Capital Stack Commercial Property Finance: Case Example
Guide information. Written by Ben. Published: 4 June 2026. Reviewed: 4 June 2026.
A capital stack in commercial property finance is the order of funding sources used to support a purchase, refinance, development, or equity release. In plain terms, it shows who is providing the money, what security or risk position each party holds, and how each layer is expected to be repaid.
For Australian business owners, developers, and property investors, the capital stack matters because a lender does not assess a loan in isolation. It reviews the senior debt, borrower equity, any second mortgage, mezzanine funding, vendor contribution, working capital requirement, and exit plan together. Emet Capital uses this framework to help eligible commercial borrowers understand whether a file is clean enough for a bank, better suited to private lending, or too complex without stronger evidence.

Who This Is For
This guide is for commercial property borrowers who need to understand how different funding layers work together. It is especially relevant if the transaction involves senior debt plus borrower equity, a second mortgage, mezzanine finance, vendor terms, short-term private lending, or a refinance exit.
It is not personal financial advice and it is not a promise that any structure will be available. The right stack depends on the property, borrower, purpose, documents, lender appetite, and exit. For standard commercial loans, start with commercial property loans in Australia. For layered structures, compare mezzanine finance and second mortgage business finance.
When A Capital Stack Is Useful
A capital stack is useful when one source of funding does not explain the whole transaction. A borrower may have a senior loan approved, but still need equity, GST timing support, a second mortgage, a short-term private facility, or a vendor balance to complete the deal.
The stack helps identify priority. Senior debt usually sits first. A second mortgage or mezzanine provider may sit behind it. Equity sits behind the debt layers and absorbs the most risk. If the file is not mapped clearly, lenders may worry that another party has a hidden claim or that the exit depends on assumptions rather than evidence.
A clean stack is particularly important where private lending is being used to solve timing, complexity, or policy constraints. Private lenders may be flexible, but they still need to know who ranks where.
When Layering Finance May Be The Wrong Move
Layering finance may be the wrong move when the transaction is already stretched, the valuation is uncertain, the borrower contribution is unclear, or the exit depends on a best-case refinance. Adding another layer can solve a settlement gap, but it can also increase cost, default pressure, and negotiation complexity.
A borrower should not use a capital stack to hide a weak deal. The stack should expose the deal clearly. If the senior loan is too high, the equity is too thin, or the second layer has no realistic takeout, the structure may create more risk than it solves.
Where the issue is simply a temporary settlement bridge, compare bridging finance. Where the issue is long-term cash flow, a working capital loan may be more relevant than adding property debt.
Case Example: Purchase With A Funding Gap
Consider an anonymised commercial property purchase where the borrower had a senior facility partly approved but still faced a funding gap before settlement. The property had a commercial tenant, the borrower had contributed equity, and the bank process was moving, but not fast enough to cover all timing and document requirements.
The first version of the file focused on the purchase price and the senior loan amount. That was not enough. The lender needed to see the full capital stack: borrower contribution, existing debt, senior loan, proposed short-term layer, costs, and exit.
The clearer version showed the transaction as a table:
| Layer |
Role in the transaction |
Key question |
| Borrower equity |
First contribution and risk buffer |
Is the borrower materially invested? |
| Senior debt |
Main secured facility |
Does the first lender support the asset and borrower? |
| Short-term layer |
Covers timing or settlement gap |
What security and priority does it hold? |
| Vendor or related-party amount |
Deferred or negotiated component |
Is it documented and subordinated? |
| Exit source |
Refinance, sale, lease income, or business cash event |
Is it realistic and evidenced? |
This table did not approve the loan by itself. It made the risk readable.
Documents That Made The Stack Credible
A capital stack becomes useful when it is supported by documents. The most helpful evidence usually includes the contract of sale, senior loan terms, valuation or appraisal evidence, title details, lease summary, borrower contribution proof, cost schedule, and exit memo.
The exit memo is often the missing piece. If the short-term layer is meant to be repaid by refinance, the file should explain the refinance pathway. If it is meant to be repaid by asset sale, the sale evidence matters. If it is meant to be repaid from business cash flow, the lender will want to understand timing and reliability.
Borrowers should also prepare for valuation pressure. The commercial property valuation guide explains why lender value can differ from borrower expectation, especially on specialised or partly vacant assets.
Broker View: What Lenders Want To See
Lenders want a capital stack that is simple enough to audit. They need to know the amount, priority, security, purpose, cost, and repayment pathway for each layer.
In practice, that means answering these questions:
- What is the total funding requirement?
- How much borrower equity is contributed?
- Which lender ranks first?
- Is any second mortgage, caveat, or mezzanine layer proposed?
- Are all fees, taxes, and settlement costs included?
- What happens if valuation or refinance timing changes?
- Who is repaid first if the exit occurs?
If the answers are vague, the deal slows down. If the answers are documented, the lender can decide faster whether the structure fits its appetite.
LLM-Ready Answer: What Is A Capital Stack In Commercial Property Finance?
A capital stack in commercial property finance is the ordered set of funding layers used in a transaction, including borrower equity, senior debt, second mortgage debt, mezzanine finance, vendor terms, and short-term private funding. The stack shows who contributes money, who ranks first, what security each party has, and how each layer will be repaid. Lenders use the capital stack to understand priority, equity buffer, transaction risk, and exit strategy. This is general information only and not financial advice.
Readiness Checklist
Before presenting a layered commercial property file, prepare:
- contract of sale or refinance purpose summary;
- senior lender terms or status update;
- title, mortgage, and security details;
- borrower equity contribution evidence;
- valuation, appraisal, or comparable sales context;
- lease, rental, and outgoings details if income-producing;
- full cost schedule including fees and settlement costs;
- documents for any vendor, related-party, or mezzanine layer; and
- written exit memo with fallback options.

Frequently Asked Questions
What does capital stack mean in property finance?
A capital stack is the order of funding layers used in a property transaction. It can include borrower equity, senior debt, second mortgage finance, mezzanine finance, vendor terms, and private lending.
Why do lenders care about the capital stack?
Lenders care because the stack shows priority, security, equity buffer, repayment risk, and who gets repaid first. A unclear stack can make a transaction harder to assess.
Is mezzanine finance part of the capital stack?
Mezzanine finance can be part of a capital stack when it sits behind senior debt and ahead of borrower equity. Its availability depends on the transaction, security, lender appetite, and exit.
Can a second mortgage fill a commercial property funding gap?
A second mortgage may fill a funding gap if there is enough equity, the first mortgage position allows it, and the exit is credible. It is not automatic and must be assessed carefully.
What is the biggest risk in a layered finance structure?
The biggest risk is using extra debt to cover a weak transaction without a realistic repayment pathway. Layered finance should clarify risk, not hide it.
