How Much of Your Real Estate Return Depends on Lower Rates?

A 50-basis-point change wipes out our multifamily case’s margin above the hurdle. The exit price deserves an early challenge.

By Daniel Erb

In our modeled multifamily case, increasing the exit Treasury assumption from 3.5% to 4.0% takes the return from 1.9 percentage points above our hurdle to 0.1 point below it. Income growth, recurring capital, transaction costs and the required return stay unchanged. One assumption removes the entire cushion.

For an allocator, that is a reason to challenge the sale price before getting comfortable with the sector story. A modest operating yield leaves little room for disappointment when clearing the hurdle depends on selling at richer pricing. A good property can still be a fragile investment at the wrong price.

Multifamily’s base case produces an 8.7% modeled annual return. Exit pricing contributes 1.91 percentage points, roughly the entire 1.9-point surplus over the hurdle. Almost all the headroom comes from the sale assumption. That is the part of the investment case that needs to earn your confidence.

The same rate move hits sectors differently

That 50-basis-point increase in the exit Treasury takes multifamily’s modeled return from 8.7% to 6.7%, a decline of 2.0 percentage points. Office falls from 8.6% to 7.4%, a decline of 1.2 points. In this comparison, multifamily loses considerably more return to the same change in the rate assumption.

The reason is in the exit cap rate. A property’s value equals its annual net operating income, or NOI, divided by its capitalization rate. With income unchanged, the same increase in that denominator takes a larger percentage bite from value when the cap rate starts lower. Our base case sells multifamily at a 4.73% cap rate and office at 7.85%. Adding half a percentage point has a different effect on each.

Our sensitivity moves the exit cap one for one with the exit Treasury while holding each sector’s spread assumption fixed. This isolates the valuation effect. It does not make office the better investment: office starts below its higher hurdle and remains below it after the rate change.

Across the ten sectors, seven clear their hurdles at a 3.0% exit Treasury, four at the 3.5% base case and only senior housing at 4.0%. None clears at the report’s 5.26% Treasury reference, observed September 29, 2026. The comparison uses a five-year hold, with operations, costs and hurdles fixed.

The last column measures the specific move from 3.5% to 4.0%. The effect changes at other starting rates because valuation sensitivity is nonlinear. It is a useful way to see which modeled returns absorb that change and which lose their margin.

Multifamily narrowly misses at 4.0%. Senior housing retains just 0.2 percentage point of surplus. Self-storage presents a different problem: even at a 3.0% exit Treasury, its modeled return is 4.3%, still 3.5 points below its hurdle. Within the tested range, lower rates alone do not close that gap. Advancing that case requires evidence for a better entry price, stronger operations or a different exit spread.

Last week, an illustrative calculation showed why assumptions should be visible. These Q3 results show why the distinction matters in practice. Sector fundamentals can attract your attention. The return build tells you what you are being asked to believe.

Where the multifamily return comes from

Multifamily enters our model at a 5.20% cap rate and exits at a published 4.73%. At unchanged NOI, that pricing change implies approximately 10% more value: divide 5.20 by 4.73, then subtract one. We annualize the exit effect over five years and add income growth separately.

The 5.20% entry yield is not all spendable income. Recurring capital takes 0.48 point off the top. The 2.50-point growth contribution is the report’s five-year output from a path that fades toward a sector anchor. Transaction costs take another 0.40 point, reflecting a modeled 2.0% round trip spread over five years. The exit contribution uses the fifth root of entry cap divided by exit cap, less one. Income growth does not enter that ratio a second time.

The exit cap combines three inputs: the Treasury at exit, the sector’s historical median spread and our adjustment to that spread. For multifamily, 3.5% plus a 1.43-point spread, tightened by about 20 basis points, produces the 4.73% exit cap. The tightening is our judgment: minus 0.25 times multifamily’s own spread standard deviation. A zero multiple removes that adjustment; a positive multiple widens the spread and lowers value.

The hurdle is separate. It uses the fixed 5.26% report-date Treasury plus the sector premium. Multifamily’s exact hurdle is 6.76%, displayed as 6.8%. Changing the assumed sale valuation does not change the return we require. That is why the sensitivity exposes a dependency instead of making the test easier as rates fall.

What deserves diligence next

Start with the operating return. What does the entry income yield leave after recurring capital? What supports the income growth, and what will it cost to achieve? If a renovation drives the rent increase, its capital requirement belongs in the case before the higher rent receives credit. A low purchase yield can be justified by a strong operating path, but the evidence needs to support both the improvement and its cost.

Then reset the exit Treasury against the same hurdle. For multifamily, the 4.0% case shows why this question belongs early: the base-case cushion disappears even though the operations perform exactly as assumed. Before committing more diligence time, ask what supports the price the next buyer is expected to pay.

Hold the Treasury steady and challenge the sector-view adjustment separately. Setting the multiple to zero exposes the historical-spread case. It removes the benefit where we assume tightening and the penalty where we assume widening. If the conclusion changes, focus the next discussion on evidence for that spread judgment. Changing the rate and spread together makes it harder to identify what moved the answer.

What would change our assessment is concrete: a lower entry price supported by comparable transactions and normalized NOI, a stronger income path supported by leasing evidence and a funded capital plan, or evidence that comparable assets justify tighter exit pricing. A different Treasury assumption needs its own rationale. Test those changes individually. If the only way to clear the hurdle is to keep improving the sale assumption, that dependency should be explicit in the investment decision.

For an RIA or family-office team, this is a way to allocate scarce diligence time. A case that survives the valuation test deserves a closer look at the asset and structure. A case that fails can still earn that work through a better price or a supportable operating improvement. A strong sector narrative, on its own, is not enough.

What could change the result

Lower yields are a credible outcome over five years. Inflation could ease while property income remains resilient. Leasing or occupancy could improve more than our model assumes, or an investor could buy at a better price. Those outcomes would improve the case. Falling yields can also accompany weaker rent growth, vacancies or wider property spreads, offsetting the valuation benefit. The rate table isolates one dependency; it does not forecast those relationships together.

Entry evidence also differs across sectors. Multifamily uses a broker survey, senior housing pairs a survey entry with listed-market spread history, self-storage uses a listed-market entry proxy, and single-family rentals use acquisition guidance. Check each against the assets and terms actually available. The report treats the entry bases for senior housing, single-family rentals and self-storage as provisional. A narrow modeled surplus is no substitute for that check.

Finally, clearing our hurdle does not establish client or mandate fit. Financing, fees, carried interest, taxes, liquidity and execution risk belong in the investment’s dated cash flows. Our unlevered sector comparison excludes borrowing and cannot be read as a fund’s levered or investor net return.

I would put the exit assumption near the front of the diligence conversation. When almost all the surplus depends on richer sale pricing, that assumption deserves at least as much scrutiny as the operating story. If neither the valuation evidence nor a better entry or operating case supports the return, I would spend the diligence time elsewhere.

The free Excel companion lets you change the exit Treasury and each sector-view multiple while preserving the EM hurdle. It puts the published reference beside a reconstruction from rounded inputs, with the differences visible. Use it to test which assumption changes the answer. Full current research and later sector data packs remain subscriber benefits.
