Business Acquisition Criteria for Passive Investors: The Deal Screen I Use

Business acquisition criteria for passive investors are the go/no-go filters that qualify a lower-middle-market target for investment without requiring the investor to run the company post-close. The seven non-negotiables: three-plus years of verified cash flow, DSCR at or above 1.5x, a capable second-in-command already in place, sub-15% customer concentration, an operator (in-house or hired) who owns day-to-day P&L, a defined 3-7 year hold with a mapped exit, and terms that hit a base-case IRR of 20% or better after debt service and management fees.

Look, if you’re an angel writing a check into a search fund, a family office allocating to lower-middle-market buyouts, or a syndicate LP joining an operator on a specific target — you need a criteria list that protects your capital when you’re not the one signing invoices. This isn’t a first-time buyer’s checklist. It’s a passive-investor screen.

I’ve done 300+ deals over 30 years, and I’ve been on both sides — as the operator taking capital and as the investor writing the check. The criteria below are the ones I actually use. The same framework we walk on live deals inside Dealmaker Academy.

Why Passive-Investor Criteria Look Different

An owner-operator can compensate for a weak team, missing SOPs, or a soft customer list by rolling up their sleeves. A passive investor cannot. When you’re not in the seat, execution risk becomes counterparty risk — and every gap in the target becomes a gap in your returns.

That’s why an angel, family office, or syndicate LP has to weight the same criteria differently than an owner-operator. Owner dependency isn’t a problem you can outwork. Systems gaps aren’t something you’ll patch on Tuesday. The deal has to stand up on its own before your capital goes in.

Financial Criteria: Cash Flow Is the Only Thing That Matters

The financial screen for a passive investor starts with verified cash flow, not top-line revenue. You are underwriting distributions and debt service. Everything else is decoration.

• DSCR at or above 1.5x. Non-negotiable. Debt service coverage under 1.5 means one bad quarter wipes your distributions and you’re funding a rescue capital call.
• 3+ years of consistent SDE or EBITDA. Not a hockey stick. Not a “COVID rebound.” Steady, boring, provable.
• Working capital normalized in the LOI. A target-working-capital peg protects you from a seller stripping the balance sheet on the way out.
• Cash-on-cash return of 25%+ in year one. After debt service, after management fees, after CapEx. If the math doesn’t get there under conservative assumptions, the deal isn’t priced right.
• Base-case IRR of 20%+ over the hold. Model best/base/worst. If base doesn’t clear 20% before your target multiple on exit, pass or restructure.
• Surplus cash in the business at close. Not swept by the seller. This is the buffer that keeps a hiccup from becoming a crisis.

Operational Criteria: Who’s Running It When You’re Not?

The single biggest failure mode for passive capital in the lower middle market is the “orphaned deal” — the seller walks, no operator was ever named, and the LPs are stuck watching returns evaporate. Solve this in criteria, not after close.

• An operator is identified before you fund. Search-fund principal, ETA operator, hired GM, or a stay-on management team with real equity in the outcome. If the deal doesn’t have one, you don’t have a deal.
• A capable #2 already in place. Even with a new operator on top, someone inside needs to know where the bodies are buried on day one.
• Documented SOPs for the top 10 revenue-producing processes. If everything runs on the outgoing owner’s head, price the write-down of that knowledge loss into the offer.
• Key employees under retention agreements before close. Before. Not “we’ll talk to them after.” Before.
• A clean org chart with real P&L ownership. If one person “does everything,” the business is a job with a logo. That’s not investable at passive scale.

Market and Customer Criteria: What Protects the Cash Flow

Passive investors lose more money to concentration risk than to overpayment. One customer, one supplier, one platform — three ways the same story ends. Screen for durability, not just growth.

• No single customer above 15% of revenue. Above that, it isn’t a strength; it’s a weakness in a suit.
• Top 5 customers under 40% combined. This is the actual diversification test.
• Recurring or repeat revenue mix. Contracts, subscriptions, and reorder patterns are worth a materially higher multiple than one-time transactional sales.
• Industry with a 5-year outlook that isn’t shrinking. Pull the IBISWorld or trade-association forecast. A great business in a dying category is still a bad deal.
• Not platform-dependent. If the business survives because of one Amazon account, one Google ads channel, or one distributor, that platform can change terms overnight and your returns die with it.

Deal Structure Criteria: Terms Over Price

Focus on terms over price. A seller-financed deal at 90% of asking with a 5-year note beats an all-cash deal at 70% of asking every day of the week — because the terms are what generate cash-on-cash returns for the passive investor. This is the lever most LPs and family offices underuse.

• Seller note of 20-40% of purchase price. Keeps the seller aligned through the transition and preserves your cash for working capital and growth.
• Earnout tied to defined post-close metrics. Protects against seller-inflated numbers and rewards them for delivering the story they sold you.
• Reps and warranties with meaningful indemnification. Escrow or holdback of 10%+ for 12-24 months.
• Working-capital peg and true-up. Prevents the seller from sweeping cash and leaving you undercapitalized.
• Management fee and carry structure that aligns the operator. Standard is 2% management fee, 20% carry over an 8% preferred return. Adjust for deal size and risk.
• Defined 3-7 year hold with a mapped exit. Strategic sale, recap, or roll-up. If nobody at the table can articulate the exit, you don’t have one.

Due Diligence Criteria: What You Verify Before You Wire

Due diligence for a passive investor is not a checklist you delegate and forget. Every criterion above has to be independently confirmed by someone who works for you, not the operator.

1. QoE (Quality of Earnings) report from an independent CPA. Reconciles reported earnings against tax returns, bank statements, and bookings. Discrepancies are the first weakness to price into the deal.
2. Legal DD by an M&A attorney. Contracts, IP, employment agreements, litigation, tax compliance with the IRS, and any SEC exposure if you’re structuring as a fund.
3. Customer calls under NDA with the top 5. Confirm the relationship, the concentration, and the renewal risk. Sellers hate this. Do it anyway.
4. Operator background and reference check. If a search-fund principal or ETA operator is running the deal, treat them the way an LP treats a first-time GP. Track record, references, personal capital in the deal.
5. Bank and lender pre-qualification for SBA or conventional financing. Before you commit equity, confirm the debt stack the model depends on is actually financeable.

How to Score a Target Against These Criteria

Score each of the five criteria categories — financial, operational, market, structure, DD readiness — from 1 to 5. Total out of 25.

• Below 15: Pass. The gaps that would need to close before you fund are gaps the seller is unlikely to fix.
• 15-20: Yes with negotiated protections. Every soft criterion becomes a deal-structure lever — a bigger seller note, a longer earnout, a larger escrow, a lower valuation.
• 21+: Move fast. A clean lower-middle-market target that scores above 21 will attract multiple bidders. Speed and certainty of close win these.

Red Flags That Kill Passive-Investor Deals

Some red flags mean walk away no matter how the rest of the criteria score:

1. Books that don’t reconcile. P&L, tax returns, and bank statements disagree by more than a rounding error. Something is either sloppy or hidden — either way, not investable at passive scale.
2. Undisclosed litigation, tax issues, or regulatory action. These surface in DD. If they surface late, walk.
3. Seller refuses reasonable reps, warranties, or an earnout. A seller who won’t stand behind their own numbers is telling you the numbers won’t stand.
4. No operator, and none available. The most common orphaned-deal scenario. Solve this before you fund or don’t fund.
5. Cyclical industry at the peak. Home services, construction, discretionary retail bought at the top of the cycle. Your hold period will span the downturn, not the recovery.

Valuation Anchors Passive Investors Use

Alongside the criteria screen, three valuation methods anchor what you’ll actually pay:

1. Comparable Company Analysis. Multiples paid on similar recently-transacted businesses at similar size, sector, and growth profile.
2. Discounted Cash Flow. Project cash flows across the hold, discount at your required return, back into an entry multiple that works.
3. Precedent Transactions. Actual deals closed in the sector. Broker data, PitchBook, or lender comps. This is what people actually paid, not what they asked.

Recurring-revenue businesses trade at a premium. Owner-dependent service businesses trade at a discount. Adjust the multiple to the model, then stress-test the entry price against your base-case IRR. If it doesn’t clear the hurdle, the deal isn’t the deal — the price is.

Frequently Asked Questions

What are the key acquisition criteria for a passive investor?

The seven non-negotiables are three-plus years of verified cash flow, DSCR at or above 1.5x, a capable second-in-command already in place, single-customer concentration under 15%, a named operator with equity in the outcome, a defined 3-7 year hold with a mapped exit, and terms that hit a base-case IRR of 20% or better after debt service and fees.

How does a family office or angel screen deals differently than a first-time buyer?

A first-time buyer can compensate for weak systems, missing SOPs, or owner dependency by working inside the business. A passive investor — family office, angel, or syndicate LP — cannot. So the screen weights operator quality, systems maturity, and counterparty alignment much more heavily than an owner-operator’s screen does. Gaps you can’t outwork have to be priced or walked away from.

What DSCR is required for a passive investor to fund a deal?

Debt service coverage of 1.5x or higher, minimum. Under 1.5, one soft quarter wipes distributions and forces a rescue capital call. DSCR at or above 1.5x is non-negotiable in our framework because the whole passive-investor thesis depends on the business servicing debt without the investor stepping in.

What cash-on-cash return should a passive investor target on a lower-middle-market buyout?

25% or better in year one, after debt service, management fees, and CapEx. Base-case IRR over the full hold should clear 20% before the exit multiple. If the model doesn’t get there under conservative assumptions, the deal isn’t priced right for passive capital.

How much customer concentration is acceptable in an acquisition target?

No single customer above 15% of revenue, and the top five combined under 40%. Above those thresholds, concentration risk swamps the return math for a passive investor because you can’t personally save an at-risk customer relationship the way an owner-operator can.

What deal terms protect a passive investor most?

Terms over price. A seller note of 20-40%, an earnout tied to post-close metrics, meaningful reps and warranties with 10%+ escrow for 12-24 months, a working-capital peg, and management-fee and carry alignment with the operator. These terms convert seller-inflated numbers into seller-shared risk and preserve the cash-on-cash math that passive capital depends on.

What hold period should a passive investor plan for?

Three to seven years, with a mapped exit — strategic sale, recap, or roll-up. If nobody at the table can articulate a specific exit path when you fund, you don’t have one. Long-duration illiquidity is the tax you pay for private-market returns; only pay it against a defined exit.

How does a syndicate LP evaluate the operator on a specific-deal acquisition?

Treat a search-fund principal or ETA operator the way an LP treats a first-time GP. Full track record, personal capital in the deal, references from prior sellers or investors, and clarity on compensation, carry, and preferred return. Operator alignment is where passive returns are won or lost.

Where can passive investors learn to run this screen on live deals?

Dealmaker Academy walks the criteria screen on real lower-middle-market targets with Carl Allen and the coaching team. The Protégé Community is where active dealmakers and investors share deals, screens, and outcomes with each other. Both are built for people funding and running deals, not people reading about them.
