A commercial loan underwriting checklist covers five groups of items: business and owner financials, credit and guarantor information, property and collateral reports, environmental and insurance documentation, and the legal paperwork that proves your entity exists and can borrow. Assembling all of it before you apply is the single biggest thing you can do to avoid weeks of back-and-forth with the lender. An incomplete submission is the most common reason a deal stalls.
What follows is what underwriters actually ask for, why they ask for it, and the thresholds they measure your file against.
Business and Owner Financial Documents
Tax returns anchor the package. Lenders generally want at least three years of federal returns for the business, filed on the form that matches the entity type: Form 1120 for C-corporations, Form 1120-S for S-corporations, and Form 1065 for partnerships.1Internal Revenue Service. Entities 4 Each principal owner also provides three years of personal returns (Form 1040 with all schedules) so the underwriter can see total household income.
Three years lets the analyst see the trend. One strong year does not answer whether revenue is growing, flat, or falling. From these returns the underwriter pulls the line items needed to calculate the Debt Service Coverage Ratio, which measures whether the business produces enough cash to cover its loan payments. Most conventional commercial products want a DSCR of at least 1.25, meaning income exceeds annual debt payments by 25 percent. Some lenders will stretch to 1.20 for strong borrowers or certain property types, but that is about the floor.
Tax returns go stale fast, so lenders also want current internal financials: a year-to-date profit and loss statement and a balance sheet, both dated within the last 90 days. If the internal numbers don’t reconcile with the tax returns, expect pointed questions or a denial.
Every principal with 20 percent or more ownership completes a Personal Financial Statement listing all personal assets and liabilities. For SBA-backed loans that form is SBA Form 413, which also requires spousal disclosure.2U.S. Small Business Administration. SBA Form 413 – Personal Financial Statement Conventional lenders use similar forms. The PFS tells the underwriter how much weight a personal guarantee actually carries. Leaving off a known liability reads as intentional and can kill a deal.
Round out the financial package with a business debt schedule listing every outstanding credit obligation: lender name, original loan amount, current balance, interest rate, and monthly payment. This feeds into a global cash flow analysis that consolidates income and debt across all related individuals and entities, so if you own more than one business or your spouse owns another, prepare to document all of them. K-1 forms matter here because they show actual distributions moving between entities and owners, which prevents the same dollar from being counted twice.
Credit and Personal Guarantees
Lenders pull personal credit for every guarantor and review business credit separately. For smaller commercial requests, some lenders run the file through the FICO Small Business Scoring Service, which blends personal credit, business credit, and financial statement data into a single score from 0 to 300. Scores below roughly 140 typically trigger automatic rejection; scores above 220 signal low risk and can earn better terms. The SBA no longer mandates SBSS prescreening for 7(a) small loans after an early-2026 sunset, but many lenders still use the model voluntarily.3U.S. Small Business Administration. Sunset of SBSS Score for 7a Small Loans
Expect to sign a full personal guarantee if you hold a controlling interest. NCUA guidance tells credit unions that those with a controlling interest should give full, joint and several personal guarantees, and any waiver must be documented with specific mitigating factors.4NCUA. Personal Guarantees – Examiners Guide Banks apply similar policies.
Property and Collateral Documents
When real estate secures the loan, the collateral gets its own file. For multi-tenant properties, start with a current rent roll listing every tenant, leased square footage, monthly rent, and lease expiration. The underwriter checks for concentration risk, upcoming vacancies, and below-market rents that could signal weak management. Copies of the actual leases are required so the rent roll can be verified. Break out operating expenses clearly, because the underwriter needs them to calculate Net Operating Income, which drives the DSCR. For acquisitions, include the signed purchase agreement to document price and timing.
Appraisal
Federal regulations require a formal appraisal by a state-certified appraiser for any commercial real estate transaction above $500,000.5eCFR. 12 CFR Part 323 – Appraisals Below that, many lenders still order one but may accept an evaluation instead. For larger or complex properties, lenders often want the appraiser to hold the MAI designation from the Appraisal Institute.6Appraisal Institute. Our Designations The appraisal also sets the Loan-to-Value ratio. Most commercial programs cap LTV at 75 to 80 percent, meaning you need 20 to 25 percent equity. Private lenders may hold at 65 to 70 percent, and some government-backed programs allow higher.
ALTA/NSPS Land Title Survey
Commercial mortgage lenders almost universally require an ALTA/NSPS Land Title Survey, which goes well beyond boundary lines to identify encroachments, easements, and utility access points. The survey lets the title insurer remove broad survey-related exceptions from the policy.7National Society of Professional Surveyors. 2026 ALTA/NSPS Standards When you order it, specify a “2026 ALTA/NSPS Land Title Survey” (the current standards took effect February 23, 2026) and ask the lender which optional Table A items it requires.
Title Insurance
A lender’s title insurance policy is required on virtually every commercial mortgage. It protects the lender against undisclosed liens, boundary disputes, and ownership claims missed in the title search.8Consumer Financial Protection Bureau. What Is Lenders Title Insurance The premium is a one-time charge at closing. An owner’s policy is separate and optional, though usually worth buying.
Capital Improvements
If you’ve put money into the property, document it. Receipts and contracts for roof replacements, HVAC upgrades, or parking lot work can support appraised value and show active management. Underwriters read deferred maintenance as a risk signal, so evidence of reinvestment helps.
Environmental Reports and Insurance
A Phase I Environmental Site Assessment is standard. An environmental professional reviews historical uses, regulatory records, and physically inspects the site to flag recognized environmental conditions. The Phase I involves no sampling.9United States Environmental Protection Agency. Assessing Brownfield Sites If it turns up evidence of contamination, the lender orders a Phase II with actual soil and groundwater sampling, typically $5,000 to $15,000 for straightforward sites and more for complex ones. Older or deteriorated buildings may also need a structural or engineering report.
On insurance, provide proof of property coverage and general liability naming the lender as additional insured or loss payee. Depending on the property, the lender may also require business interruption, umbrella, or specialty coverage. For any property in a Special Flood Hazard Area, flood insurance is mandatory. Federal law prohibits regulated lenders from making, increasing, or renewing a loan on improved real estate in a flood zone unless the property is insured for the loan term in an amount at least equal to the principal balance or the maximum available coverage, whichever is less.10Office of the Law Revision Counsel. 42 USC 4012a – Flood Insurance Purchase and Compliance Requirements and Escrow Accounts For nonresidential buildings, the maximum NFIP coverage is $500,000 for the building and $500,000 for contents.11Congress.gov. A Brief Introduction to the National Flood Insurance Program The lender orders a flood zone determination during underwriting to check whether this applies.
Organizational and Legal Documents
The lender has to confirm your entity is real and that the person signing has authority to bind it. Missing any item in this group delays closing.
- Articles of Incorporation (corporations) or Articles of Organization (LLCs), proving the entity was properly formed under state law.
- The Operating Agreement (LLCs) or Bylaws (corporations), which spell out signing authority. Underwriters check these to confirm the borrower actually has the power to sign.
- A Certificate of Good Standing from the Secretary of State, confirming the business is current on fees and taxes. An entity not in good standing cannot close.
- IRS CP 575 notice confirming the Employer Identification Number.
- A copy of any local or industry-specific business license.
Beneficial Ownership
Under an interim final rule published in March 2025, domestic companies no longer report beneficial ownership information to FinCEN under the Corporate Transparency Act. The requirement now applies only to entities formed under foreign law that have registered to do business in a U.S. state or tribal jurisdiction.12FinCEN.gov. Beneficial Ownership Information Reporting Your lender’s own compliance policy may still require beneficial ownership disclosure regardless of whether a FinCEN filing is required. Be prepared to identify every individual who directly or indirectly owns 25 percent or more of the entity or who exercises substantial control over it.
Closing Costs to Budget For
Commercial closings carry more fees than most borrowers anticipate, and several are payable before funding.
- Origination fee: typically 0.25 to 0.5 percent of the loan amount at banks and credit unions; 1 to 2 percent or more at private and bridge lenders.
- Appraisal: a few thousand dollars for straightforward properties, more for large or specialized assets.
- Environmental reports: several thousand for a Phase I; $5,000 to $15,000 for a Phase II on a straightforward site.
- Title search and lender’s title insurance: varies by jurisdiction and loan size.
- ALTA/NSPS survey: a few thousand dollars for a simple lot, well over $10,000 for large or complex parcels with numerous Table A items.
- Legal fees: both your attorney and the lender’s attorney charge for review and preparation, and the lender’s legal fees are typically passed through to you.
- Recording fees and transfer taxes: set by local government; some jurisdictions add percentage-based taxes that are material.
- UCC filing fees: usually under $100, varying by state, if the lender takes a security interest in business assets beyond real estate.
Total closing costs often land between 2 and 5 percent of the loan amount, with wide variation by deal size, property type, and local fees.
What the Underwriter Does With Your Package
Once the file is in, a loan officer reviews it for completeness and hands it to a credit analyst. The analyst is not just verifying your numbers. They are actively trying to break them.
Stress testing is central. On variable-rate loans, the analyst raises the interest rate to see how much it can climb before DSCR drops below policy. On multi-tenant properties, vacancy assumptions go up to find the breakeven occupancy. Revenue and expense assumptions get bent to measure how much deterioration the borrower can absorb. For real-estate-secured loans, the analyst may also shift capitalization rates to test collateral value. These results go straight into the credit memo presented to the loan committee. A deal that works today but fails under a modest rate bump or the loss of one tenant typically gets declined or restructured.
With a genuinely complete package, most borrowers see a conditional approval or a request for additional documentation within two to three weeks. Complex deals take longer. The single biggest cause of delay is an incomplete initial submission that forces the analyst to stop and ask for missing items, so the time you spend assembling everything on this checklist before you apply is the time you save at the back end.
