Plain-English answers on zoning, air rights, development value, and selling — written for owners, not lawyers.
Developers find land through broker relationships, off-market outreach to owners, public listings, and proprietary databases that track zoning, ownership, and underbuilt lots - many of the best sites trade before they are ever listed. For an owner, a broker's relationships can reach buyers you would never find on your own.
Developers often prefer off-market because they face less competition and can negotiate directly, but the strongest sites still attract aggressive bids whether listed or not. Preference does not equal a lower price for the seller - an owner who runs a competitive process can capture more value even from off-market-minded buyers.
A developer reaches out when your property has unused FAR, sits within an assemblage they are building, or fits a specific project pipeline - the trigger is development potential you may not be using. An unsolicited approach signals real value, and usually a reason to test the market before responding.
Brokers connect owners with developers through established relationships, knowledge of who is actively buying in each submarket, and the ability to match a site's zoning to a developer's project criteria. That targeting reaches the buyers most likely to pay a premium, which is the core value a specialized broker provides.
Developers watch for an aging owner, a long hold period, deferred maintenance, an underbuilt lot relative to its zoning, or a recent estate filing - all signals they use to time outreach. For an owner, recognizing your property already shows these signals is a reason to control the process rather than field opportunistic offers.
A developer estimates buildable square footage, projects the completed project's value, subtracts construction and soft costs and target profit, and arrives at what they can pay for the land - the residual land value. Understanding that this calculation sets their bid helps an owner see why offers vary between buyers.
Developers check whether combining adjacent lots into one zoning lot would unlock more buildable square footage, often by pooling unused FAR - an assembled site can be worth more per foot than its parts. An owner whose lot completes a developer's assemblage may command a premium above standalone value.
On a first screening, developers check zoning and FAR, lot size and shape, existing occupancy, and obvious obstacles like landmarks or environmental flags - enough to decide whether the site clears their threshold. It is a fast filter, so materials that answer these questions upfront make a real offer more likely.
A direct approach is worth a conversation, but engaging without a broker means negotiating against a professional who underwrites land daily and knows you have not tested the market - an information gap that usually costs the seller. A broker can quietly create competition so the direct offer becomes your floor, not your ceiling.
Run a structured process with a broker who brings every interested party to a single call-for-offers deadline, rather than negotiating with each separately, which lets them stay cautious. The deadline forces each developer to lead with their strongest number - see What Is a Competitive Bidding Process? for how that process works.
