Commercial Real Estate Loans (How They Work, What They Cost, and How to Qualify)

Commercial real estate loans finance the purchase, refinancing, or renovation of business property. Here is how the major programs compare, what they cost, and how to pick the right one.

You found the perfect building. It is in the right location, the right size, and the seller is motivated. Your lease is up in four months, and you are tired of writing rent checks that build someone else's equity. Or maybe you want to buy an investment property that cash flows from day one.

The problem is not finding the property. The problem is figuring out which loan program gets you in the door without overpaying or spending months on an application that was never going to get approved.

Commercial real estate loans are not like residential mortgages. The down payments are bigger, the underwriting is more complex, and the wrong loan structure can cost you tens of thousands over the life of the deal. Here is how the major programs work, what they actually cost, and how to pick the one that fits your situation.

How Commercial Real Estate Loans Work

A commercial real estate loan finances the purchase, construction, or renovation of property used for business. The property itself serves as collateral. If you stop making payments, the lender takes the building.

The core mechanics differ from residential lending in three ways. First, lenders evaluate the property's income potential, not just your personal finances. A building that generates $15,000 per month in rent is a stronger deal than one sitting empty, regardless of your personal credit score.

Second, most commercial loans have shorter amortization periods. A 30 year residential mortgage is standard. Commercial loans typically amortize over 15 to 25 years, sometimes with a balloon payment at year 5, 7, or 10 that requires refinancing.

Third, the debt service coverage ratio (DSCR) drives the underwriting. DSCR measures whether the property's net operating income can cover the loan payments. Most lenders want a DSCR of at least 1.25x, meaning the property generates 25% more income than the loan payment requires. If your building produces $10,000 per month in net income, the maximum monthly payment a lender will approve is roughly $8,000.

Owner Occupied vs. Investment Property

The loan program you qualify for depends heavily on whether you will occupy the building. Owner occupied properties, where your business uses at least 51% of the space, unlock SBA loans with 10% down and below market rates. Pure investment properties require conventional financing with 25% to 30% down. This single distinction changes your out of pocket cost by hundreds of thousands of dollars on a typical deal.

Types of Commercial Real Estate Loans

Five loan programs cover the vast majority of small business commercial property deals. Each serves a different situation.

SBA 504 Loans

The SBA 504 is purpose built for owner occupied commercial real estate. The structure splits the deal three ways: a bank provides 50% of the project cost as a first mortgage, a Certified Development Company (CDC) provides 40% as a second mortgage backed by the SBA, and you put down 10%.

The CDC portion carries a fixed rate for 20 or 25 years, typically 1% to 2% below conventional rates. The bank portion can be fixed or variable. This blended structure gives you a lower effective rate than any other program for commercial property.

The catch: processing takes 45 to 90 days, you must occupy at least 51% of the building, and the paperwork is substantial. For a $1 million property, you put down $100,000 instead of the $200,000 to $250,000 a conventional loan requires. That savings alone makes the extra paperwork worth it for most buyers.

SBA 7(a) Loans for Real Estate

The SBA 7(a) program also covers commercial real estate purchases up to $5 million. The main advantage over SBA 504: it is a single loan from a single lender, which simplifies closing. Terms run up to 25 years for real estate.

Rates are variable, tied to prime plus a spread of 1.5% to 2.75%. Down payment is typically 10% to 15%. The 7(a) works well when you need to bundle the real estate purchase with working capital or equipment into a single loan. It is less ideal for pure property acquisition because the variable rate creates long term cost uncertainty.

Conventional Commercial Mortgages

Banks and credit unions offer conventional commercial mortgages without SBA involvement. These move faster, often closing in 30 to 45 days, and have less paperwork. Rates range from 6.5% to 9% depending on creditworthiness and the property.

The tradeoff is a higher down payment: 20% to 25% for owner occupied, 25% to 30% for investment property. Many conventional commercial loans also include balloon payments at 5, 7, or 10 years, meaning you will need to refinance when the balloon comes due. If rates have risen significantly by then, your payment jumps.

CMBS and Conduit Loans

Commercial mortgage backed securities (CMBS) loans are originated by lenders and then packaged and sold to investors. They work best for stabilized properties with strong cash flow and loan amounts above $1 million. Rates are competitive, often 5.5% to 8%, but the terms are rigid. Prepayment penalties are steep, and modifications after closing are nearly impossible because the loan has been securitized.

CMBS loans make sense when you plan to hold the property for the full loan term and do not anticipate needing to refinance or modify the deal. They do not work if your plans might change.

Hard Money and Private Lending

When speed matters more than cost, hard money and private lenders fill the gap. Rates run 10% to 18% with 2 to 5 points in origination fees. Terms are typically 6 to 24 months. These are not long term solutions.

Hard money works for property acquisitions where you need to close fast, renovations before refinancing into permanent debt, or deals where your credit or business history does not qualify for conventional financing yet. Think of it as a bridge loan secured by real estate. The exit strategy is refinancing into a cheaper loan once the property is stabilized or your financials improve.

What Commercial Real Estate Loans Cost

The total cost depends on the loan program, your credit profile, the property type, and the down payment. Here is what each option looks like across the major variables.

Loan TypeInterest RateDown PaymentTerm
SBA 5045.5% to 7.5%10%20 to 25 years
SBA 7(a)Prime + 1.5% to 2.75%10% to 15%Up to 25 years
Conventional bank6.5% to 9%20% to 30%5 to 20 years
CMBS / Conduit5.5% to 8%20% to 25%5 to 10 years
Hard money10% to 18%20% to 40%6 to 24 months

Here is a real cost comparison. You want to buy a $1.2 million office building that your business will occupy. With an SBA 504 loan, you put down $120,000 and pay roughly 6.5% blended across the two loan components. Monthly payment: approximately $7,200 on a 25 year term. Total interest over 25 years: roughly $960,000.

With a conventional bank mortgage at 8% and 25% down ($300,000), monthly payment is approximately $6,900 on a 20 year term. Total interest: roughly $760,000. You pay less total interest, but you need $180,000 more upfront. For most small businesses, the lower down payment of SBA 504 outweighs the higher interest cost because that $180,000 stays in the business generating revenue.

How to Qualify for a Commercial Real Estate Loan

Commercial real estate underwriting evaluates three things: the borrower, the property, and the deal structure. Weakness in one area can be offset by strength in the other two, but all three need to pass minimum thresholds.

Borrower Requirements

Credit score. SBA loans need 660 to 680 minimum. Conventional bank loans want 700 or higher. Below 650, you are looking at hard money or private lending. Your personal credit score matters even on a business loan because most commercial lenders require a personal guarantee.

Business revenue and history. Most lenders require two years of business tax returns showing stable or growing revenue. Startups can qualify for SBA loans with a strong business plan and industry experience, but expect more scrutiny. If your business is pre-revenue, commercial real estate lending is extremely difficult to access.

Liquidity. Lenders want to see that you have cash reserves beyond the down payment. Six months of loan payments in liquid reserves is a common requirement. This proves you can survive a rough stretch without defaulting.

Property Requirements

Appraisal. Every commercial real estate loan requires a third party appraisal. The lender will not lend more than a certain percentage of the appraised value (the loan to value ratio). If you are paying $1 million but the appraisal comes back at $900,000, the lender bases their loan on $900,000. You cover the gap.

Environmental assessment. Phase I environmental site assessments are required for most commercial property loans. This checks for soil contamination, hazardous materials, and environmental liabilities. If the Phase I turns up concerns, a Phase II with actual soil testing may be required. Budget $2,000 to $5,000 for the Phase I and $10,000 or more if Phase II is needed.

Property condition. Lenders evaluate the physical condition of the building. Significant deferred maintenance, structural issues, or code violations can kill a deal or require escrow holdbacks for repairs. Getting a property inspection before you go under contract helps you avoid surprises during underwriting.

Deal Structure Requirements

Debt service coverage ratio. The DSCR is the single most important number in commercial real estate lending. Net operating income divided by annual debt payments must equal at least 1.25x for most lenders. SBA programs sometimes accept 1.15x. CMBS loans typically want 1.30x or higher.

Loan to value ratio. Most programs cap at 75% to 90% LTV. SBA 504 goes to 90% for owner occupied. Conventional caps at 75% to 80%. Investment property conventional loans cap at 70% to 75%. The lower the LTV, the better your rate and terms.

The Application Process Step by Step

Commercial real estate loans involve more documentation and more steps than a term loan or line of credit. Here is the sequence, so nothing catches you off guard.

  1. 1

    Get Pre-Qualified

    Before you shop for property, talk to lenders. Provide your business financials, personal credit report, and a general description of what you want to buy. A pre-qualification letter tells sellers you are a serious buyer and tells you what price range and loan terms to expect.

  2. 2

    Go Under Contract

    Once you find the property, negotiate purchase terms and execute a purchase and sale agreement. Include a financing contingency that gives you 60 to 90 days to secure the loan. This protects your earnest money if the financing does not come through.

  3. 3

    Submit Full Application

    Provide two to three years of business and personal tax returns, current profit and loss statement, balance sheet, bank statements, a schedule of existing debts, and the purchase agreement. SBA loans require additional forms including SBA Form 1919 and personal financial statements.

  4. 4

    Third Party Reports

    The lender orders an appraisal, Phase I environmental assessment, and sometimes a property condition report. These take 2 to 4 weeks and cost $5,000 to $15,000 combined. You typically pay for these upfront, and the money is not refundable if the deal falls apart.

  5. 5

    Underwriting and Approval

    The lender reviews everything: your financials, the property reports, the deal structure. Expect follow up questions. Respond within 24 hours to keep the process moving. Bank approvals typically take 1 to 3 weeks after all documents are in. SBA adds another 1 to 2 weeks for their authorization.

  6. 6

    Closing

    Once approved, the lender issues a commitment letter outlining all terms and conditions. Title work, insurance, and legal review happen in parallel. Closing costs run 2% to 5% of the loan amount on top of your down payment. Bring a cashier's check, sign the stack of documents, and the property is yours.

Mistakes That Kill Commercial Real Estate Deals

Commercial property deals fall apart for preventable reasons. Here are the ones that cost business owners the most time and money.

Skipping the pre-qualification. You find the perfect building, spend weeks negotiating, pay $3,000 for inspections, and then discover your financials do not support the loan amount. Pre-qualification takes a few days and costs nothing. It saves you from chasing properties you cannot finance.

Ignoring the balloon payment. A 20 year amortization with a 7 year balloon means you owe the full remaining balance in year 7. If commercial rates have risen 3% by then, your refinance payment could jump 30% or more. Run the numbers for your balloon date under multiple rate scenarios before you sign. If the worst case scenario would strain your cash flow, look for a fully amortizing loan even if the rate is slightly higher now.

Underestimating closing costs. Between the down payment, appraisal, environmental assessment, title insurance, legal fees, origination points, and pre-paid insurance and taxes, total out of pocket costs run 25% to 35% of the purchase price on a conventional deal. SBA 504 brings that down to 13% to 17%. Budget for the real number, not just the down payment.

Not negotiating the purchase price after the appraisal. If the appraisal comes in below your contract price, you have leverage. The lender will only finance based on the appraised value, which means you need to cover the difference in cash. Go back to the seller and renegotiate. Most sellers would rather lower the price than lose the deal and start over with a new buyer.

Choosing the wrong loan program. An owner occupied business paying 8% on a conventional mortgage when they could have gotten 6% through SBA 504 is throwing away money every month for the life of the loan. On a $1 million loan, that is roughly $130,000 in excess interest over 20 years. Talk to lenders who offer multiple programs, not just one.

Industries That Buy Commercial Property Most

Any business with a physical location can benefit from owning instead of leasing. But some industries find the economics especially compelling.

Medical practices and dental offices invest heavily in tenant improvements like exam rooms, specialized plumbing, and diagnostic equipment wiring. When your buildout costs $200,000 or more, owning the building means you never lose that investment to a lease expiration. Medical and dental practices also tend to stay in one location for decades, which makes the long term math of ownership strongly favorable.

Auto repair shops and collision centers need specialized facilities with service bays, lifts, ventilation, and environmental permits. These modifications are expensive and specific to the property. Owning protects the investment and eliminates the risk of a landlord not renewing the lease after you have spent six figures on improvements.

Restaurant owners who find a high traffic location with the right kitchen layout often benefit from ownership. A restaurant lease in a prime location can be $8,000 to $15,000 per month. A mortgage payment on the same property might be comparable, and after 20 years, you own the building outright. The challenge is that restaurant margins are thin, so the down payment can be harder to accumulate.

Contractors and construction companies need warehouse and yard space for equipment, materials, and vehicles. Logistics companies need distribution space. Buying a facility with yard and warehouse space locks in your costs and gives you an asset that appreciates while your business uses it.

The Bottom Line on Commercial Real Estate Loans

Buying commercial property is one of the biggest financial decisions a business owner makes. The right loan program can save you hundreds of thousands in interest and down payment costs over the life of the deal. The wrong one drains cash that your business needs for operations and growth.

If you are buying a building your business will occupy, start with SBA 504. The 10% down payment and below market fixed rates are hard to beat. If you need to close fast, a bridge loan can hold the deal together while SBA processing runs its course. If you are buying investment property, conventional commercial mortgages are your primary option, and the DSCR will drive what you qualify for.

Whatever route you take, get pre-qualified before you shop, budget for the real total cost including closing and reserves, and do not sign anything with a balloon payment you have not stress tested against rate increases. Check your eligibility to see which commercial real estate loan programs fit your business profile.

Frequently Asked Questions

What is a commercial real estate loan?

A commercial real estate loan finances the purchase, refinancing, or renovation of property used for business purposes. This includes office buildings, retail spaces, warehouses, and mixed use properties. Loan amounts typically range from $250,000 to $5 million for small businesses, with terms between 5 and 25 years depending on the lender and program. The property serves as collateral, and lenders evaluate both the borrower's creditworthiness and the property's income potential.

How much do you need for a down payment on a commercial property?

Down payments range from 10% to 30% depending on the loan program. SBA 504 loans require just 10% for owner occupied properties. SBA 7(a) loans typically need 10% to 15%. Conventional bank loans require 20% to 25% for owner occupied and 25% to 30% for investment property. On a $1 million property, that is the difference between $100,000 and $300,000 out of pocket.

What credit score do you need for a commercial real estate loan?

SBA loans require 660 to 680 minimum in practice. Conventional bank commercial mortgages prefer 700 or higher. Credit unions and CDFI lenders may work with scores as low as 620. Below that, hard money lenders are your primary option at significantly higher rates. While credit score matters, lenders also weigh the property's cash flow, your business financials, and the debt service coverage ratio heavily.

How long does it take to close a commercial real estate loan?

Conventional bank loans close in 30 to 60 days. SBA 504 loans take 45 to 90 days because of the dual approval process. SBA 7(a) loans close in 30 to 75 days. Hard money lenders can fund in 7 to 21 days. The biggest delays come from appraisals, environmental assessments, and title work. Having your documentation organized before you apply is the single best way to speed up the process.

Can you get a commercial real estate loan for investment property?

Yes, but the terms are less favorable. SBA programs require at least 51% owner occupancy, so they are not available for pure investment deals. Conventional commercial mortgages for investment property require 25% to 30% down with rates 0.5% to 1% higher than owner occupied loans. Lenders also require higher DSCR, usually 1.30x or above, because the risk is higher when the borrower does not occupy the property.
