The Cash Flow Waterfall That Changes Mid-Deal: How Leasing Costs, TI/LC Caps, and 'Extraordinary Expense' Definitions Shift DSCR and Release Economics in Transitional Loans

Transitional loans are sold on a simple premise: borrower stabilizes the asset, cash flow improves, DSCR climbs, and at a specified threshold, principal release or refinance occurs. The math is clean. The waterfall is logical. And then, somewhere between closing and year two, the definitions that govern what flows into DSCR suddenly narrow, what flows out suddenly expands, and the borrower discovers that the cash flow waterfall was never static. It was always a moving target, because the lender's underwriting reserved the right to redefine ordinary expense, leasing cost allocation, and tenant improvement caps mid-deal.

This is not a flaw in transitional lending. It is the structural consequence of how lenders protect themselves when the future is genuinely uncertain. But it is also the reason why many transitional deals that looked stable on pro forma never reach their release targets on schedule, and why borrowers and sponsors need to understand not just what the waterfall is, but what assumptions inside it are hardwired and which ones are subject to post-closing reinterpretation.

When a lender underwrites a transitional deal, the NOI model includes assumptions about operating expense ratios, maintenance costs, administrative overhead, and marketing spend. These assumptions are often based on stabilized comps or the borrower's historical experience. But the underwriting document rarely locks down what constitutes an "ordinary" operating expense versus what is capitalized, amortized, or deferred.

This ambiguity matters enormously because the loan documents typically include language allowing the lender to "adjust" or "recast" NOI for purposes of testing DSCR, debt yield, or release thresholds. That language often permits the lender to exclude items deemed "non-recurring" or "extraordinary," but the definition of extraordinary is left to the lender's sole discretion, exercised by the servicer or special servicer after closing.

A common scenario: the underwriter modeled a $50,000 annual marketing budget for lease-up. But in year two, when the asset is 75% occupied and the borrower wants to push for 85% to trigger a release test, the special servicer informs the borrower that the additional $30,000 marketing spend to close that gap is deemed "extraordinary" and will be excluded from the DSCR calculation for release purposes. The effect is perverse: the borrower's effort to stabilize the asset actually reduces the DSCR available for release, because the expense required to achieve stabilization is removed from the denominator.

The structural issue is that the lender has already been paid interest and principal on the assumption that the asset would reach a certain stabilized NOI. Once the lender is in the deal, the incentive is to tighten the definition of ordinary expense to protect the release threshold or extend the loan life. The borrower, meanwhile, discovers that the cash flow it expected to capture for release is partially claimed by the lender's reclassification of expense.

Transitional loans almost always include caps on tenant improvement allowances (TI) and leasing commissions (LC). These caps are stated as a dollar amount (e.g., "$500,000 aggregate for TI and LC") or as a percentage of rent (e.g., "8% of first-year rent for LC, capped at $300,000"). The stated purpose is to control the borrower's incentive to offer excessive concessions or to build in padding for unexpected lease-up costs.

But the waterfall between underwriting and execution often shifts in three ways. First, the lender's advance of TI and LC funds is discretionary. The loan documents typically allow the lender to approve or deny TI/LC requests on a lease-by-lease basis, and to reserve the right to fund only a portion of the requested amount. This means the borrower cannot assume that every dollar of the cap will be available when needed. If leasing momentum slows or if the lender becomes more conservative about credit quality, the lender may approve only 50% of requested TI for a given lease, forcing the borrower to either reduce tenant allowances (and lose the lease) or fund the gap from working capital.

Second, the treatment of TI and LC in the DSCR calculation is often asymmetrical. When calculating underwritten DSCR, the lender assumes that TI and LC are paid from the lender's advance (a source of funds), not from NOI. But once the deal closes, the servicer may begin to treat portions of TI and LC as operating expenses, or may reclassify leasing commissions paid to third parties as a deduction from rent revenue. The effect is that the NOI used for release testing declines relative to the underwritten model, because costs that were assumed to be funded by the lender are now treated as expense.

Third, the cap itself may be redefined. A cap of "$500,000 aggregate" sounds fixed, but the documents often include carve-outs: new leases above a certain size may have higher allowances, renewal leases may be subject to different caps, and replacement of a major tenant may trigger a higher cap due to market conditions. The lender reserves the right to approve exceptions. In practice, the $500,000 cap becomes a soft cap, and the borrower finds that by year three, the aggregate spend has climbed to $700,000, with the lender's consent, but now the borrower is liable for the overage.

Most transitional loan documents include a carve-out from the DSCR calculation for "extraordinary" or "non-recurring" expenses. These are typically defined as one-time costs such as major capital repairs, litigation expenses, environmental remediation, or emergency maintenance. The purpose is sound: the lender does not want a single large expense to cause a false DSCR failure.

But the definition of extraordinary is often vague, and the lender's discretion to determine what qualifies is broad. Consider a scenario: the asset has an aging roof that the borrower knew would need replacement during the loan term. The underwriter modeled a $200,000 roof replacement in year three, and included it in the stabilized operating expense. But when the roof actually needs replacement in year two, the servicer argues that because the expense was "not anticipated at closing," it is extraordinary and should be excluded from the DSCR calculation for release purposes.

The effect is that the same expense can be treated in two different ways, depending on the timing and the lender's preference. If the lender wants to release principal, the expense is excluded as extraordinary, and the DSCR appears strong. If the lender wants to extend the loan or tighten the release terms, the expense is included as ordinary, and the DSCR declines.

This flexibility is not accidental. It is structural. The lender knows that transitional assets are inherently uncertain, and the lender wants to preserve the ability to adjust the underwriting post-closing based on what actually happens. But this creates a perverse incentive: the borrower is penalized if the asset stabilizes faster than expected (because the lender tightens the definition of ordinary expense to slow release), and rewarded if the asset stabilizes slower than expected (because the lender loosens the definition to preserve the borrower's incentive to continue investing).

Transitional loans typically include a release test: once DSCR reaches a specified level (e.g., 1.25x), a percentage of principal becomes releasable. But the DSCR used for the release test is often not the same as the underwritten DSCR, because the lender has the right to recast or adjust NOI based on actual operations, servicer analysis, or changed underwriting assumptions.

A common practice is for the lender to publish a "servicer's DSCR" or "adjusted DSCR" that differs from the borrower's calculation. The servicer may exclude certain revenue (e.g., parking income, if deemed non-core), add back reserves for bad debt or concessions, or reclassify operating expenses based on revised underwriting. The result is that the DSCR available for release is often lower than the borrower's internal calculation, and the release test is delayed by one to three years.

The structural reason is that the lender is not just protecting against downside risk; the lender is also protecting against the borrower's incentive to manipulate NOI upward to trigger release. By reserving the right to recast DSCR post-closing, the lender maintains control over the release timeline, and can adjust the hurdle based on market conditions, credit performance, or changes in the lender's risk appetite.

For borrowers, this means that the release schedule promised in the term sheet is more of a guideline than a commitment. The actual release depends on the servicer's post-closing underwriting, which may be more conservative than the original lender's analysis.

Sophisticated borrowers and sponsors can protect themselves by negotiating specific carve-outs and definitions in the loan documents before closing. The key moves are: (1) define "ordinary expense" with specificity, including dollar thresholds or historical baselines that lock the lender's calculation; (2) establish a fixed TI/LC cap with minimal exceptions, and require lender approval of exceptions in writing before the work is performed; (3) create a schedule of anticipated capital improvements and define them as extraordinary only if they fall outside the schedule and exceed a dollar threshold; and (4) establish a methodology for calculating servicer DSCR that mirrors the underwritten DSCR, with any adjustments disclosed in advance and subject to borrower review.

The reality is that lenders will always want to preserve flexibility, and borrowers will always want certainty. The negotiation is about where that line is drawn. Borrowers with strong equity or market position can push the line toward certainty; borrowers with weak equity or in a soft market will cede flexibility to the lender.

What I'm watching next:

• How transitional lenders are adjusting their servicer guidelines post-2024 rate cycle, and whether the definition of extraordinary expense is tightening as a way to slow release and extend loan life in a declining rate environment.
• Whether borrowers are beginning to demand holdback reserves or escrow accounts for anticipated extraordinary expenses, as a way to lock in the treatment of major capital items before closing.
• How the rise of balance sheet lenders and direct lending is changing the negotiation dynamic around DSCR recast rights, particularly whether direct lenders are more willing to lock down definitions in exchange for higher rates.
