Why Borrowers Face a Refinance Gap

A refinance gap is the shortfall between the loan balance coming due and the amount a replacement lender will fund. It appears when the new loan sizes below the old balance, because the new lender applies its own accepted value, maximum loan-to-value and required debt-service coverage at maturity. Borrowers who started with high debt ratios have the least cushion in those tests, so a modest drop in accepted value or a higher debt cost can leave a cash-in requirement.

How the shortfall appears on the day a loan matures

At maturity the existing loan must be repaid, extended or otherwise restructured. Repayment normally comes from a new loan, and the new lender sizes that loan from current inputs, not from the terms the original lender used.

When the new loan sizes below the outstanding balance, the difference has to come from somewhere. A refinance in that position can require borrower cash-in or a restructuring of the existing debt.

The gap is therefore a comparison of two numbers: what is owed and what the next lender will fund. Neither number says anything about whether the property is performing.

Why loans written at 80% to 85% of value carry the exposure

Loan-to-value is loan principal divided by property value. A borrower that starts near the upper limit of what lenders will fund has already used the room that a later valuation or a tighter lender limit would otherwise absorb.

Borrowers with loans at 80% to 85% can face a gap when a new lender offers 60% of value. The new lender is funding a much smaller slice of the same collateral, and the old balance does not shrink to match.

Apartment development loans kept between 55% and 65% of cost are measured against cost, not value, so they fit a 60% takeout test only if the value the lender accepts is at or above cost. A sponsor in that range has little cash to bring at takeout if value comes in near plan, and more if it comes in below plan.

Debt ratio also decides how much a value decline matters. The same drop in accepted value reduces proceeds by the same dollar amount for every borrower, but it takes a larger share of the cushion where the starting loan was already close to the lender’s limit.

Two sizing tests and why the lower one governs

A replacement loan is sized by more than one test. A collateral test applies a maximum loan-to-value to the value the lender accepts. A cash flow test finds the largest loan whose debt service the net operating income can cover at the lender’s required coverage ratio. The loan is the smaller of the two results.

A rise in the cost of capital works through both tests. Higher rates reduce the loan that a given net operating income can carry, and a wider cost of capital makes it harder for buyers and appraisers to agree on value.

Cost of capital moves of several hundred basis points change debt service sizing immediately and can change the value that lenders and appraisers accept, which moves the loan-to-value result.

Either test can bind. A property with an acceptable appraisal can still be limited by cash flow, and a property with strong coverage can be limited by value. Each test needs its own proceeds figure before the gap is measured.

“It’s just when your cost of capital increases 300, 400, 500 basis points, it makes debt service a little different. And it makes loan to values a little different because no one can agree on value.”

Floating-rate debt and construction takeouts add their own gaps

A floating-rate borrower that wants to extend a maturing loan may have to reset an interest rate hedge at a costly premium. Rising rates also put downward pressure on refinancing proceeds and can require new capital. The hedge reset is a cash cost that sits on top of any principal shortfall.

Construction loans carry a related exposure. The permanent takeout is sized at completion, so a rate increase during construction can leave the takeout below the construction balance and force a cash-in refinance. Rising rates can also trigger a construction loan paydown under a debt service coverage covenant before maturity arrives.

Borrowers have looked to hedge the takeout with forward arrangements to lock in a long-term yield and avoid that outcome.

What closes a gap and what only postpones it

Bringing cash to the closing reduces the balance. Restructuring the debt changes its terms. An extension moves the date and leaves the same principal due, so it postpones a gap without closing it.

Extensions have worked when the underlying property income held up. In a prior downturn, owners could not refinance or sell and repay loans, but tenants did not fail widely and near-zero interest rates let borrowers service debt. Regulators also accommodated bank extension strategies, which gave time real value.

Some advisers favor planning a near-term maturity around current appraisals and market comparables, and not around an assumption that rates will improve soon.

The lender’s position matters too. Limited exit options for borrowers produce a lack of payoffs, which is a major issue for banks holding the loans.

Worked example: a $8 million apartment loan refinanced at maturity

The inputs below are hypothetical and illustrative. A property was acquired at a value of $10,000,000 with an $8,000,000 interest-only loan, which is 80% of value. At maturity the payoff is $8,000,000, fees are zero and the period is the same in every case. Net operating income is $600,000. The new lender caps loan-to-value at 65% and requires 1.25x coverage on interest-only debt service. Those two thresholds are lender specific and are used here only as inputs.

Base case: value holds at $10,000,000 and the new rate is 6%. The value test gives $10,000,000 multiplied by 0.65, which is $6,500,000. The cash flow test starts with the debt service the income can carry: $600,000 divided by 1.25 is $480,000. At 6%, $480,000 divided by 0.06 supports a loan of $8,000,000. The smaller result governs, so proceeds are $6,500,000. The gap is $8,000,000 minus $6,500,000, which is $1,500,000 of cash-in.

Stressed case: accepted value falls to $9,000,000 and the rate is 8%. The value test gives $9,000,000 multiplied by 0.65, which is $5,850,000. The cash flow test gives $480,000 divided by 0.08, which is $6,000,000. The smaller result is $5,850,000. The gap is $8,000,000 minus $5,850,000, which is $2,150,000. That is $650,000 more than in the base case, found by subtracting $1,500,000 from $2,150,000.

A lower-debt comparison on the same property shows how the original debt ratio changes the outcome. If the original loan had been $5,500,000, which is 55% of $10,000,000, the same lender tests would fund $6,500,000 in the base case and $5,850,000 in the stressed case. Proceeds would exceed the balance by $1,000,000 and $350,000 respectively, so no cash-in would be required in either case.

In both cases the value test was the binding one, and the cash flow test came within $150,000 of binding in the stressed case, found by subtracting $5,850,000 from $6,000,000.

Common mistakes in measuring a refinance gap

Carrying the original loan-to-value into the refinance skips the new lender’s own limit. A loan that was 80% of value at origination is sized again at maturity against whatever percentage and whatever value the new lender applies, and in the example above that was 65% of $10,000,000.

Reading the whole gap as a valuation problem hides the cash flow test. Net operating income divided by the required coverage gives the debt service ceiling, and the rate converts that ceiling into a loan. If the rate rises from 6% to 8%, the same income supports a smaller loan even when value is unchanged.

Forgetting to take the lower of the two results overstates proceeds. Averaging the value and cash flow answers, or quoting only the first one calculated, can inflate proceeds by the difference between the two.

Treating an extension as a solution confuses timing with principal. The balance of $8,000,000 is still due after an extension, and a floating-rate borrower may pay a hedge reset cost to get it.

Using a coverage ratio or loan-to-value limit from another deal as a universal rule produces a false gap or a false cushion. Both thresholds are set lender by lender and vary with property type and loan type.

Checklist: questions to ask before a maturity

Confirm the exact payoff amount at maturity. Principal is only part of it, because other amounts due can add to the figure that new proceeds must cover.

Confirm the value the refinancing lender will accept. The loan-to-value result moves with the appraised or underwritten value multiplied by the lender’s loan-to-value limit.

Confirm the maximum loan-to-value that lender applies to this property type. A limit seen on another loan is not a standard.

Confirm the coverage ratio and rate the lender uses in its cash flow test. The same net operating income supports different loans at different rates.

Identify which test produces the lower loan. The smaller of the value and cash flow results sets proceeds.

Check whether an interest rate hedge resets on extension. A reset premium is a cash cost separate from the principal gap.

For a construction loan, calculate how much rate movement the takeout can absorb before it falls below the construction balance. A coverage covenant can also trigger a paydown before maturity.

Check whether the lender would fund the loan if the property income held but value fell. The answer separates the collateral test from the cash flow test.
