Finance Your General Contracting Acquisition with an SBA Loan
SBA 7(a) loans are one of the most effective tools for buying a licensed general contracting business — offering low down payments, long repayment terms, and flexible structures that work with project-based revenue models in the $1M–$5M revenue range.
Find SBA-Eligible General Contracting BusinessesSBA Overview for General Contracting Acquisitions
Acquiring a general contracting business presents unique financing challenges: project-based revenue creates lumpy cash flow, EBITDA margins of 10–20% can be thin, and contingent liabilities from active projects require careful underwriting. SBA 7(a) loans are well-suited to this industry because they allow lenders to finance goodwill, working capital, and equipment in a single loan structure, while accommodating seller notes that help bridge valuation gaps. For buyers targeting licensed general contractors in the lower middle market, the SBA 7(a) program is typically the most accessible path to 80–90% leverage on the purchase price. Lenders experienced in construction acquisitions understand how to normalize EBITDA using job costing reports, how to assess backlog quality as a proxy for forward earnings, and how to structure deals that account for retainage, warranty holdbacks, and bonding continuity under new ownership. Expect total deal structures to combine an SBA 7(a) loan covering 75–85% of the purchase price, a buyer equity injection of 10–15%, and a seller note of 5–10% on standby for 24 months post-close.
Down payment: SBA guidelines require a minimum 10% equity injection for business acquisitions, but general contracting deals typically require 10–15% due to the goodwill-heavy nature of construction businesses and the elevated risk profile lenders assign to project-based revenue. On a $2.5M acquisition, that translates to $250,000–$375,000 in buyer equity at closing. Lenders will often allow a seller note of 5–10% of the purchase price to count toward the equity injection, provided it is placed on full standby — meaning no principal or interest payments — for at least 24 months post-close. Buyers should also budget for working capital reserves beyond the down payment, as general contracting businesses often require 60–90 days of operating capital to cover payroll, subcontractor payments, and material costs before project receivables are collected. Retainage balances — often 5–10% of contract value withheld until project completion — can further delay cash flow in the months immediately following closing.
SBA Loan Options
SBA 7(a) Standard Loan
10-year repayment for business acquisitions including goodwill; 25-year terms available if real estate is included; variable rates typically Prime plus 2.25%–2.75%
$5,000,000
Best for: Acquisitions of general contracting businesses where the purchase price includes goodwill, equipment, working capital, and active project backlog — the most commonly used structure for buying a licensed contractor in the $1M–$5M revenue range
SBA 7(a) Small Loan
10-year repayment; streamlined underwriting process with faster approval timelines; variable rates similar to standard 7(a)
$500,000
Best for: Smaller general contracting acquisitions where the total purchase price falls below $750,000, such as acquiring a sole-owner residential contractor with a small crew and limited equipment
SBA 504 Loan
10- or 25-year fixed-rate terms on the CDC portion; typically paired with a 50% conventional first mortgage from a bank lender
$5,500,000 combined (CDC portion up to $5M)
Best for: General contracting acquisitions that include the purchase of a commercial real estate yard, office building, or equipment-heavy operations — less commonly used for pure business acquisitions without a real estate component
SBA Express Loan
Revolving or term up to 10 years; faster SBA turnaround of 36 hours but lower maximum loan amount
$500,000
Best for: Buyers who need a bridge line of credit or working capital facility alongside a larger acquisition — useful for managing cash flow gaps during the transition period when retainage from pre-close projects is still being collected
Eligibility Requirements
- The business must be a U.S.-based for-profit general contracting company operating in a qualifying industry under SBA size standards — typically fewer than 500 employees for construction firms
- The buyer must demonstrate relevant construction industry experience, whether through prior ownership, project management, or field operations, as lenders treat key-man risk as a primary underwriting concern
- The acquired business must show at least two to three years of positive cash flow sufficient to service the proposed debt — lenders will normalize EBITDA using job costing reports and add-backs for owner compensation and personal expenses
- The general contractor license held by the seller must be transferable to the buyer or the buyer must qualify to obtain a new license in the applicable state before loan closing
- The buyer must inject a minimum of 10% of the total project cost as equity at closing — this may include a seller note on full standby, subject to lender approval
- The business must meet SBA affiliation rules, meaning the buyer cannot be controlled by or affiliated with another large contractor or entity that would push the combined size above SBA thresholds
Step-by-Step Process
Identify and Qualify a Target General Contracting Business
Source acquisition targets through business brokers specializing in construction, direct outreach to owner-operators aged 55–70 approaching retirement, or industry networks. Confirm the business generates $1M–$5M in revenue with 10–20% EBITDA margins, holds a transferable general contractor license, maintains bonding capacity, and has a diversified project backlog with documented contracts. Request three years of tax returns, P&L statements with job costing detail, and a current backlog report before signing an LOI.
Conduct Preliminary Due Diligence and Sign an LOI
Perform a high-level review of financials, license status, bonding history, accounts receivable aging, and retainage balances. Assess owner dependency by evaluating how many client and subcontractor relationships are personally held by the seller. Confirm no open mechanic's liens, active litigation, or unresolved warranty claims exist on completed projects. Sign a letter of intent that includes a purchase price, deal structure, working capital peg, and a holdback for warranty and retainage contingencies.
Select an SBA Lender with Construction Acquisition Experience
Approach SBA Preferred Lender Program (PLP) lenders or community development financial institutions with demonstrated experience financing construction business acquisitions. Provide the lender with three years of business tax returns, interim financials, the LOI, a business plan, your personal financial statement, and your construction industry resume. Lenders will scrutinize backlog quality, license transferability, and how EBITDA was normalized — work with your accountant to prepare a clear add-back schedule using job costing reports.
Complete Full Due Diligence and SBA Underwriting
Engage a CPA to review job costing records, billing-in-excess versus costs-in-excess positions, and percentage-of-completion accounting. Have an attorney review all active contracts, subcontractor agreements, insurance policies — including completed operations tail coverage — and the general contractor license transfer process in the applicable state. The SBA lender will order a business valuation, review the seller's three-year tax returns, and conduct a site visit. Resolve any open liens, warranty disputes, or bonding questions during this phase.
Finalize Loan Approval and Deal Structure
Work with your lender to finalize the SBA 7(a) loan commitment, confirm the seller note is structured on full standby, and negotiate the asset purchase agreement with your attorney. Establish a working capital peg tied to accounts receivable and accounts payable at closing. Confirm bonding continuity with the surety company and ensure the buyer's name or entity is added to the contractor's license before closing. Agree on a transition plan with the seller covering a 3–12 month consulting period, client introduction meetings, and subcontractor relationship handoffs.
Close the Transaction and Execute the Transition Plan
Fund the SBA loan, inject buyer equity, execute the asset or stock purchase agreement, and transfer the general contractor license and bonding to the new ownership entity. Notify key clients, subcontractors, and suppliers of the ownership change per the agreed communication plan. Begin the seller's transition consulting period immediately to protect existing project relationships and backlog conversion. Establish reporting systems for job costing, backlog tracking, and cash flow forecasting within the first 90 days post-close.
Common Mistakes
- ✗Failing to verify that the general contractor license is transferable to the new owner or entity before closing — some states require the buyer to pass licensing exams or meet experience requirements that can delay or prevent closing
- ✗Underestimating working capital needs post-close by not accounting for retainage balances, slow-paying project owners, and the gap between subcontractor payment obligations and receivable collection cycles
- ✗Normalizing EBITDA without job costing support — presenting add-backs to an SBA lender without project-level financial documentation leads to underwriting pushback and delayed approvals
- ✗Ignoring bonding continuity risk — failing to engage the surety company early in the process can result in existing performance and payment bonds being pulled at closing, halting active projects and damaging client relationships
- ✗Skipping a thorough review of completed operations insurance and warranty exposure — undisclosed defect claims or unresolved punch list items on recently completed projects can become significant liabilities within the first 12 months of ownership
Lender Tips
- Work exclusively with SBA Preferred Lender Program lenders who have closed construction business acquisitions — general underwriters unfamiliar with job costing, retainage, and percentage-of-completion accounting will struggle to properly underwrite a contracting business
- Prepare a detailed EBITDA normalization schedule supported by three years of job costing reports before approaching any lender — this is the single most important document for establishing earnings quality in a project-based business
- Clearly document the license transfer plan and bonding strategy in your loan application package — lenders treating these as unresolved risks will condition approval or reduce loan proceeds
- Structure a seller note of 5–10% on full standby to reduce the effective cash equity required and demonstrate seller confidence in the business — this is a standard and accepted practice for SBA construction acquisitions
- Request a working capital line of credit alongside the acquisition loan — managing cash flow during the first 6–12 months of ownership is the most common operational challenge in general contracting acquisitions, and having a credit facility in place before closing is far easier than obtaining one post-acquisition

Frequently Asked Questions
Can I use an SBA loan to buy a general contracting business if I don't currently hold a contractor's license?
Yes, but you must have a clear plan to obtain licensure before or immediately after closing. Many states require the qualifying individual — often called the Responsible Managing Officer or Responsible Managing Employee — to hold an active license. Some states allow a grace period for the new owner to qualify, while others require the license to transfer on the day of closing. Your SBA lender will require confirmation of licensure continuity as a condition of loan approval, so engage a construction attorney in your state early in the process to map out the exact requirements and timeline.
How do SBA lenders evaluate a general contracting business when revenue is project-based and inconsistent year to year?
SBA lenders underwriting construction acquisitions focus on three-year average EBITDA normalized using job costing reports, add-backs for owner compensation and personal expenses, and an assessment of forward-looking backlog quality. A strong current backlog with signed contracts, defined payment schedules, and diversified clients can meaningfully support the underwriting even if historical revenue shows year-to-year fluctuation. Lenders will also review billing-in-excess versus costs-in-excess positions to assess whether reported profits are supported by actual project economics.
What happens to the seller's bonding capacity when I acquire the business?
Bonding is tied to the individual or entity holding the surety relationship — not the business itself. When ownership changes, the surety company must underwrite the new owner and entity before extending or transferring existing bonds. Buyers should engage the seller's surety broker early in the acquisition process to understand what financial documentation, net worth, and experience credentials are required to maintain bonding capacity. On active projects with performance or payment bonds in place, failure to secure a smooth bonding transition can trigger project owner concerns and potentially jeopardize contracts mid-close.
Can seller financing be combined with an SBA 7(a) loan in a general contracting acquisition?
Yes, and it is a common structure in lower middle market construction deals. SBA guidelines allow seller notes to be counted toward the buyer's equity injection, provided the note is placed on full standby — meaning no principal or interest payments — for at least 24 months post-close. A typical structure in this industry might involve an SBA 7(a) loan covering 80–85% of the purchase price, a buyer equity injection of 10%, and a seller note of 5–10% on standby. This structure reduces the cash required at closing while giving the lender confidence that the seller has skin in the game post-close.
How should I handle active projects and retainage balances in the SBA loan deal structure?
Retainage — typically 5–10% of contract value withheld by the project owner until completion — is a significant balance sheet item in general contracting acquisitions. Buyers should negotiate a working capital peg in the purchase agreement that accounts for retainage receivables and defines which party is entitled to collect retainage on pre-close projects. A holdback of 3–5% of the purchase price held in escrow for 6–12 months post-close is a common mechanism to protect against retainage disputes, punch list claims, and warranty obligations arising from projects completed before the sale. Your SBA lender will want to understand how these items are treated in the deal structure before issuing a final commitment.
What EBITDA multiple should I expect to pay for a general contracting business, and how does that affect SBA loan sizing?
General contracting businesses in the $1M–$5M revenue range typically trade at 2.5x–4.5x EBITDA depending on backlog quality, client diversification, management depth, bonding capacity, and license transferability. A business generating $400,000 in normalized EBITDA might be valued at $1M–$1.8M. At those purchase prices, an SBA 7(a) loan of $800,000–$1.5M combined with a 10–15% equity injection and a seller note is a workable structure. Higher multiples — closer to 4x or above — are typically justified only when the business has a tenured management team, documented recurring commercial clients, and a backlog that extends 12 or more months forward.
