What Is a Multifamily Syndication? Structure and Risks

A multifamily syndication is a real estate syndication that buys an apartment community, usually 5 or more units. A sponsor finds and runs the property, and passive investors supply most of the equity in exchange for a share of cash flow and sale proceeds. The deal is held in a single-purpose company, and the investment is illiquid.

If you are the sponsor, we built DoorRaise to run the equity raise for exactly this kind of deal. This post covers what is specific to apartments. For the general mechanics, read our pillar guide to real estate syndication.

Why do multifamily syndications focus on 5+ units?

Lenders commonly treat buildings with five or more units as multifamily or commercial real estate rather than one-to-four-unit residential, which changes how they are financed and valued. Fannie Mae's conventional multifamily term sheet, for example, covers properties with a minimum of five units. That shift is the reason syndication exists for apartments and why sponsors build deals around larger buildings.

Financing changes at five units

Loans on one to four units are generally residential mortgages underwritten mainly on the buyer's income and credit. Larger apartment loans are commonly underwritten on the property's income, with the lender looking at net operating income and the debt service coverage ratio (that Fannie Mae term sheet lists a minimum DSCR of 1.25x for its program). Lenders still ask for sponsor experience and liquidity, and may ask for a guaranty. Terms vary by lender, loan type and year, so check current requirements with a lender or broker before building a model.

Valuation changes at five units

Small residential properties are often priced by comparable sales. Larger apartments are commonly priced by income. A simple version: value equals net operating income divided by the cap rate. That means each dollar of NOI added through higher rents or lower costs can add several dollars of value. It also means a bad assumption does the reverse. See multifamily underwriting basics.

Size creates the need for outside equity

A 100-unit building can cost eight figures. Few individuals write that check, so the sponsor combines a loan with investor equity. A typical shape is below, and every number is illustrative.

Piece	Illustrative amount	Share of total
Loan	$7,000,000	70%
Investor and sponsor equity	$3,000,000	30%
Total capitalization	$10,000,000	100%

The layers of money are called the capital stack. See the real estate capital stack.

How is a multifamily syndication structured?

A multifamily syndication is structured as one company that owns one building, with a sponsor managing it and investors holding passive membership interests. The legal pieces are the same across most deals, and each does a different job.

The sponsor forms an LLC that owns the property. This keeps one asset in one entity. See real estate SPV explained.
The sponsor contracts to buy the building and arranges the loan.
Investors subscribe. They sign a subscription agreement and buy membership interests, after reading a private placement memorandum.
The operating agreement sets the rules for voting, fees, distributions and exit. See syndication operating agreement.
Cash flow is paid under a waterfall, often with a preferred return first and the sponsor's promote after. See waterfall and promote.
The property is sold or refinanced and the proceeds are distributed.

Under Rule 506, interests are offered in a private placement and are restricted securities. The resale conditions in Rule 502(d) require the issuer to tell buyers the securities are unregistered and restricted. That is a legal reason, beyond the business reason, that you cannot expect to sell your interest quickly.

What are the common business plans?

Multifamily deals fall into three business plans, and the plan tells you where the risk sits. Ask which one a sponsor is running before looking at any projected return.

Plan	What happens	Where risk sits
Stabilized (core)	Buy a well-leased building, hold for income	Overpaying, rising expenses, refinancing
Value-add	Renovate units or improve operations to raise rents	Renovation cost, lease-up speed, floating debt
Development	Build a new property	Construction cost, delays, lease-up, financing

Why value-add is so common

Value-add is a common plan because it ties the equity story to something the sponsor controls. It is also where many first-time investors get hurt, because it depends on spending money on renovations and then getting tenants to pay more.

An illustrative value-add example

Suppose a sponsor buys the 100-unit building above for $10,000,000, which is $100,000 a unit. The plan is to renovate 40 units at $12,000 each, a budget of $480,000. After renovation, each of those units rents for $150 a month more. The extra rent is 40 units x $150 x 12 months = $72,000 a year. To keep the example simple, it ignores vacancy and extra costs.

The renovation earns $72,000 on $480,000 spent, which is 15% a year. Value depends on the cap rate the market applies. At 6.0%, $72,000 of added NOI supports $1,200,000 of value. At 5.5%, it supports about $1,309,000. At 7.0%, about $1,029,000. The same renovation creates very different value depending on the market at the time of sale.

Now suppose costs run 20% over, to $576,000. The same $72,000 now earns 12.5% on cost. A small overrun is survivable. A large overrun plus slower leasing plus a higher cap rate is how value-add deals disappoint. Nothing here is a projection. It shows why you test the plan under stress.

Who can invest in a multifamily syndication?

Eligibility depends on the securities exemption the sponsor uses. Most multifamily syndications are offered under Rule 506(b) or 506(c).

Under Rule 506, a 506(b) deal can include up to 35 non-accredited purchasers in any 90 days, but each must have enough knowledge and experience to evaluate the investment, and the sponsor must provide extra disclosure. A 506(c) deal allows general solicitation but requires every purchaser to be accredited and verified.

The accredited investor definition in Rule 501(a) includes individuals with a net worth over $1,000,000 excluding the primary residence, or income over $200,000 individually or $300,000 jointly in each of the two most recent years. Many sponsors accept only accredited investors even when 506(b) allows others. See investing without being accredited and how much to invest.

States also receive notice filings. Because Rule 506 securities are "covered securities" under 15 U.S.C. 77r, states can require notice filings and fees but generally cannot require registration of the offering itself. State antifraud authority remains.

What are the main risks?

The main risks are leverage, sponsor execution, market conditions, illiquidity and the possibility of more capital calls. Any of them can hurt returns, and none is removed by a good pitch.

Leverage. Debt magnifies gains and losses. If income falls short, the lender is paid before equity.
Sponsor risk. Outcomes depend on the sponsor's skill, honesty and staying power. See how to vet a syndication.
Interest-rate and refinancing risk. Floating-rate loans can raise payments. Loans that mature before the plan finishes may need refinancing at worse terms.
Market risk. Rents, vacancy, insurance and property taxes can move against the plan.
Illiquidity. There is no public market for your interest, and the operating agreement usually limits transfers.
Capital calls. Some deals can ask for more money. See what is a capital call.

Our take

Our take: the plan matters less than whether the sponsor has stress-tested it. We would rather see a modest value-add plan with a reserve and fixed debt than an ambitious plan that only works if everything goes right.

We also think investors should ask for the numbers in writing before the call: the rent roll, the trailing 12-month statement, the loan terms and the renovation budget. A sponsor who shares them readily is giving you information. One who avoids them is giving you information too.

Trade-offs and who this is not for

Multifamily syndication trades control and liquidity for access to larger assets and professional management. It suits a narrow set of investors and sponsors.

Investors who may need the money back. Hold periods are set in the offering documents and are often several years, and early exits are generally not allowed.
Investors who want daily pricing. A publicly traded REIT trades on an exchange. Private deals do not. See syndication vs REIT.
Investors who dislike tax paperwork. Investors receive a Schedule K-1. The IRS Form 1065 instructions set a March 15 due date for calendar-year partnership returns and allow an extension on Form 7004, so a K-1 can arrive later than you expect. See K-1s in real estate syndication.
Sponsors without a team. A raise without an attorney, a property manager and a lender is a story, not a deal.
Sponsors who plan to market to strangers under 506(b). That route prohibits general solicitation. See what is general solicitation.

How DoorRaise fits in

DoorRaise is software, legal document preparation, escrow coordination and verification services for sponsors raising equity for apartment buildings with 5+ units, from people who already trust them, under Rule 506(b) or 506(c). We take 0% of the raise or profits, and we do not hold investor money. Funds go to an independent escrow agent named on each deal.

There are three flat fees. $500 at setup covers the deal's LLC and registered agent, investor documents from attorney-approved templates, an escrow account in the deal's name, the deal page, live call sign-up and accreditation checks on every investor. $5,000 at closing, paid from the funds raised and only if the deal closes, covers attorney review of the offering documents, checks on the sponsor, purchase contract, title and loan, the Form D filing and electronic signing, escrow paying the title company, and the investor portal and document vault. $3,500 a year while you own the property, paid from its income, covers bookkeeping, the tax return and K-1s for every investor, payouts and updates, and final tax forms at sale.

If the raise does not close, you never pay the closing or yearly fee and every investor gets money back from escrow. State filing fees are included in the $5,000 closing fee. DoorRaise does not recommend, rank or endorse any offering and is not a law firm, broker-dealer, investment adviser or funding portal. See pricing.

FAQ

Is multifamily syndication the same as apartment syndication?

In practice, yes. "Multifamily" is the industry term and "apartment" is how many people search for it. Both usually mean a building with five or more units.

How big is a typical multifamily syndication?

Sizes range widely, from small buildings to large communities. What matters more is whether the sponsor has operated something of similar size.

How long is my money tied up?

The hold period is stated in the offering documents and is often several years. The sponsor may sell sooner or later than planned, and investors generally cannot choose when to exit.

What is the difference between multifamily syndication and owning a rental property?

A syndication investor owns a small share of an LLC and has no control over daily decisions. A direct owner has control, liability and management duties. See syndication vs REIT vs owning.

Do I need to be accredited to invest?

Often, but not always. A 506(c) deal requires it. A 506(b) deal can accept a limited number of non-accredited investors who meet the knowledge and experience standard, though many sponsors choose to accept only accredited investors.

Is a multifamily syndication safe?

No investment is risk-free, and syndications can lose money. Evaluate the sponsor, the business plan and the debt, and read the offering documents with your own attorney or CPA.
