How to Buy a Business: A Comprehensive Guide
A step-by-step guide to buying a business, from setting your budget to closing: SBA financing, due diligence, and what to check before you offer.


Buying a business can be one of the best financial moves a person makes, or one of the worst. The difference usually comes down to preparation and discipline.
A lot of people are drawn to it right now — corporate professionals wanting out, investors looking for cash flow, entrepreneurs who would rather buy than build. With a historic wave of owners retiring, there is more to choose from than ever.
The short answer
Work out what you can afford, get pre-qualified for financing before you start looking, search confidentially through brokers and marketplaces, evaluate earnings and revenue, offer via a Letter of Intent, then verify everything in due diligence before closing. Many first-time buyers finance with an SBA loan requiring at least 10% down.
Why buy instead of start
Buying an existing business means buying something that already works: existing customers, revenue, employees, and systems. You skip the brutal startup phase where most new businesses fail and step into cash flow from day one.
The tradeoff is that you pay for that track record, and you inherit the business as is, with room to change it, and enhance and modify as you see fit. Which is exactly why the process below matters.
Step 1: Work out what you want and can afford
Start with honest self-assessment. What kind of business fits your skills, your interests, and your life? A business depending on expertise you do not have is a hard place to start.
Then set your budget. Most first-time buyers finance with an SBA loan, which typically requires the buyer to place at least 10% down.
Step 2: Line up financing early
Serious buyers get pre-qualified before making offers, for two reasons:
- It tells you your real budget
- It makes you credible to sellers and brokers, who screen out buyers who cannot demonstrate they can close
A buyer with financing lined up gets taken more seriously, and advances quicker through the necessary steps to meet a seller. How that screening works is in the business sale process.
Talk to SBA lenders early and get a pre-qualification in hand. It is one of the highest-leverage things you can do.
Step 3: Find the right business
Businesses for sale are marketed confidentially, so you will see blind profiles first — industry, general location, and financials, without the name. You sign an NDA to learn more.
Opportunities come through business brokers, online marketplaces, and industry networks. Getting on a broker’s buyer list gives you access to vetted opportunities and someone who knows the market. Registering with advisors who represent sellers is one of the best ways to see quality deals early.
Step 4: Evaluate honestly, before you fall in love
Look at earnings — SDE or EBITDA — because earnings are what pay you back and service your loan. Revenue matters too, and the two move hand in hand. The distinction is explained in what is SDE.
Then ask the questions that actually determine value:
- Why is the owner selling?
- How dependent is the business on the owner? Will customers and knowledge transfer when they leave?
- Is there customer concentration that could sink the business if one client leaves?
- How stable are the earnings, and where does growth come from?
- What does the lease look like, and can it be assigned?
Step 5: Offer via a Letter of Intent
The LOI sets out your proposed price, structure, and major terms. Mostly non-binding, but it frames everything that follows.
Get the structure right, not just the price: how much cash at closing, whether the seller carries a note, any transition period, and the contingencies that protect you — satisfactory diligence and securing financing chief among them. We break it down in the letter of intent explained.
Step 6: Do your due diligence
Once the LOI is signed, you verify everything. For a buyer, this is your protection.
You and your accountant comb through the financials, confirm the earnings are real and documented, review contracts and the lease, and check legal and compliance history.
Step 7: Finalize financing and close
While diligence proceeds, you finalize the loan.
Once diligence is satisfied and financing approved, attorneys draft the purchase agreement and you close — sign, fund, and take ownership.
The mistakes that cost first-time buyers most
- Skipping pre-qualification. You waste months on businesses you cannot finance.
- Rushing diligence because you are emotionally committed.
