Business Acquisition Financing Process: From LOI to Closing

Financing a business acquisition is not a single event. It is a multi-phase process that typically spans 60 to 120 days from letter of intent to closing, with each phase building on the one before it. Understanding this timeline and what lenders expect at each stage is the difference between a smooth close and a deal that falls apart at the last minute.

The business acquisition financing process follows a predictable sequence: pre-qualification, LOI execution, due diligence, loan application, underwriting, commitment, and closing. Each phase has specific deliverables, and delays at any stage can jeopardize the entire transaction. Sellers lose patience, competing buyers circle, and lender appetite can shift if market conditions change during an extended process.

This guide walks through every phase in detail, covering what borrowers need to prepare, what lenders evaluate, and where deals most commonly stall or fail. Whether you are pursuing an SBA-backed acquisition loan or a conventional term loan, the fundamental process follows the same arc, though SBA transactions layer additional compliance requirements onto each stage.

The acquisition financing process begins before the letter of intent is signed. Smart buyers engage lenders early, during the search phase, to establish borrowing capacity and identify potential deal-breakers before committing to a specific target.

Pre-Qualification

Pre-qualification involves presenting your financial profile to one or more lenders to determine approximate borrowing capacity. At this stage, lenders review:

• Personal financial statement - Net worth, liquid assets, and existing liabilities
• Credit history - Most acquisition lenders require a minimum credit score of 680 for conventional loans and 680+ for SBA loans
• Relevant industry experience - Lenders want operators, not passive investors
• Available equity injection - Typically 10% to 30% of the total project cost, depending on the loan program

Pre-qualification is not a commitment. It gives you a realistic range for deal size and signals to sellers and brokers that you are a serious, fundable buyer. Some lenders issue pre-qualification letters that can be included with your LOI to strengthen your offer.

Letter of Intent

The LOI establishes the basic deal terms: purchase price, proposed structure, due diligence period, exclusivity terms, and contingencies including financing. Key financing-related LOI provisions include:

• Financing contingency - Allows the buyer to exit without penalty if financing cannot be secured within a defined period (typically 45 to 90 days)
• Earnest money deposit - Usually 1% to 5% of the purchase price, held in escrow
• Seller financing component - If applicable, the LOI should specify the proposed seller financing terms (amount, rate, term, standby requirements)

SBA lenders often require that the LOI include specific language regarding the buyer's intent to use SBA financing, since SBA rules impose constraints on deal structure that affect the seller as well.

Once the LOI is executed, two parallel workstreams begin: buyer due diligence on the business and the formal loan application process. These run concurrently because lenders need the same information you are verifying.

Buyer Due Diligence

Due diligence is your opportunity to verify every claim the seller has made about the business. The standard due diligence period runs 30 to 60 days, though complex transactions may require extensions. Key diligence areas include:

• Financial verification - Three years of tax returns, interim financials, bank statements, AR/AP aging reports
• Adjusted EBITDA analysis - Identifying owner add-backs, one-time expenses, and non-recurring revenue to determine true cash flow
• Customer concentration - Lenders flag risk when any single customer exceeds 15% to 20% of revenue
• Legal review - Contracts, leases, litigation history, intellectual property, regulatory compliance
• Operational review - Staffing, systems, vendor relationships, and transition risks

Your financial statement preparation should begin during this phase if it has not already. Lenders expect clean, reconciled statements that align with tax returns.

Loan Application

The formal loan application package for an acquisition loan is substantially more complex than a standard business loan. A complete package typically includes:

1. Business plan - Covering the acquisition rationale, transition plan, growth strategy, and financial projections
2. Historical financials - Three years of target company tax returns plus interim statements
3. Buyer financials - Personal tax returns, personal financial statement, resume, and credit authorization
4. Purchase agreement or LOI - The signed deal terms
5. Collateral documentation - Asset lists, real estate appraisals, collateral valuation reports
6. Projections - Three-year financial projections showing debt service coverage at or above 1.25x

SBA acquisition loans require additional documentation including SBA Form 1919 (Borrower Information Form), the SBA-specific business plan format, and evidence that the buyer qualifies under SBA size standards. The SBA 7(a) program is the most common vehicle for acquisition financing under $5 million.

Underwriting is where the lender's credit team performs its independent analysis of the deal. This is the most opaque phase for borrowers, and where many deals stall without clear communication.

What Underwriters Evaluate

Acquisition loan underwriters focus on four primary areas:

• Historical cash flow adequacy - Can the business service the proposed debt based on trailing 12-month or three-year average performance? Lenders typically use the lower of the two periods.
• Transaction structure - Is the debt-to-equity ratio reasonable? Is there sufficient equity injection? Is seller financing on acceptable standby terms?
• Collateral coverage - What is the loan-to-value ratio on available collateral? Goodwill-heavy transactions (common in service businesses) present collateral gaps that lenders address through personal guarantees and SBA guaranty coverage.
• Borrower capacity - Does the buyer have the operational experience, financial reserves, and management ability to run the business and service the debt?

Common Underwriting Issues

The most frequent causes of underwriting delays or declines include:

• Cash flow shortfall - Projected DSCR below lender minimums, often caused by aggressive purchase price relative to earnings
• Unexplained financial inconsistencies - Discrepancies between tax returns and internal financials that suggest unreported income or overstated add-backs
• Industry risk - Certain industries face heightened scrutiny. Restaurant acquisitions, for example, carry higher failure rates that impact underwriting standards.
• Transition risk - Especially when the seller is the primary customer relationship holder or the business depends on the owner's personal expertise

Term Sheet and Commitment

If underwriting approves the deal, the lender issues a term sheet or commitment letter outlining final loan terms. Key terms to review carefully:

• Interest rate and structure - Fixed vs. variable rate, spread over prime or SOFR. Current acquisition loan rates vary by program and borrower profile.
• Amortization schedule - SBA 7(a) acquisition loans amortize up to 10 years for non-real estate transactions and up to 25 years when real estate is included
• Covenants - Minimum DSCR, maximum leverage, reporting requirements, and restrictions on distributions
• Closing conditions - Items that must be satisfied before funding, including appraisals, environmental reports, lease assignments, and regulatory approvals

Use the evaluating loan offers framework to compare commitment letters if you have received multiple offers. Focus on total cost of capital, covenant flexibility, and prepayment terms, not just the interest rate.

The period between commitment and closing is typically 15 to 30 days and is heavily administrative. Most of the substantive analysis is complete; the remaining work involves satisfying closing conditions and coordinating between multiple parties.

Pre-Closing Checklist

Common pre-closing requirements for acquisition financing include:

1. Business valuation or appraisal - SBA loans require an independent valuation for transactions over $250,000. Conventional lenders may have different thresholds.
2. Environmental review - Required for any transaction involving real estate, particularly Commercial Real Estate components
3. Lease assignment or new lease - If the business occupies leased space, the landlord must consent to assignment or issue a new lease to the buyer
4. Franchise approval - Franchise acquisitions require franchisor consent, which can add 30 to 60 days to the timeline
5. Insurance - Business insurance, key person life insurance (often required by lenders), and any specialized coverage
6. Title and lien searches - Confirming clean title on assets and identifying any existing UCC filings that must be released at closing
7. Subordination agreements - If seller financing is part of the structure, the seller's note must be subordinated to the senior lender's debt on terms acceptable to both parties

The Closing

Closing an acquisition loan involves significantly more documentation than a standard commercial loan. Expect to review and sign:

• Loan agreement and promissory note
• Security agreement and blanket lien documentation
• Personal guaranty (nearly universal in acquisition financing)
• Asset purchase agreement or stock purchase agreement
• Bill of sale, assignment, and assumption agreements
• Seller's note and subordination agreement (if applicable)
• Employment or consulting agreements (for seller transition)
• Non-compete agreements

SBA closings include additional SBA-specific forms and certifications. Total closing costs typically range from 2% to 5% of the loan amount, including SBA guaranty fees (which range from 0% to 3.75% depending on loan size and maturity), legal fees, appraisal costs, and title insurance.

Funding typically occurs at closing or within one to three business days. The purchase price is distributed according to the settlement statement, and you take operational control of the business.

The single biggest risk in acquisition financing is timeline slippage. Every additional week adds uncertainty, costs, and opportunities for the deal to unravel. Successful acquirers manage the process proactively rather than reacting to delays.

Timeline Acceleration Strategies

• Engage your lender before the LOI - Pre-qualification and informal deal review before you are on the clock saves weeks
• Prepare your borrower package in advance - Have personal financials, tax returns, and a business plan template ready before you start searching for targets
• Hire experienced professionals early - An attorney and CPA experienced in acquisition transactions prevent amateur mistakes that cause rework. Choosing the right lender is equally critical; a lender experienced in acquisition financing navigates underwriting faster than a generalist.
• Maintain parallel workstreams - Due diligence, loan application, and legal review should run simultaneously, not sequentially

Common Deal Killers

Understanding why deals fail helps you avoid the same traps:

• Insufficient equity - Buyers who cannot meet the equity injection requirement. SBA 7(a) acquisition loans typically require a minimum 10% equity injection, and lenders may require more for higher-risk transactions.
• Unrealistic valuation - Sellers pricing at 5x to 6x EBITDA for businesses that lenders will only finance at 3x to 4x. Your capital stack planning must account for the gap between seller expectations and lender limits.
• Seller unwillingness to cooperate - Sellers who restrict access to financials, employees, or customers during due diligence create underwriting problems
• Working capital surprises - Failure to account for post-closing working capital needs, which can leave the new owner cash-starved from day one. Managing working capital cycles is critical in the first 90 days of ownership.
• Lease risk - A landlord who refuses to assign or extend the lease can kill the entire deal if the location is essential to the business

Building contingency time into your LOI (request 90 days for financing rather than 60) and maintaining clear communication with your lender throughout the process are the two most effective risk mitigation strategies. Experienced borrowers also align their exit strategy with the financing structure from the outset, ensuring that the loan terms support their planned hold period and eventual disposition of the business.
