The short answer. Only after three tests pass. Return to Owner on the target reveals what the P&L is hiding. A certified business valuation confirms the market price. SBA underwriting confirms the deal is fundable. If the SBA declines to fund, the number is wrong. Seller financing does not fix the price. It buries it in a note the business's actual cash flow cannot service.
Test 1: Return to Owner On The Target
Before signing, run the diagnostic on the target business the same way you would run it on your own. What is the target's real MMP once debt service is grossed up and owner comp is restated to market? What is the Working Capital Gap? What is the Realized vs Intended Gross Margin cascade?
The target's P&L will show what the seller wants you to see. Return to Owner shows what the business actually delivers.
This is exactly the pattern in the HVAC buyer field note. The business was profitable. The debt service under the seller's proposed note was not.
Test 2: Certified Valuation
Handshake pricing kills more deals than any other single failure. A certified business valuation is not expensive. It is a fraction of a percent of the deal size. And it produces a defensible number backed by comparable transactions.
If the seller resists a valuation, that is a signal. If the seller's number is 15 to 25 percent above the certified valuation, that is another signal. Neither is a deal-killer on its own. Both require a conversation before the signing.
Test 3: SBA Underwriting
The SBA exists to fund small business acquisitions. Their underwriting is not perfect but it is defensible. They look at the target's historical cash flow against the proposed debt service and either approve or decline.
An SBA approval is not a guarantee the deal is a good idea. An SBA decline is a strong signal the number is wrong. When the SBA declines to fund a purchase, the market is telling the buyer the price does not match the business's actual cash-flow capacity.
Seller financing after an SBA decline is not a rescue. It converts an unfundable price into a signed deal by moving the risk from the SBA balance sheet onto the buyer's balance sheet. The buyer still has to service the note. The business still cannot generate the cash. The math has not changed. Only who is holding the paper has changed.
Frequently Asked Questions
What if the target is a great strategic fit?
Strategic fit does not fund debt service. Run the numbers first. If the numbers work, the strategic fit is a bonus. If the numbers do not work, the strategic fit is what people call the mistake later.
Can I combine my current business with the target for a better MMP?
Sometimes. Model it both ways: standalone target and combined operation. The combined case usually shows lower overhead per revenue dollar. It also usually adds integration cost that people underestimate. Run both models before making the pitch.
What if the seller wants me to hire their family members?
Load fully-loaded cost of every retained family member into Layer 2. If Layer Cake still clears with them included, you can commit. If it does not, negotiate their exit as part of the purchase. Do not carry someone else's payroll obligation into your new MMP.
Is there a rule of thumb multiple?
Trades typically 2.0 to 3.5 EBITDA. Professional services 3.0 to 5.0. Distribution 3.5 to 5.5. Manufacturing 3.5 to 6.0. These are ranges. The specific multiple depends on customer concentration, key-person risk, growth trend, and margin quality. Certified valuation determines the specific number.
