1. In an SBA acquisition:

• If the business fails, everyone goes to zero—buyer, investors, and bank.
• If the business does okay, the bank gets back principal plus a fixed interest rate spread.
• If the business is a home run, the buyer’s and investor’s upside is uncapped… and the bank still just gets its fixed rate or return.

Banks also:

• Have a cost of funds (they’re paying depositors).
• Earn only a net interest margin, not huge windfalls.
• Can afford very few loan losses because their upside is capped.

Result:
Banks must underwrite to a very low probability of default.

Unlike equity investors, they can’t say “a few strikeouts are fine if we get some 10x winners.” So when your deal feels like a great “bet,” they’re asking only one question: How likely is this to default?

Before a lender signs off, they want to feel comfortable across four pillars:

1. Historical Cash Flow Coverage

• Focus is on historical, not pro forma, cash flow.
• Using the last 3 years + interim, can the business support new debt payments with a margin (typically DSCR ≥ 1.25–1.30x)? Also pay attention to revenue and margin trends. Banks want flat to gradual growth, not downward trends and also not “hockey stick” growth either.

2. Capability: Are You the Right Operator?

• Direct experience is ideal in some industries.
• In others, you need to clearly demonstrate transferable experience: leadership, P&L, operations, sales, etc., directly tied to the target business.

3. Collateral

• Most SBA acquisition loans are effectively cash-flow loans with limited collateral.
• Real estate collateral helps minimize potential lender losses; but general business assets rarely move the needle in getting a lender comfortable.

4. Structure & Conditions

• Subordinated seller notes, standby periods, and other structural terms help protect the bank when cash gets tight.
• The more “cushion” and alignment you build in, the more comfortable lenders can get.

Heather’s simple but important rule of thumb:

Lenders can usually tolerate one significant, well-mitigated risk in a deal. Two or more, and it’s often a “no.”

Each major risk—customer concentration, no industry experience, lumpy financials, licensing, rapid growth—is a potential point of failure. Stack a few together and the probability of default jumps beyond what their “low probability of default” model can absorb.

If your deal has:

• Zero serious risks: great (and rare).
• One major risk: you’ll need a strong, thoughtful mitigation.
• Two or more major risks: likely not bankable, even if you’re comfortable as an investor.

What it is

• One customer ≥ ~20% of revenue, or
• Top 3–5 customers ≥ ~30–40% of revenue.

This is common in small businesses—and dangerous. Buyers regularly report losing key customers within the first year after closing on their acquisition, often because the seller mentally checked out during the sale process or because relationships were overly tied to the founder.

How lenders think
They’re asking: If that big customer leaves, can you still pay the SBA loan?

How to mitigate it

• Quantify contribution, not just revenue
  • Determine the margin and true EBITDA contribution of the concentrated customer(s).
• Stress-test DSCR
  • Remove that contribution from your cash-flow model.
  • Recalculate DSCR as if that customer disappeared.
  • You should at least be around 1.00x on SBA debt in this downside scenario—and ideally above.
• Use structure to right-size risk
  • Larger equity check to reduce leverage.
  • Forgivable, subordinated seller note, on standby for 1–2 years and tied to customer retention. If that customer (or group) disappears, the note is forgiven or reduced, effectively lowering your true purchase price.

Serious concentration with no math and no mitigation is one of the fastest paths to a declined loan.

Many business buyers don’t have direct industry experience—but they do have carefully framed, lender-friendly transferable experience.

Some industries, however, almost require direct experience alignment:

• Heavy manufacturing
• Engineering and technical services
• Certain healthcare sectors
• Specialized licensed trades

If you do have those skills, you may be in a smaller buyer pool and more attractive to lenders. If you don’t, you need to build a very clear story.

How to mitigate it

• Understand the seller’s role in detail
  What do they actually do day to day? Who controls sales, ops, technical work, hiring, key relationships?
• Build a people-heavy transition plan
  Emphasize:
  • Seller handoff timeline and responsibilities.
  • Retention and roles of key employees.
  • How customer relationships will be transitioned and protected.
• Translate your resume to this business
  Don’t just send a generic CV. Spell out:
  • Relevant leadership and P&L ownership.
  • Operational experience similar to this company’s reality.
  • Any sector-specific overlaps.
• Be sharp in underwriting interactions
  Lenders form opinions based on how you answer questions. Poor or fuzzy answers about the industry, operations, or sales model can quietly kill a deal even if your paper credentials look fine.

Lenders want predictable:

• Flat to gently rising revenue
• Stable margins
• No big surprises year to year

Red flags include:

• Revenues jumping up and down.
• Adjusted net margins that swing wildly (often a sign of aggressive or inconsistent add-backs).
• Lumpy “project” revenue with unclear drivers.

How to mitigate it

• Investigate the root cause
  Is this bad bookkeeping, timing, or real volatility? A quality of earnings (QoE) can be invaluable on larger deals.
• Normalize add-backs
  Remove or reduce questionable add-backs until adjusted margins look consistent and believable.
• Size the loan to the worst year
  Set your loan amount so DSCR is acceptable even if the business reverts to the lowest recent year, not just the peak.

If you can’t tell a clear, coherent story about why performance is choppy—and why you’re comfortable with it—don’t expect your lender to be.

Licensed businesses (HVAC, plumbing, electrical, GC, certain healthcare and med spa models, etc.) have become much tougher after recent SOP changes.

Historically, seller rollover equity allowed the seller to keep their license and stay involved. Now, if the seller rolls equity and stays:

• The seller must personally guarantee the SBA loan for two years.
• All new owners (regardless of percentage) must personally guarantee for the life of the loan.
• The transaction must be a stock sale.

Many sellers simply won’t agree to that. At the same time, SBA still limits a fully bought-out seller’s employment to 12 months.

What lenders want

They want the personal guarantor on the loan to be the person who controls the license, so the business can’t easily “walk away” from compliance.

What sometimes works

• A licensed employee becomes a minority owner (often 1–10%) before closing and holds the necessary license.
• A robust license continuity plan:
  • How you’ll eventually secure your own license (if applicable).
  • Backup options if that key employee leaves.
  • Possibly an identified RMO/RME-type backup, as a contingency.

Even with this, many banks will still decline. If you don’t already have the license, you may want to focus on non-licensed industries until the rules or market practice change.

From an investor’s perspective, rapid growth is exciting. From a lender’s perspective, it creates this problem:

• The purchase price and debt are at least somewhat sized on the most recent “high” year.
• Prior years at lower levels can’t comfortably support that same debt.
• There is often only one period of proven DSCR at the new leverage level.

They also ask: If things are so good, why is the seller leaving now instead of riding the wave?

How to mitigate it

• More equity
  Reduce leverage so the business would still cover debt even if revenue slips toward lower historical levels.
• Performance-tied, forgivable seller note
  Use a standby seller note that only begins amortizing if revenue/EBITDA stays at or above a defined threshold over a couple of years. If not, the note is reduced or forgiven.
• Explain the growth engine clearly
  • What changed? New salesperson? Channel? Product?
  • Who owns key relationships? Can that be transitioned without breaking growth?
• Tight non-compete
  Especially important when the seller has been the driver behind that growth.
