Firehouse Subs total investment + what lenders look at

Total estimated initial investment per the current FDD runs $178K–$724K depending on unit format (end-cap, in-line, or conversion), geography, and new vs. acquired unit. Lenders evaluate the following when underwriting a Firehouse Subs franchise deal:

• Equity injection documentation: SBA requires a minimum 10–20% of total project cost in non-borrowed liquid cash.
• Net worth and liquidity: Firehouse Subs / RBI discloses financial thresholds in the FDD — lenders verify before structuring the loan.
• Location format: End-cap vs. in-line vs. freestanding units carry different build-out costs; lenders model DSCR accordingly.
• Location cash flow (existing unit): Trailing 12-month revenue; DSCR of 1.25x or better for acquisitions.
• Personal credit: 680+ personal FICO is a common SBA lender threshold for franchise deals in this investment range.

SBA 7(a) for Firehouse Subs franchises

The SBA 7(a) loan program is the primary financing vehicle for Firehouse Subs franchise acquisitions. Firehouse Subs' listing on the SBA Franchise Directory allows lenders to bypass independent franchise agreement review — shortening timelines by 2–4 weeks. Key parameters:

• Maximum loan amount: $5M — covers most single-unit and some multi-unit Firehouse Subs deals
• Terms: Up to 10 years for equipment and working capital; up to 25 years when real estate is included
• Rate: Prime + 2.75% for loans over $350K (variable); fixed-rate options vary by lender
• Use of proceeds: Acquisition price, leasehold improvements, steam and food prep equipment, working capital reserve
• What it does NOT cover: The equity injection — that must come from borrower's own liquid assets

SBA 504 for real estate and build-out

The SBA 504 program applies when a Firehouse Subs franchisee is acquiring freestanding real estate as owner-occupied commercial property. Structure: 50% conventional bank loan + 40% SBA 504 debenture (long-term fixed rate) + 10% borrower equity. Most Firehouse Subs locations are in leased strip-center spaces — 504 is most relevant for multi-unit operators who plan to own their commercial real estate.

Equipment financing for Firehouse Subs

Commercial steamers (central to Firehouse Subs' hot sub preparation method), bread ovens, refrigeration, and POS technology can be financed separately via equipment loans or leases — layered on top of the primary SBA 7(a) loan. Equipment loans typically run 3–7 year terms, collateralized by the equipment itself. Firehouse Subs' steaming process requires specific equipment that distinguishes it from cold-sub competitors and warrants standalone financing consideration.

Franchisor financing programs

Firehouse Subs (under RBI ownership) does not operate a direct in-house lending program for franchisees. RBI has offered development incentive programs across its brands for qualified multi-unit operators, but these are operational incentives, not direct financing products. The actual debt financing is market-rate from third-party lenders.

Down payment and liquidity requirements

Firehouse Subs discloses franchisee financial requirements in the current FDD — review Item 5 and Item 7 with your lender before approaching any financing. At $178K–$724K total investment, the SBA equity injection (10–20%) runs $18K–$145K from liquid assets. The lower investment floor — particularly for in-line conversions at the bottom of the range — makes Firehouse Subs one of the more accessible branded sub franchise concepts for first-time franchisees.

Timeline to funding

1. Pre-qualification: Lender reviews financial statements, Firehouse Subs / RBI approval letter, and FDD. 1–2 weeks.
2. SBA package: Full SBA application: SBA Form 413, 3 years tax returns, business plan, site lease or purchase agreement. 2–3 weeks.
3. SBA approval: SBA review and conditional commitment. 3–6 weeks depending on lender's Preferred Lender (PLP) status.
4. Closing and funding: Title, legal, and closing. 2–3 weeks post-commitment. Total: 60–90 days from complete application.

What lenders look for in a Firehouse Subs franchise application

Here are the five factors SBA lenders evaluate when underwriting a Firehouse Subs franchise deal (per SBA SOP 50 10 7):

• Equity injection: Wide investment range ($179K–$737K) spans SBA Express eligibility at the lower end to standard 7(a) for new builds. SBA equity injection is 10–20% of project cost. On a $400K Firehouse conversion, that's $40K–$80K in documented non-borrowed liquid funds. Conversion builds are a common entry path and typically lower cost than from-scratch new builds.
• DSCR and premium fast-casual pricing: Firehouse Subs operates in the premium fast-casual segment with higher average ticket sizes than standard QSR sandwich concepts. The 9% combined fee load (6% royalty + 3% ad fund) is manageable against Firehouse's AUV at mature units. Lenders model DSCR using trailing 12-month AUV data from the FDD Item 19 financial performance representations.
• RBI parent company and franchise system risk: Restaurant Brands International (RBI — parent of Burger King, Tim Hortons, Popeyes) acquired Firehouse Subs in 2021. Lenders assess franchise system risk as part of SBA underwriting; RBI's institutional infrastructure and established preferred-lender network reduce system risk in the underwrite versus independent or PE-backed franchisors.
• Conversion vs. new build structure: Firehouse Subs has a significant conversion build-out model (existing restaurant shell → Firehouse). Conversions run $179K–$400K vs. $500K–$737K for from-scratch new builds. Lenders apply different collateral and timeline risk to each — conversions have lower build-out risk and cost certainty but may involve existing lease assumption analysis.
• Brand positioning and community loyalty: Firehouse Subs donates a portion of every purchase to public safety foundations — a brand identity tied to local firefighter and first responder communities. This drives community loyalty and repeat customer base in markets with strong public safety presence. Lenders with Firehouse experience treat strong community ties as a soft revenue stability signal alongside DSCR data.

Deal structuring note

Firehouse Subs' RBI ownership is a meaningful underwriting comfort factor — institutional franchisor support reduces system risk in the lender's SBA analysis. The conversion-heavy expansion model means build-out timelines and cost certainty are generally better than new-construction peers; document conversion vs. new build clearly in your lender package, as the underwriting treatment differs between the two. Lower-end conversions ($179K–$350K) may qualify for SBA Express loans, reducing approval time from 60–90 days to 36 hours for the SBA review stage.
