If you have bought a home, you know the rhythm of a mortgage: document your income, let the lender check your debts, and repay over 15 or 30 years. Many first-time investors assume a commercial property loan works the same way with bigger numbers. It does not. Commercial real estate (CRE) loans are underwritten around the property’s ability to generate cash, use different ratios, and often come due long before they are paid off.
This guide compares commercial real estate loans vs home mortgages: how lenders evaluate income, how loan-to-value (LTV) limits work, how terms are structured, what balloon payments mean, how early payoff is handled, and what paperwork to expect.
Key takeaways
Home lenders focus on your debt-to-income ratio (DTI); commercial lenders focus on whether the property’s income covers its payments, measured by the debt service coverage ratio (DSCR).
Federal guidelines suggest different maximum LTV limits by property type.
Many commercial loans amortize over a longer period than their term, leaving a balloon payment at maturity.
Commercial prepayment terms can include defeasance or yield maintenance.
Recourse terms and documentation are usually more extensive for commercial loans.
How Lenders Underwrite: Property Income vs. Personal Income
The biggest difference is the source of repayment. A home mortgage is repaid from your paycheck; a CRE loan is usually expected to be repaid from the property itself.
DTI for home mortgages
For a home loan, the central affordability measure is your debt-to-income ratio. The Consumer Financial Protection Bureau (CFPB) defines DTI as all your monthly debt payments divided by your gross monthly income. In the CFPB’s example, someone paying $1,500 for a mortgage, $100 for an auto loan and $400 for other debts has $2,000 in monthly debt payments; with a gross monthly income of $6,000, that borrower’s DTI is 33 percent. The CFPB also notes that different loan products and lenders will have different DTI limits.
DSCR for commercial loans
Federal bank regulators describe commercial real estate loans as those for which the cash flow from the real estate is the primary source of repayment. That interagency guidance includes multifamily and nonfarm nonresidential loans where 50 percent or more of repayment comes from third-party, nonaffiliated rental income. The OCC similarly describes CRE lending as covering acquisition, development and construction financing and the financing of income-producing real estate.
Because the property is expected to pay the loan, lenders look at DSCR, which compares net operating income (income minus operating expenses, before debt payments) to annual loan payments:
DSCR = Net operating income ÷ Annual debt service
As a hypothetical illustration, a building that produces $150,000 in net operating income and carries $120,000 in annual loan payments has a DSCR of 1.25. A ratio below 1.0 means the property does not generate enough income to cover its own debt.
There is no single required DSCR. The interagency guidance says a bank’s CRE lending policies should set minimum standards for borrower net worth, property cash flow, and debt-service coverage for the property.
LTV and Down Payment
LTV is the loan amount divided by the property’s value. Both home and commercial lenders use it, but the guardrails differ. The FDIC’s examination manual summarizes the Interagency Guidelines for Real Estate Lending Policies, which suggest that a bank’s internal LTV limits should not exceed recommended supervisory limits such as:
65 percent for raw land
75 percent for land development
80 percent for commercial, multifamily and other nonresidential construction
85 percent for construction of a one-to-four family residence
85 percent for improved property
By contrast, the same FDIC section states that owner-occupied one-to-four family home loans have no suggested supervisory LTV limit, although for any such loan with an LTV of 90 percent or more at origination, the institution should require credit enhancement in the form of mortgage insurance or readily marketable collateral.
These are ceilings for bank policy, not targets, and the FDIC notes that loans meeting them should not automatically be considered sound. The interagency guidance adds that policies should address minimum requirements for initial investment and maintenance of hard equity by the borrower. Expect the required equity to depend on property type, lender policy and cash flow.
Rate and Term Structures
Homebuyers know the 30-year fixed-rate mortgage. Commercial financing is more varied: regulators encourage banks to track CRE loans by structure, such as fixed rate or adjustable, and by purpose, such as construction, short-term or permanent. Each can carry different pricing, terms and covenants.
Some government programs offer longer fixed-rate options for owner-users. The SBA’s 504 program provides long-term, fixed rate financing for major fixed assets, with 10-, 20- and 25-year maturity terms available. Rates are pegged to an increment above the 10-year Treasury rate, the maximum loan is $5.5 million, and the SBA notes 504 loans cannot be used for speculation or investment in rental real estate.
Amortization vs. Loan Term and Balloon Payments
What amortization means
Amortization is the schedule over which regular payments would fully repay the principal. The term (maturity) is how long the loan actually lasts. On a typical home mortgage, the two match.
Why commercial loans often differ
Commercial loans frequently separate the two. Payments may be calculated over 25 years while the loan matures much sooner, keeping payments lower but leaving principal due at maturity. In a hypothetical example, a $1,000,000 loan at 6.5 percent interest with a 25-year amortization has a monthly payment of roughly $6,752. If that loan has a 10-year term, about $775,000 of principal would still be owed at the end of year 10. That remaining amount is the balloon.
Balloon payment risk
The CFPB describes a balloon payment as a large, one-time payment at the end of the loan term. It notes that loans with balloon payments generally have shorter terms than traditional mortgages, ranging between 5 and 10 years compared with 15 to 30 years, and that a balloon payment is generally more than two times the loan’s average monthly payment. Balloon payments are not allowed in “Qualified Mortgages,” with limited exceptions.
The CFPB adds that you may be able to refinance before the balloon is due, but if the property’s value falls or your finances decline, you might not be able to. That risk applies to commercial owners too, so plan for maturity well in advance.
Prepayment Penalties, Defeasance and Yield Maintenance
On the residential side, the CFPB explains that a prepayment penalty is a fee that some lenders charge if you pay off all or part of your mortgage early. Not all mortgages have one, and when they do, it typically applies only if you pay off the entire balance within a specific number of years, usually three or five.
Commercial loans may use a wider range of provisions. In general terms:
Step-down fees charge a percentage of the balance that declines over time.
Yield maintenance compensates the lender for interest income lost to early repayment, using a formula tied to prevailing rates.
Defeasance substitutes securities that generate the remaining scheduled payments for the property as collateral, releasing the lien.
Lockout periods prohibit prepayment for a set time.
Terms vary widely. As the CFPB advises, read the fine print and understand exactly when a penalty applies and how much it could cost.
Recourse vs. Non-Recourse
A recourse loan lets the lender pursue the borrower or guarantor personally if a foreclosure sale does not cover the debt. A non-recourse loan generally limits the lender to the property. Many non-recourse commercial loans still include “carve-outs” that create personal liability for acts such as fraud or misapplication of funds.
Home mortgages are typically signed by the homeowners personally, and a lender’s rights after foreclosure depend on state law. For commercial loans, whether you sign a personal guarantee, and its scope, is often part of the negotiation.
What Documentation to Expect
A commercial loan file usually covers both the borrower and the property. Requirements vary, but borrowers commonly assemble:
Personal and business financial statements and tax returns for the borrowers and any guarantors
Property operating statements and a current rent roll, along with copies of major leases
A purchase contract or, for a refinance, existing loan documents
An appraisal and, often, environmental and property condition reports
Entity documents for the borrowing company, such as operating agreements or articles of organization
For commercial construction loans, the FDIC lists supporting documentation such as a recorded mortgage or deed of trust, a title insurance policy and/or title opinions, appropriate liability insurance and other coverages, land appraisals, and evidence that taxes have been paid.
FAQ
Is my credit score irrelevant for a commercial real estate loan?
No. The property’s income usually drives the analysis, but federal guidance says credit analysis should reflect both the borrower’s overall creditworthiness and project-specific considerations. Your credit history, net worth and experience can still matter.
Does a balloon payment mean I have to pay the full balance in cash?
The balance is due at maturity, but many borrowers plan to refinance or sell before then. The CFPB cautions that refinancing may not be possible if property values fall or your financial condition declines, so it is wise to plan for that scenario early.
Is a small apartment building a commercial or residential loan?
It depends on the number of units and the loan’s structure. Federal guidance includes multifamily loans in its CRE definition, while one-to-four family homes fall under residential standards. Ask which category applies, since it determines underwriting.
Conclusion
A mortgage lender asks whether your income can carry the payment. A commercial lender asks whether the property’s income can, then looks at you as additional support. That shift changes the ratios, equity, term structure, prepayment rules and paperwork. Before applying, use this checklist:
Calculate the property’s net operating income and DSCR using realistic rent and expense figures.
Confirm the LTV and equity the lender expects for your property type.
Ask whether the rate is fixed or adjustable and how long any fixed period lasts.
Compare the amortization period with the loan term and estimate the balloon balance.
Read the prepayment terms, including any defeasance, yield maintenance or lockout provisions.
Clarify whether the loan is recourse or non-recourse and what carve-outs or guarantees apply.
Gather financial statements, tax returns, rent rolls, leases and entity documents early.
