The SBA Loan Timeline for Buying a Business (What Nobody Tells You Until It's Too Late)

A buyer signs an LOI. Forty-five days of exclusivity. She feels good about the deal.

Then she calls a bank.

The loan officer tells her the process takes 60 to 90 days. She has 45. She asks if they can move faster. They say they'll try. They don't.

The exclusivity period expires. The seller gets another offer. The deal dies.

This happens more than it should. SBA financing is the most common way to buy a small business, and most buyers don't understand the timeline until they're already in a deal. By then, the math doesn't work.

Here's what the timeline actually looks like, what banks are evaluating, and the one thing that separates buyers who close on time from buyers who don't.

What an SBA 7(a) loan is

The SBA 7(a) loan is a government-backed loan that covers up to 90% of a small business acquisition. The SBA doesn't lend the money directly. It guarantees a portion of the loan, which reduces the bank's risk and allows them to lend to buyers who wouldn't qualify for conventional financing.

For a $1M acquisition, a typical structure looks like this:

• Buyer equity: $100,000 (10%)
• SBA 7(a) loan: $800,000 (80%)
• Seller note: $100,000 (10%)

The seller note is often required by the SBA as a signal that the seller has confidence in the business's future performance.

Maximum loan amount is $5M. Terms are typically 10 years for business acquisitions. Rates are variable, tied to the prime rate plus a spread, and currently run in the 10 to 12% range.

The full timeline

Here's what the process looks like from first lender contact to closing day.

Weeks 1 to 2: Lender selection and pre-qualification Before you apply anywhere, talk to three to five SBA lenders. Not to apply, but to understand their process, their timeline, and whether they've done deals like yours before. Some lenders specialize in certain industries or deal sizes. A lender who has never financed a service business acquisition will move slower than one who does it every month.

Ask directly: "How many business acquisition loans did you close last year?" A loan officer who has done 50 will catch problems earlier, move faster, and know which underwriting questions to anticipate. One who has done 5 will learn on your deal. The difference in timeline can be four to six weeks, which is the difference between closing and losing the deal.

Get a pre-qualification letter if possible. It's not a commitment, but it tells the seller and broker that you've been through a basic financial review and you're a credible buyer.

Weeks 2 to 4: Application and document collection Once you've selected a lender and signed an LOI, you submit a formal application. The document list is long. Expect to provide:

• Personal financial statement
• Three years of personal tax returns
• Resume or professional background summary
• Business plan or acquisition rationale
• Three years of business tax returns (from the seller)
• Current year-to-date financials
• Business debt schedule
• Lease agreement or real estate information
• Purchase agreement or LOI

Collecting these documents takes longer than most buyers expect, especially the seller's documents. Start asking for them before you sign the LOI.

Weeks 4 to 7: Underwriting The bank's underwriting team reviews everything. They'll do their own SDE calculation, their own DSCR analysis, and their own assessment of the business's value. Their numbers may differ from yours.

This is where most delays happen. The underwriter has questions. Documents are missing. The seller is slow to respond. Every back-and-forth adds days.

Week 7 to 8: Commitment letter If underwriting goes well, the bank issues a commitment letter. This is a conditional approval: the bank will fund the loan if certain conditions are met before closing. Common conditions include a business appraisal, environmental assessment (for real estate), and verification of the seller's representations.

Weeks 8 to 12: Closing preparation The commitment letter triggers a parallel set of tasks: the SBA appraisal, legal document preparation, title work, and final verification of conditions. This phase is largely out of your hands, but delays here are common.

Total timeline: 60 to 90 days for a smooth process. 90 to 120 days if anything goes wrong.

What banks actually look for

Banks evaluate three things: the buyer, the business, and the deal.

The buyer

Credit score is the first filter. Most SBA lenders want a minimum of 680. Above 700 is better. Below 650 and you'll struggle to find a lender. Check your score before you start the process, not after you sign an LOI.

Relevant experience matters. A bank is more comfortable lending to a buyer who has managed a similar business than one who hasn't. You don't need to have owned a business before, but you need to be able to explain why you're the right operator for this specific business.

Personal financial statement. The bank wants to see your full financial picture: assets, liabilities, income, and net worth. They're assessing whether you can personally guarantee the loan and whether you have the financial cushion to weather a rough first year.

The business

DSCR (Debt Service Coverage Ratio) is the key metric. The SBA minimum is 1.15x. Most lenders require 1.25x. DSCR measures whether the business generates enough cash flow to cover the annual loan payments.

If the business generates $400K in SDE and the annual debt service on your loan is $120K, the DSCR is 3.3x. Plenty of cushion. If the SDE is $150K and the debt service is $120K, the DSCR is 1.25x. Right at the minimum. One bad year and you're in trouble.

The bank will calculate DSCR using their own SDE reconstruction, not the seller's. Their number is often lower than the seller's.

Before you sign an LOI, run the DSCR calculation yourself using the tax return numbers, not the broker's adjusted P&L. If the deal barely clears 1.25x on the seller's numbers, it probably won't clear it on the bank's. Finding this out after you've signed an LOI and started due diligence is expensive. Finding it out before costs you nothing.

Two or more years of tax returns showing consistent profitability. A business with one good year and two mediocre ones is harder to finance than one with three consistent years.

The deal

The purchase price needs to be supported by an independent appraisal. If you're paying 4x SDE for a business that appraises at 3x, the bank will only lend against the appraised value. You'll need to cover the gap with more equity.

Asset purchases are preferred over stock purchases for SBA loans. They're cleaner from a liability perspective.

The thing that actually determines whether you close on time

Most buyers shop for the best interest rate. That's the wrong question.

The right question is: which lender can close fastest?

SBA lenders fall into two categories. Preferred Lender Program (PLP) lenders have been authorized by the SBA to approve loans in-house, without sending the application to the SBA for review. Non-PLP lenders have to submit every application to the SBA, which adds two to four weeks to the timeline.

A PLP lender can close in 60 days. A non-PLP lender often can't close in 90.

The difference between a 10.5% rate and a 10.75% rate on a $1M loan is about $2,500 per year. The difference between closing in 60 days and losing a deal because your financing took 90 is the entire acquisition.

Work with a PLP lender. Ask directly: "Are you a Preferred Lender Program lender?" If they hesitate or don't know, find someone else.

How to prepare before you have a deal

The buyers who close on time are the ones who started the financing process before they found a deal.

Before you sign your first LOI, you should have:

• Checked your credit score and resolved any issues
• Completed a personal financial statement in bank format
• Talked to two or three PLP lenders and gotten a pre-qualification
• Assembled your personal document package (tax returns, resume, financial statement)

When you sign an LOI and call your lender, you want to say "I'm ready to submit a full application today." Not "I need a few weeks to get my documents together."

The buyers who lose deals to slow financing are the ones who treated lender selection as a post-LOI task.

What kills SBA loans

A few things that end deals in underwriting:

Credit score below threshold. Discovered at application, not before. Check your score early.

Federal tax liens or outstanding SBA debt. The SBA will not guarantee a loan for a buyer who owes money to the federal government. This is a hard stop.

Prior bankruptcy within seven years. Disqualifying for most SBA lenders.

DSCR below 1.25x after the bank's SDE calculation. The bank's number is often lower than the seller's. If the deal is priced at the edge of what the cash flow supports, the bank's recalculation can push it below the threshold.

Business in a restricted industry. The SBA has a list of ineligible businesses: gambling, cannabis, lending, certain real estate activities. Check before you get deep into a deal.

Seller has existing SBA debt on the business. This complicates the transaction and sometimes kills it. Ask the broker early.

Non-U.S. citizenship. As of March 2026, SBA 7(a) loans require 100% U.S. citizen ownership. Green card holders and non-citizens are no longer eligible. If this applies to you, explore conventional bank financing or equity-heavy deal structures as alternatives.

---

The short version

SBA financing takes 60 to 90 days. Your LOI exclusivity period is typically 45 to 60 days. The math only works if you start early.

Talk to PLP lenders before you have a deal. Get pre-qualified. Assemble your documents. When you sign an LOI, you should be ready to submit a full application the same week.

The buyers who lose deals to slow financing didn't do anything wrong in the deal. They just started the financing process too late.
