The Capital Stack: Every Way to Fund a Deal

Every deal — whether it is a single-family rental, a Main Street business, or a 50-unit apartment complex — is built on a capital stack: the ordered layering of every dollar that funds the acquisition. The stack orders sources from cheapest and most-controlled at the base to most expensive and least-controlled at the top. Think of it as the financing answer to the question every buyer eventually faces: where does the money come from?

The capital stack is not just theory for Wall Street analysts. It is the framework that tells you whether you bring cash, raise equity, borrow from a bank, tap a retirement account, or let the seller carry the note. And it is the framework that makes “no money down” possible — because no-money-down means none of your equity goes into the stack, not that the stack itself is empty. Every dollar still has to come from somewhere. The art is putting together sources that cost you nothing personally.

How the Stack Works

A capital stack has three layers, ordered from the base up:

1. Senior debt — the cheapest money, secured against the asset, paid first. Banks, credit unions, agency lenders. If the deal fails and the asset is sold, senior debt gets paid before anyone else sees a dollar. That seniority is why it costs the least: the lender takes the least risk.

2. Mezzanine / preferred equity — gap capital between senior debt and common equity. More expensive than senior debt (lender is subordinate), cheaper than selling common equity, often comes with warrants or an equity kicker.

3. Common equity — the owner’s capital, the sponsor’s syndicated raise, the joint venture partner’s cash. Equity absorbs the first loss and collects the last dollar of profit. It is the most expensive capital in the stack because it carries the most risk — and because it is the only layer that captures the upside.

The practical implication: the more equity you put in, the more control you keep and the less monthly debt service the deal carries. The more debt you layer on, the higher your return on equity — and the thinner your margin for error if vacancy hits or the market turns.

Below, every source of capital is catalogued across the three families that fund acquisitions: equity (I), institutional and conventional debt (II), and creative and structured finance (III). For each source you will find what it is, when it makes sense, and where to go deeper — either to an existing guide article or to a glossary definition.

I. Equity Capital

Equity sits at the bottom of the stack: it absorbs the first loss, collects the last dollar of profit, and — critically — it is not borrowed, so it carries no fixed repayment schedule. The more equity in a deal, the more stable the cashflow and the lower the risk of default. The cost of equity is dilution: you give up a piece of the future.

Cash & Owner Equity

Cash. The simplest source in the stack — your own savings, checking, or brokerage account. Cash closes deals fast and carries no strings, but it is also the most expensive capital in opportunity-cost terms. Deploy yours last, not first. A dollar you bring to closing is a dollar that cannot cover a roof replacement in month two.

Self-Directed IRA / 401(k). Retirement capital you direct into private investments — real estate, business equity, notes — rather than stocks and mutual funds. An SDIRA or Solo 401(k) can fund part or all of a down payment, but the account owns the investment, not you personally. All income and expenses must flow through the account, and you cannot self-deal (no buying a property from yourself, no living in an IRA-owned house, no paying yourself for repairs). The tradeoff is tax-advantaged compounding in exchange for compliance overhead. SDIRA custodians like Equity Trust, uDirect IRA, and Advanta IRA handle the paperwork; expect annual fees of $300-$2,000 depending on asset type and transaction volume.

Partner Capital. A business partner brings cash to close while you bring the deal, the operations, or the relationships. The split is negotiable — 50/50, 70/30, whatever reflects each party’s contribution — and must be documented in an operating agreement before money moves. Look for partners who complement your gaps, not mirror your strengths. A capital partner plus an operator is a natural pairing.

Family Office Capital. Single-family and multi-family offices managing concentrated wealth increasingly allocate to direct real estate and private business acquisition. Family offices can write larger checks than most individual investors (often $500k-$10M per deal), take a longer view, and value asset-backed yield over public-market correlation. They are relationship-driven and move slowly — expect a 6-12 month courtship before capital lands. Approach through introductions, not cold emails.

Private Capital

Private money fills the gap between what you have and what institutions will fund. It is sourced from individuals, not banks, and the terms are negotiated person-to-person.

Private Money Lenders (PML). Individuals who lend their own capital secured by real estate, typically at 8-12% interest with short terms of 6-24 months. Unlike hard money lenders — who are institutional and lend fund capital — PMLs are relationship-based: you are borrowing from a person who trusts you and your deal. The money is fast (close in days, not weeks) but expensive, making PMLs ideal for acquisition and rehab before a long-term refinance exit. Build a PML network before you need it: attend REIA meetings, bring deals that work on paper, and never miss a payment — a PML’s word-of-mouth reputation can open or close your access to capital in a market.

Friends & Family. The most accessible but highest-stakes source in the stack. Treat these arrangements with the same formality as any institutional debt: a written promissory note, a recorded mortgage or deed of trust, and a clear repayment schedule. The fallout from a blown family loan outlasts any deal. Structure it so they win whether the deal wins or not — a fixed-rate note with on-time payments is safer for a non-sophisticated lender than an equity participation they do not understand.

High-Net-Worth Investors. Accredited individuals — $200k+ annual income or $1M+ net worth excluding primary residence — seeking yield outside public markets. They typically want 8-12% on a secured note or a preferred return (6-8%) plus equity participation. The pitch: “Your capital is secured by real estate and you earn more than bonds pay, with less volatility than stocks, and you get a lien on the asset.” HNW investors are found through professional networks, industry conferences, and introductions, not mass marketing.

Angel Investors. Individuals who back acquisition entrepreneurs or early-stage operators in exchange for equity — typically 20-40% of the deal. In the acquisition context, angels often fund the search phase or the down payment. Angel capital is patient (they expect to wait 3-7 years for an exit) but dilutive: you are selling part of the future to fund the present. Angel groups and platforms like Searchfunder and Axial connect buyers with angel capital.

Pooled Capital

Pooled capital aggregates money from multiple investors into a single vehicle, letting you pursue deals larger than any one source could fund alone.

Create a Fund. Raising a dedicated vehicle — a real estate fund, a search fund, or a small acquisition fund — where limited partners (LPs) commit capital and you, as general partner (GP), deploy it. Funds give you committed dry powder and let you move fast on deals, but they require securities-law compliance (Regulation D, typically 506(b) or 506(c)), a track record, and an investor network that takes years to build. This is an advanced move for operators who have already closed several deals and can demonstrate consistent returns.

Syndication. Raising capital deal-by-deal from a group of passive investors rather than through a blind-pool fund. The syndicator (GP) finds, structures, and operates the deal; the limited partners fund it in exchange for a preferred return (typically 6-8%) and a split of the upside above that hurdle (often 70/30 LP/GP after return of capital). Syndication is the most common path to scaling beyond your own balance sheet because you raise only when you have a specific deal — no committed fund required, no ongoing LP reporting burden between deals. The catch: you are marketing securities, and you need a securities attorney to structure the offering documents correctly.

Joint Ventures. A partnership between two or more parties on a single deal, where each contributes something different: one brings capital, another brings operations, a third brings the deal flow, a fourth brings the credit or the guarantee. JVs are governed by a joint venture agreement that defines contributions, profit splits, decision rights, and exit mechanics. Less formal than a fund, more flexible than a syndication, and ideal when the parties have clearly complementary roles. The most common JV pattern in small-deal acquisitions is the capital partner plus operating partner split.

Co-GP Structures. A specific flavor of joint venture where two general partners share sponsor economics — the acquisition fee, asset management fee, and promote — on a deal. One GP brings the capital relationship and balance-sheet guarantee while the other brings the deal, the operations, and the boots-on-the-ground management. Co-GP splits are common in larger multifamily and commercial deals where the check size, net-worth requirement, or lender relationship exceeds any single sponsor’s capacity. The key document is a co-GP agreement that defines each party’s scope, the promote split, and what happens if one party fails to perform.

II. Institutional & Conventional Debt

Debt sits above equity in the stack: it is senior, it gets paid first from cashflow, and it carries a fixed cost — interest — rather than a share of profits. The more debt in the stack, the higher your return on equity, and the thinner your cashflow cushion.

Traditional Lending

Conventional lenders — banks, credit unions, and agency-backed originators — offer the cheapest debt in the market. The tradeoff is underwriting: they examine you, not just the deal.

Bank Financing. Conventional commercial loans from national, regional, and community banks. Terms typically run 5-25 years with rates tied to SOFR or prime plus a spread. Banks want strong personal financials, two years of tax returns, a 25-30% down payment, and often a personal guarantee. Community banks are frequently more flexible than nationals on Main Street acquisitions because their loan officers know the local market and the asset class. A commercial mortgage broker can widen your access to bank programs without you cold-calling loan officers.

Credit Unions. Member-owned financial cooperatives that sometimes offer more favorable terms than banks on owner-occupied commercial real estate and small business loans. Because credit unions are not-for-profit, they can price below market on rate and fees — but their commercial lending programs are generally smaller in scale and geographic reach than bank offerings. If you bank with a credit union, ask about their commercial desk before walking into a competing bank.

Agency Loans (Fannie/Freddie/HUD). Multifamily and commercial loans originated through government-sponsored enterprise programs. Fannie Mae and Freddie Mac offer 5-30 year fixed-rate terms at some of the lowest spreads in the market, but only for stabilized multifamily properties (typically 5+ units). HUD/FHA loans — 221(d)(4) for construction and substantial rehab, 223(f) for acquisition and refinance — offer terms up to 35 years fully amortizing, non-recourse, and at rates competitive with or below bank debt. The cost: a 6-12 month timeline, heavy documentation, and the requirement that the property meet agency underwriting standards on condition, occupancy, and environmental review. Agency debt is the cheapest source in the entire stack for qualifying multifamily assets — but it rewards patience and punishes anyone in a hurry.

Commercial Mortgage Brokers. Intermediaries who shop your deal to multiple lenders simultaneously and can access programs you would not find on your own. A good broker earns their fee by matching your deal profile to a lender’s specific appetite: one lender loves self-storage and hates restaurants, another is the reverse, and the broker knows which is which before you waste weeks applying to the wrong desk. Find a broker who specializes in your asset class, not a generalist.

Portfolio Lenders. Banks and private lenders who hold loans on their own books rather than selling them into the secondary market. Because they are not bound by agency underwriting standards or secondary-market delivery requirements, portfolio lenders can be more flexible on property condition, borrower profile, and deal structure — but they typically charge a rate premium for that flexibility and may require a personal guarantee where an agency lender would not.

Alternative Lending

When conventional lenders say no — because the deal is small or non-standard, the borrower is foreign or self-employed, or closing speed matters — alternative lenders fill the gap.

DSCR Loans. Non-QM rental property loans underwritten on the property’s cashflow, not the borrower’s personal income. No tax returns, no W-2s, no employment verification. The property’s rent divided by its debt service is the entire underwriting. DSCR loans are the workhorse for rental portfolio builders, BRRRR investors, and foreign nationals who cannot (or prefer not to) document US personal income. Typical terms: 30-year fixed, 7-9% rate, 70-85% LTV on purchase, 0.75-1.25 minimum DSCR depending on the lender. See the full breakdown at the linked article.

Equipment & Asset-Based Loans. Financing secured by business equipment or hard assets rather than by personal credit or business financials. For asset-heavy acquisitions — laundromats with commercial machines, car washes with tunnel systems, manufacturing facilities — the lender values the collateral first and the borrower second. This makes asset-based lending viable for buyers who cannot pass conventional underwriting but are acquiring a business with hard-asset backing. Lenders active in this space include Crest Capital, Balboa Capital, Beacon Funding, and National Funding.

Mezzanine Financing. Junior debt that sits between senior debt and equity in the stack — subordinate to the first mortgage but senior to common equity. Mezzanine lenders charge 12-20% interest and often receive warrants or an equity kicker (a right to buy equity at a discount) in addition to the interest coupon. Mezzanine is used to fill the gap between what a senior lender will provide and the total capital required. It is expensive but can bridge a deal that would otherwise die on the equity gap — and it is cheaper than selling common equity if the deal performs. Mezz is most common in middle-market acquisitions ($5M-$50M) and commercial real estate recapitalizations, less so in sub-$2M Main Street deals.

Preferred Equity. A hybrid instrument that acts like debt — fixed preferred return, paid ahead of common equity — but sits in the equity layer of the stack for tax and structural purposes. Preferred equity investors get a negotiated current pay rate (typically 8-12%) and often a share of the promote above a hurdle. It costs more than senior debt but does not carry the same personal guarantee exposure, and it does not dilute common equity control in the way selling more common shares would. Preferred equity is increasingly used by real estate sponsors to fill the gap between agency debt proceeds and total capitalization on multifamily acquisitions.

SBA Loans. Government-guaranteed loans through the 7(a) program that can cover up to 90% of a business acquisition with 10-year amortization. The most powerful structure within SBA is the seller note on standby: a seller carries 10-20% on a subordinated note with no payments due for 24 months, and SBA counts that note as the buyer’s equity injection — turning a 10%-down deal into a closing-costs-only close. Key limitation: SBA 7(a) requires a personal guarantee from every 20%+ owner, and that guarantor must be a US citizen or Lawful Permanent Resident. Buyers outside that eligibility window need the alternatives covered in the linked article — seller financing, DSCR, sale-leaseback, and JV structures.

Foreign-National Loans. A lender category specifically built to underwrite non-resident and ITIN-only buyers. These lenders evaluate the asset and the deal economics, not a US Social Security number or FICO score. Terms typically include LTV caps of 70-80%, a 1-2% rate premium over domestic equivalents, and a US LLC as the borrowing entity. DSCR foreign-national programs are the most common product in this segment. For buyers without a US credit profile, this is the direct path to institutional debt — covered in full at the linked article.

III. Creative & Structured Finance

Creative finance operates alongside or above the traditional capital stack — it replaces institutional debt and equity with seller-carried structures, existing debt, and real-estate recapitalization. These structures are the core of the Creative Finance hub and the practical engine behind the No Money Down playbook. Here they are mapped within the stack framework.

Seller Financing. The seller carries a promissory note for part or all of the purchase price, acting as the bank. The buyer pays the seller monthly over an agreed term and rate — no bank origination fees, no appraisal, no credit committee. Seller financing is the most versatile tool in the stack because it can serve as both equity replacement (when paired with bank debt, where a standby seller note counts toward the equity injection) and full debt replacement (when it is the sole financing on a deal). According to acquisition educators and broker surveys, seller financing appears in roughly 60% of small business sales in some form.

Subject-To / Loan Assumption. Acquiring a property by taking over the seller’s existing mortgage payments without formally assuming the loan — the loan stays in the seller’s name while the deed transfers to the buyer. This lets you acquire properties carrying 2-4% legacy debt that you could not originate today at any price. The due-on-sale clause is the documented legal risk; in practice, lenders rarely accelerate performing loans. Subject-to effectively transfers the cheapest debt in the market from the seller’s balance sheet to your deal.

Hybrid Sub-To + Seller Finance. The combination of subject-to (taking over existing low-rate first-position debt) with seller financing (a second-position note covering the equity above the loan balance). For a property worth $200,000 with a $120,000 mortgage at 3%, the buyer takes the existing loan subject-to and signs a separate seller note for the $80,000 equity at negotiated terms — capturing institutional-rate debt on the existing loan and flexible terms on the seller note in a single close.

Sale-Leaseback. When a business owns its real estate, the buyer sells the building to a sale-leaseback investor at close, using the proceeds to cover the business purchase price. The business continues operating under a long-term lease to the new property owner. Sale-leaseback is the most powerful $0-down structure in the entire stack because the real estate — not the buyer’s credit, citizenship, or cash — recapitalizes the acquisition. The investor underwrites the property quality and tenant creditworthiness, not the buyer’s personal profile. The US sale-leaseback market exceeds $7 billion annually, with active buyers for qualifying real estate across nearly every asset class.

Sub-To + Wrap Case Study. A real-world case study demonstrating how to layer subject-to loan assumption with a wrap-around mortgage on an actual deal. The walkthrough covers structuring, seller negotiation, legal considerations around the due-on-sale clause, and the post-close cashflow outcome — a concrete illustration of the hybrid stack in action.

A capital stack is only as good as your ability to assemble it. The No Money Down pillar is the practical playbook that shows how to combine these sources into structures that cost you little or none of your own equity — walking through the four doors (Buy a Business, Creative Finance, Cashflow Real Estate, and Financing) with worked deal math, seller conversation frameworks, and the honest budget you need before your first close.
