How Much of a Family Office Portfolio Goes to Real Estate

No single share fits every office. Published averages for real estate run from 14.4% to 25% of family office assets, and individual offices sit anywhere from almost nothing to above 25% or 30%. The family’s own policy sets the number, and its governance document names who can change it, which is a narrower group than the people who approve a single deal.

Published averages run from 14.4% to 25% because they measure different things

Reported real estate shares of family office portfolios include 14.4% of assets in a global study of single-family offices, an average of 17% in another global report, 22.5% for direct ownership alone, and 25% for offices that invested in real estate at all.

The gaps come from population and definition. An average taken only across offices that hold property leaves out every office sitting at zero, which pushes the figure up. An average across all offices pulls it down. A direct ownership figure excludes fund interests and credit, so it answers a narrower question than a total real estate share.

Spread inside a sample matters as much as the mean. Allocations in the same population run from almost nothing to above 25% or 30%, so an average describes few actual offices.

For scale, the alternatives sleeve in the global single-family-office study averaged 45%, which makes real estate at 14.4% about a third of it. Private citizens, or retail investors, generally have less than 3% of their net worth in real estate, according to the CEO of JLL Capital Markets, Americas.

A further 44% of surveyed offices say they seek to increase real estate allocations. That is intent. Whether policy has room for it depends on the tests that follow.

A benchmark is a comparison point, and the family’s own policy is the target.

Policy authority and deal authority sit with different people

The percentage is a governance output. The first question in the field is who gets to decide what share of the portfolio goes to real estate, hedge funds, private equity or commodities. A written family office policy can name who may change portfolio allocations, who decides distributions to family members, and when the next generation receives capital.

Authority to approve a property deal and authority to move the allocation are separate powers. An investment committee can hold the first inside a band set by the second. A deal that stays inside the band is implementation. A deal that pushes funded exposure past the band needs the higher authority, however sound the property.

Distributions belong in the same document because they change the denominator. Cash paid out to family members shrinks total assets, so unchanged property holdings become a larger share of what remains.

Exceptions accumulate. If each approval carries a one-off exception and nothing updates the allocation record, total exposure drifts above policy while every individual file looks clean. The decision test is whether the record names the exception approver and shows the running total after each exception.

Capital raisers meet a version of this from the other side. An office already at its target in an asset class finds new offerings only anecdotally interesting. Interest from a principal therefore says little about capacity, because remaining room under the policy and authority to use that room are separate facts.

“Who gets to decide what percentage of the portfolio will be invested in real estate, hedge funds, private equity or commodities?”

Fixing the numerator and denominator before comparing to any benchmark

An allocation is a ratio, and both sides have to describe the same ownership. The first choice is the perimeter: the managed investment portfolio or all family wealth. The starting question is what the family’s wealth consists of, which usually includes property, operating businesses and securities. A securities-led office can show a low property share while the family holds substantial property outside it, and both numbers are true. Only the broader calculation measures the concentration of the whole family.

The numerator is the family’s economic interest in property after property debt. The denominator is the net equity of every asset inside the same perimeter. Dividing gross property value by net portfolio equity inflates the share, and the worked example below shows a gap of 10 percentage points from that single choice.

Embedded property is a second counting trap. If an operating business valuation already reflects the real estate it owns, adding the full property value again counts the same wealth twice. A schedule can show the embedded exposure for concentration purposes and reconcile it to the business value already recorded.

Unfunded commitments need their own line. A commitment is an obligation to supply capital and becomes an owned investment only as it is funded, so two percentages are worth tracking: the funded share today and the share after every commitment is called.

Family circumstances move the answer. Portfolios differ by generation, risk appetite, the industry the money came from, family priorities and location. Some offices manage only real estate, and for them the live question is the mix inside property, since the total share is fixed at the whole.

What a given percentage contains depends on ownership form and capital position

Two offices can both report the same real estate share and hold very different claims. Property credit, preferred equity and common equity held as a limited partner interest sit at different points in the capital stack. Offices adjusting their real estate allocations use those positions to change the risk profile of the property sleeve.

A move from common equity to preferred or credit changes the claim and leaves the exposure inside the real estate category. Reporting policy can hold all of them in one category with separate subcategories.

Direct ownership is a different implementation task from a fund commitment. One entry route into direct investing is partnering with experienced investors or with other family offices. The partnership spreads the work. The family’s economic interest still enters its allocation calculation.

Monitoring is a separate question from allocation. Offices track real estate and private equity holdings as part of total portfolio oversight, though direct investments rarely need daily attention. A holding that needs little attention still counts in the percentage when the next commitment is considered.

Families that can afford to grow their capital may use alternatives, private equity and hard assets to expand the family capital base. How much of that the allocation can carry depends on the distributions and cash reserves the same family must meet.

Worked example: a hypothetical $200 million family portfolio with a 30% real estate ceiling

This illustrative example compares a base case and a stressed case on the same basis. Starting capital, property values and the cash used for funding are identical in both. Only the value of securities differs. The policy ceiling is 30% of total equity, and the family requires a cash reserve of $9 million.

Starting position. Direct property is worth $60 million with $20 million of debt, so direct property equity is $60 million minus $20 million, or $40 million. Real estate fund interests of $10 million bring funded real estate equity to $40 million plus $10 million, or $50 million. Other assets are $100 million of securities, $30 million of operating business equity and $20 million of cash, a total of $150 million. Total equity is $50 million plus $150 million, or $200 million. The real estate allocation is $50 million divided by $200 million times 100, or 25%.

The gross numerator trap. Using gross property value gives $60 million plus $10 million, or $70 million. Divided by $200 million, that reads as 35%. The gap against the correct 25% is 10 percentage points, produced entirely by counting debt-financed property against a denominator of family equity.

Funding. Existing unfunded commitments are $8 million and a proposed commitment adds $6 million, so total calls are $8 million plus $6 million, or $14 million, all paid from cash. Funded real estate equity becomes $50 million plus $14 million, or $64 million. Cash falls to $20 million minus $14 million, or $6 million. Total equity is unchanged at $200 million minus $14 million plus $14 million, or $200 million, because cash converted into investments.

Base case. The allocation after funding is $64 million divided by $200 million times 100, or 32%. A 30% ceiling on $200 million is 30 divided by 100 times $200 million, or $60 million. Funded exposure exceeds it by $64 million minus $60 million, or $4 million, which is 32% minus 30%, or 2 percentage points.

Stressed case. Securities fall by $40 million, to $100 million minus $40 million, or $60 million. Other assets become $150 million minus $40 million, or $110 million, and total equity becomes $50 million plus $110 million, or $160 million. Before any new funding, the allocation is $50 million divided by $160 million times 100, or 31.25%. The family is already above its ceiling with no decision made.

After the same $14 million of calls, the stressed allocation is $64 million divided by $160 million times 100, or 40%. The ceiling in dollars is 30 divided by 100 times $160 million, or $48 million. Exposure exceeds it by $64 million minus $48 million, or $16 million, which is 40% minus 30%, or 10 percentage points.

Property funding was identical in both cases and the denominator moved. The breach grew from 2 points to 10 points.

The reserve test gives the same answer in both cases. Cash after funding is $6 million against a $9 million requirement, a shortfall of $9 million minus $6 million, or $3 million. An exception that permits the higher allocation settles only the allocation question. The cash gap remains.

Mistakes in reading and setting a real estate allocation

Treating a published average as a target confuses a description of a surveyed group with a family’s own policy. An average carries no delegation of authority and no information about the reporting perimeter behind it. Subtracting one reported average from another, such as 14.4% from 17%, measures a change in nobody, because the populations and reporting periods differ.

Comparing a direct ownership share of 22.5% with a total real estate share of 14.4% shows why definitions matter. On one portfolio a narrower category cannot exceed a broader one, so the two figures must come from different populations and denominators. Any comparison between them is arithmetic on unlike things.

Mixing gross property value with net equity puts debt-financed property on one side of the ratio only. In the example above it turns a 25% allocation into a reported 35% with no change in what the family owns. A consistent equity ratio deducts property debt in the numerator and uses net equity in the denominator, and a gross exposure measure needs its own gross denominator.

Adding unfunded commitments straight into current assets treats an obligation as an owned asset. Ignoring them leaves future cash calls outside the approval analysis. The correct record carries a funded percentage and a post-funding percentage, and the second one shows the cash left against the reserve.

Measuring the allocation only at purchase misses denominator drift. In the stressed case above, a $40 million fall in securities lifted the allocation from 25% to 31.25% before a single dollar was called. A ceiling tested only when a deal closes will be breached by market moves that no committee voted on.

Treating a deal approval as an allocation approval leaves the record ambiguous. A committee vote on a property authorizes the transaction. If funded exposure plus remaining commitments pass the policy band, the family’s policy may call for separate allocation approval and a record of which authority was used.

Checklist questions for testing a family office real estate allocation

Does the percentage cover managed investments or all family wealth, and does a reconciliation identify what each perimeter leaves out?

Are numerator and denominator on the same ownership basis, with property debt and partial interests reflected in the equity calculation?

Does a reconciliation identify whether an operating business valuation already includes property counted elsewhere?

Which direct holdings, fund interests, preferred equity and property credit sit inside the real estate category used for benchmark comparisons?

What are the allocation and remaining cash if every commitment is funded under the stated funding assumption?

Does cash after funding cover the reserve requirement independently of permission to hold the resulting allocation?

Who can approve a transaction and authorize an exception to the ceiling, and does the governing policy require separate approvals?

How far would a fall in other assets move the percentage if property values stayed constant?
