Is Your NYC Property More Valuable To A Developer?

Buildings can be valued based on the income they generate, or based on their development potential. We help you determine which one is worth more to a prospective purchaser.

The Land Value Gap

Two Ways To Value The Same Property

What Rent Tells You

Income-based valuation using NOI and cap rates. This is what a buyer would pay for the cash flow the building generates today.

What Zoning Tells You

Land-based valuation using FAR (floor area ratio) and development comparables. This is what a buyer would pay for the unbuilt potential.

Is Your Property Under-Built?

Signs Your Site May Be Worth More As Land

Your building is only 2 to 4 stories tall, even though local zoning allows buildings of 8 to 20 stories.
Neighboring parcels have recently sold to buyers planning new construction.
Your existing structure is primarily office or commercial space rather than residential.
Current tenants are month to month, market rate, or the space sits empty.
A recent rezoning or upzoning increased the buildable potential nearby.
Your lot sits on a corner, is larger than typical, or borders parcels that could be assembled together.
