FAQ
Manhattan development sites trade on buildable square footage, air-rights optionality, and a clean path to delivery. Here is what principals ask before they sell or acquire a site — including when a 467-m office-to-residential conversion beats ground-up construction.
A strong Manhattan development site is defined by three things: unused floor-area ratio (FAR) relative to what is already built, a zoning envelope that allows the intended use as-of-right or with an achievable bonus, and a clean assemblage or single-lot footprint large enough to support an efficient floor plate. Beyond the dirt, buyers weigh demolition or relocation cost, soft-site risk (existing tenants, rent-stabilized units, or a non-conforming structure), and air-rights availability from adjacent lots. Skyline Properties underwrites each of these before bringing a site to a developer, including assemblage plays like the $50M Acadia Realty Trust acquisition at 131-133 Prince Street in SoHo.
Manhattan development sites trade on a dollars-per-buildable-square-foot basis — total price divided by the maximum zoning floor area, net of any demolition or tenant-buyout cost. In 2026, Manhattan land commonly ranges from roughly $300 to $800 per buildable SF depending on submarket, use (condo land prices above rental land), and whether the FAR is as-of-right or requires a bonus or special permit. The price also reflects the cost and timeline to deliver a clean, buildable site. Skyline anchors land pricing to ACRIS-recorded comparable sales and a realistic development pro forma rather than aspirational asking prices.
Air rights are the unused development potential — the difference between the floor area a zoning lot is permitted and what is currently built. Those unused rights can often be transferred to an adjacent lot through a zoning-lot merger, or in special districts sold as Transferable Development Rights (TDR). Acquiring neighboring air rights can turn a modest site into a viable tower, which is why assemblage strategy is central to Manhattan development. Skyline identifies adjacent-lot FAR, models the merged envelope, and advises owners and developers on whether to buy, sell, or aggregate air rights before committing to a site.
It depends on which buyer pool values your asset more. An aging, under-built, or low-occupancy building on a high-FAR lot often sells for more to a developer who values the dirt than to an investor who values the in-place rent roll. A well-leased, fully-built asset usually sells higher as an income property. The decision also turns on tenancy — rent-stabilized units, long-term commercial leases, or a hard-to-relocate operator can make a development exit slower and riskier. Skyline runs both the income-property and development-site valuations side by side, then markets the asset to whichever pool produces the highest net proceeds.
Development sites are especially well suited to off-market sales because the value is in the dirt, not in stabilized cash flow that an open process can verify. A public listing signals to tenants, neighbors, and the market that an owner intends to redevelop — which can trigger holdout behavior, tenant organizing, or competing assemblage offers that erode the owner's leverage. A confidential, NDA-protected process run to a curated pool of qualified developers preserves negotiating position and discretion. Skyline Properties has closed Manhattan development trades quietly, including 133 Greenwich Street ($28M, 2012), 587-591 3rd Avenue ($18M, 2014), and 1055-1057 2nd Avenue ($18M, 2015).
Frequently, yes. For many older Manhattan office buildings — particularly Class B/C stock south of 96th Street — a 467-m office-to-residential conversion delivers residential units faster and at a lower basis than demolition and ground-up construction, while capturing up to a 35-year property-tax exemption. The right path depends on the building's floor plate, light-and-air, structural grid, and acquisition basis. Skyline models both the conversion and the redevelopment case, and brokered two of the defining 2025 conversion trades: the $135M Vanbarton Group acquisition of 6 East 43rd Street and the $105M Quantum Pacific and Metro Loft acquisition of 101 Greenwich Street.
