How Lenders Underwrite a Commercial Real Estate Loan

Every commercial real estate lender asks the same first question: will the property pay for the loan? Underwriting is the process of answering it. This guide walks through what a lender examines, in the order they usually examine it, so you can see your deal the way they will before you send a request.

The Property Comes First

Residential mortgages start with the borrower. Commercial loans start with the asset. The lender wants to know what the property earns today, what it will earn after your plan, and how sure they can be of both.

The figure everything hangs on is net operating income (NOI): rent and other income, minus operating expenses, before debt service and before depreciation or income tax. Lenders build their own NOI rather than accepting yours. They will typically add a vacancy allowance even to a full building, cap management fees at a market rate whether or not you pay one, and set aside a reserve for replacements. If your NOI assumes every unit is leased and nothing ever breaks, expect the lender’s number to be lower.

Three Ratios That Size the Loan

Once the lender has an NOI it trusts, three ratios decide how much it will lend. Whichever produces the smallest loan is the one that binds.

Debt Service Coverage Ratio (DSCR)

NOI divided by annual debt service. A DSCR of 1.25x means the property earns 25 cents of cushion for every dollar of loan payment. Most permanent lenders publish a minimum between 1.20x and 1.35x; bridge lenders may accept less because the plan is to improve the income. Run the numbers on our DSCR calculator before you assume a loan amount.

Loan-to-Value (LTV)

Loan amount divided by appraised value. Published maximums for stabilized property are commonly 65% to 75%. The appraisal, not the purchase price, sets the value, and appraisers use the same conservative NOI the lender does.

Debt Yield

NOI divided by the loan amount. It ignores interest rates and amortization, which is why institutional lenders like it: a 10% debt yield means the same thing whether rates are 5% or 8%. Many set a floor near 10%; some accept less for the strongest property types.

Then the Sponsor

With the property sized, the lender turns to you. The questions are practical: have you owned or operated this kind of property before, do you have liquidity after closing, and does your net worth support a personal guarantee if one is required? A common rule of thumb asks for post-closing liquidity of about 10% of the loan amount and net worth at least equal to it, though every lender sets its own bar. Credit history matters less than in residential lending, but a recent bankruptcy or foreclosure will need an explanation.

Recourse and Guarantees

Recourse means the lender can pursue the guarantor personally if the property is not enough to repay the loan. Non-recourse loans limit the lender to the property, except for “bad acts” such as fraud or unauthorized transfers, which stay personal. Non-recourse is common on stabilized property with institutional lenders; recourse is usual on bridge, construction and smaller balance loans. Lenders on LenderMatrix state which they offer on each program.

What the Lender Will Ask For

• A current rent roll and a trailing twelve-month operating statement, and for a purchase the seller’s statements too.
• Copies of leases for the larger tenants, and the purchase agreement.
• Your personal financial statement, a schedule of the real estate you own, and two or three years of tax returns.
• Entity documents for the borrowing entity.
• For a value-add or construction plan, a budget and timeline with contractor bids.

Third-party reports follow once terms are agreed: an appraisal, an environmental assessment, and often a property condition report. You usually pay for these, and they take two to four weeks.

How to Present a Deal So It Moves

Lenders read hundreds of requests. The ones that move quickly share three habits: the numbers reconcile (the NOI in the summary matches the operating statement), the ask is specific (loan amount, purpose, timing), and the weak points are named up front with the plan to address them. A vacancy problem you explain is a plan; one the lender finds is a red flag.

Where LenderMatrix Fits

Lenders publish their minimum DSCR, maximum LTV, property types and states on their programs. When you describe your deal once, the match shows which of those criteria your deal meets and which it does not, so you send requests to lenders whose box you already fit. It is a comparison, not an approval: every lender underwrites for itself.
