The Monologue
In June 2025, city records show three separate instruments filed against 122 Sandford Street in Brooklyn: a $2.5 million mortgage from Post Road Real Estate Finance LLC, a $65 million agreement, and a zero-dollar agreement recorded the same month. The building that secured those instruments is a 10-story, 120-unit elevator apartment building completed in 2023, sitting on a 16,167-square-foot corner lot in Bed-Stuy. Its implied market value, derived from a $9.83 million assessed value at a standard 45 percent assessment ratio, lands at roughly $21.84 million. The $65 million figure is not a typo.
That gap — between what the asset is worth on paper and what a financing structure is suggesting in capital terms — is the argument this piece makes. Something more complex than a straightforward acquisition or refi is happening at 122 Sandford. The instruments filed in June 2025 point to a structured arrangement that almost certainly involves mezzanine debt, a preferred equity stack, or a recapitalization of the underlying $17 million deed recorded in September 2021 when Myrtle Owner LLC took title. Understanding what that structure signals matters now, as Brooklyn's newly constructed multifamily assets face their first real test in a rate environment that did not exist when they were capitalized.
The Architecture of 122 Sandford Street
122 Sandford Street is a 112,091-square-foot elevator apartment building completed in 2023 following a major alteration permit filed in 2021 — which means the project was designed and financed in the frothy, low-rate window of 2020 and 2021, then delivered into a market that looked nothing like its pro forma. The building rises 10 floors on a corner lot zoned R7D, a designation that permits residential density up to a 4.66 FAR. The as-built FAR is 6.93. The building is over-built relative to its zoning by a meaningful margin, which raises a straightforward question: how did it get there? The most likely answer is a prior zoning configuration, an inclusionary housing bonus, or a development rights transfer — any of which carries its own set of regulatory and financial encumbrances that follow the deed, not the developer.
The 2021 alteration record suggests this was not a ground-up construction in the conventional sense but rather a substantial transformation of an existing structure — a development path that often obscures true cost basis and complicates future financing. A new building on paper is not always a new building in the walls. Mechanical systems, foundation constraints, and building envelope characteristics from predecessor structures can persist, creating deferred capital expenditure that a lender underwriting on certificate-of-occupancy date will miss. For a 120-unit building at 112,091 square feet, that works out to roughly 934 square feet per unit — a functional but not generous floor plate for a Brooklyn asset competing in the post-pandemic rental market against newer, amenity-rich product in Williamsburg and Greenpoint.
The Capital Stack: Brooklyn Elevator Markets, 2025–2026
City records tell a compressed story. Myrtle Owner LLC acquired the site in September 2021 for $17 million — a land or transitional basis established at peak pre-rate-hike pricing. Three and a half years later, in June 2025, the same entity filed three instruments in a single month: a $0 agreement, a $2.5 million mortgage with Post Road Real Estate Finance LLC, and a $65 million agreement. Post Road is a private bridge and transitional lender, not a long-term agency execution shop. That matters. A $2.5 million note from a bridge lender alongside a $65 million agreement is not a refinancing — it is a restructuring signal. The $65 million figure, which is roughly three times the building's implied market value of $21.84 million and nearly four times the 2021 acquisition price, most plausibly represents the notional amount of a master agreement, a credit facility, or a structured vehicle in which 122 Sandford is one pledged asset among several. Myrtle Owner LLC is the named entity here, but the capital structure almost certainly traces to a larger sponsor with a portfolio of Brooklyn transitional assets.
The assessed value of $9.83 million reflects New York City's standard lag in reassessing newly completed residential construction, which means the city has not yet caught up to stabilized income. Once it does, real estate taxes will rise — adding pressure to a debt-service calculation that is already strained by the rate environment in which this building's permanent financing must now be placed. A 120-unit building at 934 square feet per unit in Bed-Stuy, assuming market rents in the $2,800 to $3,200 range for unrestricted units, would generate gross revenues in the $4 million to $4.6 million annual range. At a 5.5 percent cap rate on a 65 percent expense ratio, stabilized NOI supports a value closer to $22 million to $26 million — consistent with the assessed value math, and nowhere near $65 million. Whatever that agreement represents, the building alone does not cover it.
The Light Tower Thesis
The conventional read on 122 Sandford is that it is a newly delivered Brooklyn multifamily asset with a clean certificate of occupancy and a decade of relatively low capital expenditure ahead of it. That read is incomplete. The June 2025 filing cluster points to a sponsor navigating a capital stack that was built for a different rate world, and Post Road's involvement suggests the permanent loan has not been placed. The window for agency execution — Freddie Mac, Fannie Mae — requires stabilized occupancy and clean debt coverage. If the building is still in lease-up, or if the existing structure has encumbrances tied to the $65 million agreement, the path to permanent financing is narrower than it looks from the outside.
A smart buyer or joint venture partner who approaches this asset in the next 12 to 18 months needs to understand exactly what that $65 million agreement encumbers before pricing equity. A smart lender needs to know whether Post Road's $2.5 million position is a protective advance or a signal that the senior debt is in technical default. These are not due-diligence footnotes — they are the transaction. Getting to that answer before the market prices it in is precisely where specialized capital advisory earns its fee.
