Customized canvassing is how Skyline Properties sources transactions that never reach the open market. Instead of waiting for listings, the firm builds a target map for each buyer mandate or seller profile and approaches ownership directly and quietly, with a specific thesis for why a conversation makes sense now. Most of what an off-market brokerage does runs through it.
How the process actually runs
- Define the box: asset class, submarket, size band, and structure (fee, ground lease, conversion candidate) come from a verified buyer mandate or a seller's disposition criteria. We don't prospect generically.
- Build the ownership map: public records, prior transaction history, and two decades of relationships identify who actually controls each target asset and what their holding period looks like.
- Approach with a thesis: every call opens with why this owner and why now, whether that is an expiring hold period, a conversion window like the 467-m program, or a ground-lease structure that fits a multigenerational owner's goals.
- Qualify before exposure: no owner's building is described to a buyer, and no buyer's mandate is revealed to an owner, until both sides pass qualification.
- Run the negotiation privately: pricing references closed comparables, and the process stays off listing platforms end to end.
Why it produces different outcomes
Canvassing finds the transactions that inventory-based brokerage structurally cannot: the owner who would sell at the right number but will never list; the ground-lease structure that solves an estate problem; the obsolete office building whose highest bidder turns out to be a conversion developer. Skyline Properties’ $135M sale of 6 East 43rd Street to Vanbarton for residential conversion and the $35M, 99-year Haymarket Building ground lease with The Kaufman Organization both began as direct, thesis-driven conversations. Neither was ever listed.
What owners should take from this
If your building fits an active mandate, you do not need to list it to learn its value. A confidential conversation, anchored to Skyline Properties’ closed record and run under the process above, establishes what qualified capital will actually pay, and nothing reaches the market until you decide to transact.
