Why Different Lenders Size the Same Property Differently

Lenders quote different loan amounts on one property because each applies its own borrowing limit, coverage threshold and pricing, and those inputs trace back to how the lender raises and constrains its own capital. The offer equals the smallest result from several tests run on expected net operating income and value. Two lenders can therefore be held back by different tests on identical cash flow.

The offer is the smallest result from several separate tests

A lender runs a proposed loan through more than one test and the lowest answer becomes the offer. The usual tests are a coverage test on income, a borrowing limit against value and a payment test at the lender’s pricing.

Income comes first. Net operating income is the rent a property is expected to bring in after operating expenses, and lenders size on that expected figure so the borrower can repay and still keep cash flow for unplanned costs.

The coverage test then caps the payment. Debt service coverage ratio is net operating income divided by annual debt service, and lenders use it as a risk measure. A required ratio therefore sets a ceiling on annual debt service equal to net operating income divided by that ratio.

Each lender’s ratio, borrowing limit and pricing depend on its capital sources and related constraints. The same property can size differently across lenders for that reason alone, before any disagreement about the property itself.

“The ratio of the net operating income divided by the annual debt service requirement. Lenders use this ratio as a risk measure.”

How two underwriters reach different income from one rent roll

Loan size can diverge before any ratio is applied, because the lenders may not start from the same net operating income. Rent and expense assumptions both flow straight into the debt capacity calculation.

The effect compounds. When income falls and expenses rise, net operating income falls on both sides at once, and a lender that underwrites the lower expected figure supports a smaller payment at any given coverage requirement.

Properties with thin margins show the problem most clearly. Lower rents can produce low or negative net operating income, and a negative figure leaves no room for debt service at all.

Two quotes for the same asset can therefore differ because of income, required coverage or both. The loan amounts alone do not say which input moved.

Turning a payment ceiling into loan principal

The coverage test produces a payment ceiling, and pricing converts that ceiling into principal. The conversion divides the maximum annual debt service by the loan constant, which is the annual payment per dollar borrowed under the lender’s rate and repayment schedule.

A higher constant means each borrowed dollar costs more to carry, so the same payment ceiling supports less principal. A lender with costlier funds or a shorter amortization schedule can offer less on identical income even with the same required coverage.

Capital sources sit behind these inputs. The borrowing limits, coverage thresholds and pricing a lender applies depend on where its money comes from and what constraints attach to it, which is why a threshold at one lender carries no information about another.

Why a second layer of debt still answers to the first lender

Seller financing placed behind a first mortgage does not escape the first lender’s coverage requirement. The first lender’s debt service coverage test still applies, which limits how far a seller can structure around a financing gap.

The same mechanic applies to any junior piece. Its payments count toward total debt service under the senior test, so extra layers consume coverage that the first loan sized against.

Financing also affects timing. In one quarter’s remarks from a small-cap REIT operator, buyers were asking for 45 to 60 days of diligence and sometimes 30 to 45 days to close, with debt financing cited as the reason.

Worked example: one hypothetical property sized by two lenders

The inputs are hypothetical and identical for both lenders: year-one net operating income of $1,200,000 and a value of $16,000,000. Fees and the borrower’s capital are held the same, and each lender sizes to the smaller of its coverage result and its value limit.

Base case, lender A: required coverage is 1.25x, the loan constant is 7.5 percent and the value limit is 70 percent. Maximum annual debt service is $1,200,000 divided by 1.25, which is $960,000. The coverage-based loan is $960,000 divided by 0.075, which is $12,800,000. The value-based loan is $16,000,000 multiplied by 0.70, which is $11,200,000. The value limit is smaller, so lender A offers $11,200,000.

At that loan, annual debt service is $11,200,000 multiplied by 0.075, which is $840,000, and actual coverage is $1,200,000 divided by $840,000, or 1.43x. That is above the 1.25x requirement, so some coverage capacity goes unused.

Alternative case, lender B: required coverage is 1.50x, the loan constant is 8 percent and the value limit is 75 percent. Maximum annual debt service is $1,200,000 divided by 1.50, which is $800,000. The coverage-based loan is $800,000 divided by 0.08, which is $10,000,000. The value-based loan is $16,000,000 multiplied by 0.75, which is $12,000,000. Coverage is now the smaller result, so lender B offers $10,000,000, equal to 62.5 percent of value.

On the same property, lender A offers $1,200,000 more than lender B, a gap of 10.71 percent of lender A’s loan. Lender A is held back by its value limit and lender B by its coverage requirement and pricing. Lender B’s higher value limit never comes into play.

Mistakes that distort a comparison of lender quotes

Reading the gap as a pricing difference alone misreads which test binds. In the example, a lower loan constant at lender B would raise its offer only until it reached its own value result, and the same change would add nothing at lender A because A is already held back by value.

Judging a lender by its required coverage hides slack that actual coverage reveals. Lender A requires 1.25x yet its quoted loan carries 1.43x, so the stated threshold says little about how much payment capacity the offer actually uses.

Carrying one coverage figure across lenders treats a lender-specific input as a universal one. Thresholds, borrowing limits and pricing vary with each lender’s capital sources, so a figure that fits one quote can be wrong for the next.

Dividing a payment ceiling by the wrong constant overstates principal. A constant that ignores amortization is smaller than one that includes it, and the smaller divisor produces the larger quotient for the same ceiling.

Sizing from an old or optimistic income figure also distorts the result. Lenders size on expected net operating income, and if expenses rose or rents fell since the figure was struck, the supportable payment falls with it.

Questions that identify the binding constraint in each quote

Which net operating income did each lender underwrite? Rent after operating expenses is the base of every other test, so a different starting figure changes everything below it.

What coverage ratio does each lender require? The ratio caps annual debt service at net operating income divided by that requirement.

What loan constant applies to each quote? The constant converts the payment ceiling into principal, and a higher one reduces proceeds on the same ceiling.

Does a value or borrowing limit bind before the coverage test does? The smaller of the two results governs, and the unused one is invisible in the quoted amount.

How much coverage does the quoted loan actually carry? Actual coverage above the requirement signals that another test is binding.

Which capital source or related constraint sits behind the lender’s limits? Those constraints shape the borrowing limits, coverage thresholds and pricing the lender applies.

Does any junior or seller financing add payments under the first lender’s test? Those payments count toward total debt service and use up coverage.
