The Basics

What Is a Commercial Real Estate Loan?

A commercial real estate (CRE) loan is a mortgage secured by commercial property — office buildings, retail centers, warehouses, mixed-use properties, or the building where your business operates. Unlike residential mortgages, CRE loans are evaluated primarily on the income-generating potential of the property and the borrower's business financials.

Commercial mortgage terms differ significantly from home loans: shorter amortization periods, balloon payments, and stricter debt service coverage requirements are common. Understanding these mechanics helps you choose the right loan structure and negotiate better terms.

🏢

Owner-Occupied CRE

The business owns and operates from the property. SBA 504 loans are popular here — offering up to 90% financing with long fixed-rate terms.

Investment Property

Property purchased to generate rental income. Lenders underwrite based on Net Operating Income (NOI) and the property's ability to service the debt.

Construction & Bridge

Short-term financing for development or transitional properties. Higher rates, interest-only payments, and a clear exit strategy (refinance or sale) are expected.

How Commercial Loan Payments Are Calculated
M = P × [r(1+r)ⁿ] ÷ [(1+r)ⁿ − 1]

Where M = monthly payment, P = principal, r = monthly interest rate (annual rate ÷ 12), and n = total number of monthly payments. Commercial loans often amortize over 25 years but have a 5–10 year balloon — meaning the remaining principal is due at balloon maturity.

Loan Types Compared

Commercial Mortgage Loan Options

Not all commercial mortgages are structured the same. Here's how the most common programs compare for business borrowers:

Loan Type Max LTV Typical Term / Amort. Best For
SBA 504 Loan Up to 90% 10–25 yr fixed / 25 yr amort. Owner-occupied CRE; long-term fixed-rate financing
SBA 7(a) Real Estate Up to 85% 25 yr amort. Mixed-use or partial real estate purchase with working capital
Conventional Commercial Mortgage 65–75% 5–10 yr balloon / 20–25 yr amort. Investment properties; established businesses with strong DSCR
CMBS (Conduit) Loan Up to 75% 10 yr balloon / 25–30 yr amort. Larger stabilized investment properties; $2M+
Bridge / Hard Money Loan 60–70% 12–36 months, interest-only Transitional, value-add, or time-sensitive acquisitions
Land Loan 50–65% Varies; often 2–5 yr Raw land or lots; land can be used as collateral for development

DSCR is the key underwriting metric. Debt Service Coverage Ratio = Net Operating Income ÷ Annual Debt Service. Most lenders require a minimum DSCR of 1.25×, meaning the property generates 25% more income than needed to cover loan payments. Higher DSCR unlocks better rates and higher LTVs.

Collateral & Security

What Is Collateral in Commercial Lending?

Collateral is an asset pledged to a lender as security for a loan. If the borrower defaults, the lender can seize and sell the collateral to recover the outstanding balance. In commercial real estate lending, the property itself is typically the primary collateral — but lenders may also require additional security depending on LTV, DSCR, or borrower credit.

🏢

Commercial Real Estate

The most common CRE collateral. Lenders place a first-lien mortgage on the property.

🌍

Land

Raw or improved land can secure a loan, though LTVs are lower (50–65%) due to illiquidity.

⚙️

Equipment & Machinery

Used as supplemental collateral or as primary security in equipment loans.

📦

Accounts Receivable

Short-term business receivables can back working capital lines and invoice financing.

💰

Cash & Securities

Bank accounts or investment portfolios pledged as collateral — sometimes called "collateral-based lending."

🤝

Personal Guarantee

Owners with 20%+ stake are typically required to personally guarantee commercial loans.

What Is Cross-Collateralization?

Cross-collateralization occurs when multiple assets are pledged to secure a single loan — or when a single asset secures multiple loans. It is common with SBA loans, bank relationships, and portfolio lenders who hold multiple loans for the same borrower.

Cross-Collateralization: How It Works
Property A
$800K value
+
Property B
$500K value
→
Loan #1
$900K balance
Equipment
$150K value
→
Loan #2
$100K balance
+
Loan #3
$80K balance
Both loans may be secured by both properties — defaulting on one loan could put all collateral at risk.

Cross-collateralization is a double-edged sword. It can help you qualify for larger loans or better rates, but it also means that defaulting on one loan may allow the lender to seize assets securing your other loans — even if those loans are current. Always review cross-collateral clauses carefully before signing.

✅

Benefits

May unlock higher loan amounts, lower rates, or easier approval when individual assets don't fully qualify on their own.

⚠️

Risks

Defaulting on any one loan can trigger lender action across all cross-collateralized assets, even those with performing loans.

📋

Where It Appears

Common in SBA loans (especially when the same bank holds multiple SBA loans), bank relationships, and credit union portfolios.

How to Qualify

What Commercial Mortgage Lenders Look For

1

Debt Service Coverage Ratio (DSCR)

Most lenders require a minimum 1.25× DSCR. Net Operating Income must exceed annual debt payments by at least 25%. Investment properties are underwritten almost entirely on this metric.

2

Loan-to-Value (LTV)

Conventional commercial lenders cap LTV at 65–75%. SBA programs offer up to 90% for owner-occupied properties. Lower LTV = lower risk = better rates. You'll typically need an appraisal from a certified CRE appraiser.

3

Credit Score & Business Financials

Most commercial lenders want a 650+ personal credit score and 2+ years of business tax returns. Strong business revenue and profitability reduce the weight placed on the property's standalone income.

4

Property Type & Condition

Lenders categorize properties as Class A, B, or C based on age, condition, and location. Class A stabilized properties qualify for the best rates. Vacant or distressed properties typically require bridge financing first.

5

Down Payment & Reserves

Expect 20–35% down for conventional CRE loans. Lenders often require 6–12 months of loan payments held in reserve post-closing. SBA 504 reduces the down payment requirement to as low as 10%.

FAQ

Frequently Asked Questions

How do I calculate a commercial real estate loan payment?
Commercial loan payments are calculated using the standard amortization formula: M = P × [r(1+r)ⁿ] ÷ [(1+r)ⁿ − 1], where P is the loan principal, r is the monthly interest rate (annual rate divided by 12), and n is the total number of monthly payments. Use the calculator above to estimate your payment instantly, or ask your lender for a full amortization schedule.
What are current interest rates for commercial real estate loans?
Commercial real estate loan rates vary by property type, loan program, LTV, and borrower strength. Conventional commercial mortgages typically run 1–3% above comparable residential rates. SBA 504 fixed rates are set by the SBA and are often competitive with conventional loans. Bridge and hard money loans carry significantly higher rates — often 9–15%+ — due to short-term, higher-risk structures. Check with multiple lenders for current rate quotes.
What is cross-collateralization in a loan?
Cross-collateralization means that multiple assets secure one or more loans simultaneously. For example, a lender may require both your commercial building and your equipment to serve as collateral for a single loan. It can also mean that one asset secures multiple loans — so a default on any one loan could give the lender rights over all cross-collateralized assets. Always read your loan documents carefully for cross-collateral clauses.
Can you use land as collateral for a loan?
Yes. Raw land can be used as collateral for a loan, though lenders treat it as higher risk than improved or income-producing property. Expect lower LTVs — typically 50–65% of appraised value — and shorter terms. Land is less liquid than improved property, so lenders discount its collateral value accordingly. If you plan to develop the land, a construction loan that incorporates the land value may offer better terms.
What is a conventional commercial mortgage?
A conventional commercial mortgage is a non-government-backed loan made by a bank, credit union, or private lender, secured by commercial property. Unlike SBA loans, there are no government guarantees — lenders take on the full risk and therefore have stricter underwriting requirements. Conventional commercial mortgages typically require 25–35% down, a strong DSCR, and a balloon payment at 5–10 years even if the loan amortizes over 20–25 years.
What is collateral-based lending?
Collateral-based lending (also called asset-based lending) is a financing approach where loan approval is driven primarily by the value of the collateral rather than the borrower's cash flow or credit score. It's common for real estate investors, bridge loans, hard money lending, and equipment financing. The trade-off is that collateral-based loans often carry higher interest rates and shorter terms than income-underwritten loans.
