Understanding Commercial Real Estate Investment Loans

Commercial real estate is a major asset class that provides significant investment opportunities for both individual and institutional investors. However, investing in commercial properties such as multifamily apartments, office buildings, retail centers, industrial warehouses, and other commercial spaces requires a substantial capital outlay. This is where commercial real estate investment loans come in – they enable investors to purchase income-producing properties using loan funds rather than their own cash.

An Introduction to Commercial Real Estate Lending

The commercial real estate lending industry involves various financial institutions that provide funding for all kinds of commercial property acquisitions and development projects. The major lenders include banks, life insurance companies, commercial mortgage-backed securities (CMBS) issuers, private equity firms, and government-sponsored entities like Fannie Mae and Freddie Mac.


Typically, commercial lending focuses on income-producing properties located in major metropolitan areas. The most commonly financed property types are multifamily, retail, office, industrial/warehouse, and hotel. Loan amounts can range anywhere from $1 million for smaller properties to $100 million or more for large portfolios and developments.

Commercial real estate lending is normally considered to be more complex than residential mortgages. This is because commercial properties are pretty much more expensive, generating cash flow is critical for debt repayment, and underlying risks are higher given fluctuations in commercial real estate values and lease rates over time. As a result, underwriting standards are more stringent, and non-recourse financing is less readily available compared to single-family home loans.


With the basics covered, let’s delve deeper into the main categories of commercial real estate investment loans available in today’s market.

Types of Commercial Real Estate Investment Loans

There are several major loan structures used for financing commercial property acquisitions and projects. Understanding the key differences between them can help investors identify the best options based on their specific deal characteristics and objectives.

Construction Loans

Construction loans are short-term loans utilized primarily for new development projects where the property does not yet generate income. They provide funding for land acquisition, design/engineering costs, site work, building construction, and other “hard costs.” Financing is typically disbursed in phases as the project progresses.


Construction loans generally have terms of 12-24 months and a “mini-perm” phase where the loan converts to permanent financing once construction is complete. Interest rates can be variable or fixed. Loan-to-cost ratios range from 70-80% depending on the lender’s risk assessment of the project and the developer’s experience/track record.

Bridge Loans

Bridge loans are short-term loans that “bridge the gap” between the purchase of an existing property and securing permanent financing. They are often used in sale-leaseback or portfolio transactions where temporary funding is needed prior to refinancing at a later date.

Bridge loan terms usually range from 6 months to 2 years with an interest-only payment structure. Financing is based on the property’s projected value once renovations, lease-ups, or other exit strategies are complete. Loan-to-value ratios are more conservative at 50-75% as they rely primarily on real estate collateral rather than stable cash flow.

Mini-Perm Loans

As mentioned earlier, mini-perm loans specifically refer to the transitional phase when a construction loan converts to permanent financing upon project completion. Interest rates and payment structures shift from variable to fixed at this stage. Mini-perms have terms like traditional permanent loans of 5-10 years, depending on the property type and amortization schedule.

They fill the gap between construction draws ending and the property reaching stabilized occupancy needed for a standard permanent loan. Underwriting focuses on lease status, projected rents at stabilization, property value based on market comparables, and the income approach.

Permanent Loans

Permanent loans, also known as term loans, provide long-term financing for income-producing commercial properties or refinancing existing properties. Terms range from 5-10 years for most property types, with fixed or floating interest rates and amortization periods of 20-30 years.

Underwriting criteria are rigorous and cash flow-dependent, requiring a detailed exit strategy/repayment analysis. Stabilized occupancy of 70-80% is expected, with strong, creditworthy tenants in place under long-term leases. Loan-to-value ratios for permanent loans average 60-70% based on income-based valuation models. Recourse is usually limited to 15% of the loan balance.

Mezzanine Debt

Mezzanine debt or “mezz” loans fill the gap between permanent senior debt and property owner equity on higher-leveraged deals. They are subordinate or junior to the primary commercial mortgage loan and provide additional leverage at 15-30% loan-to-value.

Mezz loans have shorter 3-5-year terms with fixed, variable, or hybrid interest rates. Amortization may be interest-only or amortized over the full term. However, the priority is yield/return for the mezzanine lender rather than long-term financing. Recourse is full, including carve-outs for fraud and misrepresentation.

This covers the major commercial real estate loan categories. In the following sections, we’ll explore underwriting standards, terms, and structures in more depth.

Commercial Real Estate Loan Underwriting Criteria

The commercial lending process involves extensive risk analysis by lenders to evaluate a property investment’s ability to service debt obligations from projected income streams. Key underwriting factors include:

Debt Service Coverage Ratio (DSCR)

Lenders require a minimum DSCR of 1.20-1.50x to ensure sufficient property net operating income (NOI) is generated to cover annual mortgage payments, including interest, principal, taxes, and insurance. If NOI is too low relative to debt payments, the loan will be declined.

Loan-To-Value (LTV) Ratio

Maximum LTV ratios range from 60-80% depending on the property type, location, strength of the sponsor, and risk profile. Less leverage is provided for projects with more uncertainty vs stabilized assets. Appraisals are commissioned to back LTV determinations.

Debt Yield %

Debt yield refers to the NOI divided by the loan principal amount, typically requiring a minimum of 7-10% to demonstrate cash flow is proportionate to the debt level supported.

Property Occupancy Level

Stabilized occupancy of 70-80%+ is expected for permanent financing. Construction/bridge loans may accept lower interim occupancy, but it impacts the loan amount approved.

Tenant Quality & Lease Terms

Creditworthiness, financial strength, and lease terms of major tenants are closely reviewed, favoring investment-grade companies under long-term NN leases. Short-term/percent rent leases elevate risk.

Sponsor/Borrower Experience & Financials

Strong sponsorship is key, requiring a proven track record of successfully developing/operating similar property types. Personal financial statements, and liquidity/credit history are assessed.

Location/Market Fundamentals

Loan approval hinges on a favorable supply/demand outlook, employment drivers, barriers to new competition in the submarket/MSA supporting sustainable property performance.

This sums up the major benchmarks and risk factors commercial lenders and their underwriters dig into when deciding whether to finance a real estate investment. Next, let’s explore common loan structures and terms.

Typical Commercial Real Estate Loan Structures & Terms

Loan structures and contractual terms can vary significantly between different lenders and transaction types. However, there are several standard features seen across many commercial lending programs:

Amortization Period

While full amortization is common for loans under $5 million, larger transactions often use partial interest-only periods of 3-5 years followed by a 25-30 year amortization schedule. This lowers early payments.

Loan Term

Term lengths are usually dictated by property type: 5-10 years for multifamily/office, 7-10 years for industrial, and 10-12 years for retail. Mezz loans are 3-5 years. Construction/bridge loans are short-term term as noted earlier.

Interest Rate Types

Fixed rates provide certainty but are higher, usually 100-200 basis points above comparable treasury rates. Floating rates like LIBOR +x% are more flexible/refinance-friendly if rates decline but introduce variability.

Prepayment Penalties

Most permanent loans allow prepayment after a defined lockout period (typically 2-5 years) subject to a declining penalty over 5-7 more years, then none. Construction/bridge loans may prohibit prepayment entirely.

Escrows for Taxes/Insurance

Monthly debt service includes escrow amounts lenders hold for annual insurance/property tax bills to avoid payment shortfalls from unplanned special assessments.


Upfront loans require funded tax/insurance escrows, plus additional reserves such as capital expenditures, lease-up shortfalls, debt service, etc. Mezz lenders also require pre-funded interest reserves to cover several months of interest payments.

For construction loans, additional reserves are typically required for things like contractor’s contingencies to guard against cost overruns. Loan documents will outline the specific reserve requirements that must be satisfied upfront and maintained throughout the loan term.

Loan Fees

Origination/application fees of 1-2% of the loan amount are assessed at closing along with other processing fees. There may also be annual fees of 0.25-0.50% paid periodically. Prepayment penalties apply, as previously mentioned.

Insurance Requirements

At a minimum, commercial property insurance is required for the replacement cost of buildings/improvements, along with business income/rental value insurance to cover losses. Lenders are added as additional insured/loss payees.

Financial Reporting

Borrowers provide annual audited financial statements as well as monthly/quarterly operating statements and rent rolls. Covenant compliance is monitored on an ongoing basis.

These cover many of the common structures and requirements seen across commercial real estate loans. In the next section, we’ll discuss the application and approval process.
