How We Measure
Methodology
Every statistic published on sky-nyc.com ties back to a verifiable source. This page documents how we calculate closed volume, submarket cap rates, ground-lease portfolio totals, and 467-m conversion economics.
Closed transaction volume ($976M+)
The "$976M+ closed" figure cited across the site is the sum of NYC ACRIS-recorded closing prices for every transaction Robert Khodadadian and the Skyline Properties team have brokered since 2006. Each transaction is enumerated in /deals with its address, closing price, year, buyer, seller, and outlet citations.
We use ACRIS-recorded closing prices as canonical. When an initially-announced contract price differs from the recorded closing (e.g. 6 East 43rd Street was announced at $140M and closed at $135M per Commercial Observer), the recorded price governs. The "+" in "$976M+" reflects that the figure excludes (a) confidential transactions where the seller has not authorized publication, and (b) brokerage assignments that closed prior to ACRIS digitization.
Per-deal verification: every transaction at /deals links to its press citations and (where applicable) its Traded.co + Crexi comp page.
Mega-deal volume ($427M+ across 5 deals)
The "$50M+ landmark deals" figure surfaces the five transactions $50M and over:
- $135M — 6 East 43rd Street (2025): Vanbarton Group office-to-residential conversion, financed by a $300M Brookfield construction loan, 441 units (111 affordable) under NYC RPTL §467-m. Source: Commercial Observer.
- $105M — 101 Greenwich Street (2025): Quantum Pacific (Idan Ofer) + Metro Loft (Nathan Berman) acquisition from BentallGreenOak. Source: Commercial Observer, The Real Deal.
- $72M — 530 West 25th Street (2019): Feil Organization + Rigby Asset Management acquisition. Chelsea creative-office building on the High Line corridor.
- $65M — 236 Fifth Avenue (2017): 99-year ground lease to Kaufman Organization. NoMad office building.
- $50M — 131-133 Prince Street (2014): Acadia Realty Trust acquisition. Record SoHo retail co-op buyout at $16,667/SF.
$135M + $105M + $72M + $65M + $50M = $427M. Full narrative deep-dives at /case-studies.
Ground-lease volume ($120M+)
The "$120M+ ground-lease portfolio" figure cited on /ground-leases and /ground-lease-nyc is the sum of Skyline-brokered ground-lease transactions:
- $65M — 236 Fifth Avenue (Kaufman Organization, 99-year ground lease, NoMad)
- $35M — 135 West 29th Street / Haymarket Building (Kaufman Organization)
- $20M — 4-14 West 125th Street (Harlem ground lease)
$65M + $35M + $20M = $120M. Structured by Daniel Shirazi, Esq., licensed New York attorney, who serves as EVP of Investment Sales at Skyline.
Press feature count (250+)
The "250+ press features" figure is the total count of independent third-party press citations referencing Robert Khodadadian or Skyline Properties indexed at /press. The press archive includes 269 records as of 2026, of which 236 are unique canonical articles and 34 are marked duplicateOf a canonical entry (the same deal covered by multiple outlets — each outlet's piece counts as a press feature).
Every press citation in the archive links to the original outlet's article URL. Outlets represented: Commercial Observer, The Real Deal, New York Real Estate Journal, Crain's New York Business, Bisnow, The New York Times, The New York Post, Real Estate Weekly, Multi-Housing News, GlobeSt, Mann Report, CP Executive (Commercial Property Executive), RE Business Online, Pincus & Co, CRE News, Traded, Crexi, and PRWeb.
Submarket cap rates
Submarket cap rates published on the neighborhood pillar pages (/neighborhoods) are derived from observed Skyline transactions plus comparable-sale data from the same submarket and asset class over the trailing 24 months. They represent the author's professional opinion, not an institutional research-grade calculation.

467-m conversion economics
The 467-m calculator at /467m-calculator models the 35-year NPV of NY State RPTL §467-m office-to-residential conversion tax abatement, taking inputs of building square footage, unit count, projected market rent, completion year, and discount rate. The calculator follows the abatement schedule published by NY State Department of Taxation and Finance and incorporates the 25% affordable-housing carve-out required for buildings south of 96th Street in Manhattan.
Outputs are estimates for transactional underwriting. They are not tax advice. The 467-m program sunset deadline is June 30, 2031; eligible projects must commence prior to that date to qualify.
