Business Loan Collateral: What Lenders Accept & When It's Required
Understanding collateral requirements is critical before applying for business financing. This guide covers the types of assets lenders accept, how they're valued, and what to do if you don't have collateral.

Quick Answer
Business loan collateral is an asset you pledge to secure a loan — if you default, the lender can seize it. Common forms include real estate, equipment, inventory, and accounts receivable. Most secured loans require collateral worth 80–100% of the loan amount, though SBA loans may require less. Unsecured loans (no collateral) are available but come with higher rates and stricter credit requirements.
Types of Collateral Lenders Accept
Lenders evaluate collateral based on how quickly and reliably it can be converted to cash in a default scenario. Each asset type carries different risk levels, which is reflected in its loan-to-value (LTV) ratio — the percentage of the asset's appraised value a lender will lend against.
Real Estate
Commercial property, owner-occupied buildings, and residential property (for SBA loans) are the most valuable collateral type. Real estate holds its value well and is easy to appraise, making it the preferred asset for large loans. Lenders typically require a professional appraisal and environmental assessment before accepting real estate.
Typical LTV: 80%
Equipment & Vehicles
Machinery, trucks, construction equipment, and manufacturing tools. Equipment financing is self-collateralizing — the purchased asset secures the loan. LTV depends on the asset's useful life and resale market. Specialized equipment with limited resale demand receives lower valuations than general-purpose machinery.
Typical LTV: 70–80%
Inventory
Raw materials, finished goods, and work-in-progress can all serve as collateral. LTV is lower because inventory value depends on market demand, perishability, and liquidation costs. Non-perishable, standardized products (e.g., electronics, building materials) receive higher valuations than seasonal or custom goods.
Typical LTV: 50–70%
Accounts Receivable
Outstanding invoices from creditworthy customers are commonly used in invoice factoring and asset-based lending. Invoices under 90 days old from established customers with strong credit receive the highest advance rates. Concentration risk (too many invoices from one customer) lowers valuation.
Typical LTV: 80–90%
How Lenders Value Collateral
Lenders never accept an asset at its full market value. They apply a loan-to-value (LTV) discount to account for the cost and uncertainty of liquidating a seized asset. Here's how the valuation process works:
1. Professional Appraisal
For real estate and high-value equipment, lenders require third-party appraisals. The appraiser determines fair market value (FMV) and forced liquidation value (FLV). Lenders typically lend against FLV, which is 60–80% of FMV.
2. LTV Ratio Application
The lender applies their LTV ratio to the appraised value. For example, if your commercial property is appraised at $500,000 and the lender uses an 80% LTV, you could secure up to $400,000 in financing against it.
3. Depreciation & Obsolescence
Equipment and vehicles lose value over time. A lender financing a 5-year-old CNC machine will discount its value more heavily than a new one. Technology-heavy assets depreciate faster than general-purpose machinery, leading to lower collateral values and shorter loan terms.
4. Lien Position
If another lender already holds a first lien on the asset, your new lender gets a subordinate (second) position. Second-lien holders face higher risk, so they offer less favorable terms or may decline the collateral entirely.
Collateral Requirements by Loan Type
| Loan Type | Collateral Required? | Typical Collateral | Personal Guarantee? |
|---|---|---|---|
| SBA 7(a) Over $25K | Usually Yes | Real estate, equipment, or blanket lien on business assets | Yes (20%+ owners) |
| SBA 504 Loans | Required | The purchased property or equipment itself | Yes |
| Bank Term Loans | Often Yes | Real estate, equipment, or general business assets | Usually |
| Online Term Loans | Often No | UCC lien on business assets (not specific collateral) | Sometimes |
| Equipment Financing | Equipment = Collateral | The financed equipment itself | Sometimes |
| Business Line of Credit | Depends | Inventory, AR, or unsecured for strong borrowers | Usually |
| Merchant Cash Advance | No | Future credit card sales (not traditional collateral) | Sometimes |
| Invoice Factoring | Invoices = Collateral | Outstanding accounts receivable | Rarely |
Unsecured Business Loans (No Collateral)
If you don't have assets to pledge — or prefer not to risk them — unsecured financing is an option. However, lenders offset the added risk with stricter requirements and higher costs.
Who Qualifies
- Personal credit score 680+ (700+ preferred)
- 2+ years in business
- Strong annual revenue ($250K+ for larger amounts)
- Positive cash flow and low existing debt
- Clean business credit history
Typical Terms
- Rates: 2–6% higher APR than secured equivalents
- Amounts: Usually capped at $250K–$500K
- Terms: Shorter repayment (1–5 years vs. 10–25 years)
- Speed: Faster approval (days vs. weeks)
- Guarantee: Personal guarantee still usually required
Common Unsecured Options
- Business credit cards — revolving credit up to $50K+, no collateral
- Online short-term loans — fast funding, but rates of 15–40% APR
- Merchant cash advances — repay from daily card sales, no fixed collateral
- SBA microloans up to $50K — competitive rates, flexible requirements
- Unsecured lines of credit — requires excellent credit and strong financials
Unsecured loans make sense when you have strong creditworthiness, need fast funding, or are borrowing a smaller amount where the rate premium is manageable. For borrowers with lower credit scores, secured loans typically remain the more accessible path.
Personal Guarantee vs. Business Collateral
Many borrowers confuse personal guarantees with business collateral. They're related but serve different purposes in the lending agreement.
Business Collateral
- Specific business assets pledged against the loan
- Lender can only seize the pledged asset(s) on default
- Limited to the asset's value — no further claim
- Common in equipment loans, SBA 504, and real estate financing
- Protects personal assets from the lender's reach
Personal Guarantee
- A legal promise that you personally will repay the debt
- Lender can pursue your personal assets (home, savings, etc.)
- Unlimited liability unless you negotiate a cap
- Required on most SBA loans for owners with 20%+ stake
- Even “unsecured” loans typically require one
Key takeaway: A loan can require both business collateral and a personal guarantee. SBA loans, for example, nearly always require a personal guarantee from any owner with 20% or more equity — even when business collateral fully covers the loan amount.
