When the Largest Taxpayer in Town Goes to Auction

The K-shaped mall recovery is not a real estate investor story. It is a property tax story, an assessment base story, and a certiorari warning for every commercial property owner in a jurisdiction where a Class B or Class C mall anchors the tax roll. The Palisades Center foreclosure sale documents exactly what happens when that anchor collapses — and who pays.

On February 4, 2026, a 2.2 million square foot shopping mall in Rockland County, New York — one of the largest in the United States — sold at a Manhattan foreclosure auction for $175 million. There was one bidder. No competition. The buyer was the entity that already owned the debt.

The Palisades Center had been valued at $880 million in 2016. The debt it carried when it defaulted was $418.5 million, grown to $463 million with interest and costs by the time the judgment was final. A property that a decade ago supported nearly half a billion dollars in commercial mortgage financing sold, in February 2026, for less than 20 cents on the peak-value dollar.

That is the real estate story. The New York Times covered it last week in a broader piece on the K-shaped mall recovery — Class A malls thriving, Class B and C malls dying — framed around investor returns and stock prices. Simon Property Group's share price has doubled in three years. GGP's trophy properties are at 95% occupancy. The CMBS market for top-tier malls doubled from $4 billion to $8 billion in a single year.

All of that is accurate and none of it is the story that matters for the people reading this publication.

The Palisades Center is the largest taxpayer in the Town of Clarkstown, New York. It pays over $22 million per year in property taxes. When Rockland County Executive Ed Day commented publicly on the foreclosure proceedings, he did not talk about square footage or anchor tenants. He said: "It is a major tax revenue driver for the Town of Clarkstown, the school districts, and the County of Rockland."

That is the story. Not what the mall is worth to an investor. What the mall is worth to the tax base — and what happens to every other commercial property owner assessed in the same jurisdiction when that anchor goes to foreclosure, transfers to a distressed asset manager, and the new owner files its inevitable tax certiorari challenge.

The Certiorari Clock Is Already Running

Before the auction, while the foreclosure case was still in litigation, former owner Eklecco filed a tax certiorari challenge against the Town of Clarkstown. The argument was straightforward: the mall's market value was approximately $155 million, not the $578 million the town had assessed. The parties settled. Under the settlement terms, the assessed market value was set at $300 million.

Then the auction happened. Black Diamond Capital Management, which had acquired the underlying debt from Wilmington Trust in October 2025 for approximately $170 million, submitted the only bid. The property transferred at $175 million — $125 million below the settled assessed market value that Clarkstown had just negotiated.

Black Diamond is an alternative asset management firm that specializes in high yield credit, stressed and distressed credit, restructurings, and business turnarounds. It is not in the business of owning and operating shopping malls. It is in the business of acquiring distressed assets at a discount and either turning them around for resale or extracting value through restructuring. Black Diamond's founder and managing partner, Stephen Deckoff, called Palisades "an irreplaceable asset serving one of the most affluent and densely populated trade areas in the Tri-State region" — the kind of statement that suggests strategic confidence in the property's location, not necessarily in its current operating model.

What this new owner's cost basis means for property taxes is not ambiguous. Black Diamond acquired the debt for approximately $170 million. It credit-bid $175 million at auction to take title. Its all-in basis on a 2.2 million square foot, 172-acre property in Rockland County is roughly $175 million. The property is currently assessed as though it is worth $300 million — $125 million more than the transaction price the auction market just established as its actual value.

The certiorari challenge is not speculative. It is the rational economic response of any property owner who can document that its assessed value materially exceeds its actual market value. The February 4 auction, conducted in open court, with no competing bids, is the most unambiguous arms-length market evidence available. Black Diamond's attorneys will use it.

The question for Clarkstown, for the school districts, and for Rockland County is not whether a new challenge comes. It is how large the reassessment is, how quickly it takes effect, and who absorbs the $22 million annual tax revenue gap that results.

For commercial property owners assessed in Clarkstown and across Rockland County, that last question is not rhetorical. When a jurisdiction's largest taxpayer successfully argues its assessed value down by a substantial amount, the adjustment does not disappear from the tax roll. It redistributes. The jurisdiction's revenue needs do not shrink because one property's assessed value did. The burden shifts.

How Mall Values Collapse: The Mechanics That Produce This Outcome

Understanding why the Palisades Center's value trajectory looks the way it does requires a short history of how the Class B and Class C mall death spiral operates in practice — because the Palisades case is not unusual. It is the median case for the bottom half of the American mall market, playing out at larger scale and closer to a major metropolitan area than most.

The Palisades Center opened in 1998 on a 130-acre site that previously housed two landfills in West Nyack. At its peak it drew more than 20 million annual shoppers, boasted a Nancy Kerrigan-inaugurated ice rink, and was anchored by department stores including JCPenney and Lord & Taylor. The mortgage it carried — $418.5 million originated in 2016 — was the financial expression of its early-2000s peak valuation of over $880 million. The debt was sized to its then-current income-producing capacity.

What happened next is well-documented in both the Palisades case and across the Class B/C mall universe. JCPenney filed for bankruptcy. Lord & Taylor filed for bankruptcy. The anchor boxes — which in the traditional mall model drove foot traffic that justified the inline tenant rents that serviced the debt — went dark. Inline tenants, whose leases were typically tied to co-tenancy clauses protecting them from paying full rent without functioning anchors, exercised those clauses. Rent revenue declined. The property's income-based appraised value declined faster than the assessed value did. The gap between what the mall was actually worth to a buyer on an income-approach basis and what the town was assessing it at widened steadily through the pandemic years and beyond.

The income approach to commercial real estate valuation — capitalized net operating income divided by market cap rate — is mechanically brutal in this environment. A property with declining rents, rising vacancy, and deteriorating anchor presence produces lower NOI every year. When cap rates for distressed retail also rise, reflecting the market's higher risk perception, the combination of lower NOI and higher cap rates compresses appraised value faster than any other commercial property type in the current environment. A property with $15 million annual NOI capitalized at 7% is worth $214 million. The same property with $12 million NOI capitalized at 9% is worth $133 million. Neither requires the building to change physically. Both reflect what actually happened to Class B/C mall income over the past decade.

The Palisades Center's visitor count declined from over 20 million at peak to approximately 16 million by the time of the foreclosure — a 20% drop that translated directly into lower tenant sales, lower percentage rents, more co-tenancy clause exercises, and a deteriorating spiral that the debt load made impossible to interrupt through capital investment.

By 2023, when Wilmington Trust filed the foreclosure action, the gap between the debt and the property's recoverable value was already clear. By the time the auction was held, no investor other than the existing debt holder saw sufficient value to submit a competing bid at any price above $175 million.

This is not a singular event. The New York Times reports approximately 40 mall closures per year in the United States. It reports that 11.2% of the $53.23 billion in loans backed by regional and super-regional malls are currently delinquent. Three major mall property owners — CBL Properties, Washington Prime Group, and Pennsylvania Real Estate Investment Trust — declared bankruptcy between 2020 and 2023. The Palisades Center is one data point in a continuing national series.

The Assessment Base Problem: Who Pays When the Anchor Falls

Every commercial property owner reading this piece should understand the mechanics of what happens to a local tax base when its largest assessed taxpayer undergoes a foreclosure sale that establishes a transaction price far below the current assessed value.

Property tax is not a fixed dollar obligation. It is a rate applied to assessed value. Jurisdictions set their levy — the total dollars they need to fund services — and then divide that levy across the assessed value of all taxable properties in the jurisdiction. When a single large property's assessed value declines, through successful certiorari challenge or through a revised assessment following a transaction, the total assessed value in the jurisdiction shrinks. If the levy remains constant, the rate must increase to produce the same revenue. Or the levy decreases — meaning services are cut. Either outcome falls on the remaining assessment base.

In Clarkstown, the Palisades Center paying over $22 million per year in property taxes means it represents a substantial fraction of the town's total commercial property tax revenue. The mall sits on 172 acres and encompasses 2.2 million square feet. No other single commercial property in Clarkstown is likely within an order of magnitude of that tax contribution.

When Black Diamond's certiorari challenge reduces the mall's assessed value from $300 million toward something closer to its $175 million transaction price, the mechanics operate as follows. The town's levy does not automatically shrink by $22 million, because the town has not suddenly stopped needing to fund schools, roads, and services. The levy adjusts at the margins. But the assessed value supporting that levy has contracted significantly on the mall parcel. Every other commercial and residential taxpayer in Clarkstown now supports a slightly larger share of the remaining levy than they did before.

For commercial property owners in Clarkstown and across Rockland County whose own assessments are calculated as a percentage of market value, there is a secondary effect that is less mechanical but equally real. Assessors and courts use comparable sales when evaluating commercial property certiorari challenges. The Palisades Center transaction at $175 million on a $300 million assessed value is now a data point in the comparable sales record for Rockland County commercial real estate. Other commercial property owners in the county whose assessments are being challenged — or who are considering filing challenges — now have a transaction establishing that a 40%+ gap between assessed value and arms-length market price is legally supportable in this jurisdiction.

That comparable is not limited to mall properties. Any income-producing commercial property in a jurisdiction near a major distressed mall transaction has a new data point to use when arguing that its assessment is excessive relative to its income-approach value.

The K-Shape and Your Assessment Roll

The New York Times describes the mall market's K-shaped recovery in terms that are useful but incomplete for property owners and district managers. The top 100 malls account for 50% of the sector's total value, according to Green Street analytics. The bottom 350 account for 10%. Class A mall revenue is growing at 5% annually. Class B and C mall revenue is shrinking at 5% annually. The CMBS delinquency rate for the Class B/C tier is 11.2%.

Translated into assessment terms: roughly 350 malls in the United States are in active value decline, and the jurisdictions where those malls constitute a significant fraction of the commercial property tax base are absorbing that decline in one of two ways — either through reassessment, which shifts burden to other taxpayers, or through deferred reassessment, which creates a growing gap between assessed values and market values that eventually corrects through certiorari challenges, foreclosure transactions, or forced reassessment cycles.

Neither correction is invisible to commercial property owners in those jurisdictions. Both produce redistribution of the tax burden.

For property owners who own commercial assets in jurisdictions with distressed Class B/C mall properties, the actionable question is straightforward: does your assessed value reflect market conditions accurately, and is the assessed value of the mall that anchors your local tax base likely to decrease substantially in the near term? If both answers point the same direction — your assessment is accurate or slightly high, and the mall's assessment is going to be challenged down — the relative burden in your jurisdiction is moving in a direction that disadvantages you, regardless of what happens to your specific property.

Class A mall adjacency produces the opposite condition. Simon Property Group's Roosevelt Field is 96.3% occupied, producing $1,250 per square foot in tenant sales, and financing Class A mall CMBS at doubled volume. Its assessed value is stable or appreciating. The jurisdictions that host Class A mall properties have a large, growing, stable commercial assessed value anchoring their tax rolls — which exerts downward pressure on rates for every other property in the jurisdiction.

The same property, different zip code, different tax dynamics entirely.

The Clarkstown Case in Detail

The Palisades Center situation in Clarkstown is instructive because the public record is unusually complete.

Former owner Eklecco, in its pre-auction tax certiorari challenge, argued a market value of approximately $155 million. The Town of Clarkstown argued $578 million. The gap — $423 million between owner and jurisdiction on a single property — reflects how wide the divergence between income-approach appraisal and assessment practice can become when a distressed property's cash flow has deteriorated but the assessment has not been updated at the same pace.

The settlement at $300 million was a compromise that neither side was entirely satisfied with, and which Black Diamond's $175 million auction bid has now rendered arguably obsolete as a market-based indicator. The settlement was negotiated against a background of ongoing litigation, uncertain auction outcomes, and the transaction risk inherent in any distressed property process. The auction result removes that uncertainty. $175 million, sole bidder, no competing offers, in open court — this is as clean a market price signal as the property assessment system ever receives.

Clarkstown's assessor now faces a decision that assessors in dozens of jurisdictions are facing or will face in the next 18 months as the Class B/C mall foreclosure cycle continues: does the assessment reflect the new transaction price, and if so, how quickly?

State law governs the reassessment timeline. New York's assessment cycle means that properties are assessed as of a specific valuation date, and certiorari challenges operate on a lag. Black Diamond can file a new certiorari challenge for the tax year that reflects conditions as of the valuation date closest to the auction. In jurisdictions where the valuation date is January 1, a February 4 auction is nearly perfectly timed to establish market value for the following tax year's assessment.

The $22 million annual tax figure that Rockland County Executive Day cited is the number that frames this for local government. It also frames it for every other taxpayer in the county. That $22 million does not disappear from the county's revenue needs because the mall changed hands at a fraction of its prior assessed value.

What Property Owners Should Do Right Now

The Palisades Center situation is specific to Rockland County but the pattern is national, and the actions that commercial property owners should be taking in response to it are the same regardless of jurisdiction.

Identify the major assessed commercial properties in your jurisdiction. In most jurisdictions, the top 10 assessed taxpayers are a matter of public record — assessors publish these lists, and they are available through local government websites or open records requests. If a Class B or C mall is on that list, or if a major single-tenant retail property, a distressed office campus, or any other large commercial property that has experienced significant value decline is on that list, your jurisdiction's assessment base has structural exposure to the reassessment cycle. Understanding that exposure before it produces a rate adjustment — rather than after — is the difference between planning for it and reacting to it.

Review your own assessment for accuracy. When the largest commercial property in a jurisdiction is successfully challenged down, the comparable sales record shifts. If your property is assessed at a level that the current income approach and comparable sales data cannot support, the window to file a certiorari challenge uses tight statutory deadlines. In New York, certiorari challenges must be filed within 30 days of the filing of the assessment roll. Missing the deadline forecloses the challenge entirely. Knowing where you stand requires reviewing your current assessment against a current income-approach appraisal, not against what the property was worth when it was last formally reviewed.

Understand your lease co-tenancy exposure. If you own commercial property whose tenants have co-tenancy clauses in their leases — protections that reduce rent obligations or allow termination if anchor tenants or minimum occupancy thresholds aren't met — and if your corridor or shopping area is adjacent to a Class B or C mall in the deterioration phase, those clauses represent a direct link between the mall's decline and your own income-based property value. The income approach assessors and appraisers use reflects actual rent rolls, not contract rents that tenants are exercising clauses to reduce. When your anchor-dependent tenants exercise co-tenancy provisions, your NOI goes down. When your NOI goes down, your income-approach value goes down. When your income-approach value goes down below your current assessment, you have a certiorari case.

Model the rate impact. If your jurisdiction's largest assessed commercial property is undergoing a major value correction, the rate impact on remaining taxpayers is calculable. Your jurisdiction's total assessed value and total levy are matters of public record, typically published in annual budget documents and assessor reports. With those numbers and an estimate of how much the distressed property's assessment is likely to decline, you can model the approximate rate increase that remaining taxpayers will absorb. That calculation is worth doing before the budget cycle produces it as a surprise.

Talk to your district manager. For commercial property owners in BID or CID districts, the assessment question has a second dimension. Districts whose assessment formulas are based on property values — assessed value as the rate base — will see their district levy exposure move in the same direction as the municipal assessment. A declining assessed value for your property means a lower district assessment in a value-based formula district. But a rising rate applied to a declining base can produce an assessment that is a higher percentage of your total property tax obligation than it was before. Understanding how your district's formula interacts with municipal assessment changes is a budget management question that is worth raising with your district manager before the reassessment produces an unexpected result.

The Redevelopment Wildcard

Palisades Center's future is genuinely uncertain. Black Diamond has expressed commitment to investment. Local real estate observers have suggested possible futures including hotel and convention center development, residential rezoning of the vacant anchor boxes, or continued operation with a repositioned tenant mix oriented toward experiential retail, dining, and entertainment — the model that the New York Times documents Class A operators using successfully.

The redevelopment question matters for adjacent commercial property owners in a way that is separate from the assessment question. A 172-acre site in Rockland County, 30 miles from Manhattan, that transitions from a traditional enclosed mall format into a mixed-use development including residential, hospitality, and experiential retail is a fundamentally different commercial neighbor than either the peak-era destination mall or the distressed, partially-dark mall in decline. Each transition creates different demand patterns for adjacent corridors.

A residential conversion on the anchor boxes, for example, would add permanent daily population to the trade area — residents who need grocery, service, and food and beverage within walking or short driving distance, on weekdays as well as weekends, on ordinary days as well as event days. That is a demand pattern that benefits certain types of corridor businesses more than the event-driven foot traffic the traditional mall model produced. Service businesses, neighborhood food and beverage, personal care — these are different beneficiaries than the specialty retail that mall adjacency historically supported.

A hotel and convention center addition would produce a different demand pattern still — high weekday business travel, corporate dining, event-driven weekend peaks — that requires its own set of corridor services and retail amenities.

The common thread is that major retail property redevelopment changes the demand environment for adjacent commercial corridors in ways that the current lease structures, tenant mixes, and capital investment decisions of adjacent property owners may not be positioned to capture. Property owners within several miles of the Palisades Center should be following Black Diamond's redevelopment statements closely — not because the statements are necessarily reliable at this stage, but because the direction they indicate will determine what kind of demand arrives at the site when the redevelopment eventually comes.

Clarkstown town officials are already moving in an anticipatory direction. Local planning conversations have been exploring live/work/play developments near transit as the dominant land use vision for the corridor's future. That planning context will shape what Black Diamond can actually build, and what it builds will shape the commercial environment within which adjacent property owners are operating for the next 20 years.

The National Pattern

The Palisades Center is one instance of a pattern that is repeating at roughly 40 sites per year across the United States. The CBL Properties bankruptcy in 2020, the Washington Prime Group bankruptcy in 2021, the Pennsylvania Real Estate Investment Trust bankruptcy in 2023 — each of these proceedings involved multiple mall properties in multiple jurisdictions, each of which went through some version of the value correction, certiorari challenge, and assessment base redistribution cycle that Clarkstown is now entering.

The properties affected are not randomly distributed. They cluster in mid-size metros, suburban ring communities, and secondary markets where the Class A mall premium never fully materialized but where the debt structures of the 1990s and 2000s were sized as though it would. The jurisdictions where these properties anchor the commercial tax base are, correspondingly, mid-size suburban municipalities whose financial planning assumed a level of commercial property tax revenue that the actual market can no longer support.

For commercial property owners in those jurisdictions, the strategic posture that the Clarkstown situation recommends is not passive. The assessment base dynamics are moving in a direction that redistributes burden regardless of what happens to any individual property. The certiorari deadlines are real. The comparable sales record is being reset with every foreclosure transaction. The income approach valuations that assessors, courts, and lenders use are capturing a deteriorating income reality in real time.

The property owners who emerge from this cycle with their assessment obligations calibrated to their actual property values — rather than to the peak-era values the assessment rolls in many jurisdictions still reflect — are the ones who engaged the process proactively, filed their challenges on time, and had current appraisals in hand when the comparable sales evidence became favorable.

The Palisades Center auction created favorable comparable sales evidence for every Class B/C mall-adjacent commercial property owner in the northeastern United States. That evidence has a statutory shelf life that depends on the jurisdiction's certiorari filing deadlines.

Don't wait for the reassessment notice to find out what those deadlines are.
