How to buy a small business: what's different about Main Street deals

Published October 25, 2026 · Facts checked as of October 2026

Short answer

Buying a small owner-operated business (often called a Main Street deal) follows the same steps as any acquisition, with a few differences that change how you approach it: the earnings are measured as seller's discretionary earnings rather than EBITDA, financing usually comes through an SBA 7(a) loan, the business often depends heavily on the owner, and the books are frequently mixed with the owner's personal finances.

That means your diligence time goes mostly into verifying earnings and planning the owner's handover.

Most acquisition advice online is written for private equity deals or for people buying a startup. Small owner-run businesses are different animals. Here's what changes and how to adjust.

Four things that are different

Main Street reality	What it means for you	Where to read more
Priced on SDE, with the seller's add-backs	Most price risk sits in the add-backs. Rebuild SDE yourself.	Add-backs
Financed by SBA 7(a)	10% minimum equity, lender valuation, 1.25 coverage, 10-year term.	SBA 7(a)
Owner does key work	Plan the handover; budget for jobs you won't do.	Owner salary
Books mixed with personal finances	Use bank statements and tax returns, not just the P&L.	Personal expenses

Illustration of where the risk usually sits in a Main Street deal.

Worked example: a Main Street deal from listing to loan

Illustrative example, not a real business, rate or valuation

A residential cleaning company is listed at $480,000 with SDE of $190,000. The tax returns (Schedule C) show net profit of $128,000. The owner's draw isn't an expense on Schedule C, so it's already inside that profit. Add back $9,000 of depreciation, $3,000 of interest and $14,000 of documented personal vehicle costs, and SDE is $154,000, not $190,000; the other $36,000 was "cash jobs" and family phone bills with no records. On $154,000: you need $70,000 to live on and $6,000 a year for equipment, leaving $78,000 for debt. A $432,000 SBA loan (90% of $480,000) at an example 10.5% over 10 years costs about $70,000 a year, so coverage is $78,000 ÷ $70,000 = 1.11, under the 1.25 minimum for an initial acquisition. At this price, the deal doesn't work on the verified numbers. Either the price comes down, the structure changes (more equity, a standby seller note) or you walk. That's a normal outcome on Main Street, and finding it before the LOI saves weeks.

Run this before you make an offer. Lenders will.

What SBA rules mean for Main Street buyers

Most Main Street purchases are financed with SBA 7(a) loans under SOP 50 10 8.1. The essentials: at least 10% equity on an initial acquisition, which can't be waived; a business valuation prepared for the lender (from a credentialed appraiser, or for 7(a) Small and SBA Express loans with a business purchase price of $350,000 or less, potentially an internal valuation); debt service coverage of at least 1.25 on historical earnings; a 10-year maximum term on the business portion; no seller earnouts; and a seller who can consult for up to 24 months but not stay as an employee. Talk to two or three lenders before you start serious searching. See SBA 7(a) for acquisitions.

Red flags common in small deals

Add-backs without documents, especially "cash jobs" and family expenses.
The owner is the product: the main technician, salesperson or face of the business.
A short lease or a landlord who hasn't been asked.
One customer or referral source carrying a big share of revenue.
Books kept by the owner's relative with no outside accountant.
Equipment that's near the end of its life and priced as if it weren't.

Main Street vs mid-market, side by side

	Main Street (owner-operated)	Lower mid-market
Earnings measure	SDE	EBITDA after management
Typical buyer	Individual who'll run it	Search funds, PE, strategic buyers
Financing	SBA 7(a), seller notes	Bank debt, investors, SBA at the smaller end
Books	Tax returns, often cash basis	Reviewed or audited statements
Diligence	Buyer-led, proof of cash, CPA help	QoE, legal teams
Biggest risk	Owner dependence, unverified add-backs	Management, integration, debt load

If you're buying on Main Street, most mid-market advice (complex structures, management incentive plans, formal data rooms) won't apply. What will apply: rebuilding earnings from tax returns, checking deposits, and planning the owner's handover.

Worked example: the owner-dependence discount, in hours

Illustrative example, not market wages

An owner of a small sign shop works 55 hours a week: 20 on sales and estimating, 15 on design, 10 on production and 10 on bookkeeping and admin. If you'll take over sales and management yourself (30 hours), you still need someone for 15 hours of design and 10 of production. At $28 an hour plus 12% payroll costs for 25 hours a week, 50 weeks a year, that's about $39,200 a year. That cost comes out of the SDE you'd actually keep. Listing the owner's week by task is the simplest way to see how much of "the business" is really the owner.

A practical sequence

Decide what you can run and afford, and get pre-qualified by an SBA lender.
Screen listings fast: price ÷ SDE, owner dependence, lease, trend.
For the few that pass, check tax returns against bank deposits and rate the add-backs before making an offer.
Offer on verified earnings, with a valuation contingency and a real transition plan.
Do diligence focused on earnings, lease, staff and customers.
Close, then spend the first 90 days learning before changing.

Documents to ask for on any Main Street deal

Three years of business tax returns (Schedule C, 1065 or 1120-S) and authorization for IRS transcripts.
Monthly P&Ls for 24 months plus year to date, and the seller's add-back schedule with support.
Twelve to 24 months of bank statements for every business account.
Card processor statements and any platform payout reports.
Customer list with revenue by customer (names can come later), and any contracts.
Lease, equipment list, licences and permits.
Payroll records and a staff list with roles, pay and tenure.
A written description of what the owner does each week.

Questions to ask the seller

Why are you selling, and why now?
What would break first if you were away for a month?
Which add-backs can you document, and which are estimates?
Would you carry part of the price as a seller note?
How long will you stay to transition the business?
Has the landlord been told, and will they assign the lease?

Mistakes first-time Main Street buyers make

Falling for the business before checking the numbers. Do the tax returns and bank statements first, the site visit second.
Treating the seller's add-backs as facts. Each one needs a document.
Ignoring the lease. A short term or a landlord who won't consent can end a deal late.
Forgetting working capital. The price buys the business; you still need cash to run it.
Skipping the transition plan. Agree in writing how long the seller stays and what they do.
Not paying yourself in the model. If the deal only works when you work for free, it is a job you bought, not a business.

Each of these is cheap to avoid before you sign a letter of intent and expensive to fix after closing.

Frequently asked questions

What counts as a small business acquisition?

There's no single definition. 'Main Street' usually means owner-operated businesses priced on SDE, often financed with SBA loans; larger 'lower middle market' deals have management teams and are priced on EBITDA.

How much does it cost to buy a small business?

The price, plus at least 10% equity on the total project if using an SBA loan for an initial acquisition, plus legal, accounting, lender and diligence costs and working capital.

Do I need a broker to buy a small business?

No. Most listings already have a seller's broker. You need your own attorney, CPA and lender.

What's the biggest risk in small business deals?

Overpaying for earnings that don't hold up, and owner dependence: the business doing worse once the seller leaves.

Can I use an SBA 7(a) Small or Express loan to buy a small business?

Yes, under SBA's September 2026 technical update to SOP 50 10 8.1, 7(a) Small and SBA Express loans can finance changes of ownership, subject to Appendix 15. When the business purchase price is $350,000 or less, the lender may use an internal valuation. The full debt service coverage standards still apply.

How long does it take to buy a small business?

From starting a search to closing commonly takes many months; from signed LOI to closing is often two to four months for SBA-financed deals, longer when licences, a franchisor or a difficult lease are involved. The biggest variable is how quickly the seller produces documents.
