What's it worth?

Value any NYC building by the income approach.

NOI ÷ cap rate. Implied value, value per unit, value per SF — with NYC-specific defaults already filled in for Class 2 property tax, water, heat, payroll, and management. Cross-checked live against nearby ACRIS sales.

What's inside

Six ways Valuation saves you from the spreadsheet.

Income-approach valuation

NOI ÷ cap rate. Implied value, value / SF, value / unit — computed live as you type.

NYC tax auto-calculated

NYC Class 2 rates applied automatically. Override any line at any time.

Operating expenses by NYC defaults

Heat, water + sewer, insurance, payroll, management — modeled the way NYC buildings actually run.

Every revenue line

Residential (per unit or gross), commercial, office, parking, antenna, laundry, billboard — all in one place.

Per-unit or gross modes

Model individual unit rents or enter gross totals. Switch anytime without losing inputs.

How it works: Implied value = NOI ÷ cap rate. In the full tool, every EGI and OpEx line is editable; NOI recomputes too.

Paired with Comparables

Cross-check your cap rate against nearby sales.

Comparables pulls nearby ACRIS sales within your chosen radius, scores them by zoning + size + recency, and generates an AI narrative on the top matches. Use the average price / SF to sanity-check the cap rate you're applying.

Works with any building

Your own building, a listing, or a target.

Owners value their own holdings. Brokers price listings. Developers underwrite targets. Same tool, same NYC-specific defaults, same two-click workflow.
