Most diligence stories end with a lower price. This one ends with the buyer walking away.

Walking away feels like losing. You spent weeks on the deal, paid an accountant and an attorney, and told your family this was the one. But some deals cannot be fixed with price, and the money you keep by not closing them is real money.

This week we walk through a medical spa that looked cheap, and show the three findings that killed it.

This is a composite deal built from transactions we have worked on. Names, locations, and figures are changed.

Business: Single-location medical spa. Injectables, laser hair removal and skin treatments, and body contouring.

Team: Two nurse injectors, two aestheticians, and a front desk. The owner is not a clinician.

Asking price: $850,000

Revenue (trailing twelve months): $1,420,000

SDE per the listing advisor: $310,000

Implied multiple: $850,000 ÷ $310,000 = 2.74x SDE ✓

Recent trend: revenue up 40.7% in the last six months versus the six before

The buyer: a former regional manager for a fitness chain. Not a clinician. He planned to run the business and keep the clinical team.

A growing business at under 3x earnings. He signed an LOI with 45 days of exclusivity and hired an accountant and a healthcare attorney.

On the listing's numbers, the loan was easy.

Price $850,000 + closing costs $30,000 + working capital $40,000 = project cost $920,000

Buyer down payment (10%): $92,000

SBA loan: $828,000 over 10 years at an illustrative 9.75% (Prime plus 2.75%)

Annual debt service (exact monthly payment x 12): $129,933 ✓

Listed SDE less a $70,000 salary for the buyer, divided by debt service: 1.85x ✓, well above the 1.25x SBA floor.

This deal was built from cash-basis books. Cash-basis books show the cash that came in. They do not show who is still owed services for that cash. That is the buyer's job to find.

The accountant pulled the package and membership ledger from the booking software. Every prepaid package, banked membership credit, and gift card is a service the spa has been paid for and has not delivered yet.

Unused packages: $255,000

Banked membership credits: $50,000

Gift cards: $25,000

Prepaid services owed: $330,000 ✓

Six months earlier, the balance was $140,000. It grew by $190,000 ✓ during the promotion.

A buyer inherits that list of clients. They will book, and they will expect their treatments. At normal volume, $330,000 is about 3.4 months of the spa's revenue.

Product and provider pay run about 45% of each service dollar here, so delivering it costs at least $148,500 ✓ in cash. If those visits push out full-price clients, the real cost is closer to the full $330,000.

Medical spa diligence guides flag this exact item. Prepaid packages, memberships, and gift cards should be restated from cash to accrual, and the liability belongs in the working capital target.

Why did revenue jump? Six months ago, the owner started selling treatment packages at 35% off menu.

Package and membership sales went from $70,000 in the first half of the year to $310,000 in the second.

Cash revenue, last six months: $830,000

Less cash for services not yet delivered: ($190,000)

Revenue actually earned, last six months: $640,000 ✓

That is growth of 8.5%, not 40.7%. And it came at 35% off.

Earnings tell the same story. Before the promotion, the spa earned $98,000 of SDE in six months. During the promotion, on an accrual basis, it earned $22,000. The discount gave away almost all of the margin.

Nobody knows how many promotion clients will come back at full price. The buyer would be paying for revenue that may not repeat.

This one ended the deal.

The medical director lived about four hours away and was paid $1,000 a month. The attorney found:

Medical spa rules vary widely by state: who can own the practice, who can inject, what has to be ordered by whom, and what level of supervision is required. The attorney's view was that this arrangement likely did not meet the state's requirements.

Regulators are paying attention. A 2026 law firm review of medical spa enforcement described states directly targeting "ghost" and "matchmaker" medical director arrangements, where a physician signs a contract but provides no real oversight. In New York, state and city agencies inspected more than 200 medical spas and cited 87 for possible violations, including the unlawful practice of medicine.

Fixing it going forward was possible. A medical director who reviews charts and visits on site was quoted at $4,500 a month. That adds $42,000 ✓ a year of cost.

Fixing it backward was not. A purchase agreement can put pre-closing liability on the seller. It cannot stop a board complaint or an unhappy patient from landing at the clinic the buyer now runs. And because the buyer is not a clinician, his attorney said the ownership structure itself would need to be reviewed under the state's corporate practice of medicine rules before closing.

SDE per listing advisor (cash basis): $310,000

Cash collected for services not yet delivered: ($190,000)

Promotion months replaced with the pre-promotion run rate: $76,000

Compliant medical director: ($42,000)

Real SDE: $154,000 ✓

That is half of what was listed. At the asking price, he would pay $850,000 ÷ $154,000 = 5.52x real earnings ✓.

And the loan stops working. After his $70,000 salary, $84,000 is left for debt service of $129,933. Coverage: 0.65x ✓.

The buyer's team worked backward from what the earnings could carry.

At 1.25x coverage, $84,000 supports $67,200 a year of debt service. On the same 10-year loan terms, that is a loan of $428,232. Add a 10% down payment and take out the same $70,000 of closing costs and working capital, and the price is $405,813 ✓.

Then take off the $148,500 cost to deliver the services owed.

The most the business could support: $257,313 ✓

The seller's lowest counter was $700,000. That is $442,687 ✓ apart. The seller also owed $185,000 on his laser equipment, so at $257,313 he would walk away with $72,313 before fees and taxes. He was never going to accept that.

Even if he had, the medical director problem was not a price problem. It was a legal problem with an unknown cost. You cannot discount a number you cannot measure.

The buyer spent $16,500 on the accountant and the attorney, 1.9% of the asking price.

Here is what closing at $850,000 would have cost him:

Down payment: $92,000

Year one shortfall: $84,000 of cash flow, less $129,933 of loan payments, less $148,500 to deliver the services owed = ($194,433)

Cash at risk in year one: $286,433 ✓

That is before any regulatory issue. And it means paying $592,687 ✓ more than the business could support, on a 10-year loan with a personal guarantee.

He did not lose a deal. He spent $16,500 to avoid putting $286,433 at risk in year one alone.

Every problem here was in the seller's own systems. The package ledger was in the booking software. The promotion was on the spa's own website. The medical director agreement was in a drawer.

The listing showed growth. Diligence showed a discount, a liability, and a compliance gap. Walking away was not a failure of the search. It was the diligence working.

This spa was easy to find. Strong revenue, a growing trend, and a price under 3x earnings.

Deal sourcing is the easiest part of buying a business. Due diligence is where you find out what you are actually buying, and sometimes that you should not buy it at all. That is the work we do every day.
