Collateral for a business loan includes real property, equipment, accounts receivable, inventory, and blanket business assets — lenders perfect their security interest by filing a UCC-1 financing statement. Unsecured products (revenue-based financing, some lines of credit) exist but carry higher costs.
Collateral is any asset a lender can claim and liquidate if a borrower defaults on the loan. The most common categories of business loan collateral are: (1) Real property — commercial real estate, including buildings, land, and fixtures; (2) Equipment and machinery — vehicles, manufacturing equipment, computer hardware, specialized tools; (3) Accounts receivable — outstanding invoices from creditworthy customers; (4) Inventory — finished goods and raw materials (typically advanced at 40–60% of liquidation value); (5) Cash and cash equivalents — certificates of deposit, savings accounts, investment accounts. Lenders perfect their security interest in personal (non-real property) collateral by filing a UCC-1 financing statement with the debtor's state secretary of state under Article 9 of the Uniform Commercial Code. Real property liens are perfected by recording a deed of trust or mortgage with the county recorder. The Federal Reserve's Survey of Terms of Business Lending (E.2) documents that secured loans represent the majority of commercial and industrial lending — collateral requirement is the norm, not the exception.
A blanket lien (also called a general lien) covers all present and future business assets — accounts receivable, equipment, inventory, cash, intellectual property, and other assets the business owns or acquires during the loan term. Blanket liens are standard for SBA 7(a) loans, revenue-based financing, and most alternative lender products. The SBA Standard Operating Procedure 50 10 requires SBA 7(a) lenders to take all available collateral up to the loan amount — including a blanket lien on business assets and, in many cases, a lien on the owner's personal real estate if business collateral is insufficient. A specific lien is tied to a defined asset — most commonly used in equipment financing (the lender takes a purchase money security interest in the specific equipment being financed) and real estate loans (the property deed of trust secures that specific property). Specific liens are more protective for borrowers because they limit lender claims to the collateralized asset rather than all business property.
Lenders do not advance 100% of an asset's stated value as collateral — they apply advance rates (also called loan-to-value ratios) that reflect the asset's likely liquidation value if the business defaults. Typical advance rates: real estate 70–80% of appraised value; equipment 60–80% of orderly liquidation value; accounts receivable 70–85% of eligible AR (lenders exclude invoices over 90 days, government AR, and related-party AR from the eligible pool); inventory 40–60% of cost value (more volatile and harder to liquidate than receivables or real estate). The total collateral value after applying advance rates is compared to the loan amount — loans where collateral coverage exceeds 100% of the loan amount are considered fully secured; loans where collateral falls short are considered under-secured, which raises the lender's risk and often the loan's cost. For SBA loans, SBA SOP 50 10 specifies that under-secured SBA 7(a) loans may still be approved if other underwriting factors (DSCR, credit, management experience) are strong.
Not all business financing requires explicit collateral. Unsecured products include: business credit cards (no specific collateral, though a personal guarantee is standard); short-term working capital loans from some alternative lenders; and unsecured business lines of credit (generally available only to established businesses with strong FICO and revenue). Secured products include: SBA 7(a) loans (collateral required per SOP), SBA 504 (real estate or equipment as collateral), equipment loans (the equipment itself), commercial real estate mortgages, and most bank term loans and lines of credit. Revenue-based financing and MCAs typically require a blanket UCC-1 on all business assets but do not require specific hard collateral appraisals — underwriting is based on daily cash flow, not collateral liquidation value. According to the Federal Reserve's 2023 Small Business Credit Survey, approximately 60% of small business loan applications included some form of collateral — with real estate and equipment as the most frequently pledged asset types.
Under SBA SOP 50 10, SBA 7(a) lenders are required to take all available collateral up to the loan amount — including business assets, real estate, and in many cases the owner's personal real estate. If your business cannot fully secure the loan through business assets, the lender will typically add the owner's personal residence as additional collateral. This is a structural feature of the SBA program, not an optional lender add-on.
