S3's leasehold loan is a bet on a document, not dirt

The land under 277 North Eighth Street stays with the Roman Catholic Church of Our Lady of Mount Carmel; what S3 Capital financed is everything the church's long-term ground lease handed the borrower: a 17-story building of 99 apartments and the right to collect rent on them.

David Grunfeld, through the entity GW Infinity, landed $45 million of construction financing for the Williamsburg project, Commercial Observer first reported. Twenty percent of the units will be designated affordable under New York City's 485-x tax incentive program, and the property sits three blocks from the Bedford Avenue L station, which puts the rental case on Manhattan access as much as on the block. The loan is a leasehold construction loan, a label that describes more of the credit than the submarket figures the lender is glad to discuss.

Shawn Safdie, S3's head of origination, called the transaction unconventional and said the loan was structured around the leasehold interest and the ground lease's terms so the borrower could proceed without the capital commitment that buying the underlying land outright would typically require. Removing land from a New York multifamily budget removes the largest upfront check, which is why developers look to parishes and other long-hold owners for infill sites. Grunfeld filed plans in December 2025 to demolish a vacant two-story building on the property, Commercial Observer reported at the time. A small vacant structure comes down, 17 stories go up, and the dirt underneath never changes hands.

Robert Schwartz, an S3 co-founder and managing principal, framed the deal as a demonstration of the firm's development background, the thing that lets S3 be "creative in structuring tailored solutions" for a project's "specific needs." What the coverage does not say is whether S3 holds the loan or distributes it, whether a mezzanine layer sits behind it, or what recourse the sponsor gave.

What is also missing is the arithmetic a credit committee would want alongside those quotes: no land value, no total project cost, no loan-to-cost, no start date, and no detail on the income bands behind the affordable units or the value of the 485-x abatement. Those are not footnotes for a construction lender: the abatement is the line in the pro forma that decides how much rent the affordable fifth of the building can forgo, and the ground lease is the document that governs the lender's cure rights, its ability to step in, and the term against which the debt has to be repaid. S3 says the loan was built around the ground lease's terms, but it does not say what those terms are, and on a leasehold loan the document is the collateral.

Safdie's most informative line is repetition: this is S3's fifth loan with this sponsorship team in this neighborhood, and five deals with one borrower in one submarket is a position in the sponsor and the ground lease more than in the rent comps, locating where a lender of S3's size believes its advantage lives.

The submarket numbers S3 cites are strong: vacancy sits near 2 percent and rents are up roughly 6 percent year over year, the firm says, against a limited pipeline of new supply. The supply half of that argument has a wider tailwind: New York City's multifamily stock is thin enough that large-building sales have been taking a bigger share of transaction volume. Morgan Stanley has separately concluded that the four-year repricing is finished and the base is forming, and a ground-up start on a land-constrained block in Brooklyn is a fair picture of what a forming base looks like.

Treat the rent statistics as the pitch and the lease as the credit. S3's claimed edge is that a lender with a development background can price a structure whose collateral is a contract rather than a deed, and the fifth loan to the same team on the same block is the closest thing to evidence that the claim travels. The concentration is also where the risk sits: recovery on this loan runs through a lease with a parish, and a lease is a thinner asset than a deed in any workout, so the terms S3 negotiated with Our Lady of Mount Carmel are the part of this transaction worth tracking, and the part the coverage does not publish.

Multifamily capital is clearing at public data points now and buyers are underwriting operations rather than rent growth, as this publication has argued. S3's stated rationale is a pair of submarket statistics and a repeat sponsor, familiar ground, but what makes a 99-unit leasehold financeable at all is a structure the public data does not price. The rent numbers get the deal into the conversation; the ground lease and the four prior loans get it closed. A lender quoting off the statistics alone is bidding on a different loan than the one S3 wrote.

The number left open is the affordable share: one in five of the 99 units carries a designation, and without the income bands or the abatement's value, nobody outside the deal can say whether the building services its debt on market rents or leans on the tax program to do it. Watch whether S3's sixth loan to this team lands on the same block, because that answer will say more about the firm's appetite for leasehold collateral than any rent statistic in this one.
