What a developer would actually pay for your land.
Developers run one calculation before they knock on your door: finished value, minus construction cost, minus their profit, equals what your land is worth to them. This runs that math for you — so an unsolicited offer never catches you off guard.

This is the arithmetic a developer runs before they make you an offer. Send me the parcel and I'll tell you what the site supports and what a second developer would likely pay.
A planning estimate on adjustable assumptions — not an appraisal, feasibility study, or investment advice. Actual value depends on zoning, entitlements, site conditions, and market timing.
Frequently asked
What is residual land value?
Residual land value is what is left over for the land after you subtract construction costs and a developer’s required profit from the finished, stabilized value of a project. It is the exact math a developer runs to decide what to pay for your site — so it is the number you should know before accepting any offer.
Why would a developer’s offer be lower than this?
A developer’s offer is designed to capture the development spread for the developer, not for you. They price to raw land and keep the entitlement, construction, and lease-up profit. Knowing the residual land value shows you how much of that spread the offer is asking you to give up.
Is this an appraisal?
No. It is a planning estimate built on adjustable assumptions (finished value, construction cost, profit, density). Real numbers depend on zoning, entitlements, site conditions, and market timing — which is exactly where a broker with development experience adds value. Use it to start an informed conversation.
This is the arithmetic a developer runs before they call you
Residual land value works backwards. Take what the finished project will be worth, subtract construction, soft costs, financing, and the profit the developer requires, and whatever remains is what the land can support.
That is why an unsolicited offer arrives at the number it does. The developer has already run this. Their offer sits comfortably below the ceiling it produces, because there is no competition in the room and no reason for it to sit anywhere else.
The inputs that move it most
Density first — units or floor area permitted, height, setbacks and parking. A site is worth what can be built on it, not what stands on it. Then the gap between zoning and the future land-use designation, because value available through a rezoning belongs to whoever establishes it. Sell before it exists and the buyer captures it.
Then the quiet killers: utility capacity, traffic concurrency, drainage, wetlands and access. A parcel that cannot get the turning movement a project needs is a different asset from the one next door.
For context on how often this matters: across the tri-county commercial roll, land is assessed above the improvement on 41% of parcels and at twice the improvement on 27%. Do check that against comparable land sales rather than the assessment — the three counties allocate the split differently — but the pattern is real.
Common questions
What is residual land value?
The value of the finished project less construction, soft costs, financing and the developer's required profit. Whatever remains is what can be paid for the land, and it is the calculation behind most unsolicited offers.
Why is a developer's offer usually below this number?
Because it is a negotiation with one participant. The residual sets a ceiling; the offer sits below it. What moves the price is a second developer running the same analysis, not harder negotiating with the first.
Should I get the site entitled before selling?
It depends on time, cost and risk appetite. Entitling captures the value step but costs real money over a long period and can fail at a public hearing. A contract with a long feasibility period lets the developer pursue approvals at their cost while you keep title.
