Lesson 9 of 15

The Maturity Wall & Exit Risk

A loan can make every payment on time for years and still fail — on one specific day, at maturity, when it cannot refinance. This is the second of the two ways a commercial mortgage dies, and it is the one that catches people who only watch coverage.

Return to the spine of the course: a commercial mortgage fails two ways. It can’t cover the debt — the credit axis, DSCR, everything in the last few lessons. Or it can’t exit at maturity — the duration axis, which is this lesson. These are genuinely independent failure modes, and that independence is the trap. A loan can be perfectly healthy on the first axis and doomed on the second. It covers its current payment comfortably, month after month, right up until the balloon comes due and there is no new loan available to pay it off. Coverage was never the problem. Exit was.

Why would a covering loan fail to refinance? Because refinancing is not underwritten against the old loan’s rate — it is underwritten against today’s rate, at today’s value, under today’s lending appetite. A loan made at 3.5% that covers fine at 3.5% must be replaced by a loan at, say, 7%, and at 7% the same NOI supports far less debt. The building didn’t change. The exit changed underneath it. This is why the maturity wall is not really a calendar — a pile of loans coming due — it is an exit-gap wall: the distance between what the loan owes and what the property can actually refinance into under current conditions.

The platform makes this precise with a single, teachable adjustment. Take the loan’s coverage and stress it for the takeout: a rough refinance DSCR is the current DSCR scaled by the ratio of the in-place rate to the likely takeout rate — refi_dscr ≈ dscr × (in-place rate / takeout rate). When rates have risen, that ratio is well below one, and it can push a comfortable 1.5x current coverage down to a sub-1.0x refinance coverage. That gap between the two numbers is the exit risk, quantified. The most dangerous loans this reveals are the cliff loans: the ones that cover now and fail refi — invisible to anyone watching only current DSCR, glaringly exposed the moment you apply the takeout stress. A loan that looks fine and refinances into a wall is precisely the kind of thing a coverage-only reader never sees coming.

This also tells you where to point the tool, and it ties back to fixed-versus-floating. Exit risk concentrates by vintage (loans made in the low-rate years face the worst repricing) and by structure (floating-rate loans feel rate moves immediately, and their maturity dates can be a moving target the manager keeps extending — deferring the wall rather than clearing it). Rate sensitivity is the companion read: how much does the refinance picture change per hundred basis points of takeout rate? A loan that flips from safe to cliff on a small rate move is a different risk than one that stays comfortable across a wide band, even if today they score the same.

Hold the whole spine together now. DSCR is the credit axis — can it cover? The maturity wall is the duration axis — can it exit? And, from the next lessons, everything macro — rates, the cycle, lending appetite — is the context that bends the exit, never a separate score. The Exit Gap and Rate Sensitivity surfaces exist to let you stand a loan in front of its own maturity and ask the second question that coverage alone will never answer: when this comes due, can it actually get out?

What the “exit gap” means A maturing fixed loan refinances into today's higher coupon. The in-place NOI is fixed, so the higher rate covers a smaller loan; the shortfall is the exit gap. The DSCR bar a loan must clear tightens by asset class. THE EXIT GAP AT A HIGHER RATE IN-PLACE NOI IS FIXED — A HIGHER TAKE-OUT COUPON BUYS A SMALLER LOAN IN-PLACE NOI (fixed) ÷ In place · 3.5% supports the current balance Refi · 6.5% supports this much refi gap Same income, higher rate → a smaller loan clears. If the gap can’t be filled with equity,the loan can’t refinance at par — rate risk transmutes into credit risk at the wall. TWO BARS PER CLASS — AND DEBT YIELD OFTEN BINDS a DSCR bar (below) AND a debt-yield floor (NOI/loan) · below a ~7.3% take-out, debt yield is the wall Multifamily · Industrial · Storage 1.25x Office · Retail 1.30x Hospitality 1.35x Deterministic:if this rate, thenthis damage — noprobabilities, everyassumption yours.

The lab

Suggested exercises

  1. Find a cliff loan. On the Exit Gap, find a loan with comfortable current coverage but a refinance DSCR below 1.0x. Write down both numbers and the takeout-rate assumption driving the gap between them. This is the loan a coverage-only reader would have called healthy.

  2. Do the adjustment by hand. Take one loan’s current DSCR and in-place rate from the Loan Browser, pick a plausible takeout rate, and compute dscr × (in-place / takeout) yourself. Confirm you can reproduce roughly what the tool shows — and feel how fast coverage erodes as the takeout rate climbs.

  3. Stress the band. On Rate Shock, walk one loan up through higher takeout rates in 100-basis-point steps and note where it crosses from safe into cliff. A loan that flips early is fragile even if it reads fine today — write one sentence on why vintage and fixed-versus-floating make some loans flip sooner than others.
