A single apartment acquisition can be financed a dozen different ways, and the structure decides who profits. Sponsors who understand multifamily financing early are already locking in senior debt while others are still comparing headline rates.
The capital stack is the deal structure established before a single unit is renovated or a lease is signed. The loan type and the equity layered above it decide what sponsors and investors keep at exit.
What Is the Multifamily Capital Stack?
The capital stack is the tiered structure of debt and equity used to finance an apartment acquisition, organized strictly by risk profile and repayment priority. Senior debt sits at the base with the lowest risk while common equity sits at the top with the highest risk and uncapped potential upside.
This capital hierarchy operates on two governing principles:
- Distributions flow from the bottom up: The most senior, lowest-risk capital receives scheduled debt service before subordinate debt or equity partners receive any cash flow.
- Losses flow from the top down: If operating performance declines or market values contract, common equity absorbs the initial losses before subordinate capital or senior lenders experience principal impairment.
Alliance Consolidated Group of Companies stress-tests every prospective acquisition against these waterfall dynamics to evaluate downside protection before terms are finalized.
Worked Example: A $20 Million Acquisition Sold in Distress for $15 Million
Senior debt is fully insulated due to its first-lien priority. Subordinate capital absorbs losses in reverse order of priority, which is why upper-tier capital demands higher target yields to offset potential loss exposure.
What Are the Common Types of Multifamily Loans
Six loan products cover most of the multifamily debt market, and each one fits a different stage of a property's business plan. Picking the wrong one is one of the fastest ways to lose leverage or blow your closing timeline, so it helps to know what you're choosing between before you're under contract.
Agency Loans (Fannie Mae & Freddie Mac)
Agency debt through Fannie Mae (Delegated Underwriting and Servicing, or DUS, program) and Freddie Mac (Optigo program) represents the primary benchmark for stabilized apartment assets.
Conventional executions frequently support leverage up to 80% LTV and minimum debt service coverage ratios (DSCRs) starting around 1.25x, though exact requirements vary by market tier, affordability classification and specific program guidelines.
These loans provide nonrecourse execution with standard carve-outs for "bad acts". Key underwriting baselines typically include:
- Leverage sizing, typically up to 80% LTV (tiered by market and asset quality).
- Fully amortizing terms up to 30 years, often with structured interest-only periods.
- Stabilized physical occupancy (typically 90%+ sustained for 90 consecutive days prior to funding).
- Prepayment structures governed by yield maintenance or structured declining step-down schedules.
This kind of agency financing is well-suited to core and core-plus holdings with a medium- to long-term horizon. Prepayment runs through yield maintenance or step-down schedules, so exit timing matters here as much as the rate you locked at entry.
Commercial Bank Loans (Balance Sheet Lenders)
Regional and national banks hold apartment loans directly on their balance sheets rather than selling them off, which changes how they underwrite them. Because the bank is keeping the risk, this relationship-based lending usually comes with full or partial recourse guarantees from sponsors.
Leverage caps are lower here too, generally 60% to 70% LTV, paired with three- to five-year terms and 25-year amortization. In exchange for that lower leverage, banks tend to move faster and charge lower closing costs, which can matter more than rate on a tight timeline.
If you already have a banking relationship or you're working a smaller deal that needs flexible structuring outside a standardized agency box, this is usually where that flexibility lives.
CMBS Loans
CMBS loans get pooled with other commercial mortgages and sold as securities to bond investors, which is what separates them from a straightforward bank or agency loan. The trade-off for that access shows up clearly once you line up the terms:
That combination opens the door for borrowers who might not clear agency thresholds, but it comes with less flexibility once the loan is in place.
Multifamily Bridge Loans
Bridge loans fund transitional properties for one to three years at floating rates tied to the SOFR, built for exactly the gap agency and bank loans won't touch. The structure is built around where the property is headed and not where it stands today:
Sponsors use this multifamily debt specifically to acquire and reposition assets that aren't stabilized enough yet for permanent financing, with the refinance built into the plan from closing.
Government-Insured Debt (HUD / FHA)
HUD and FHA programs, including HUD 223(f), insure long-term, nonrecourse, fully amortizing loans for multifamily acquisitions and refinances. If you're structuring for the long haul, this is where the terms get hard to beat.
Terms stretch up to 35 years fixed, with leverage reaching 85% to 90% LTV and DSCR minimums as low as 1.11x for affordable properties. Rates here tend to run below the rest of the market, which is the trade-off working in your favor.
The cost is time, not money. HUD approval typically takes six to 12 months given the environmental, architectural and capital needs reviews required before closing, so this path only works if your timeline can absorb it.
Ground-Up Construction Financing
Construction loans fund land acquisition and vertical development, structured as short-term, interest-only debt over roughly two to three years. This is where multifamily financing shifts from buying an existing asset to building one from the ground up. Before a lender funds that first draw, they're generally looking for:
- LTCunderwriting rather than LTV
- Meaningful sponsor equity in the deal
- Completion guarantees backing the project
- A developer track record on comparable projects
From there, you have two paths. Some sponsors use single-close construction-to-permanent execution, like HUD 221(d)(4), to lock in a 40-year fixed rate before construction even starts. Others close short-term construction debt first and refinance into permanent agency financing once the property stabilizes.
The right multifamily financing choice always traces back to where your property sits in its business plan, and the multifamily leverage of each loan type only matters once you know which stage you're financing.
What Determines Multifamily Loan Rates and Pricing?
Commercial multifamily interest rates are calculated by adding a lender credit spread to an underlying market benchmark rather than quoting a static rate. Underwriters evaluate pricing across eight core market and asset variables:
Evaluating these pricing components across the capital structure allows sponsors to lower their blended cost of capital across the portfolio. That pricing efficiency directly widens the spread between net operating income (NOI) and debt service, increasing the cash flow available to redeploy.
How To Match the Right Loan and Capital Stack to Your Deal
Your property's stage in its business plan narrows the field before rate shopping even starts. Skipping this step is how sponsors end up forcing a stabilized loan onto a transitional asset or the reverse, and both mistakes get expensive fast:
- Value-add acquisitions: Bridge debt paired with soft preferred equity supports capital improvements during lease-up.
- Stabilized holdings: Agency or HUD financing locks in long-term fixed rates.
- Development projects: Construction debt refinanced into agency permanent financing upon physical stabilization.
- Refinancings: Sized against trailing 12-month NOI to maximize return of capital.
Sponsors structure their debt around asset timelines to maintain operational flexibility.
How Much Can You Borrow on a Multifamily Property?
Commercial underwriters size loan proceeds by running three sizing tests simultaneously: LTV, DSCR and debt yield. Total senior loan proceeds are capped by whichever calculation yields the lowest dollar amount.
Consider a $10,000,000 acquisition with an in-place NOI of $650,000, evaluated at a 6.50% interest rate with a 30-year amortization schedule (7.5848% loan constant):
The cash-flow constraint limits the senior loan to $6,855,817 under the 1.25x DSCR test, leaving a remaining $3,144,183 capital requirement to complete the acquisition. While sponsors frequently evaluate subordinate capital to fill this gap, agency lenders maintain strict guidelines regarding acceptable preferred-equity structures and control rights.
Sponsors must confirm program eligibility with their agency lender before integrating subordinate capital into the capital stack.
Why Sophisticated Investors Focus on Capital Structure
Your capital stack isn't just how you fund a deal; it's the lever that shapes your quarterly cash flow, your reinvestment capacity, and how your portfolio grows over time. Sophisticated investors treat it that way from day one, not as an afterthought once the loan is signed:
- Cash flow: Lower-cost senior debt widens the spread between NOI and debt service, which increases what you distribute
- Reinvestment: Equity preserved through disciplined leverage funds your next acquisition sooner
- Capital efficiency: Blending senior debt with the right mix of preferred and common equity lowers your overall cost of capital across the deal
- Compounding: Each cycle of disciplined structuring builds toward a stronger equity multiple across your portfolio, not just the single asset
That compounding effect is exactly what shows up over time when the structure stays disciplined deal after deal. Alliance CGC's own track record, a 28% historical internal rate of return (IRR) and a 2.5x average equity multiple across more than $500 million in commercial real estate (CRE) assets, reflects what that discipline builds into across multiple cycles.
Turn Your Capital Stack Into a Competitive Advantage
Every multifamily financing decision made before closing shows up in the returns after closing, and by then there is no renegotiating the stack. Sponsors who structure the capital stack early keep more of the upside when the deal exits while everyone else finds out what they gave away only after the sale.
At Alliance CGC, every acquisition runs through this same discipline: Matching the right loan and capital stack to the property's business plan before terms get finalized, not after.
If you're weighing how to structure financing for your next multifamily acquisition, schedule a consultation with Alliance CGC to discuss current opportunities and build a capital strategy around your goals.
Multifamily Financing Frequently Asked Questions
What does multifamily financing typically cost?
Senior debt in multifamily financing generally prices between 5.5% and 7.5% while subordinate layers such as mezzanine debt or preferred equity typically range from 8% to 15% depending on structure and risk position. Blended cost of capital depends on how much of the stack sits in each layer. Sponsors who negotiate the subordinate layers as carefully as the senior loan protect more of their equity multiple at exit.
What is the difference between mezzanine debt and preferred equity?
Mezzanine debt is a loan secured by a pledge of equity ownership in the property entity and typically requires an Intercreditor Agreement with the senior lender. Preferred equity is an ownership interest inside the same entity, with priority distributions ahead of common equity but no separate lien. Fannie Mae and Freddie Mac often restrict mezzanine debt, which is one reason preferred equity has become the more common gap-filler in agency-financed deals.
How does multifamily leverage affect returns?
Higher multifamily leverage reduces the equity a sponsor needs at closing, which can increase the equity multiple and IRR if the property performs. It also increases the debt service the property must cover every month, so the DSCR cushion shrinks as leverage rises. Sponsors weigh that trade-off deal by deal, matching leverage to how much cash-flow volatility the business plan can absorb.
Which multifamily loan type closes the fastest?
Bank balance sheet loans and bridge debt typically close fastest, often in 30 to 45 days because underwriting stays with a single capital source. Agency and CMBS loans usually take 45 to 60 days. HUD and FHA financing takes the longest, often six to 12 months, due to extensive environmental and capital needs reviews. Sponsors on a tight closing timeline should rule out HUD early rather than late.
