Conventional Commercial Loans: Speed, Flexibility, and Portfolio Lending

Not every commercial real estate deal needs an SBA loan. For business owners with strong financials, healthy cash reserves, and a desire for speed and simplicity, conventional commercial loans are often the better path. These are the traditional bank loans that have financed commercial real estate for decades: no government guarantee, no SBA forms, no occupancy requirements, and a closing timeline measured in weeks, not months.

This guide explains how conventional commercial loans work, when they are the right choice, and what to expect from rates, terms, and the application process.

What Is a Conventional Commercial Loan?

A conventional commercial loan is financing provided by a bank, credit union, or private lender without any government guarantee or backing. The lender takes on 100% of the credit risk. Because there is no government safety net, conventional lenders set their own eligibility criteria, rate structures, and terms. This makes every conventional loan somewhat unique, shaped by the individual lender's risk appetite, portfolio strategy, and relationship with the borrower.

The absence of a government guarantee is both the greatest disadvantage and the greatest advantage of conventional lending. Without a guarantee, lenders require more from the borrower (higher down payments, stronger credit, more proven cash flow). But without government involvement, the process is faster, simpler, and more flexible.

Key Terms at a Glance

The Balloon Payment Structure

The most important structural difference between conventional and SBA loans is the balloon payment. Here is how it works:

When you take out a conventional commercial mortgage, the loan has two timelines: the amortization period and the term. The amortization period (typically 20 to 25 years) determines your monthly payment calculation. The term (typically 5 to 10 years) determines when the remaining balance comes due.

For example, a 1 million loan with a 25-year amortization and a 7-year term would have monthly payments calculated as if you were paying it off over 25 years. But after 7 years, the remaining balance (roughly 820,000) comes due as a lump sum. At that point, you refinance into a new loan, pay off the balance from other sources, or negotiate a renewal with your lender.

The Refinancing Risk

The balloon payment creates what is called refinancing risk. When the term expires, you are essentially forced to apply for a new loan. If interest rates have risen significantly, your new payment could be much higher. If your business has experienced a downturn, you may struggle to qualify for refinancing on favorable terms. In extreme cases (like the 2008 financial crisis), some borrowers were unable to refinance at all.

This is the primary risk of conventional commercial lending and the main reason SBA loans, with their fully amortizing 25-year terms, are so popular. With an SBA loan, you never face a balloon payment. With a conventional loan, you face one every 5 to 10 years.

Loan-to-Value (LTV) Ratios

The LTV ratio determines how much the bank will lend relative to the property's appraised value. Conventional commercial lenders typically cap LTV at 65% to 80%, meaning you need 20% to 35% down.

The higher down payment is the biggest practical tradeoff when choosing conventional over SBA. On a 2 million property, the difference between 10% down (SBA) and 25% down (conventional) is 300,000 in additional cash required at closing.

Balance Sheet Lending vs. Securitized Lending

Understanding how your lender funds its loans helps you understand why terms are structured the way they are.

Balance Sheet (Portfolio) Lenders

Community banks and credit unions typically keep commercial real estate loans on their own balance sheet. This is called portfolio lending. The bank uses its depositors' funds to make the loan and keeps the loan for its entire term.

Portfolio lending gives the bank enormous flexibility. The loan does not need to meet rigid secondary-market guidelines, so the bank can structure terms to fit the specific deal. If you have a unique property, an unconventional income stream, or a deal structure that does not fit into a standard box, a portfolio lender is more likely to find a way to make it work.

The trade-off is that the bank carries the risk. If you default, the bank absorbs the loss directly. This is why portfolio lenders require higher down payments, balloon structures (to re-evaluate risk periodically), and stronger borrower profiles.

Securitized (CMBS) Lenders

Larger commercial loans may be originated by a bank but sold into a commercial mortgage-backed securities (CMBS) pool. These loans are packaged together and sold to investors. CMBS loans tend to have more rigid underwriting criteria, standardized terms, and less flexibility for exceptions. They are more common for larger deals (typically 2 million and above) and are serviced by a third-party servicer rather than the originating bank.

For owner-occupied commercial real estate under 5 million, you will almost always be working with a portfolio lender rather than a CMBS lender.

Relationship Banking: The Conventional Advantage

One of the most underappreciated benefits of conventional lending is the relationship banking dynamic. When you borrow conventionally from a community bank or credit union, you are building a direct relationship with an institution that has the discretion to make decisions based on your overall picture, not just a formula.

Here is what relationship banking can get you:

• More favorable terms over time: As you build history with a lender, future loans often come with better rates and lower fees
• Faster decisions: A banker who knows your business can underwrite and approve deals faster than one starting from scratch
• Flexibility on exceptions: Portfolio lenders can make exceptions to their standard policies for strong relationships
• Easier renewals: When your balloon comes due, a lender who knows you well is more likely to offer favorable renewal terms
• Access to other services: Lines of credit, equipment financing, and operating accounts are all easier when you have an established banking relationship

When Conventional Beats SBA

There are several scenarios where conventional financing is clearly the better choice:

You Have Strong Financials

If you have excellent credit (720+), substantial liquidity, a well-established business with strong cash flow, and the ability to put 20% to 25% down without straining your reserves, the SBA guarantee is not doing much for you. You would qualify for a good conventional loan on your own merits, and the SBA guarantee fee (up to 3.75% of the guaranteed portion) is money you do not need to spend.

Speed Is Critical

If you are competing for a property in a competitive market, or the seller has imposed a tight closing deadline, a 30 to 45 day conventional closing can be the difference between winning and losing the deal. SBA timelines of 45 to 90 days may not work.

You Need Flexibility

Conventional loans have no occupancy requirements, no SBA use-of-proceeds restrictions, and no government-mandated forms. If your deal does not fit neatly into SBA guidelines, conventional lending gives you and the lender the freedom to structure it however it needs to be structured.

The Property Is Not Owner-Occupied

If you are purchasing investment property or a building where you will occupy less than 51% of the space, SBA is not an option. Conventional financing is the default for non-owner-occupied commercial real estate.

You Want to Avoid Variable Rate Risk Without the 504 Complexity

Conventional lenders offer fixed-rate options for their term period (5 to 10 years). While this is shorter than the 504's 20 to 25 year fixed rate, it may be sufficient for borrowers who plan to sell or refinance within that period. And the closing is dramatically simpler than a 504.

The Higher Down Payment Tradeoff

The biggest disadvantage of conventional lending for most borrowers is the down payment. Let us look at a concrete comparison:

The additional 250,000 to 300,000 in cash required for a conventional loan is significant for many business owners. But for those with the capital, the savings on the guarantee fee, faster closing, and simpler process can make conventional the smarter financial decision.

Faster Closing Timelines

Conventional commercial loans typically close in 30 to 45 days. Here is why they are faster:

• No SBA authorization required: The lender makes the approval decision internally, without submitting anything to a government agency.
• Fewer required documents: No SBA forms, no eligibility certifications, no size standard verifications.
• Simpler underwriting: While thorough, conventional underwriting focuses on the fundamentals (cash flow, collateral, credit) without the overlay of SBA program compliance.
• In-house decision making: Portfolio lenders have the authority to approve and close the loan entirely within their own institution.

No SBA Restrictions or Guarantee Fees

When you go conventional, you avoid all of the following:

• SBA guarantee fee (up to 3.75% of the guaranteed portion)
• 51% occupancy requirement
• SBA size standards and eligibility rules
• Restrictions on business types
• SBA-specific forms and documentation
• SBA standby agreements for equity injection sources
• SBA review timelines

For business owners who qualify on their own merits, these restrictions are unnecessary friction. The guarantee fee alone, on a 1.5 million loan, can exceed 40,000. That is real money that stays in your pocket with a conventional loan.

Conventional Loan Process: What to Expect

Step 1: Initial Conversation (Day 1-3)

You meet with a commercial lender to discuss the project, your financial situation, and the property. The banker provides preliminary terms and a checklist of required documents.

Step 2: Application and Documentation (Days 3-10)

You submit your financial package, including tax returns, financial statements, a personal financial statement, the purchase contract, and any other items the lender requests. The lender orders the appraisal and title work.

Step 3: Underwriting (Days 10-25)

The lender's credit team reviews your financials, analyzes cash flow, evaluates collateral, and prepares a credit memo for approval. The lender's loan committee reviews and approves the deal.

Step 4: Commitment (Days 25-30)

You receive a commitment letter outlining final terms and any remaining conditions. You review, negotiate if needed, and accept.

Step 5: Closing (Days 30-45)

Legal documents are prepared, final conditions are cleared, and the transaction closes through a title company. Funds are disbursed.
