Why Revenue Doesn't Tell You Whether a Business Is a Good Acquisition

When somebody is selling an asset, they naturally want to show it in the best possible light. That isn't necessarily dishonest. It is simply part of selling. But as the buyer, your job is different. Your job is to determine what the investment actually produces.

I don't want to know what something could theoretically make under perfect circumstances. I want to know what it makes today.

What are customers actually paying? What are tenants actually paying? What are payroll and operating expenses? What does insurance cost? What are the taxes? What repairs or capital expenditures are likely? What debt comes with the acquisition? And after everything is paid: what is left for the owner?

Suppose a business generates $2 million in annual revenue. That sounds substantial. But imagine it requires $800,000 in payroll, $350,000 in materials, $200,000 in advertising, $150,000 in occupancy and utilities, and $200,000 in administrative and operating expenses. Suddenly the $2 million headline means much less.

And we still haven't discussed debt service, taxes, equipment replacement or unexpected expenses. That is why I don't fall in love with the top-line number. I want to understand the economics underneath it.

I use the same thinking when evaluating rental properties. A property may look like an incredible opportunity because someone offers seller financing, subject-to financing, a low interest rate or very little money down. Those terms can be valuable. But attractive financing cannot rescue an investment that fundamentally doesn't produce enough income.

Suppose the realistic market rent is $2,000 per month and the property's mortgage, taxes and insurance are $2,200. Taking the property with $5,000 down doesn't suddenly make it a good rental. Taking it with zero down doesn't make it a good rental either. You can buy a bad deal with no money down. It is still a bad deal. That is one of the easiest mistakes to make when people become excited about creative financing.

Another mistake is making the numbers work by changing the assumptions. If comparable properties are actually renting around $2,000, I don't want an analysis based on $2,500 simply because that makes the spreadsheet attractive. I would rather lose a deal on paper than buy one based on imaginary income.

When evaluating rental property, I prefer looking at multiple sources, actual comparable rentals and existing leases where available. The same principle applies to a business. Don't value it based on what the seller says a new owner could eventually produce. First understand what the business is producing now.

Price matters. But terms can matter just as much. A lower purchase price financed badly can produce a worse investment than a higher price financed intelligently.

Interest rate matters. Amortization matters. Down payment matters. Balloon payments matter. Interest-only periods matter. Existing debt matters. Seller financing can sometimes turn an otherwise difficult acquisition into an attractive one. But I still come back to the same question: what does the investment produce after the debt is paid?

One metric I like is cash-on-cash return. The concept is straightforward: how much cash did I actually invest, and how much annual cash flow does that invested cash produce?

If I invest $50,000 and the investment produces $10,000 of annual cash flow after operating expenses and debt service, that is a 20% annual cash-on-cash return. It doesn't tell you everything. You still need to consider risk, appreciation, taxes, capital expenditures and the quality of the underlying asset. But it forces you to connect the money invested with the money actually coming back.

I also separate appreciation from operating performance. Maybe a property will be worth substantially more in ten years. Maybe a business can double its revenue. Maybe a neighborhood will improve. All of those things are possible. But possibility doesn't pay this month's mortgage.

I would rather own an investment that works based on today's reasonable numbers and have appreciation become the bonus. If the entire investment depends upon a future event occurring exactly as predicted, I don't consider that dependable cash flow. That is speculation.

One of the biggest lessons I have learned from reviewing acquisitions is that you should not have to convince yourself that a deal works. When I find myself changing the rent assumption, ignoring an expense, assuming perfect occupancy or projecting aggressive future growth just to reach an acceptable return, the numbers are telling me something.

Sometimes the best investment decision is simply: no. There will always be another property. There will always be another business. There will always be another seller. Protecting capital gives you the ability to participate when the right opportunity appears.

Before getting excited about an acquisition, I want answers to a few basic questions. And most importantly: does the investment still make sense without optimistic assumptions? If the answer is yes, then I become interested. If the answer requires everything to go perfectly, I usually don't.

Revenue gets attention. Cash flow creates value. Financing can improve an acquisition. Good terms can reduce the amount of capital required. Growth can create enormous upside. But none of those things eliminate the need for basic economics.

I want an investment that makes sense based on realistic numbers. Not the seller's best-case scenario. Not my own excitement. Not what might happen someday. Real income. Real expenses. Real debt. Real cash flow.

Because at the end of the day, the purpose of buying an investment isn't simply to say you own something. It is to own something worth owning.
