Most investment decks follow the same sequence. Executive summary. Market overview. The opportunity. Financial projections. Risk factors — somewhere near the back, after the target returns have already done their work.
That order is not accidental. It is optimized for sales, not for underwriting. And in today's Sun Belt multifamily environment, it is the wrong structure.
The stress case belongs on page one. Not because every deal is bad, but because showing what must stay true — and what happens when it doesn't — is the only way an investor can actually evaluate what they are being asked to fund.
Conservative underwriting is not a slogan
Every sponsor says they underwrite conservatively. Few define what that means.
There is a practical difference between a base case, a conservative case, and a stress case, and collapsing them into a single "conservative" projection is one of the more common ways underwriting becomes promotional.
A base case reflects management's most likely outcome given current market conditions and a competent execution of the business plan. It is a reasonable central estimate, not a ceiling.
A conservative case applies modest negative pressure — slightly higher vacancy, slightly slower rent growth, slightly wider exit cap — to test whether the deal still works if conditions are somewhat worse than expected.
A stress case is different in kind, not just degree. It asks what happens if multiple assumptions are wrong at the same time: rents are flat or negative, the exit cap is 50 to 100 basis points wider than today's market, the refinance takes longer and costs more, and capex runs over. If a deal cannot survive a plainly communicated stress case, that is not a reason to kill it automatically — but it is information an investor is entitled to have before committing capital.
CBRE's Q4 2025 multifamily underwriting survey put average core going-in cap rates at 4.75% and exit cap rates at 4.95%, with core unlevered IRR targets at 7.70%. Those are institutional benchmarks. They are not stress cases. A stress case runs the exit cap at 5.50% or 5.75% and shows the investor exactly what that does to the return stack.
Freddie Mac's Q1 2026 multifamily underwriting criteria anchor conventional financing to a maximum 80% LTV and a minimum amortized DSCR of 1.20x. If a deal's stress case cannot clear those thresholds at refinance, the investor should know before the capital ask — not during a refinance conversation two years later.
The assumptions that most often miss
Stress cases are only useful if they test the variables that actually move deals. The following are where projections most commonly diverge from outcomes in the current environment.
Exit cap rate set too tight. An exit cap assumption that closely mirrors the going-in cap embeds an implicit bet on cap rate stability or compression. In a market where rates have reset materially and transaction volume in some metros remains well below historical averages, that is not a neutral assumption. It is an optimistic one.
Rent growth reverting too slowly. A model that projects a quick return to 3% or 4% annual rent growth in Austin, Houston, or Orlando is not describing today's market. Yardi Matrix reported national advertised rents down 0.2% year over year in April 2026, with rent growth in the first four months of the year running at roughly one-third of the long-term seasonal norm. A stress case in supply-heavy submarkets should include flat to modestly negative rent growth for at least the first 12 to 18 months, not as the worst case but as a plausible base.
Vacancy and bad debt understated. In markets where concessions are active — free rent, reduced deposits, waived fees — trailing occupancy numbers can overstate the effective economic occupancy. A stress case should model vacancy and bad debt above trailing in-place levels wherever concessions are visible in the submarket.
Refinance terms modeled below current lender standards. A projection that assumes a refinance at 65% LTV and a 6.0% coupon in year five is not a stress case if current lenders are quoting 55% to 60% LTV on similar assets today. The stress case should use actual current debt terms as the floor, not the ceiling.
Texas and Florida are where generic assumptions break
National averages are a starting point. They are not an underwriting tool.
Austin absorbed a significant supply wave. Inventory reached 350,991 units at the start of 2026, with 16,171 still under construction. Yardi reported Austin advertised rents at $1,492 in January 2026, down 5.0% year over year, with occupancy at 92.3%. A stress case for an Austin asset that projects rent recovery without explicitly accounting for remaining supply delivery and concession burn is not testing the right variables.
Houston has held occupancy at 90.4% through Q1 2026, but effective rents declined year over year across all property classes. The stress case for a Houston asset needs to model continued rent softness, not a near-term inflection, and needs to show what happens to DSCR and refinance proceeds if that softness persists another 12 to 24 months.
Orlando and Tampa are working through meaningful new deliveries. Yardi reported 17,557 units under construction in Orlando, with 11,269 units — equal to 4.1% of total stock — expected to deliver in Tampa. In both markets, a stress case that does not explicitly model concession pressure and lease-up competition is testing a market that does not exist.
Miami remains the strongest Florida metro on fundamentals — Yardi reported asking rents of $2,483 with occupancy at 95.2% in January 2026. But stronger occupancy is not a license for thin exit assumptions. Insurance and operating cost pressure are real factors in every Florida market, and a stress case that does not reflect current insurance renewal realities is incomplete regardless of how healthy the rent roll looks.
How to present a stress case without overwhelming investors
A stress case does not need to be a document. It needs to be legible.
The goal is not to bury an investor in scenarios. It is to give them the information that controls the downside in a form they can actually use. That means three things:
One page of key variables. Rent growth, vacancy, exit cap, refinance terms, insurance cost assumption, tax reassessment assumption. Show the base case and the stress case side by side. Make the differences explicit.
One sensitivity table. Show how returns move as exit cap and debt cost vary independently and together. An investor who can see that a 50 basis point cap rate widening reduces the IRR from 9% to 6.5% has actionable information. An investor who only sees the 9% does not.
One plain-English paragraph on the downside. Not legal boilerplate. A direct statement of what would force a longer hold period, what would require a capital call, and what the realistic recovery path looks like in the scenario where multiple assumptions move against the plan simultaneously.
That is not a pessimistic document. It is a honest one. And it is the foundation on which investor trust is actually built — before closing, not after a distribution is missed.
The real reason the stress case gets buried
Sponsors bury the stress case because they are worried it will kill the deal. That concern is understandable. It is also a sign that the deal may need a harder look before it goes to investors.
If a plainly communicated downside scenario causes an investor to pass, one of two things is true: either the investor is wrong about the risk, or the deal does not clear the bar at honest assumptions. Both of those are useful pieces of information. Neither is served by a document that leads with target returns and saves the hard questions for the appendix.
The Federal Reserve's April 2026 Senior Loan Officer Opinion Survey reported that banks were largely holding underwriting standards steady on multifamily — not tightening dramatically, but not loosening either. That is a market where lenders are already doing their own stress work before they commit. Investors deserve the same standard.
A base case tells you what management hopes to do. A stress case tells you what the asset must survive. In today's market, that is the more important number — and it belongs at the front of the deck, not the back.
