How Much GP Co-Investment Do Family Offices Expect from a Real Estate Sponsor Raising $20M in Equity?

For a $20M real estate equity raise, family offices generally expect the GP to contribute 5% to 10% of total LP equity, or $1M to $2M. The co-invest should be direct cash at risk from closing, because deferred fees, promote recycling, and deal-secured leverage do not provide the same alignment signal.

Family offices treat GP co-investment as an alignment filter, and they apply it before reviewing deal fundamentals. When a sponsor raises $20M in LP equity, the family office investment team wants to know one thing before opening the financial model: how much of the GP's own capital is at risk alongside theirs. The answer to that question determines whether the deal moves to diligence or stops at the first meeting.

This is a calibration guide for sponsors preparing for or actively negotiating with a family office LP on a $20M equity raise. It covers the co-invest percentage family offices treat as a credibility threshold at this raise level, how that percentage is calculated, what structures qualify, how deferred arrangements are evaluated, how co-invest position affects the promote conversation, and what to include in a co-invest disclosure package before the LP call.

Sponsors who want to understand how co-invest interacts with the broader LP/GP economics should also review how to calculate the right GP/LP split for your deal, which covers promote sizing and waterfall tier design in detail. This article focuses specifically on the co-invest threshold question at the $20M equity raise level.

Why Family Offices Screen on Co-Invest Before Deal Fundamentals

A family office writing a $20M equity check is underwriting the sponsor as much as the deal. The co-invest question comes first because it answers a structural concern that no financial model can resolve: if conditions deteriorate, does the GP have a financial reason to protect LP capital?

A sponsor with meaningful cash at risk has a direct economic incentive to manage the project with discipline. A sponsor with a nominal co-invest shifts downside risk to the LP while retaining upside through the promotion. Family offices have become more explicit about this distinction as deal-by-deal structures have replaced blind pool commitments across the lower-middle market. The core principle is straightforward: GP co-investment signals that the sponsor shares the LP's downside alongside the promote upside. 

Key point: Co-invest is an alignment signal. It tells the LP whether the GP's incentives are structurally aligned with LP capital from day one.

The Core Co-Invest Decisions Sponsors Must Address

What Percentage of GP Co-Invest Do Family Offices Expect at the $20M Raise Level?

At a $20M LP equity raise, the institutional reference range for GP co-invest sits between 5% and 10% of total LP equity, translating to $1M to $2M in absolute dollars.

The 5% floor is the baseline for most ground-up and value-add deals with a seasoned track record. The 10% threshold applies when execution risk is elevated: longer construction timelines, a first institutional raise, or a business plan dependent on lease-up performance.

How Co-Invest Is Calculated Against Total Project Cost vs LP Equity

Family offices calculate co-invest as a percentage of total LP equity, not total project cost. These are different numbers.

On a $20M LP equity raise with $40M in senior construction debt, total project cost is $60M or more. A 5% co-invest against total project cost is $3M. A 5% co-invest against LP equity is $1M. Family offices use LP equity as the denominator because it represents the capital they are putting at risk.

Before any LP conversation, sponsors should confirm:

1. Total LP equity being raised
2. GP co-invest as both a dollar amount and a percentage of that equity
3. The source of that capital, documented and ready to share

What Qualifies as GP Co-Invest and What Family Offices Discount

Structures family offices accept:

• Direct cash from the GP's personal or entity accounts
• A loan secured by assets held outside the subject deal, with full disclosure

Structures family offices discount or reject:

• Deferred acquisition or management fees credited as equity
• Promoted interest from a prior deal recycled into the current co-invest
• Leverage secured by the subject deal itself

Institutional allocators aligned with ILPA standards require the co-invest to be traceable to direct cash equity, held in a segregated account or entity, and at risk from the date of capital contribution.

How Deferred Co-Invest or GP Fee Credits Are Evaluated

Deferred co-invest arrangements are evaluated skeptically because the GP's capital is not at risk during the construction and stabilization period, when execution risk is highest.

Some family offices accept a hybrid structure where a portion is funded at close and the remainder is funded from a documented source within a defined period. The funded-at-close portion must meet the 5% floor on its own. A deferred commitment that brings the total to 10% over 18 months does not satisfy the alignment standard for the period before funding is complete.

GP fee credits are treated as a zero-alignment contribution. The GP has reduced a fee obligation with no capital placed at risk.

How Co-Invest Interacts with the Promote and Waterfall Structure

GP co-invest and promote are negotiated together. A sponsor seeking a 20% promote with a 5% co-invest maintains a defensible position. Conversely, a 25% promote with a 3% co-invest creates friction because the upside claim is disproportionate to the downside exposure.

A sponsor who increases co-invest from 5% to 10% gains leverage to defend or expand the promote. A sponsor who falls below the threshold weakens their position on every economic term that follows.

How to Present Co-Invest Position When It Falls Below the Expected Threshold

Sponsors below the 5% threshold have two options: increase it before the LP call, or present a documented explanation before the LP asks.

If the co-invest cannot be increased, address it proactively in the term sheet or executive summary. A reactive explanation after an LP question carries less weight than a pre-emptive disclosure with a clear rationale.

Acceptable explanations family offices will evaluate:

• Significant capital committed across multiple active co-invest positions, with aggregate exposure documented
• A personal guarantee on senior debt that represents meaningful downside exposure
• A co-invest escrow funded at close with a documented capital source and clear timeline

Explanations family offices reject:

• "We will fund the co-invest from the promote on this deal"
• "We are contributing our time and expertise as our equity"

Sponsors in a below-threshold position should also review how family offices assess sponsor liquidity before outreach, as the liquidity documentation requirements are closely connected to the co-invest conversation.

What a Co-Invest Disclosure Package Should Include Before the LP Call

A co-invest disclosure package is a set of answers that must be ready before any family office call, organized so the LP's investment team can verify the position without follow-up requests. The SEC's disclosure guidance for real estate limited partnership offerings establishes the standard for what constitutes a complete and balanced disclosure to prospective investors.

The six elements a co-invest disclosure package must include:

1. Dollar amount and percentage of LP equity. State both figures. A percentage without a dollar amount is incomplete. A dollar amount without the calculation basis is ambiguous.
2. Source documentation. Identify the account or entity the capital is coming from. Personal accounts, entity accounts, and external loans all require different supporting documents.
3. Funding date. Confirm when the co-invest is contributed to the deal entity. At-close funding is the institutional standard.
4. Treatment in a downside scenario. Explain how the GP's co-invest is treated if the deal requires additional capital or fails to return LP principal. This is the question most sponsors arrive unprepared to answer.
5. Relationship to fee structure. Disclose whether any portion of the co-invest is funded by fee credits, and if so, clarify what portion is direct cash equity.
6. Aggregate co-invest exposure. List the GP's total co-invest commitments across all active deals. Family offices want to know the sponsor is not over-extended.

The co-invest disclosure package is one component of a broader diligence sequence. What institutional LPs audit before the first call covers the full review from track record to governance.

IRC Partners works with real estate sponsors preparing for institutional LP outreach on raises from $5M to $250M. If your co-invest position needs to be structured, documented, or presented before a family office conversation, that is the work that happens before the LP sees the deal.

Frequently Asked Questions

What is the minimum GP co-invest a family office will accept at the $20M equity raise level?

The institutional floor for most family offices at the $20M equity raise level is 5% of total LP equity, or $1M in absolute dollars. Deals with elevated execution risk, such as ground-up construction or a first institutional raise, typically require 7% to 10%. Sponsors below 5% should expect alignment questions before the investment committee stage.

Does GP co-invest get calculated against total project cost or total LP equity?

Family offices calculate co-invest as a percentage of total LP equity, not total project cost. On a $20M equity raise with $40M in senior debt, total project cost may exceed $60M. A 5% co-invest against LP equity is $1M. Against total project cost, it would be $3M or more. Always state both the dollar amount and the LP equity percentage when presenting co-invest position.

Do deferred acquisition fees count as GP co-invest?

Deferred acquisition fees fall outside the co-invest standard institutional allocators apply. The GP carries zero cash exposure. If the deal loses value, the sponsor absorbs a fee credit reduction with no real capital at stake. ILPA-aligned allocators require the co-invest to be funded with direct cash equity and at risk from the date of contribution.

Can a GP fund their co-invest with a loan?

A loan secured by assets held outside the subject deal is generally acceptable with full disclosure. A loan secured by the subject deal itself is rejected by most family offices because the GP's downside exposure depends entirely on the deal's own performance.

How does GP co-invest affect the promote negotiation?

Co-invest and promote are negotiated together. A 20% promote with a 5% co-invest is defensible. A 25% promote with a 3% co-invest is difficult to defend because the upside claim is disproportionate to the downside exposure. Increasing co-invest from 5% to 10% is often the fastest way to protect or expand promote position while keeping LP headline economics unchanged.

What happens if the GP co-invest is funded in stages rather than at close?

Staged funding is evaluated against the 5% floor on the at-close portion alone. A deferred commitment that brings the total to 10% over 18 months leaves the GP's capital absent during construction and stabilization, which is when execution risk is highest. Family offices require the GP's capital to be present and at risk from the contribution date forward.

What documents should a sponsor prepare to verify co-invest before the LP call?

Sponsors should prepare a capital contribution agreement or equivalent document showing the dollar amount, funding source, and contribution date. If the co-invest is funded by an external loan, the loan documentation and collateral description should be ready. A personal financial statement or entity balance sheet showing the capital source outside the deal is also standard. Family offices will ask for these within the first two diligence sessions.
