SBA 504 senior debt debenture and interim funding

An SBA 504 financing plan needs two funds schedules: the permanent capital structure and the cash available before permanent funding is complete. A borrower can have a balanced long-term plan and still lack the interim money needed to acquire, construct, or complete the project.

13 CFR 120.801 describes the general structure: borrower contribution, a third-party loan, and financing from a CDC debenture, with interim financing usually required. The SBA’s 504 overview describes collaboration between the Certified Development Company and senior lender for eligible fixed-asset projects. The actual proportions, conditions, and timing must be confirmed for the transaction.

Identify each funding obligation

List the senior lender, interim lender if different, CDC, borrower, and settlement parties. For each, record the amount, legal obligation, conditions, availability period, and repayment source. The same institution may perform more than one role, but its obligations should still be separated.

Ask who advances the portion expected to be repaid from debenture proceeds and what happens if debenture funding is delayed or reduced. Determine whether the interim lender has committed to a defined amount and duration or merely indicated willingness to consider the bridge.

Do not describe the whole financing package as a single fixed-rate loan without reviewing each component. The senior and interim loans have their own economics and documents. The debenture component’s rate and payment characteristics do not automatically apply to the entire project.

Build a three-stage funding timeline

An original timeline can use the following format:

Track cumulative cash, not only final percentages. Identify which source pays each invoice and whether the borrower must first advance the money. A cost can be eligible in the final project while still requiring temporary funding today.

Work through a hypothetical bridge

Assume a $4 million eligible project is modeled with $2 million of senior debt, $1.6 million of debenture-funded financing, and $400,000 of borrower equity. These proportions are illustrative; they are not a conclusion about the required contribution for a particular project.

If the project must be fully funded before the $1.6 million debenture proceeds arrive, the interim funding plan must cover that amount. Assume an interim lender advances the entire $1.6 million for 90 days at a hypothetical 8% annual rate using simple Actual/360 interest. Interest for that period is $32,000.

If funding instead takes 150 days, interest becomes approximately $53,333, an increase of approximately $21,333. The delay also extends the period during which interim loan conditions apply. A permanent sources-and-uses schedule that omits this carrying cost understates the borrower’s exposure.

The example assumes a constant outstanding balance. A construction draw schedule requires interest on actual funded balances over time. Fees, extension costs, and other interim charges must be added under the real proposal.

Reconcile eligible costs and actual costs

Maintain an itemized cost ledger with invoices, payments, approved changes, and the proposed financing treatment. Separate the project’s economic budget from the amount accepted for the 504 structure. A necessary business expense is not automatically an eligible fixed-asset project cost.

Suppose final accepted debenture-funded proceeds are $1.5 million instead of the modeled $1.6 million. The interim payoff has a $100,000 principal gap before accrued interest and fees. Identify whether the borrower supplies that amount, another approved source covers it, or the project must be restructured.

Do not assume that unused money in another budget category can be redirected without approval. Confirm cost eligibility, source restrictions, and the conditions for any adjustment with the CDC and lenders.

Review the permanent loans together

Compare the senior loan’s maturity, amortization, rate changes, collateral, and prepayment provisions with the debenture component. A long amortization does not mean the senior loan has the same maturity. A later senior refinance can become a significant business-plan event while the other component remains outstanding.

Prepare a combined debt-service schedule and principal-balance chart. Include rate-reset scenarios where applicable. Reconcile the borrower’s payment instructions and servicing responsibilities for each obligation after funding.

The borrower should also understand how future property transfers, business changes, or additional debt are handled. Obtain transaction-specific advice rather than assuming that paying one component releases every restriction affecting the project.

Put the completion package on the critical path

Ask the CDC and lenders for the exact completion and funding requirements, their owners, and the expected review sequence. Track submitted, accepted, and outstanding items separately. A project physically finished in the field can still have unresolved documentation or funding conditions.

Before the interim maturity approaches, confirm the remaining steps and a documented response to delay. Do not count an unapproved extension as available time.

A complete 504 plan explains who funds the project at each stage, who bears interim costs, and how the final loans repay the temporary advances. That makes the financing reviewable as a cash sequence rather than a static percentage diagram.
