How to Refinance a Commercial Real Estate Loan: A Comprehensive Guide

How to Refinance a Commercial Real Estate Loan in 5 Key Steps

To refinance a commercial real estate loan, evaluate your property’s net operating income and equity, gather updated financial statements, compare lender options—including conventional and SBA 504 programs—and submit a formal application for lender underwriting.

Refinancing a commercial real estate property requires a structured, analytical approach. Unlike residential mortgages that rely heavily on automated underwriting and personal debt-to-income ratios, commercial real estate refinancing centers on the asset’s debt-service capacity, historical financial performance, and current market value. Whether our clients are approaching a scheduled balloon maturity, seeking to lower debt service, or looking to cash out accumulated equity for expansion, executing a successful refinance follows five distinct steps.

Overview: 5 Steps to Refinance Commercial Real Estate

1. Conduct a Financial Health Check: Calculate NOI, DSCR, and estimated LTV.
2. Assemble Underwriting Package: Gather tax returns, rent rolls, T12 P&Ls, and entity docs.
3. Select Loan Structure: Evaluate regional banks, national institutions, credit unions, or SBA loans.
4. Submit Application & Negotiate Terms: Review term sheets, interest rates, prepayment fees, and covenants.
5. Complete Due Diligence & Close: Complete commercial appraisal, Phase I ESA, title work, and legal closing.

Step 1: Conduct a Financial Health Check on the Asset

Before engaging lending institutions, we analyze the property’s financial position from an underwriter’s perspective. This initial assessment establishes baseline metrics that dictate loan sizing and eligible program structures.

• Net Operating Income (NOI): Calculate gross operating income (effective gross rent minus vacancy and credit loss) and subtract operating expenses. Operating expenses must include property management fees, real estate taxes, property insurance, utilities, repairs, maintenance, and administrative costs. Capital expenditures and existing debt service are excluded from NOI.
• Debt Service Coverage Ratio (DSCR): Determine current cash flow buffer by dividing net operating income by the annual principal and interest obligations of the proposed replacement loan. Learn how to calculate coverage with our DSCR calculation guide.
• Loan-to-Value (LTV) Ratio: Estimate current property value based on recent local sales comparables and cap rates. Divide proposed debt by estimated value to establish the baseline LTV ratio.

Step 2: Assemble a Comprehensive Underwriting Package

Lenders evaluate commercial real estate loan applications based on the completeness and accuracy of the submitted documentation. Missing or inconsistent financial schedules delay credit committee reviews and third-party report ordering. A standard documentation package includes:

• Three full years of business tax returns and audited or reviewed financial statements for the operating or borrowing entity.
• Three full years of personal federal tax returns and signed Personal Financial Statements (SBA Form 413 or standard lender format) for all principal guarantors holding a 20 percent or greater ownership interest.
• A trailing 12-month (T12) profit and loss statement alongside a current year-to-date income statement and balance sheet.
• A certified, detailed rent roll reflecting tenant names, unit numbers, square footages, monthly rent amounts, lease commencement and expiration dates, renewal options, and tenant expense recovery terms (triple net, modified gross, or full service).
• A detailed Schedule of Real Estate Owned (SREO) outlining current mortgages, monthly debt service, market values, and cash flows for all properties owned by principal guarantors.
• Entity documentation, including Articles of Organization, Operating Agreements, Corporate Resolutions, and Certificates of Good Standing.

Step 3: Evaluate and Select the Optimal Loan Structure

With property financials in order, we match the asset profile against appropriate capital sources. Financial institutions assess commercial real estate through different risk profiles, pricing models, and structural requirements. Capital providers typically fall into four distinct tiers:

1. Regional and Community Banks: Well-suited for stabilized assets with localized operating history. They offer portfolio lending flexibility, relationship pricing, and reasonable closing timelines, though they frequently require personal guarantees and deposit relationships.
2. National Banking Institutions: Offer competitive interest rates on institutional-grade assets in primary metropolitan markets, but enforce rigid underwriting criteria and conservative LTV thresholds.
3. Credit Unions: Frequently offer long-term fixed-rate options without aggressive prepayment structures, operating under distinct regulatory limits for commercial member business lending.
4. SBA Government-Backed Financing: The U.S. Small Business Administration’s 504 program provides specialized refinancing options for owner-occupied commercial properties, offering low down payments and long-term, fixed-rate debentures. Learn more about SBA 504 refinancing options.

Step 4: Formal Application Submission and Term Sheet Negotiation

Once target lenders are identified, we submit full underwriting files to obtain formal term sheets or letters of intent (LOI). This phase requires comparing key loan provisions beyond the initial interest rate:

• Fixed-rate terms versus variable-rate indices (such as the Secured Overnight Financing Rate [SOFR] or the Prime Rate) and margin spreads.
• Amortization schedules (typically 20 to 25 years for commercial real estate, or up to 25 years under the SBA 504 program).
• Prepayment penalty structures (yield maintenance, defeasance, or fixed step-down schedules like 5-4-3-2-1 percent).
• Ongoing covenant requirements, including minimum DSCR thresholds, liquid cash reserves, and annual financial reporting mandates.

Step 5: Navigate Underwriting, Third-Party Due Diligence, and Closing

After executing a term sheet and submitting a deposit for third-party reports, the loan transitions into formal credit underwriting. During this 30- to 60-day window, the lender orders third-party reports that verify the asset’s physical, environmental, and financial status:

• Commercial Appraisal: A certified general appraiser evaluates property value using income capitalization, sales comparison, and cost approaches. Read our detailed guide on the commercial appraisal process.
• Phase I Environmental Site Assessment (ESA): An environmental engineer reviews historical land usage to confirm the absence of recognized environmental conditions (RECs).
• Property Condition Report (PCR): On larger assets, an engineer assesses physical systems (roofing, HVAC, structural components) to establish mandatory capital reserve allocations.
• Title and Survey Review: Title attorneys confirm clear ownership, check for encumbrances, and issue an ALTA lender’s policy of title insurance alongside a current physical boundary survey.

Evaluating Key Commercial Underwriting Metrics

Commercial lenders evaluate financial risk through quantitative metrics that measure historical cash flow reliability, capital commitment, and loss-given-default potential. Understanding these calculations helps property owners structure debt effectively before entering underwriting.

Debt Service Coverage Ratio (DSCR)

The Debt Service Coverage Ratio measures the cash cushion available to cover annual principal and interest obligations. Underwriters calculate DSCR using net operating income derived from historical operational data, adjusting for non-recurring income or unverified expense reductions.

$$\text{DSCR} = \frac{\text{Net Operating Income (NOI)}}{\text{Annual Debt Service}}$$

For example, a retail strip center generating $250,000 in annual net operating income with proposed annual debt service of $192,000 achieves a DSCR of 1.30x:

$$\text{DSCR} = \frac{\$250,000}{\$192,000} = 1.30\text{x}$$

Most institutional and bank underwriters require a minimum DSCR of 1.25x on stabilized commercial properties. If an asset falls below this threshold during underwriting, lenders reduce the maximum loan amount until the required coverage level is reached—a process known as sizing down the loan.

Loan-to-Value (LTV) and Debt Yield Metrics

While DSCR measures ongoing cash flow coverage, Loan-to-Value (LTV) limits exposure relative to physical asset value. Standard conventional commercial refinancing programs cap LTV between 65 percent and 75 percent of appraised value. Underwriters calculate LTV as follows:

$$\text{LTV} = \frac{\text{Total Proposed Mortgage Balance}}{\text{Appraised Commercial Real Estate Value}}$$

In shifting rate environments, lenders increasingly rely on Debt Yield as a secondary sizing metric independent of interest rates and amortization periods. Debt yield measures the lender’s cash-on-cash return in the event of foreclosure:

$$\text{Debt Yield} = \frac{\text{Net Operating Income (NOI)}}{\text{Total Loan Amount}}$$

Lenders commonly look for minimum debt yields between 9.0 percent and 11.0 percent. If a property produces $180,000 in NOI, a lender enforcing a 10.0 percent minimum debt yield limits total financing to $1,800,000, regardless of a favorable appraisal or lower interest rates.

Global Cash Flow Analysis and Guarantor Requirements

For closely held real estate entities, underwriters look beyond the subject property’s performance to perform a global cash flow analysis. This evaluation combines the cash flow and debt obligations of all related business entities and principal guarantors.

Underwriters combine net income, depreciation, interest expense, and distributions across all operating companies and real estate investments, balancing these figures against total personal and corporate debt service obligations. Guarantors are typically required to maintain post-closing liquidity—in liquid funds or unencumbered market securities—equal to 6 to 12 months of total debt service across all entities, along with a total net worth equal to or exceeding the requested loan amount.

Comparing Commercial Refinancing Loan Programs

Selecting the right refinancing instrument depends on property type, occupancy profile, historical cash flows, and investor hold horizons. Below is a detailed breakdown of primary commercial refinancing programs.

Conventional Commercial Bank Financing

Conventional loans from commercial banks are the standard financing model for stabilized, income-producing properties including multi-tenant retail, industrial warehouses, professional office buildings, and multifamily projects. Banks hold these commercial mortgages on their balance sheets, evaluating localized market conditions and long-term borrower relationships.

Conventional commercial bank loans typically feature 5-year, 7-year, or 10-year fixed terms structured over a 20- or 25-year amortization schedule. Because these loans carry balloon payments upon term expiration, property owners must refinance or payoff the remaining balance at maturity. Pricing tracks Treasury yields plus a margin reflecting risk and creditworthiness.

SBA 504 Refinance Program for Owner-Occupied Real Estate

For operating business owners occupying at least 51 percent of the commercial property’s usable square footage, the U.S. Small Business Administration (SBA) 504 loan program offers long-term financing options. Administered through Certified Development Companies (CDCs), the 504 program allows businesses to refinance existing commercial real estate debt while preserving working capital.

The SBA 504 structure combines two loans:

• Senior Bank Loan: A conventional financial institution provides a first mortgage covering 50 percent of the total project value.
• Junior Debenture (SBA/CDC): A government-backed debenture covers up to 40 percent of the value, backed by a 100-percent federal guarantee.
• Borrower Equity: The owner provides a minimum of 10 percent equity (or existing property equity).

The 504 Refinance program offers two primary structures under standard regulations:

1. Debt Refinance Without Expansion: Refinances commercial property debt that is at least 6 months old, provided the existing loan was used for eligible fixed-asset costs (acquisition, construction, or improvement of land and buildings). The property must meet owner-occupancy thresholds, and the target refinancing must reduce debt payments or replace unsustainable terms, such as balloon maturities.
2. Debt Refinance With Expansion: Allows expanding small businesses to include existing commercial debt in a new SBA 504 package when adding physical square footage, constructing additional facilities, or purchasing major equipment.

Under the SBA 504 cash-out provisions, eligible business owners can also access equity to pay for eligible operating expenses, including business payroll, inventory, utilities, supplier payables, or routine maintenance, up to maximum combined LTV caps (typically capped at 85 percent LTV for cash-out structures).

Bridge and Private Refinancing Structures

When assets undergo significant repositioning, face high vacancy, require lease-up periods, or deal with tight balloon payoff deadlines, conventional lenders may hesitate due to DSCR constraints. In these scenarios, private or bridge refinancing serves as a short-term transition tool.

Bridge loans focus on current asset collateral value and future turnaround potential rather than historical debt coverage. Structured as 12- to 36-month interest-only facilities, bridge loans give owners the runway needed to stabilize operations, execute capital improvements, or re-tenant property prior to seeking long-term conventional or government-backed permanent debt.

Commercial Loan Program Comparison Table

Loan Program	Maximum LTV	Minimum DSCR	Typical Fixed Term	Amortization	Best Suited For
Conventional Bank	65% – 75%	1.25x – 1.35x	5, 7, or 10 Years	20 to 25 Years	Stabilized income properties; strong localized guarantor liquidity.
SBA 504 Refinance	Up to 90%	1.15x – 1.20x	10, 20, or 25 Years	25 Years (Fully Amortized)	Owner-occupied properties (51%+ occupancy); long-term fixed rate needs.
Bridge / Short-Term	60% – 70%	1.00x – 1.10x (or Interest-Only)	1 to 3 Years	Interest-Only	Value-add assets; vacant buildings; urgent balloon maturity resolutions.

Navigating Upcoming Balloon Maturities and Rate Adjustments

Commercial loan maturities require proactive planning. Unlike residential loans that fully amortize over 30 years, commercial mortgages typically carry 5-, 7-, or 10-year maturity terms with remaining principal due as a balloon payment. Waiting too long to manage a balloon date exposes property owners to unnecessary default risk and higher interest expenses.

The 6- to 12-Month Timeline Window

We advise property owners to begin the refinancing process 6 to 12 months before an existing note’s balloon date. This timeline provides adequate buffer for financial review, credit approvals, third-party reports, and potential underwriting adjustments.

Time Frame	Key Action Items
Month 12 to 9	Review current loan documents to confirm exact maturity dates, loan balance, and prepayment terms. Assemble T12 financial statements, tax returns, and current rent rolls. Calculate preliminary DSCR and LTV metrics.
Month 8 to 6	Engage lenders and advisors to evaluate financing options. Request term sheets across conventional, agency, and SBA formats. Select preferred lender and execute term sheet.
Month 5 to 3	Pay third-party expense deposits. Underwriters order appraisal, Phase I ESA, and property condition assessments. Submit supplementary legal and entity documentation.
Month 2 to 0	Appraisal and third-party reports finalized. Loan moves to credit committee approval. Closing counsel draws loan documents, calculates payoff demands, clears title requirements, and funds the loan.

Stress-Testing Cash Flow Against Higher Interest Rates

Interest rate fluctuations significantly impact commercial loan capacity. When replacing a low fixed-rate mortgage issued in a lower-rate market, property owners must stress-test their debt service capabilities against higher underlying rate benchmarks.

Consider an office building generating $300,000 in annual NOI with an existing $3,000,000 loan balance amortized over 25 years:

• Previous Rate (4.00%): Annual debt service = $190,020. Calculated DSCR = 1.58x. (Meets standard underwriting).
• Refinance Rate (7.00%): Annual debt service = $254,448. Calculated DSCR = 1.18x. (Fails standard 1.25x DSCR underwriting threshold).

In this example, the elevated interest rate reduces the DSCR below the lender’s required 1.25x minimum. Underwriters sizing this transaction will reduce the max principal balance to roughly $2,830,000 to maintain the mandatory 1.25x ratio. This leaves a $170,000 capital gap that the property owner must address at closing.

Strategies for Managing Capital Gaps (Cash-In Refinancing)

When property cash flows fail to support a full debt rollover under updated underwriting criteria, borrowers have three primary structural strategies to consider:

1. Cash-In Refinancing: The borrower injects additional equity at closing to pay down principal debt, reducing total annual leverage to meet mandatory DSCR guidelines.
2. SBA 504 Restructuring: For owner-occupied properties, transitioning from conventional financing to an SBA 504 structure can reduce equity shortfalls by expanding LTV capacity up to 90 percent, backed by long-term 25-year fixed debenture pricing.
3. Mezzanine or Subordinated Preferred Equity: Structured preferred equity or secondary subordinated loans bridge the gap between primary bank mortgage limits and total capital requirements, though senior lenders must explicitly allow secondary debt encumbrances via intercreditor agreements.

Understanding Costs Associated with Commercial Loan Refinancing

A successful commercial loan transaction requires evaluating closing costs and potential exit fees associated with paying off existing debt. Total refinancing soft and hard transaction costs typically range between 1.0 percent and 3.0 percent of the new loan amount. Learn more about breakdown details in our commercial refinancing fee guide.

Lender and Advisory Fees

Direct financing costs cover administration, underwriting, and loan issuance:

• Origination and Processing Fees: Lenders charge between 0.50 percent and 1.50 percent of the total loan balance to cover underwriting, internal credit management, and administrative setup.
• SBA Guarantee and CDC Fees: SBA 504 loans include government-mandated debenture fees and CDC setup charges, which are standardized and typically funded directly within the total loan structure rather than paid out-of-pocket.

Third-Party Reports and Professional Fees

Independent third-party reports are required to protect lender collateral integrity and confirm physical and environmental standing:

• Commercial Appraisal: Depending on asset size, single-tenant commercial property valuations typically cost between $3,000 and $5,000, while multi-tenant retail or complex industrial assets run $5,000 to $9,000+.
• Phase I Environmental Site Assessment (ESA): A standard Phase I site investigation ranges from $2,200 to $4,500. If recognized environmental conditions surface, a Phase II intrusive soil and groundwater analysis can add $7,000 to $20,000+ to upfront costs.
• Property Condition Assessment (PCA): Architectural and physical engineering reports cost between $2,500 and $6,000 for standard commercial assets.
• Legal and Title Expenses: Borrowers cover legal expenses for both lender’s closing counsel ($3,500 to $10,000+) and their own legal representation, alongside standard ALTA lender’s title insurance policies, escrow fees, and municipal recording taxes.

Prepayment Penalties on Existing Loans

Before initiating a refinance, we review the existing note’s prepayment penalty clauses to avoid unexpected exit costs:

• Defeasance: Common in commercial mortgage-backed securities (CMBS), defeasance replaces real estate collateral with a portfolio of government bonds that replicates remaining loan cash flows. Defeasance incurs substantial legal, accounting, and broker fees.
• Yield Maintenance: A interest-rate-differential calculation that ensures the lender yields the same return as if the borrower paid out the full loan term. Yield maintenance costs increase when interest rates drop below original contract rates.
• Fixed Step-Down Schedule: A declining percentage scale based on the year of payoff (e.g., 5% in Year 1, 4% in Year 2, 3% in Year 3, 2% in Year 4, 1% in Year 5). This is common in conventional commercial bank loans.

Frequently Asked Questions

What credit score do you need to refinance a commercial loan?

Most commercial real estate lenders look for a principal guarantor credit score of 680 or higher, with prime programs preferring scores of 720 or above. However, commercial underwriting places far greater emphasis on property net operating income and debt coverage ratios than on personal credit scores alone.

How much does it cost to refinance commercial real estate?

Total refinancing costs typically range between 1 percent and 3 percent of the total loan balance. Expense items include lender origination fees, commercial appraisals, title insurance, legal costs, and Phase I environmental site assessments. On a $2 million commercial mortgage, total closing expenses generally fall between $20,000 and $60,000.

Can you cash out refinance a commercial property?

Yes, cash-out refinancing is available for commercial real estate provided the property maintains adequate equity and satisfies lender DSCR requirements post-refinance. Programs such as the SBA 504 allow eligible business owners to cash out equity for business operating expenses, including inventory, payroll, equipment, and debt consolidation.

How long does it take to refinance a commercial property loan?

A standard commercial real estate refinance takes between 45 and 90 days from application to closing. The primary timeline drivers are third-party report turnarounds, such as commercial appraisals, property condition reports, and Phase I environmental site assessments, along with title commitment reviews and formal credit committee underwriting approvals.
