One of the most influential analyses on the question of fixed versus floating interest rates comes from the advisory firm Pensford. It examines how often, historically, it would have paid off to choose floating instead of fixed rates.
The result is striking: borrowers with floating rates paid less on average—and the longer the term, the more pronounced the advantage became.
At first glance, this seems logical. Markets regularly overestimate future interest rate hikes. Those who stick with floating-rate financing therefore often benefit from the fact that the actual trajectory of interest rates turns out to be less severe than initially expected.
This, however, is exactly where the practical problem begins. Because this analysis does not automatically show what real estate borrowers actually pay under real market conditions. It compares interest rate expectations and historical benchmarks, but not the specific structure of real-world financing. And it is precisely from this that recommendations often emerge which fall short in practice.
The Missing Piece of the Puzzle: Index Plus Spread
To understand the weakness of such historical interest rate comparisons, one first has to look at how financing costs are actually formed in practice. A loan interest rate is never just a market rate. It always consists of two building blocks: index and spread.
The index is the underlying benchmark rate that a floating-rate loan is based on—in the U.S. today, this is typically SOFR, the Secured Overnight Financing Rate. Simply put, this is a market interest rate for very short-term financing secured by U.S. Treasuries. LIBOR used to be the dominant benchmark rate in the U.S. dollar market, but has played no role since its discontinuation on June 30, 2023.
The spread is the risk premium that the lender demands on top, pricing in not just general interest costs but the specific risk of the financing: the quality of the property, the strength of the sponsor, the market environment, and the refinancing risk. A borrower, therefore, never pays just the index, but always index plus spread.
This is exactly where the significance of purely historical fixed-vs.-floating comparisons reaches its limits. Pensford essentially looks at the trajectory of the benchmark rate and shows that floating-rate financing often appeared cheaper historically based on this. As an observation, this is not wrong. For real estate financing, however, it is not enough. Because in practice, it is not only the benchmark rate that decides the outcome, but above all how highly the market prices the respective risk.
A bridge loan, for example, might sit at SOFR plus 450 basis points, while an agency loan as a long-term fixed rate is calculated in a completely different cost and risk logic. As soon as these spreads shift, it is not just the price of a financing that changes, but its entire risk profile.
And that is exactly why the classic question of “fixed or floating?” often falls short. Those who only compare the expected path of interest rates are comparing prices—but not necessarily the resilience of the capital structure. What matters is not only what a loan costs today, but whether it remains viable when risk premiums, liquidity, and refinancing conditions change.
What Really Happened in the Financing Market in 2022
In the spring of 2022, the Federal Reserve began its fastest rate-hiking cycle in decades. The relevant benchmark rate rose by 530 basis points in a short period of time, from near zero to over five percent. That alone was a significant burden for many financing structures.
Crucially, however, it did not stop there. Parallel to the rise in interest rates, risk perception in the bridge lending market also shifted. Lenders suddenly demanded significantly higher premiums for the same type of loan. Bridge spreads, which previously often hovered around 150 basis points, widened to 400 to 500 basis points.
So while the index rose by 530 basis points, the total cost for bridge-financed properties climbed by nearly 700 basis points. The additional 170-basis-point spread shock came on top, making the situation exponentially worse than the pure index movement alone. This is exactly where Pensford’s historical logic hits its limit.
The analysis convincingly shows that floating-rate financing was often cheaper than fixed rates over long periods regarding the index. For today’s market, however, that is no longer sufficient. Because real estate financing is not determined by the benchmark rate alone, but by index plus spread. When both rise simultaneously, a calculable interest rate hike turns into a much deeper structural rupture.
Therefore, 2022 was not simply a year of higher interest rates. It was a market regime shift. While the index rose, risk premiums were simultaneously repriced. A historical analysis looking at a different market regime can only capture this dual effect to a limited extent. For investors, this is the real lesson: it is not just the direction of interest rates that has changed, but the mechanics of financing itself.
The Tides Equities Case: Why Floating Debt Became a Structural Trap
Tides Equities is so revealing for the fixed versus floating debate because the case shows that it is not just the interest rate itself that matters, but the entire logic of the financing.
Tides bought multifamily properties in Sun Belt markets, financed the renovation phase with cheap bridge loans, and bet on either selling the assets profitably after driving rent growth or transitioning them into long-term financing.
In a market with cheap debt, strong rent growth, and an open refinancing window, this was plausible. Between 2021 and 2022, Tides built a portfolio of over $6.5 billion at breakneck speed this way.
Then the regime flipped. At the Tides on Haverwood property in Dallas, the monthly interest burden rose from around $150,000 to approximately $250,000. This left properties that had generated positive cash flows under low financing costs economically highly vulnerable. The higher debt service devoured the buffer the model needed to sustain the renovation, the holding period, and the subsequent refinancing.
But the problem did not end there. At the same time, the market side of the business plan also came under pressure. A massive wave of new supply hit the market in the Sun Belt, rent growth cooled, and valuations came under pressure. As a result, strategies like Tides saw not only their cost side collapse, but also their revenue and exit side.
This is exactly what became the structural trap. The properties were supposed to be transitioned into long-term financing or a sale after renovation. Instead, Tides encountered a market where the ongoing debt service had climbed, expected rent growth failed to materialize, and collateral lost value. Debt became more expensive while the real estate meant to support that debt became weaker. This is no longer a mere misforecast on interest rates. This is a breakdown of the entire financing logic.
The consequences were concrete. In 2023, Tides informed its investors that parts of the portfolio were in financial distress and required additional capital. In 2024, the company attempted to raise new preferred equity. For existing investors, this effectively meant massive economic dilution. Furthermore, lenders such as Starwood sued the management for the repayment of personal guarantees. In early 2025, Haverwood went back to the lender after a default.
The path thus led not only to higher interest costs, but to cash-negative properties, equity dilution, asset losses, and ultimately even personal liability from guarantees. The end of the story, then, was not merely tighter cash flow, but the visible unraveling of a capital structure that offered no buffer for unforeseen market shifts.
And therein lies the lesson of the case. Had a stabilized property been transitioned into a long-term agency loan in time—meaning a typically fixed-rate loan through the multifamily programs of Fannie Mae or Freddie Mac, as are commonly used for stabilized residential assets in the U.S.—the subsequent tightening cycle would have been far less destructive. The crucial difference, therefore, is not whether one predicted interest rates correctly. It lies in the question of which structure continues to hold up even when rates rise, spreads widen, rents disappoint, and the exit market weakens. Structure beats forecast.
The Invisible Regime Shift: Why Historical Data Offers Only Limited Help Today
Pensford’s analysis describes a market regime that actually worked for a long time. From the 1990s until around 2021, bridge loans were a rational alternative to agency financing for many investors. Spreads were tight, total costs often similar, and the greater flexibility argued for the short-term, floating structure in many value-add strategies.
This historical observation itself is not wrong. It only becomes problematic when a broad recommendation for today’s market is derived from it. Because since 2021, it is not just the level of interest rates that has changed. The entire pricing logic of the financing market has shifted.
Bridge loans price in uncertainty much more aggressively today than they did in the old regime. Lenders demand higher premiums not only for the interest rate risk itself, but also for refinancing risk, exit risk, and the reduced visibility of future cash flows. That is why bridge spreads have widened from often around 150 basis points in the past to roughly 400 to 500 basis points.
For agency financing, the trajectory moved in the opposite direction. Fannie Mae and Freddie Mac were able to operate more aggressively again in the market for stabilized multifamily properties, allowing them to offer more attractive terms relative to bridge loans. This is exactly where the real shift lies: for many stabilized properties, agency debt today is not only more predictable and secure, but often cheaper than floating bridge debt.
For a stabilized multifamily asset, this can currently mean the difference between long-term fixed-rate financing in the range of roughly 5.0 to 6.0 percent and variable bridge financing at around 8 to 9 percent. This translates to a gap of approximately 200 to 300 basis points. On a $15 million loan, that means roughly $300,000 more in annual interest costs—or about $900,000 over three years.
This is precisely why Pensford can only capture this shift to a limited extent in its historical analysis. The analysis is based on data from a market where flexibility could be had cheaply. Today, that flexibility must be paid for with significantly higher risk premiums. Pensford is therefore not describing a false past, but a past whose pricing logic no longer applies to many of today’s decisions.
For today’s investors, it is therefore no longer enough to point to the historical outperformance of floating-rate financing. What matters is not what made floating cheaper on average in the past. What matters is which capital structure remains viable in today’s market even when spreads widen, liquidity tightens, and refinancing can no longer be treated as a guaranteed stepping stone.
The Wrong Question and the Right Answer
Following the market shift since 2021, the classic question of “fixed or floating?” is often misleading. It sounds precise, but in many cases, it is too superficial. Because it pretends that the main issue is accurately predicting the future path of interest rates. In reality, it is about something else entirely: Which financing structure fits the condition of the property—and remains viable even if the market turns against the original plan?
That is exactly why the crucial dividing line today is not only between fixed and floating, but also between transitional financing and permanent financing. Bridge loans continue to have their place when a property is not yet stabilized, when it needs to be renovated, repositioned, or operationally overhauled, or when a short-term opportunity needs to be financed. In such cases, floating debt is not wrong. It is part of a transitional structure.
The situation is different for stabilized multifamily properties. Once an asset is in a condition where long-term capital would be available, the question changes. Then it is no longer about whether an investor can theoretically still hope for lower floating rates. Then the question becomes why they should bear any additional refinancing and market pricing risk at all, when long-term, mostly fixed-rate agency financing is available through Fannie Mae or Freddie Mac programs. Precisely at this stage, agency debt today is often not just safer, but also cheaper than floating bridge financing.
This is the real break from the old fixed-vs.-floating debate. Floating is not fundamentally wrong. But for stabilized assets, it is no longer a neutral default choice. Those who still opt for floating debt at this stage are consciously taking on additional risk—and today are often not even compensated with lower running costs for doing so.
Even hedges like interest rate caps only alter this to a limited degree. They can partially cap the rise in the benchmark rate. They do not, however, solve the underlying problem when spreads widen, refinancing becomes tougher, or the exit market softens at the same time. That is exactly where it is decided whether a structure is robust or not.
The right question is therefore no longer: Was floating historically often cheaper than fixed? The right question is: Is my property already stabilized, is long-term capital available, and does the business plan remain viable even if I cannot rely on a favorable refinancing window? Where these questions can be answered with yes, a long-term fixed-rate structure is generally the superior solution today. Where they must be answered with no, bridge financing can still make sense—but specifically as a deliberate transitional instrument, not as supposedly free flexibility.
The Practical Example: How the Same Property Looks Completely Different Under Two Financings
Let us take a stabilized multifamily asset valued at $15 million with a cap rate of 6.6% (i.e., a property yield of 6.6% before financing costs). This translates to an annual NOI of roughly $990,000. It is exactly in this example that it becomes clear why not just the interest rate matters, but the structure of the financing.
If the property is financed with a bridge loan at an all-in cost of roughly 8.5% and 70% LTV (Loan-to-Value, the ratio of the loan to the property value), the loan amount is $10.5 million. The annual interest burden then totals around $892,500. Out of the nearly $990,000 in NOI, this leaves a buffer of only about $97,500. This means: while the property is still financeable, almost any operational setback immediately becomes a problem. Even slightly weaker rents, slightly higher expenses, or a more difficult takeout financing can derail the case.
With bridge financing, LTC (Loan-to-Cost, the ratio of the loan to total project costs) also often plays a role in practice. This metric is particularly important in value-add strategies because it is not just the property value that counts, but how heavily the acquisition, renovation, and holding period are leveraged with debt overall. For this example featuring an already stabilized asset, however, LTV is the more appropriate benchmark.
If the same property is instead financed with an agency loan at roughly 5.5% fixed and 65% LTV, the loan amount comes to $9.75 million. The annual interest burden then totals around $536,250. The remaining cash flow sits at roughly $453,750. At the same time, the DSCR (Debt Service Coverage Ratio, the ratio of NOI to debt service) sits at about 1.85, well above the typical minimum requirement of 1.3. This means: The property supports its financing not just on paper, but with visible margin.
| Metric | Bridge Financing | Agency Financing |
|---|---|---|
| Property Value | $15.0 million | $15.0 million |
| Cap Rate | 6.6% | 6.6% |
| Annual NOI | $990,000 | $990,000 |
| LTV | 70% | 65% |
| Loan Amount | $10.5 million | $9.75 million |
| Interest Rate / All-in Cost | 8.5% floating | 5.5% fixed |
| Annual Interest Burden | $892,500 | $536,250 |
| Remaining Cash Flow | $97,500 | $453,750 |
| DSCR | approx. 1.11 | approx. 1.85 |
| Structural Implication | minimal buffer | clear resilience |
This does not even fully describe the real difference. If floating financing costs continue to rise, the situation for bridge debt tightens immediately, while agency debt remains unchanged. If the cost of bridge financing rises by another two percentage points, the annual interest burden climbs to roughly $1.10 million. Debt service would then exceed the annual NOI of $990,000. The asset would thus not merely be stressed, but no longer sustainable from its ongoing income.
Under agency financing, on the other hand, the annual interest burden would remain at $536,250. This is precisely where the structural difference shows itself: one financing worsens with every further rate movement, while the other stabilizes the case. This is more than the difference between slightly more expensive and slightly cheaper financing. It is the difference between a structure that can absorb fluctuations and one that loses its viability under further stress. Bridge debt is therefore not just temporarily more expensive in this example. It is structurally more fragile and clearly riskier under further interest rate pressure.
The fact that agency debt operates here with a slightly lower LTV is not a flaw of the example, but part of the message. The structure requires more equity, but rewards this with a substantially lower interest burden, better cash flow, and significantly reduced refinancing risk.
Why Spreads Explode During Crises
To understand today’s market, one must also understand why bridge spreads spike so sharply during periods of stress. This is not an overreaction by lenders, but the consequence of a business model that finances transitional risks.
Bridge lenders generally operate as generalist lenders. They lend against real estate as collateral, but care far less about the long-term operational performance. They mostly finance assets that are not yet fully stabilized or whose business plan relies on renovation, repositioning, sale, or future refinancing. Their loans typically run for only two to three years. Repayment therefore often depends not solely on ongoing cash flow, but on the borrower being able to sell or shift into long-term financing in time.
And therein lies the vulnerability of this structure. When this refinancing window closes—because rates rise, valuations fall, or credit markets tighten—the risk materializes on the lenders’ side. They do not simply extend more expensive loans at that point. They end up in situations where they have to take over properties, manage them, sell them at a discount, or work through legal disputes. These experiences are subsequently baked into the pricing of new loans. That is why spreads do not widen randomly in crises, but as a direct reaction to real losses and repriced risks.
This is exactly what could be observed following cases like Tides. The market has learned that short-term, floating debt contains not just interest rate risk, but a combined potential for exit failure, refinancing hurdles, and capital loss. The result was not a theoretical reassessment, but tangibly harsher pricing for new bridge loans.
For agency financing, the logic is different. They typically finance stabilized multifamily properties over longer terms of five, ten, or more years. What matters there is not the near-term refinancing window, but the enduring quality of the asset and its ability to carry long-term debt service. That is precisely why agency spreads generally remain more stable and tighter than bridge spreads. The critical point, therefore, is: Bridge does not become more expensive in crises because lenders act opportunistically, but because the product itself is far more prone to losses during periods of stress. And that is exactly why a historical analysis looking only at benchmark rates can capture the reality of today’s market only incompletely.
The Inconvenient Truth
Pensford’s analysis highlighted an important point: markets tend to overestimate future rate hikes. As a historical observation, this is valuable. On its own, however, it is no longer sufficient today. Because between a world of tight spreads and a world of wide spreads, it is not just prices that change. It also changes which financing makes sense for the same property.
In a market with tight spreads, floating debt was rational and often right for many investors. Bridge debt did not cost significantly more than agency debt, but offered greater flexibility. In that world, the historical Pensford argument held up: if floating-rate financing was often cheaper on average and the premium for flexibility remained manageable, floating was the appropriate structure in many cases.
In a market with wide spreads, this logic fundamentally shifts. Then the investor is no longer paying just for flexibility, but for significantly higher refinancing, exit, and market pricing risk. In this environment, bridge becomes not just more expensive than agency, but often structurally more fragile. This is exactly why the same historical observation leads to different conclusions in two different market regimes.
Herein lies the deeper flaw of the classic fixed-vs.-floating debate. It ignores not only that spreads exist. It also ignores that spreads themselves are cyclical, regime-dependent, and often more critical to the decision than the pure benchmark rate. A statistic spanning the last 30 years can therefore be helpful—but only as long as one does not overlook the fact that the pricing logic of the market has fundamentally shifted in recent years.
The inconvenient truth is thus: Pensford is not describing a false past. But this past no longer automatically provides the right answer for the present.
The Real Decision
After all this, the central question remains surprisingly simple. For a stabilized multifamily property, the issue today is no longer whether floating debt was historically often cheaper. The issue is whether there is a good reason to pay even more for a more fragile structure.
That is exactly what is frequently happening today. For stabilized assets, bridge financing is often not only more expensive than agency financing, but brings with it additional refinancing, spread, and market pricing risk. The former advantage of flexibility no longer holds when that flexibility suddenly costs a hefty premium.
This does not mean that bridge loans have disappeared. They continue to have their place—but where they belong: in genuine transitional situations. If a property is not yet stabilized, if it needs renovation or repositioning, and if a swift, realistic exit is actually part of the business plan, bridge can still make sense.
For stabilized assets, however, the situation has fundamentally changed. There, floating debt today is often no longer an elegant form of flexibility, but the deliberate assumption of additional risk that is frequently not even rewarded with lower costs anymore.
This is exactly where the practical consequence lies. The old question of “fixed or floating?” falls short. The crucial question is: Does this property really need transitional financing—or is an unnecessary refinancing risk simply being underwritten here?
The Tides Equities case shows how this confusion actually ends. What began as an efficient use of floating-rate financing led first to cash-negative properties, capital calls, and the search for new preferred equity. This was followed by foreclosures, the loss of individual properties—including Tides on Haverwood in early January 2025—and ultimately even personal liability from guarantees. The end of the story was thus not merely a tighter cash flow, but the visible unraveling of a capital structure that only worked as long as refinancing, rent growth, and the exit market played along.
What Follows From This?
The true shift of this market cycle does not lie in the fact that interest rates have risen. It lies in the fact that an entire generation of investors had to learn how differently the same financing behaves in different market regimes.
For many years, floating-rate financing for multifamily properties was often a sensible decision. It was flexible, competitively priced, and worked in a market where refinancing was seen almost as a standard next step. That specific world is over.
Today, the question is therefore no longer whether floating was frequently cheaper on historical average. The question is whether there is a compelling reason to choose a more fragile structure for a stabilized asset, one that often costs even more than the long-term alternative.
This also shifts the yardstick for a good financing decision. It is not the bolder interest rate call that convinces, but the more resilient capital structure. A financing structure proves its quality not in the base case, but the moment the market no longer validates the original plan. This is the real lesson of this cycle: Anyone still primarily debating fixed versus floating for stabilized multifamily properties today is often already asking the wrong question. What matters is whether the chosen structure continues to hold up even when hope fails to turn into a refinancing.
The Consequence for Portfolio Structure
Our investment philosophy at Whitestone Capital is derived from exactly these market mechanics.
When experience shows that the resilience of the capital structure during periods of stress is more critical than pure interest rate forecasting, a strictly structure-oriented approach takes center stage.
For multifamily assets in Florida, this specifically means prioritizing the value of enduring resilience over the supposed flexibility of short-term constructs. By securing the foundation through long-term, crisis-resistant models—such as agency financing—we deliberately insulate cash flow from the volatility of interest rate and spread fluctuations.
In the end, reliable wealth creation is not based on perfectly timing the market, but on structuring the portfolio from the outset so that it functions predictably in any conceivable market regime.
