Key takeaways

  • Commercial loans are underwritten mainly on the property's income and the business, not on the owner's personal credit alone.
  • Down payments commonly run, for example, 10% to 35%, depending on program and property type.
  • Two ratios drive the decision: loan-to-value (often 65%-80%) and debt-service coverage (often targeting roughly 1.20-1.35).
  • The term is usually shorter than the amortization schedule, leaving a balloon due at maturity that most borrowers refinance or pay off by selling.
  • Working-capital products may start at a $10,000 minimum; borrowers with FICO 500+ are often considered, and initial approvals can come in about 24-48 hours — never guaranteed.
  • SBA 504 and 7(a) programs fund owner-occupied property; their rules and fees are set by the SBA and change, so verify current terms with an approved lender.
  • MCA relief or reverse consolidation lowers the daily or weekly payment only — it does not pay off, settle, or buy out existing balances.

How Commercial Real Estate Loans Differ From Home Loans

A residential lender asks whether you can pay. A commercial lender asks whether the property can pay, then treats your credit and guarantee as backup. Five structural consequences follow from that shift:

  • The term is shorter than the payoff schedule. Payments are calculated (amortized) over 20–25 years, but the loan matures in 5, 7, or 10. Whatever balance remains on that date — the balloon — is due in full, so owners refinance or sell before it lands.
  • You bring more equity. Where a home buyer might put 3%–20% down, CRE programs commonly want 10%–35%, and thinner deals for riskier property types.
  • You sign personally. Even when an LLC is the named borrower, small-business owners almost always add a personal guarantee, putting personal assets behind the debt.
  • Income is the gate. Underwriters test whether the property's net income clears the payment with a margin — the debt-service coverage ratio explained below — before the loan is approved at all.
  • Recourse is the norm. Most small-business CRE loans are recourse: default lets the lender pursue the guarantor beyond the building. Larger, conservatively leveraged loans are sometimes non-recourse, capping the lender's remedy at the property.

Because every file is hand-underwritten, two owners buying near-identical buildings on the same street can walk away with materially different rates, leverage, and terms based on credit, occupancy, and property type.

Common Types of CRE Financing

There is no single "commercial mortgage." The right structure turns on one question: do you occupy the building, rent it out, or need short-term money while you renovate or stabilize it?

  • Conventional commercial mortgage. A bank or credit-union loan secured by the property. Fits borrowers with solid credit, seasoned cash flow, and a real down payment.
  • SBA 7(a) and 504 loans. Government-guaranteed programs for owner-occupied property, where the business generally must occupy the majority of the space. The 504 pairs a bank loan with a Certified Development Company loan and targets fixed assets like real estate and heavy equipment; the 7(a) is broader in use. Both often allow lower down payments and longer terms than conventional loans, in exchange for eligibility rules, guaranty fees, and heavier paperwork. Program terms and fees are set by the SBA and change periodically — confirm current rules with an SBA-approved lender before you rely on them.
  • Bridge loans. Short-term money to acquire fast, reposition a vacant or under-rented building, or close before permanent financing is ready. Higher rate, short fuse.
  • Construction and renovation loans. Funds released in draws as inspections clear each phase, then paid off or converted to permanent financing once the project stabilizes.
  • Property-secured line of credit / equity access. Revolving or draw-based financing against built-up equity, used for improvements or working capital.
  • CMBS and life-company loans. Large, frequently non-recourse loans on stabilized income property — typically above the size band most small businesses need.

Working-capital products at many marketplace lenders and brokers start at a $10,000 minimum, though a property purchase itself runs far larger. Owners with bruised credit — FICO scores of 500 and up are often considered — may still find options, generally at a higher rate and lower leverage. No lender can promise a yes; terms are never guaranteed and always ride on the underwriting.

The Numbers Lenders Use: LTV, DSCR, and Amortization

Three figures do most of the underwriting work. Learn them and you can predict, before you ever apply, roughly how much you can borrow and what the payment will look like.

  • Loan-to-Value (LTV) is the loan amount divided by the appraised value. A lower LTV means more of your cash in the deal and less risk to the lender. Most CRE loans land in the 65%–80% band, shaded by property type and program.
  • Debt-Service Coverage Ratio (DSCR) is net operating income divided by the annual loan payment. At 1.0, income exactly matches the payment with no room to spare; lenders want a cushion, often 1.20–1.35, so the building earns comfortably more than it owes.
  • Amortization vs. term. Amortization sets the size of each payment; the term sets the day the balance comes due. Stretching amortization shrinks the monthly payment but leaves a larger balloon at maturity.

The ranges below are illustrative — real figures move with the lender, the market, and the property.

MetricWhat it measuresExample target range (illustrative)
Loan-to-Value (LTV)Loan size vs. property valueFor example, 65%–80%
Debt-Service Coverage (DSCR)Income cushion over the paymentFor example, 1.20–1.35
Down paymentOwner equity requiredFor example, 10%–35%
AmortizationSchedule used to size paymentsFor example, 20–25 years
Term / balloonWhen the balance comes dueFor example, 5, 7, or 10 years

A worked DSCR example: a property that nets, for example, $120,000 a year against a $100,000 annual loan payment carries a DSCR of 1.20 — inside a common comfort zone. Drop the net income to $110,000 and the DSCR slips to 1.10, a level some lenders will decline or reprice.

Typical Rates, Terms, and Costs

Price is a function of loan type, your credit and cash flow, the property, and where market rates sit the week you lock. Because published rates go stale in days, the durable skill is reading the components of cost so you can line up two offers and see which is actually cheaper.

  • Rate structure. Rates come fixed for the term or variable — tied to an index such as the prime rate or a published benchmark, plus a margin. A variable loan may open lower and drift higher; a fixed loan trades a bit of starting rate for certainty.
  • Closing costs. Budget for appraisal, an environmental report (required on many property types), title and legal work, and lender origination charges — typically settled at closing.
  • Prepayment terms. Many commercial loans carry a prepayment penalty, a step-down schedule, or yield-maintenance language. If you may sell or refinance early, this clause can cost more than the rate.
  • Reserves and escrows. Lenders may hold reserves for property taxes, insurance, or future capital repairs.

The comparison below is illustrative — it shows how structures rank against each other, not quotes.

Financing typeTypical useRelative cost (illustrative)Typical speed
SBA 504 / 7(a)Owner-occupied purchase or buildLower rate, heaviest paperworkWeeks
Conventional bank mortgagePurchase or refinance, strong borrowersModerateWeeks
Bridge loanFast close, reposition, interim fundingHigher rate, short termDays to a few weeks
Construction loanGround-up or major renovationModerate to higherWeeks

When you compare offers, price the whole deal, not the headline rate: total annualized cost, fees, term length, when the balloon lands, and the prepayment clause. A loan that is half a point cheaper but locks you into a stiff prepayment penalty can cost more the day you sell.

How to Qualify and What Documents to Prepare

Commercial underwriting is document-heavy because the lender is grading two things at once — you and the building. A complete package delivered up front shortens the timeline and strengthens your hand at the negotiating table. Expect to provide:

  • Business financials: profit-and-loss statements, a current balance sheet, and typically two to three years of business tax returns.
  • Personal financials: a personal financial statement and personal tax returns for each owner with a significant stake.
  • Property documents: the purchase contract, current rent roll and leases (for income property), operating statements, and property tax and insurance detail.
  • Entity documents: formation records, the operating agreement or bylaws, and proof of good standing.
  • Third-party reports: the lender orders an appraisal and, for many property types, an environmental assessment.

Underwriters weigh credit history, business cash flow, the equity you bring, DSCR, and property condition together — strength in one can offset a soft spot in another, and stronger credit plus cash flow generally unlocks lower rates and higher leverage. Some lenders issue a preliminary decision fast — initial approvals in roughly 24–48 hours are realistic on simpler requests — but a full CRE closing still takes weeks because appraisal, title, and legal work cannot be rushed. Nothing here is guaranteed; every file is decided on its own merits.

Refinancing and Managing an Existing CRE Loan

Because a commercial loan balloons before it fully amortizes, refinancing is not a rescue move — it is a scheduled event built into the loan. Owners refinance to retire a maturing balloon, capture a lower rate, pull equity out for improvements, or reset the structure. Each time, the lender re-underwrites the property and business against today's value, income, and market rate, so the new terms reflect current conditions rather than the original deal.

Cash-flow strain is a separate problem from refinancing the mortgage, and it calls for a different tool. When a business is choking on short-term, high-cost financing such as a merchant cash advance, a relief or reverse-consolidation arrangement can help by lowering the daily or weekly payment to free up cash. It restructures the payment schedule only — it does not pay off, settle, or buy out the underlying advances. Read any such offer line by line and confirm exactly what it does before you sign.

What to watch while you carry a CRE loan:

  • Mark your balloon date and start the refinance months ahead of maturity, because closings take weeks.
  • Watch DSCR and occupancy — a slide in either can shrink your refinance options and terms.
  • Reread the prepayment clause before refinancing early; the penalty can swallow the rate savings.
  • Keep financials current so you can move the week rates or an opportunity turn in your favor.

Frequently asked questions

How much down payment do I need for commercial real estate?

It depends on the program and the property. Many commercial loans want substantial equity — for example, 10% to 35% of the purchase price. Owner-occupied SBA programs can allow less than conventional loans, while riskier property types or weaker borrowers usually need more. Requirements change over time, so confirm the current figure directly with a lender before you plan around it.

What credit score do I need to qualify?

There is no single cutoff — it varies by lender and loan type. Stronger credit generally earns a lower rate and higher leverage. Some lenders consider borrowers with FICO scores of 500 and above, typically at higher cost and lower loan-to-value. Credit is only one input; business cash flow, your down payment, and the property's income all count too, and no lender can guarantee approval.

What is DSCR and why does it matter?

Debt-service coverage ratio is net operating income divided by annual debt payments — it shows whether the building earns enough to cover the loan with room to spare. At 1.0 income exactly equals the payment; lenders usually want a cushion, often 1.20 to 1.35. For example, $120,000 of net income against a $100,000 annual payment is a DSCR of 1.20. A stronger ratio improves both your odds and your terms.

How fast can I get approved?

A preliminary decision can be quick — for simpler requests, initial approvals in roughly 24 to 48 hours are realistic. A full commercial closing takes longer, because it runs through appraisal, title work, environmental review, and legal documentation. How fast you get there depends heavily on how complete your document package is the day you apply.

What is a balloon payment and how do I handle it?

Many commercial loans amortize over a long schedule — for example, 20 to 25 years — but come due after a shorter term, such as 5, 7, or 10 years. At maturity the remaining balance, the balloon, is owed in full. Most borrowers refinance or sell before that date, so mark your maturity date and start the refinance months ahead, since closings take weeks.

Can I refinance to lower my payments if cash flow is tight?

You can refinance a maturing or high-rate mortgage, and the lender will re-underwrite the property at current value, income, and rates. If the strain comes from short-term, high-cost financing like a merchant cash advance, a relief or reverse-consolidation arrangement can lower the daily or weekly payment to ease cash flow. That restructures the payment only — it does not pay off, settle, or buy out the balances. Read the terms carefully before you agree.
