What is a commercial real estate loan?
Commercial real estate loans finance income-producing assets such as offices, retail buildings, warehouses, and other eligible business properties. The lender evaluates the property’s operating performance, tenant quality, collateral, and ownership team.
Banks, insurance companies, commercial mortgage-backed securities lenders, and private debt funds use different funding models. Some retain loans; others securitize them. The capital source affects pricing, recourse, documentation, and the flexibility to change or repay the loan.
The details that shape this financing
Lease income must be durable
Underwriting considers rent rolls, lease expirations, concessions, tenant credit, and reimbursed expenses. A fully leased building can still carry risk if a major lease expires near loan maturity.
NOI and loan sizing
The lender tests net operating income against debt service, leverage, and sometimes debt yield. A purchase price supported by optimistic future rents does not necessarily support the requested loan today.
Maturity and amortization differ
Payments may be calculated over a longer amortization period than the loan’s actual term. The remaining balance becomes a balloon at maturity, requiring repayment, sale, or a qualifying refinance.
What limits apply to this program?
Published agency limits, private-lender criteria, and illustrative calculations serve different purposes. The table identifies which kind of boundary applies, and what can change the result for a particular loan.
| Requirement | Limit or framework | How to interpret it |
|---|---|---|
| Loan size | Property economics and capital-source limits | There is no single commercial equivalent of the residential conforming cap. Sponsor, asset class, location, tenant risk, and requested structure all affect maximum debt. |
| Leverage and coverage | LTV, DSCR, and sometimes debt-yield constraints | A lender can require all tests to pass. Negotiating one test does not remove the other loan-sizing constraints. |
| Term versus amortization | A shorter maturity may use a longer payment schedule | A five-, seven-, or ten-year maturity can leave a balloon after payments calculated over a much longer period. The agreement establishes the actual dates. |
| Funding and recourse | Bank, life-company, CMBS, or private debt execution | Each has its own guarantees, property acceptance, servicing rights, reserves, and prepayment framework. |
Compare the structure, not just the rate
What the lender reviews
The review follows the selected program and the actual transaction. A strong result in one area does not remove the requirements in the others.

| 02 | Leases and tenant concentration |
| 03 | Sponsor financials and ownership documents |
| 04 | Appraisal and environmental and condition reports |
| 05 | Maturity, covenants, and prepayment structure |
How the requirements work in practice
Underwrite the leases, not just the rent total
Tenant credit, remaining term, renewal options, concessions, expense reimbursements, and termination rights affect income durability. A large rent roll can conceal concentration in one tenant or a lease rollover cluster that precedes loan maturity.
Expenses and leasing costs reduce available cash
Lenders can normalize insurance, taxes, management, repairs, tenant improvements, leasing commissions, and reserves. A lease structure describing costs as reimbursable does not ensure all amounts will actually be collected. Vacancy and downtime require a realistic allowance.
Environmental and legal review protect collateral quality
A Phase I environmental review, condition report, zoning analysis, survey, and title work can identify costs or restrictions not visible in the purchase price. Borrower liquidity and guarantees help address risks beyond the property’s current income.
How rates and financing costs are determined
Capital sources have different priorities
A bank may hold the loan, an insurance company may seek stable long-duration income, and a CMBS lender may originate for securitization. Private funds can finance transitional assets. These models produce different approaches to recourse, reporting, reserves, and property changes.
Fixed-rate pricing generally uses a benchmark and spread
The relevant Treasury or swap curve provides a funding benchmark, while the spread compensates for credit, liquidity, structure, and lender execution. A benchmark move can change an uncommitted offer before closing.
Floating-rate financing needs more than an index quote
SOFR or Prime plus a margin can also include a floor, an interest-rate cap requirement, and fees. A lender may test coverage at a stressed rate. The cheapest starting coupon can support less permanent debt if rates or required coverage rise.
See how the program changes the numbers
Each example states assumed values to show a specific calculation. Hypothetical rates and underwriting thresholds are not current offers, program promises, or approval estimates.
Three debt-sizing constraints
Assume a $5,000,000 property with $400,000 accepted annual NOI. At hypothetical 70% LTV, the ceiling is $3,500,000. At 1.25 DSCR and an 8% mortgage constant, it is $4,000,000. At a 10% debt-yield floor, it is also $4,000,000. The $3,500,000 leverage cap is tightest, before other requirements.
A refinance shortfall at maturity
Assume the loan matures at $3,000,000. If future underwriting supports only $2,700,000, the borrower must address a $300,000 gap plus closing costs through equity, a sale, or another acceptable solution. An extension is not assured by continued on-time payments alone.
Where the tradeoffs become important
Rate certainty does not remove refinance risk at maturity. Compare amortization, balloon balance, guarantees, reporting duties, cash-management triggers, and prepayment provisions alongside the stated rate.
The questions that change the financing plan
Why permanent loans can still have refinance risk
A commercial property may have stable cash flow while its loan matures before the amortization schedule ends. Repayment then depends on a sale, new debt, or owner capital. A fixed interest rate protects the coupon during the term, not the amount or availability of the next loan.
Loan covenants can change cash availability
Coverage tests, reserve funding, reporting, and cash-management provisions can affect distributions even when payments remain current. A tenant event or declining ratio may trigger additional controls. Model the cash that can actually be distributed under the documents rather than assuming every dollar above debt service is immediately available.
An early exit is a financing decision
Yield maintenance, defeasance, and step-down penalties can produce different results under changing rates. Selling the property does not necessarily waive the charge. A loan intended for a long-term hold may be poorly matched to a sponsor planning a rapid repositioning and sale.
From initial review to funding
Match the loan to the asset
Review ownership, property condition, income, and intended hold or exit.
Document and verify
Provide financials and property records, then complete valuation and other required reports.
Review and close
Resolve conditions and confirm maturity, guarantees, reserves, and prepayment terms before funding.
Commercial Real Estate Loans FAQs
Is a 25-year amortization a 25-year loan?
Not necessarily. The loan might mature earlier with a substantial balance still due.
What is defeasance?
A contractual process that substitutes qualifying securities for real estate collateral to support the required payments. Availability and cost depend on the documents.
Can I refinance before maturity?
Possibly, but prepayment terms and lender requirements can make an early exit expensive.
Can I use the seller’s NOI without adjustments?
The lender generally verifies and normalizes the figures. Taxes, insurance, vacancy, management, reserves, and nonrecurring income can change accepted NOI.
Does a signed lease prove the rent will continue?
No. Tenant credit, termination rights, collection history, expiration, concessions, and market conditions matter. A signed lease is evidence, not a guarantee.
What does a debt-yield requirement add?
It tests NOI relative to debt without relying on the note rate or amortization. A loan can pass DSCR at a low payment and still fail the lender’s debt-yield floor.
Can a loan be assumed by a buyer?
Only if the agreement and lender permit it and the buyer satisfies the conditions. Assumption fees, guarantees, and approval timing can affect the sale.
