you into these top-tier [investment] opportunities." – Philipp Lennertz, Managing Partner, Lennertz & Co. [7]
A small team makes this problem worse. With fewer hands on deck, SFOs struggle to conduct the rigorous due diligence needed for complex private market deals [6]. They also can’t justify the steep research and specialist costs that multi-family offices can spread across multiple clients [13].
This lack of expertise can lead to risky investments. The collapse of Sam Bankman-Fried's crypto firm, FTX, serves as a cautionary tale. It exposed how weak governance in SFOs, combined with limited resources, can result in poor oversight and a failure to ask the tough questions [14]. Without specialized knowledge, SFOs are more vulnerable to "zombie funds", overpriced assets, and overly concentrated portfolios that could benefit from better diversification [10]. These limitations often push families to seek broader investment opportunities outside the SFO model.

Advantages of Multi-Family Offices
Multi-family offices (MFOs) tackle the high costs and operational challenges often associated with single-family offices by sharing expenses across multiple families. Instead of one family shouldering the full financial burden of salaries, technology, and infrastructure, MFOs distribute these costs. This shared model significantly reduces operating expenses, bringing them down to 35–55 basis points - much lower than the 98 basis points (around $1.8 million annually) that a family with $480 million in assets might spend on a single-family office [15].
Lower Costs Through Shared Services
Staff salaries are typically the largest expense for family offices. By dividing the cost of skilled professionals across several families, MFOs make hiring top-tier talent more affordable. For example, the $300,000 annual salary of an investment manager is shared, allowing families to access high-level expertise without bearing the full expense [10]. Similarly, technology costs - such as Bloomberg terminals, private-equity data feeds, and wealth-aggregation software - are also spread among participating families [15].
Beyond operational savings, MFOs use their combined assets under management to negotiate better terms. A $2 billion MFO, for instance, can secure hedge fund fees below 80 basis points, compared to the 1.5% fee a $200 million single-family office might pay [15]. This bargaining power extends to vendor contracts, cybersecurity systems, and regulatory compliance. Families with as little as $25 million in assets can access these institutional-level pricing benefits, which are typically available only to those managing $100 million or more [3][7].
"The platform allows the family to benefit from the services of a family office, without having to invest in the personnel and staff by themselves." – Mike Tan, Global Head of Wealth Planning and Family Advisory, Standard Chartered [7]
Access to More Specialists and Services
MFOs employ a diverse team of professionals with advanced credentials like CPAs, JDs, and CFAs, offering expertise in areas such as complex tax structuring, sophisticated estate planning techniques (e.g., Grantor Retained Annuity Trusts), and managing entities like LLCs and S-corps [18][20]. These specialists also provide guidance on family governance, succession planning, and niche services like cybersecurity, identity theft protection, and insurance for unique assets such as art collections or wine cellars [18][19].
For business owners preparing for liquidity events, MFOs deliver tailored support, including pre-sale modeling, valuation analysis, and strategies for transferring ownership [17][18]. This level of service is particularly helpful for families dealing with multi-generational wealth transfers or managing assets spread across different regions.
Better Investment Networks and Flexibility
One of the standout benefits of MFOs is access to high-caliber investment opportunities. By pooling resources from multiple families, they gain entry to deals typically reserved for large institutions. These include investments with top private equity firms like Kleiner Perkins, exclusive Series B robotics funding rounds, and European infrastructure projects [15][7]. Even families with $25 million in assets can participate in opportunities that are usually out of reach for smaller investors [5].
Flexibility is another key strength of the MFO model. MFOs are operationally ready from the start, eliminating the need for families to spend years recruiting staff or building infrastructure [7]. They can quickly scale services up or down based on a family’s needs. For example, during periods of rapid asset growth, MFOs can expand their offerings instantly. Conversely, in slower market conditions, families avoid the burden of fixed costs for underutilized staff.
"A strength of the multi-family office model is its flexibility. Investment strategies and operations can be scaled up and down when the need arises." – Vikash Gupta, CEO, VAR Capital [16]
This adaptability is especially valuable during major financial transitions, such as responding to geopolitical changes, adjusting to macroeconomic shifts, or managing complex, multi-location family strategies. The MFO structure accommodates these evolving needs without the logistical challenges of hiring or downsizing staff [16][7]. These benefits make MFOs an appealing choice for families considering a shift from single-family office management.
When to Switch to a Multi-Family Office
Deciding to transition from a single-family office (SFO) to a multi-family office (MFO) often comes down to three key factors: balancing asset size against costs, managing increasing family complexity, and addressing major financial events. When these challenges arise, maintaining an SFO might no longer make financial or operational sense.
Asset Size and Cost Analysis
SFOs are typically a good fit for families with assets exceeding $200 million. However, families with assets in the $30–100 million range often find themselves overpaying for the personalized services these offices provide [8][2]. As wealth gets distributed across multiple generations, the costs of sustaining a dedicated family office can become prohibitive. Neil Shapiro, Managing Director at TAG Associates, puts it this way:
"As the branches of the family grow, the wealth can be distributed. Instead of one family with $500 million in assets, there might be ten families with $50 million in assets... the cost of running an SFO is no longer economical" [4].
In fact, only 67% of family office participants believe their current setup delivers "value for money" [21]. As family structures expand alongside their assets, the operational strain of running a single-family office often increases.
Growing Family Complexity
Many SFOs are originally designed to serve just a few households - typically four or five. When asked to support a dozen or more, these offices often reach their limits [8]. Andy Busser, Managing Director of Strategy at Pitcairn, highlights this issue:
"The reality is that a family office set up to serve four or five households will always struggle to sustainably service a dozen or more" [8].
With over 60% of single-family offices operating with fewer than five employees [6], gaps in service can emerge as families grow. This is especially evident in areas like succession planning and next-generation education, where only 42% of family offices are rated effective at the former, and just 39% of participants express satisfaction with the latter [21]. Transitioning to an MFO can help address these shortcomings by offering broader resources and expertise tailored to the needs of a growing family network.
Major Financial Events Requiring Quick Scaling
Significant liquidity events - such as business sales, IPOs, or large inheritances - often introduce new complexities that require immediate attention and specialized expertise [22]. A lean SFO may struggle to handle the sudden surge in demands, whether it’s pre-deal planning or post-event management. Leadership transitions can also pose risks; the retirement of a long-serving CEO or CIO without a clear successor can leave the office vulnerable. Additionally, rising technology and cybersecurity costs add another layer of inefficiency for smaller SFOs. With over 25% of international family offices having experienced a cyberattack [8], the shared infrastructure of an MFO can provide better security and operational resilience.

Single-Family Office vs Multi-Family Office: Cost, Services, and Scalability Comparison
Cost, Services, and Scalability Differences
Deciding between a single-family office (SFO) and a multi-family office (MFO) largely depends on costs, services, and scalability.
Cost differences are stark. Running an SFO means covering all expenses yourself - everything from salaries and benefits to office space, technology, and compliance. Annual operating costs start at $1 million and can climb past $10 million for larger setups [23][24]. On the other hand, MFOs distribute these expenses across multiple families, making them more cost-effective. Paul Karger and Wes Karger, Co-founders of TwinFocus Capital, highlight this point:
"The cost to run and maintain a SFO is astronomical vis-à-vis the cost associated with retaining a MFO and investing alongside other affluent families" [13].
Service offerings vary significantly. SFOs excel in providing personalized, dedicated attention, as the team is deeply familiar with a single family's history and objectives. MFOs, however, bring together a wide range of specialists - like experts in international tax, impact investing, and regulatory compliance - resources that might be too expensive for one family to maintain on its own [5][2]. Additionally, MFOs often offer access to institutional-grade investment opportunities that SFOs might struggle to match.
Scalability is another key distinction. Building an SFO takes time - often years - to recruit staff and establish the necessary infrastructure [7][25]. In contrast, MFOs are ready to operate right away with established teams and systems. When a major financial event occurs, such as a business sale or large inheritance, an MFO can quickly expand its services. An SFO, especially one with a lean structure, may find it challenging to adapt as quickly.
| Feature | Single-Family Office (SFO) | Multi-Family Office (MFO) |
|---|---|---|
| Minimum Wealth | $100M–$250M+ [23][3] | $10M–$25M+ [3][24][5] |
| Annual Cost | $1M–$10M+ (100% borne by one family) [23][24] | 0.5%–2% of AUM (shared across families) [5][24] |
| Setup Time | Years to build team and infrastructure [7] | Immediate; ready to operate [7] |
| Control Level | Absolute (direct family control) [24] | Delegated; family provides oversight [3] |
| Expertise Access | Limited to in-house team [25] | Broad pool of interdisciplinary specialists [5][2] |
| Investment Opportunities | Direct deals [3] | Pooled institutional-grade access [3][7] |
| Scalability | Difficult; requires new hires for new needs [25] | High; access to existing specialist teams [5] |
For families with assets between $25 million and $100 million, MFOs often make more sense. They combine shared costs with access to high-level services and expertise [3][1][24]. This dynamic creates a compelling case for families considering a transition from an SFO to an MFO structure.
How to Transition to a Multi-Family Office
Review Your Current Setup and Identify Gaps
Start by analyzing your single-family office (SFO) for signs of strain. Key indicators include leadership turnover without a clear succession plan, generational disagreements, or an increasing number of households that the current team cannot effectively support [4][8]. As Andy Busser, Managing Director of Strategy at Pitcairn, explains:
"A departing SFO leader is an opportunity to evaluate the role an SFO plays in supporting a family through future generations" [8].
Take a close look at your operations. Can your team handle complex tasks like managing international properties, executing private equity deals, or navigating intricate tax structures? If your investments feel stagnant due to limited connections, it might be time to reconsider your approach [4][26]. Also, assess your technology and cybersecurity setup, as these are common areas of vulnerability [8].
Another critical area to examine is reliance on a few key employees. If crucial knowledge is concentrated in just one or two individuals, you risk operational disruption should they leave [6]. Lastly, prepare a three-year projection of operational costs, including salaries, technology, and compliance expenses, to determine if your SFO model remains sustainable [26].
Once you've identified these gaps, it's time to explore multi-family offices (MFOs) that can address them effectively.
Research and Choose the Right Multi-Family Office
With a clear understanding of your SFO's challenges, start researching MFOs that align with your needs. Prioritize firms that operate with fiduciary responsibility and transparency. This means they must prioritize your family's interests and avoid conflicts of interest [27][28]. Request detailed fee schedules to understand costs clearly, including setup fees, transaction charges, or fees for specialized services like governance workshops [27][28]. Ensure the firm’s policies prevent them from promoting proprietary products.
Look for an MFO that offers a broad range of services. A good fit will provide support in areas such as investment management, tax and estate planning, philanthropy, family governance, and even concierge services [27][28]. Evaluate the team’s expertise - experienced professionals in investment management, wealth planning, and tax analysis are essential [27]. Ask for a demo of their client portal to ensure it provides real-time financial updates and secure communication tools [28].
The MFO should not only meet technical requirements but also align with your family’s values and long-term vision. A shared philosophy can help establish a lasting partnership across generations [27][3]. Additionally, confirm that the firm has strong cybersecurity measures, such as multi-factor authentication, regular penetration testing, and SOC 2 IT compliance, to protect sensitive data [29][30].
Implement the Transition
Transitioning to an MFO requires a phased approach. Plan for 3–6 months to conceptualize and structure the move, another 3–6 months to address legal and regulatory requirements, and 6–12 months for full integration of your team and assets [30]. To ensure continuity, consider a "shared single-family office" model where trusted SFO employees transition to the MFO platform [6]. As Justin Bakewell, Head of Client Strategy at Pitcairn, notes:
"The real measure of success isn't how long you hold onto a structure - but how gracefully you evolve it" [6].
Establish governance early by creating a family charter that outlines your mission and values. This ensures the MFO’s investment strategies align with your family’s legacy [29][30]. Integrate your existing reporting systems with the MFO’s advanced data tools, enabling seamless data aggregation across custodians and replacing outdated manual tracking with on-demand reporting [29].
Finally, measure the MFO’s performance beyond financial returns. Consider how well they support family unity, educate heirs, and preserve your legacy - factors often referred to as "return on governance" [28][3].
Conclusion
Finding the right structure for your family office is all about aligning it with your family's needs and long-term goals. Some experts suggest that an SFO may only make financial sense when assets reach around $750 million [11]. However, shifts in family dynamics or leadership might indicate it's time to reassess your setup.
It’s wise to evaluate your current structure before problems arise. Pay attention to red flags like a stagnant investment approach or heavy reliance on a few key employees [6]. Taking a proactive stance can pave the way for a smoother transition. As Justin Bakewell from Pitcairn puts it:
"The real measure of success isn't how long you hold onto a structure - but how gracefully you evolve it" [6].
A thoughtful transition plan allows you to retain what works while building on new opportunities. For instance, families often integrate their trusted SFO team into an MFO model, preserving institutional knowledge while benefiting from expanded expertise, better technology, and access to institutional-grade investment options [6]. This strategy helps tackle the scalability and cost challenges that can come with running an SFO as family needs grow.
When navigating these transitions, having expert advisory support can make all the difference. Phoenix Strategy Group (https://phoenixstrategy.group) offers a range of services - like fractional CFO support, FP&A systems, and M&A advisory - to help organizations manage growth, streamline operations, and confidently handle structural changes.
Your family office should evolve to support your long-term success. Regularly reviewing your setup ensures it stays aligned with your goals and adapts to changing circumstances.
FAQs
How do I know if my SFO is too expensive for my asset level?
Evaluating whether your single-family office (SFO) is worth the investment comes down to balancing its costs against the benefits it provides. SFOs often come with high expenses, which usually make sense only for families with extensive asset bases. If running your SFO is eating into your overall wealth management strategy or lowering its effectiveness, it might be time to consider whether a multi-family office could serve you better.
What control do I give up when moving from an SFO to an MFO?
When moving from a single-family office (SFO) to a multi-family office (MFO), you give up some of the direct control you may have had over decisions and day-to-day management. In an MFO setup, responsibilities are shared among several families and a team of professionals. This often results in more uniform procedures and a collaborative approach to governance.
How long does an SFO-to-MFO transition usually take?
The shift from a single-family office (SFO) to a multi-family office (MFO) usually spans several months to a year. The duration largely hinges on how intricate the family's financial requirements are and the overall scale of the transition.
