What Is a Capital Call in a Real Estate Syndication?

A capital call is a formal request from the sponsor of a syndication for investors to contribute additional money to the deal after the initial raise. Whether you have to pay depends entirely on the operating agreement. Some syndications make calls voluntary, and investors who skip them may be diluted or lose some rights.

If you are the sponsor, we built DoorRaise to set up the raise and the paperwork, and you and your attorney set the capital call terms.

This explainer belongs to our complete guide to real estate syndication. We stay on one question: what is a capital call, and how do you protect yourself from a bad one?

Why would a sponsor make a capital call?

A sponsor makes a capital call when the property needs more cash than the deal has on hand and borrowing more is not an option or is too expensive. The reasons are usually mundane. They are also the reasons a careful vetting process tries to test.

Common triggers include:

  • Renovations cost more than planned.
  • Occupancy or rents fall short and the property cannot cover its debt payments.
  • A loan requires a paydown to refinance or extend.
  • Major repairs, or taxes and insurance, rise faster than the budget assumed.
  • A lender requires a bigger reserve.

A capital call is not always a sign of failure, but it can be. The question to ask is whether the sponsor funded adequate reserves up front and what the underwriting assumed. See our multifamily underwriting basics for how a downside case should look.

Capital calls are not the same as a second raise

Some deals plan a follow-on raise as part of the business plan, such as a phase two renovation. That may be a new offer of securities, with its own disclosure and filing questions. A rescue capital call from existing members is often handled under the operating agreement instead, but whether it is a new sale of securities is a legal question for your attorney.

Where it is a new offer, the securities rules apply again. For a 506(b) sale to non-accredited purchasers, Rule 502(b) requires specified information to be furnished a reasonable time before sale, and a new sale can raise Form D questions (see Form D filing). Your attorney decides which one you have.

Mandatory or voluntary: which is it?

Mandatory means you are contractually bound to fund, up to whatever the agreement says. Voluntary means you may choose. The wording in the operating agreement controls, so read the capital contributions section before you invest, not after the notice arrives.

Topic Mandatory Voluntary
Must you fund? Yes, under the agreement No
Typical consequence of not funding Penalties, dilution, or loss of part of your interest Dilution of your ownership share
Loss exposure Can exceed the original investment, up to what you agreed to fund Generally limited to the original investment
Who decides Often the manager, sometimes with an investor vote Usually the manager

Some offering documents say that investors have no obligation to contribute more than their original investment. Others include a mandatory call up to a stated cap. Look for the exact wording, not the summary in the pitch deck.

Key terms to find

  1. Who can issue a call (manager alone, or with a vote).
  2. Any cap on mandatory contributions, in dollars or as a percentage of your investment.
  3. Notice period, often measured in days.
  4. Whether the sponsor must contribute too, and on the same terms.
  5. What happens on default, in detail.

What happens if you do not fund?

The agreement decides, and the range is wide. The outcomes below are ones commonly described in operating agreements. Not every deal uses all of them.

Dilution

Other members, often including the sponsor, fund the shortfall and receive a larger share of the deal. Your percentage drops. Some agreements dilute at par, so new money is simply added to the base. Others dilute at a penalty, so new money counts for more than a dollar.

Member loans

Some agreements let the others lend the missing money to the entity at a stated interest rate, repaid before distributions to equity. Your share does not shrink, but the loan sits ahead of you and its interest is a drag on cash flow.

Penalties and forfeiture

The agreement may reduce your preferred return, move your distributions to the funding members, or forfeit a portion of your interest. Whether a given penalty can be enforced may depend on state law and on how the document is written, so ask your attorney.

Forced sale

In extreme cases, an unfunded shortfall can force a sale or a lender action. This is the outcome both sides want to avoid, and it is the reason to read the default section closely.

Worked example: what dilution can look like

This is an illustrative example, not a projection. A deal raised $1,000,000 of equity and you own $100,000 of it, which is 10%. The property needs $200,000 of additional cash. You could fund your 10% share, which is $20,000.

Suppose you choose not to fund. Here are the outcomes, depending on what the agreement says.

Outcome What happens Your result
You fund your share You contribute $20,000 Still 10% of a $1,200,000 base
Dilution at par Others fund the $200,000, counted dollar for dollar $100,000 / $1,200,000 = 8.33%
Dilution at 150% Others fund $200,000, credited as $300,000 $100,000 / $1,300,000 = 7.69%
Member loan at 12% Others lend $200,000, repaid ahead of equity Still 10%, but $24,000 a year of interest accrues on the loan

Under the first row, your stake stays at 10% of the larger base and you have put in $120,000 in total. Under par dilution, you keep your $100,000 but your slice falls from 10% to about 8.3% of everything, including future profit. Under penalty dilution the slice falls further, to about 7.7%. Under the member loan, your slice does not move, but 12% interest on $200,000 is $24,000 a year that comes off the top before equity is paid.

The numbers are made up to show the mechanics. The real terms are in your agreement, and some structures use different formulas, such as dilution based on current value instead of cost.

How should investors prepare?

The best preparation is to know before you wire the money whether calls are possible and what they could cost. Then keep enough cash outside the deal that a call does not force a hard choice.

  1. Keep liquid cash outside the investment. A call can arrive with a short notice window.
  2. Ask what reserves the deal holds and how they were sized.
  3. Ask how often the sponsor has made capital calls on past deals, and why.
  4. Check the notice period and the default terms.
  5. Ask whether the sponsor's own money is subject to the same call.

What about taxes?

Capital contributions are generally not deductible. They generally increase your tax basis in the partnership, and basis limits how much of an allocated loss you can deduct. The IRS describes basis and loss limits, including at-risk and passive activity rules, in the Schedule K-1 (Form 1065) instructions. The partnership itself files a return on Form 1065.

How a member loan or a dilution event is treated for tax purposes is a CPA question. Do not assume.

Our take

Our take: the best protection against a capital call is the one built in at the start. Reserves sized for a bad year, a conservative loan and honest underwriting do more for investors than any default clause. If a sponsor's plan only works if nothing goes wrong, assume a call is possible.

For sponsors, we think the kindest call term is a clear one. Say whether calls are voluntary, how much notice investors get, and what happens if they decline. Surprises create disputes, and a call is stressful enough without a fight over the document.

Trade-offs and who this is not for

Voluntary calls are friendlier to investors but harder on the sponsor, who may have to find the money somewhere else. Mandatory calls give the sponsor more certainty and put real risk on investors. Neither is right for every deal.

A mandatory call is not for investors who cannot afford to put in more. If you are stretching to make the first investment, either pick a deal with no mandatory calls or invest less. Our guide to how much to invest covers sizing.

Finally, this article is not a legal opinion on any agreement. A penalty clause that looks harsh may be unenforceable, or enforceable. That depends on the document and your state.

How DoorRaise fits in

Capital call terms are set in the operating agreement by you and your attorney, and we do not recommend terms. DoorRaise helps sponsors raise equity for apartment buildings with 5+ units under Rule 506(b) or 506(c). We are software, legal document preparation, escrow coordination and verification services, not a law firm, broker-dealer, investment adviser or funding portal, and we never hold investor money.

We charge 0% of the raise or profits, with three flat fees. At setup, $500 forms the deal's LLC (including the registered agent), prepares investor documents from attorney-approved templates, opens an escrow account in the deal's name and runs accreditation checks on every investor. At closing, $5,000 is paid from the funds raised, only if the deal closes, and covers attorney review of the offering documents and the Form D filing. After closing, $3,500 a year is paid from the property's income and covers bookkeeping, the tax return and K-1s, and investor updates. State filing fees are included in the $5,000 closing fee.

FAQ

Can a sponsor force me to pay a capital call?

Only if the agreement says so and you signed it. Read the capital contributions and default sections before you invest.

Is a capital call a bad sign?

Not always, but it deserves an explanation. Ask what changed from the plan, what the sponsor is contributing and whether reserves were used first.

Is a capital call the same as a distribution?

No. A distribution sends money to you. A capital call asks for money from you.

How much notice do I get for a capital call?

It depends on the operating agreement. Some give a few weeks and some give less. Check the notice period before you invest and make sure you can fund in that time.

Can I sell my interest instead of funding a call?

Often there are transfer restrictions, and securities sold under Regulation D are generally restricted from resale. Rule 502(d) requires the issuer to take steps to make sure buyers are not underwriters, including a legend. Selling usually needs the manager's consent. Read the transfer section of the agreement.

Do capital calls affect my taxes?

They are not deductible. Contributions generally increase your basis in the partnership, which can matter for deducting losses later. Talk to a CPA about your situation.
