Standing shoulder to shoulder with 782 Lexington Avenue just steps from the 59th Street–Lexington Avenue subway express hub, 780 Lexington Avenue provided the southern anchor for a $23.73 million two-building assemblage. Closed concurrently on August 27, 2026, 780 Lex Realty Associates LLC paid $10.09 million ($2,424 per square foot) to take title to the four-story mixed-use building at 780 Lexington Avenue from 780 Lex Partnership L.P., which also provided the $8.9 million seller-financed mortgage covering the assemblage. When the deed closed on August 27, 2026, 780 Lex Realty Associates LLC had officially taken down 780 Lexington Avenue from 780 Lex Partnership L.P. for $10.09 million, with Plaza District Retail Advisory brokering the trade.

At $2,424 a square foot—or $3,364,729 a door across its 2 apartments— across 4,165 square feet, the trade establishes a clean clearing mark for Lenox Hill / Plaza District 4-story retail & residential mixed-use building assets.

Why Seller Financing Is Unlocking $2,400-a-Foot Upper East Side Assemblages

The real tell in any Manhattan closing sits on the debt side of the ledger. To fund the purchase, 780 Lex Realty Associates LLC locked in a $8.9 million purchase-money assemblage mortgage from 780 Lex Partnership L.P. at 88.2 percent loan-to-value.

That loan commitment meant the buyers only needed to write a $1.19 million equity check to control a 4-story, 1900-vintage Lenox Hill / Plaza District asset. Credit committees aren't stretching to 75 percent leverage anymore, but when a sponsor brings $1.19 million of real cash equity and a basis of $2,424 a square foot, lenders like 780 Lex Partnership L.P. are wide open for business.

From Our Desk

When we look at 780 Lexington Avenue on our placement desk at Light Tower Group, the lesson for New York sponsors comes down to the marriage of entry basis and capital structure. 780 Lex Realty Associates LLC didn't try to fight the tape—they bought Lenox Hill / Plaza District footage at $2,424 a square foot and structured the stack to match the asset's timeline. When a long-term partnership rolls its equity into an $8.9 million purchase-money note to help an assembler unite 780 and 782 Lexington Avenue, both sides win: the seller collects fixed-rate interest on a prime Lenox Hill corner, and the buyer controls contiguous C5-2 frontage two blocks from Bloomingdale's.
